The present invention relates generally to wireless networks, and more particularly to methods and apparatus for configuring, expanding and maintaining a wireless network for home or office use.
In recent years, wireless networks have emerged as flexible and cost-effective alternatives to conventional wired local area networks (LANs). At the office and in the home, people are gravitating toward use of laptops and handheld devices that they can carry with them while they do their jobs or move from the living room to the bedroom. This has led industry manufacturers to view wireless technologies as an attractive alternative to Ethernet-type LANs for home and office consumer electronics devices, such as laptop computers, Digital Versatile Disk ("DVD") players, television sets, and other media devices. Furthermore, because wireless networks obviate the need for physical wires, they can be installed relatively easily.
Wireless communication systems adapted for use in homes and office buildings typically include an access point coupled to an interactive data network (e.g., Internet) through a high-speed connection, such as a digital subscriber line (DSL) or cable modem. The access point is usually configured to have sufficient signal strength to transmit data to and receive data from remote terminals or client devices located throughout the building. For example, a portable computer in a house may include a PCMCIA card with a wireless transceiver that allows it to receive and transmit data via the access point. Data exchanged between wireless client devices and access points is generally sent in packet format. Data packets may carry information such as source address, destination address, synchronization bits, data, error correcting codes, etc.
A variety of wireless communication protocols for transmitting packets of information between wireless devices and access points have been adopted throughout the world. For example, in the United States, IEEE specification 802.11 and the Bluetooth wireless protocol have been widely used for industrial applications. IEEE specification 802.11, and Industrial, Scientific, and Medical (ISM) band networking protocols typically operate in the 2.4 GHz or 5 GHz frequency bands. In Europe, a standard known as HIPERLAN is widely used. The Wireless Asynchronous Transfer Mode (WATM) standard is another protocol under development. This latter standard defines the format of a transmission frame, within which control and data transfer functions can take place. The format and length of transmission frames may be fixed or dynamically variable.
Although traditional wireless networks work fairly well for residential Internet traffic running at data rates below 1 megabit per second (Mbps), transmission of high-bandwidth video programs is more problematic due to the much faster video data rates. High-bandwidth data transmissions can be degraded by the presence of structural obstacles (e.g., walls, floors, concrete, multiple stories, etc.), large appliances (e.g., refrigerator, oven, furnace, etc.), human traffic, conflicting devices (e.g., wireless phones, microwave ovens, neighboring networks, X10 cameras, etc.), as well as by the physical distance between the access point and the mobile terminal or other device. By way of example, an IEEE 802.11b compliant wireless transceiver may have a specified data rate of 11.0 megabits per second (Mbps), but the presence of walls in the transmission path can cause the effective data rate to drop to about 1.0 Mbps or less. Degradation of the video signal can also lead to repeated transmission re-tries, causing the video image to appear choppy. These practical limitations make present-day wireless technologies one of the most unreliable of all the networking options available for home media networks.
One proposed solution to this problem is to increase the number of access points in the home, with the various access points being interconnected by a high-speed cable wire. The drawback of this approach, however, is that it requires that cable wires be routed through the interior of the structure.
An alternative solution is to utilize wireless repeaters to extend coverage of the network throughout the building. For example, D-Link Systems, Inc., of Irvine, Calif. manufactures a 2.4 GHz wireless product that can be configured to perform either as a wireless access point, as a point-to-point bridge with another access point, as a point-to-multi-point wireless bridge, as a wireless client, or as a wireless repeater. As a wireless repeater, the product functions to re-transmit packets received from a primary access point. But the problem with these types of wireless repeaters is that they retransmit at the same frequency as the primary access point device. Consequently, because the primary access point and repeaters share the same channel, the bandwidth of the network is effectively reduced for each repeater installed. For example, if a data packet needs to be repeated (i.e., re-transmitted) three times in the same channel, each packet must wait until the previous packet has been repeated which means that the resulting bandwidth loss is 67%. So if the initial video transmission starts out at, say, 21 Mbps, the effective payload data rate at the receiver end is diminished to about 7 Mbps. Naturally, with more repeaters, more data hops are required, so the bandwidth loss becomes worse. This approach basically trades-off bandwidth for signal range—extending the range of the wireless network, but sacrificing valuable bandwidth in the process.
Still another attempted solution to the problem of wireless transmission of video data is to lower the bandwidth of the video through data compression. This technique involves compressing the video data prior to transmission, then decompressing the data after it has been received. The main drawback with compression/decompression techniques is that they tend to compromise the quality of the video image, which is unacceptable to most viewers. This approach also suffers from the problem of lost connections during transmission.
In view of the aforementioned shortcomings, there exists a strong need for a highly reliable wireless network (e.g., on a par with coaxial cable) that provides very high data rates (e.g., 30 Mbps) throughout the full coverage range of a home or building.
The present invention will be understood more fully from the detailed description that follows and from the accompanying drawings, which however, should not be taken to limit the invention to the specific embodiments shown, but are for explanation and understanding only.
The present invention is a wireless local area network (WLAN) that utilizes cellular techniques to extend the range of transmission without degrading bandwidth. The wireless network of the present invention is thus ideally suited for transmitting video programs (e.g., digitally-encoded video broadcast services, pay-per-view television, on-demand video services, etc.) throughout a house or other building, thereby creating a "media-live" environment.
In the following description numerous specific details are set forth, such as frequencies, circuits, configurations, etc., in order to provide a thorough understanding of the present invention. However, persons having ordinary skill in the communication arts will appreciate that these specific details may not be needed to practice the present invention. It should also be understood that the basic architecture and concepts disclosed can be extended to a variety of different implementations and applications. Therefore, the following description should not be considered as limiting the scope of the invention.
With reference to
Commands for one or more of these home media devices may be generated using a remote control unit 17, either through infrared (IR) or radio frequency (RF) signals. In one embodiment, wireless network 10 provides reliable, full home coverage at throughputs supporting multiple simultaneous video streams, e.g., two HDTV streams at approximately 30 Mbps; eight SDTV streams at about 16 Mbps.
According to the present invention a plurality of access points is utilized in a wireless network to provide relatively short transmission ranges that preserve bandwidth and achieve high reliability. The wireless network of the present invention implements a three-dimensional ("3-D") topology in which communications between an access point and mobile terminals or client media devices in a particular region occur at a frequency which is different than the communication frequency of a neighboring region. In specific embodiments, the 2.4 GHz and 5 GHz frequency bands are utilized for wireless transmissions. In the United States, for instance, the 2.4 GHz band provides three non-overlapping channels, whereas the 5 GHz band provides twelve non-overlapping channels for simultaneous transmission traffic. The wireless network of the present invention achieves full range coverage in the home without bandwidth loss by utilizing a different channel for each data packet hop. This feature allows repeater data packets to overlap in time, as discussed in more detail below.
In the example of
After the transmission of data packet 1, access point 20 a may immediately transmit a second source data packet ("packet 2"), followed by a third source data packet, a fourth data packet, and so on. Each of these data packets are repeated across the network in a pipeline manner by access points 20 b and 20 c, as shown in
In the 2.4 GHz band, three channels allows for three hops in any direction (including the initial transmission from the source) in three-dimensional space at maximum bandwidth. Since each hop normally can extend about 50 feet at maximum bandwidth, three hops on three different channels (one source plus two repeaters) can cover a distance of about 150 feet from source to destination. In the license-free 5 GHz band (e.g., 5725 MHz to 5850 MHz), there are currently twelve channels with upwards of 54 Mbps of bandwidth available on each channel in good transmission conditions. As with the 2.4 GHz band, each hop in the 5 GHz band will typically extend about 50 feet at maximum bandwidth, but the large number of channels permits hops to extend indefinitely. That is, in a wireless network operating in the 5 GHz band according to the present invention, repeaters extend far enough for channel reuse. This means that hops can extend the range of transmission from source to destination without limitation.
In addition to neighboring access points operating on different channels, different frequency bands may also be used during data transmission across the wireless network of the present invention. In an alternative embodiment, for instance, 5 GHz repeaters may be utilized to form an arbitrary length backbone for 2.4 GHz data traffic. This situation is illustrated in the example of
Another possibility is to use a 5 GHz device at the destination and a 2.4 GHz access point at the source or vice-versa. As long as the network is configured for communications with source-to-destination frequency band transitions of 2.4 GHz to 5 GHz, or 5 GHz to 2.4 GHz, or 2.4 GHz to 2.4 GHz on different channels (all utilizing 5 GHz for repeaters in-between), the network can provide an arbitrary length backbone for 2.4 gigahertz traffic, despite the fact there are only three 2.4 GHz channels available. In other words, the wireless network of the present invention is not limited to data transmissions confined to a single frequency band.
It is also possible to configure a wireless network in accordance with the present invention where the source and destination devices both operate at 2.4 GHz using the same channel. Such an embodiment is shown in the conceptual diagram of
With reference now to
CPU 62 controls the re-transmission of the received data packets, utilizing RAM 63 for both program execution, and for buffering of the packets as they are received from the upstream side, i.e., nearest the source, before they are sent out to the downstream side, i.e., toward the destination. Flash ROM 64 may be used to hold software and encryption key information associated with secure transmissions, for example, to insure that the network users are authorized users of satellite or cable subscriber services.
In the embodiment of
By way of example,
Other non-ISM bands wireless network protocols could be utilized as well. For example, instead of utilizing 802.11a transceivers in the 5 GHz band, the network of the present invention could be implemented using transceivers compatible with HIPERLAN2, which runs with an effective throughput of about 42 Mbps.
Transmissions between repeater unit 60 and client wireless media devices located nearby are shown at the top of
Repeater units 60 may be installed in the wireless network of the present invention after the source access point (e.g., source video receiver) has been made operational. In one embodiment, a new repeater unit 60 is first connected to the source access point or an existing repeater (one that is already plugged into an outlet and coupled to the wireless network) using a Firewire cable. The Firewire cable is connected between the existing repeater or source access point and the new repeater. Power is provided over the Firewire cable from the existing repeater or access point to the new repeater to activate the internal circuitry of the new repeater, so that encryption key information may be exchanged to allow the new repeater to securely connect to the network. Execution of program instructions for the exchange of encryption information may be initiated by the person performing the installation pressing pushbutton switch 69, located on the front side of repeater unit 60 in
After the exchange of encryption information has completed, the Firewire cable between the two devices may be disconnected. The repeater unit with the newly activated encryption key may then be plugged into an electrical outlet in any location of the home or building where the user wants the network to extend.
Once repeater unit 60 is plugged in, it immediately outputs an indication of received signal strength on LED indicator panel 71. LED indicator panel 71 provides an indication of transmission signal strength to the upstream receiver, and may be advantageously used to locate repeater unit 60 to extend the network in a home or building. If, for example, the LED output indicates a strong signal, the installer may wish to remove the repeater unit from its present wall outlet location to a location farther away from the nearest existing repeater or access point. If, upon moving to a new location, LED indicator panel 71 outputs a "weak" or a "no signal" reading, this means that the new repeater is too far away from existing connection points of the network. In either case, the installer should move the repeater unit back closer to an existing repeater or access point until a "good" or "strong" signal strength is indicated.
Another option is to provide an audio indication of the transmission signal quality, instead of a visual indication.
Once the source access point (e.g., video receiver) detects the presence a newly-activated repeater unit, it automatically self-configures the cellular repeater wireless network. This aspect of the present invention will be explained in greater detail below.
The example network shown in
With reference to the first floor plan shown in
It is appreciated that access point 85 only needs one transceiver to create the repeating wireless network shown in
Practitioners in the communications arts will also understood that nearby access points transmitting on the same channel in the first floor network shown in
Practitioners in the art will also appreciate that the tree structure of the wireless network of the present invention is well-suited to applications in which most of the bandwidth is provided from a single source (e.g., a satellite or cable feed). When the bulk of the bandwidth is from root to branch, the repeaters disposed in the branches the tree topology can share channels. When there is a lot of back-and-forth traffic, on the other hand, the repeaters in the tree structure have to operate on different channels, in case a message travels from one branch to another branch of the tree.
The self-configuring feature of the present invention is also apparent with reference to
Note that in
The circuitry for controlling the self-configuration process may either be centralized in the source access point or distributed throughout the access points comprising the wireless network. In either case, the system may proceed through a process of iteration, wherein every possible combination of channels allocated to the access points may be tried in order to find an optimal combination of frequency channels. In one embodiment, the network hops through the frequency channels automatically so that an optimal combination of frequencies may be determined. Within a matter of seconds, the network may complete iterating through all permutations of channels to identify which combination of frequencies produces the best result. One example of a best result is the highest average bandwidth from source to each destination. Another best result may be defined as one which optimizes bandwidth to certain destination devices. For instance, if a particular destination device (e.g., a video receiver) requires higher bandwidth than other destination devices, then allocation of channels may be optimized to provide higher bandwidth in the network path to the particular destination device at the expense of lower bandwidth to other devices.
The system of the present invention also functions to keep modulated power in the network to a minimum. It may be necessary in some instances, for example when transmitting through many walls to a maximum range, to use a lot of power. In other instances, a repeater is located nearby and there may be few walls to transmit through, so less transmission power is required. When the network initially turns on, the access points may transmit at maximum power to establish a maximum range of communication. However, once communications have been established with all of the repeaters in the network, the power output may be reduced to a level that provides adequate signal transmission characteristics (i.e., a threshold signal strength), but no more. In other words, the network may throttle power output, keeping it only as high as it needs to be to create a strong signal to the next repeater. One benefit of such an operation is that it reduces signal reflections that may interfere with the reception quality. Another benefit is less power consumption.
Another benefit of the power management feature of the present invention is that by having a given channel prorogate less distance, you create the opportunity to reuse that channel in the network at an earlier point in the topology than if transmissions were at maximum power.
According to one embodiment, the wireless network of the present invention automatically detects channel conflicts that arise, and adapts the network to the conflict by reconfiguring itself to avoid the conflict. That is, the access points monitor the signal quality of the wireless transmissions on a continual basis. Any disturbance or conflict that causes signal transmissions to fall below an acceptable quality level may trigger an adaptive reconfiguration process.
By way of example,
The adaptation process discussed above may be performed in a similar manner to the self-configuration process previously described. That is, all of the different possible combinations of channels may be tried until the network identifies an optimal combination that works to overcome the channel conflict without creating any new conflicts. The adaptation process may rely upon an algorithm that does not attempt to change or move channels which have already been established. In the example of
In the unlikely event that a channel conflict is truly unavoidable, i.e., no combination of channels exists that would allow the network to extend from the source to any destination without conflict (as could occur in a situation where there is heavy use of channels by neighboring networks) the wireless network of the present invention can reduce bandwidth and still maintain connectivity. Such a scenario is depicted in
In yet another embodiment of the present invention, simultaneous wireless networks may be created to run at the same time. Simultaneous wireless networks may be desirable in certain applications, say, where there are three HDTV sets each operating at 15 Mbps. If the backbone of the primary network operates at 36 Mbps, the available bandwidth is insufficient to accommodate all three screens. The solution provided by the present invention is to install a second video tuner (i.e., a second source access point) and double up the number of repeaters through each branch of the rest of the topology.
It should be understood that as long as there are a sufficient number of channels available, bandwidth can be increased arbitrarily in the arrangement of
The security features provided by the wireless network of the present invention are discussed in conjunction with the example of
In addition to encrypted data, the wireless network of the present invention may also transmit presentation layer data and information, such as overlay graphics and remote controls for interactive experiences. To put it another way, the network may also carry information both upstream and downstream.
Practitioners in the art will further appreciate that tuner 130 may also digitize analog video, decode it, and compress the received source data prior to transmission across the wireless network, in addition to receiving compressed digital video. In the case where compressed video is transmitted by tuner 130, receiver 133 decompresses the data as it is received. Alternatively, decompression circuitry may be incorporated into television 134 (or into an add-on box) that performs the same task. Receiver 133, or a wireless-enabled television 134, may identify itself as a device that requires high bandwidth to the upstream wireless repeaters 60 and tuner 130. When the network re-configures itself to avoid an interference source, it may take this requirement into consideration during channel allocation to optimize bandwidth in the network path from tuner 130 to receiver 133 or wireless-enabled television 134.
In an alternative embodiment, tuner 130 decrypts the real-time media stream as it is received from the satellite or cable service provider, and then re-encrypts that same data using a different encryption scheme that is appropriate for the wireless local area network. Thus, in this alternative embodiment, only devices properly enabled by the network are authorized to play media content received via that network. Note that because the wireless network in this embodiment of the present invention is a single or uni-cast signal, it can only be received by a properly enabled receiver that is authorized with appropriate encryption key information. In other words, the media content transmitted across the network from source to destination is not simply available to anyone who happens to have a receiver.
Still another possibility is for the cable or satellite company to grant an entitlement to tuner 130 that allows a certain limited number of streams (e.g., three or four) to be transmitted in a particular household or office environment, regardless of the number of media client devices that actually receive the media content. This is simply another way to restrict distribution of the media content.
In yet another alternate embodiment, tuner 130 receives video data packets from a DBS or digital cable TV source and buffers the packets in its internal RAM (see
Another feature of the present invention is the ability to serendipitously provide connectivity to any user who happens to be within the range of the wireless network. If, for instance, a wireless repeater or access point is mounted near a window or on the rooftop of a building, the outdoor range of the wireless network may be extended to a nearby park or other buildings (e.g., a cafķ or coffeehouse). A user who has a laptop computer configured with an existing wireless transmitter and receiver, and who happens to be within the range of the wireless network, could connect to the Internet; view a video program; listen to an audio program; or store media content on its disk drive for retrieval and play at a later time (assuming proper entitlements). In other words, the present invention provides ever greater mobility by allowing portable computer users to take media content with them.
Media content may also be downloaded from the wireless network for archival storage on a wireless disk server.
Those of ordinary skill in the art will further appreciate that the wireless network of the present invention is client device independent. It does not matter to the network what type of device is at the destination end receiving the transmitted media content. Video and graphics content carried on the WLAN of the present invention can play on multiple types of television, computers (e.g., Macintosh« or PC), different MP3 players, PDAs, digital cameras, etc. By way of example, any PC or Mac equipped with a 2.4 GHz band wireless card can detect the presence of the wireless network. Once it has detected the running wireless network, it may download a driver that contains the necessary security and protocol information for accessing the media content. Readily available software, such as RealPlayer«, QuickTime«, or Windows« MediaPlayer, may be used to play content provided through the network.
With reference now to
Data from the satellite feed is received by a tuner 140 and output to decryption circuitry 141, which may be configured to receive the latest encryption key information from a smart card 142. The decrypted digital stream output from block 141 is then re-encrypted by encryption circuitry 143 prior to being sent over the wireless network. As discussed above, the re-encryption is a type of encryption appropriate for the wireless network, not one that is locked into the satellite encryption scheme.
The architectural diagram of
Tuner 175 receives the cable feed and separates the received signal into analog or digital channels, depending on whether the tuner is tuned to an analog or digital cable channel. If it is an analog channel, the video content is first decoded by block 177 and then compressed (e.g., MPEG2 or MPEG4) by circuit block 180 prior to downstream transmission. If it is a digital channel, a QAM demodulator circuit 176 is used to demodulate the received signal prior to decryption by block 178. A point of deployment (POD) module 179, which includes the decryption keys for the commercial cable system, is shown coupled to decryption block 178. After decryption, the streaming media content is re-encrypted by block 181 before transmission downstream on the wireless network.
A 5 GHz band upstream transceiver 189 is shown in
Note that transmitter 214, receiver 215, and optional transceiver 216 are each shown connected to physically separate antennas 217 a, 217 b, and 217 c, respectively, to provide better signal isolation. Antennas 217 may be implemented as externally mounted wireless antennas, or internal antennas, each having a separate physical wire connection. Any of the previously described access points, repeaters, tuners, etc., may also be implemented with separate antennas for each different transceiver. Alternatively, transmitter 214, receiver 215, and optional transceiver 216 may all be connected to a single antenna as shown in the previous embodiments.
Transformer/power supply 201 provides supply voltages to the various internal electronic components, which include a CPU 202, a RAM 203, a Flash ROM 204, and input/output application specific integrated circuitry (I/O ASIC) 2066, each of which is shown coupled to a system bus 205. These components operate in the same manner as described in the previous embodiments. For example, a 1394 connector interface 210 provides a Firewire« port (coupled through a 1394 PHY physical interface 213) to I/O ASIC 206. A pushbutton switch 209 and an LED indicator panel 211 are also coupled to I/O ASIC 206. Switch 209 and panel 211 function in the identical manner described in conjunction with
The embodiment of
It is appreciated that since transmitter 214 and receiver 215 may be located in close physical proximity to one another, cross-channel signal interference may occur. This can be avoided by selecting transmission frequencies that are as far apart as possible. According to one embodiment of the present invention, when transmitter 214 and receiver 215 operate simultaneously it is advantageous to choose frequency channels for each that are not adjacent to one another. For example, since there are twelve channels currently available in the 5 GHz band, the architecture of the present invention attempts to choose send/receive frequency channels for transmitter 214 and receiver 215 that are as far apart as possible (e.g., channels 1 & 12), as opposed to adjacent channels (e.g., channels 1 & 2), to avoid signal interference. Channel selection for transmitter 214 and receiver 215 may be performed by CPU 202, or alternatively by another CPU (e.g., the CPU of the source access point) in the wireless network.
The same concept of utilizing a single transceiver with transmitter and receiver sections that can operate independently and simultaneously may also be applied to a wireless receiver coupled to a television or other display device. By way of example,
Receiver 220 also comprises an I/O ASIC 232 coupled to bus 221. I/O ASIC 232 includes the graphics, audio, decryption, and I/O chips for generating the output signals used to driving the television or display device. The elements 224-227 and 233-239 are the same as the corresponding elements described in conjunction with the architecture of
In the example diagrams of
As can be seen in the upstream transmission example of
For the upstream transmission example shown in
In accordance with the presently described embodiment of the invention, each of the repeaters 251-253 changes its transmitting frequency when switching the direction of transmission (i.e., from upstream to downstream, or vice-versa). For example, in the upstream transmission of
In this embodiment, the upstream transmission incurs a 50% bandwidth loss due to the repeating of channel "A" in both the transmitter and receiver sections of repeater 251. Likewise, the downstream transmission incurs a 50% bandwidth loss due to the repeating of channel "C" in repeater 253. Even though each transmission incurs a 50% bandwidth loss, this is significantly less than the 75% bandwidth loss suffered by the prior art approach described above with three repeaters. In other words, whereas the prior art approach of
An exemplary transaction across a wireless network utilizing non-access point repeaters that provide a transmission link between a source and a destination device in accordance with yet another embodiment of the present invention is shown in
It should be understood that in the particular embodiment of
The next stage in the transaction occurs when destination device 259 sends a CTS transmission back to source 256, as shown in
Once the CTS message is received by source 256, source 256 sends the data (e.g., high bandwidth video data) to destination device 259 across the wireless network. Data transmission from source 256 to destination 259 is shown occurring in
After the last data packet is received, destination device 259 sends an acknowledgement (ACK) message back to source 256 on channel "C", as shown in
Practitioners will appreciate that it is also possible to configure the receivers of each of the repeaters to also change frequency during the RTS, CTS, and ACK message transmissions in order to eliminate bandwidth loss. But again, because each of these transmissions is very brief in duration, the advantage of such implementations is minimal.
Another way to achieve high bandwidth operation in a wireless network is shown in the embodiment of
In the example of
Downstream data transmission is shown in
Practitioners in the arts will understand that, unlike repeaters 262 and 263, the two different frequency channels of destination device 264 are not utilized simultaneously. In other words, destination device 264 transmits and receives at separate times. This allows for greater cost reduction. It is further appreciated that destination device 264 could utilize a conventional transceiver capable of shifting its frequency (e.g., run on frequency channel "B" during the transmission part of the transaction, and on frequency channel "C" during the reception part of the transaction).
It is also possible to achieve upstream transmissions according to the present invention without bandwidth loss by modifying the embodiment of
The embodiment of
As can be seen, transceiver 285 and optional transceiver 286 are both coupled to system bus 275. Both transceivers are also shown coupled to an antenna 287. Alternatively, transceivers 285 and 286 may each be coupled to separate antennas.
The maximum bandwidth range is shown in
In accordance with the pipelined data transmission of the present invention, source 300 a transmits DP2 in cycle t2 on channel 1. At the same time, repeater 300 c transmits DP1 on channel 11, which is then received by destination device 305 in the same cycle. This is made possible by the fact that each repeater is located beyond the in-band interference range, yet within the range of maximum bandwidth, of nearby, i.e., adjacently-located, repeaters (as well as the source and destination devices) in the transmission chain. For instance repeater 300 b is located outside the in-band interference range of source 300 a; repeater 300 c is located outside the in-band interference range of repeater 300 b; and destination device 305 is placed outside of the in-band interference range of repeater 300 c.
Note that in the example of
A variation of the example of
The embodiment of
In the embodiment of
Finally, repeater 300 d receives DP1 on channels 7 & 8 in cycle t2 and then sends DP1 to destination device 325 in the 2.4 GHz band on channel 11 in cycle t3. The transmission of data packets DP2, DP3, and so on, continues in the same pipelined manner described above. That is, source 330 a transmits the second data packet during cycle t2 and the first half of cycle t3 as shown in
Practitioners in the art will appreciate that because repeaters 300 b and 300 c are running at twice the normal data rate, they only need half the time normally needed to transmit in the 2.4 GHz band. This time savings limits the bandwidth loss in the embodiment of
As before, each repeater 340 b-340 f is located outside of the in-band interference range 341 of other neighboring repeaters, as well as that of the source device 340 a. Destination device 345 is also located beyond the in-band interference range 341 of repeater 340 f. At the same time, each repeater (and the source and destination devices) is located within its neighboring device's maximum bandwidth range 342. By way of example, repeater 340 b is located within the maximum bandwidth ranges 342 a & 342 c, and outside of the in-band interference ranges 341 a & 341 c, of source device 340 a and repeater 340 c, respectively.
At any given moment, only one device in the wireless network of
It should be understood that elements of the present invention may also be provided as a computer program product which may include a machine-readable medium having stored thereon instructions which may be used to program a computer (or other electronic device) to perform a process. The machine-readable medium may include, but is not limited to, floppy diskettes, optical disks, CD-ROMs, and magneto-optical disks, ROMs, RAMs, EPROMs, EEPROMs, magnet or optical cards, propagation media or other type of media/machine-readable medium suitable for storing electronic instructions.

OSHA News Release - (Archived) Table of Contents
OSHA Trade Release
U.S. Department of Labor
Occupational Safety and Health Administration
Office of Communications
Washington, D.C.
For Immediate Release
Friday, January 17, 2003
Contact: William Wright
Phone: (202) 693-1999
SAN DIEGO -- The Occupational Safety and Health Administration and the Port of San Diego Ship Repair Association (PSDSRA) are teaming up to protect shipyard workers at the port, according to an announcement today by OSHA Administrator John L. Henshaw. OSHA and the PSDSRA, which represents more than 30 ship-repair companies at the port, signed a partnership agreement today to work together to eliminate the risk of catastrophic accidents and prevent serious injuries and illnesses to workers. About 95 percent of the work performed by these companies is on U.S. Navy vessels at the port.
"Shipyards can be highly hazardous workplaces," Henshaw said. "It is precisely this type of commitment on the part of employer groups that we need to help companies reduce injuries and illnesses and assure safer workplaces for their employees."
Employers participating in the partnership with OSHA must make an up-front commitment at their highest executive levels to a formal safety and health program with employee participation. The companies must establish joint employer/employee safety and health committees that include worker participation in several areas, including OSHA inspections. Employers must also commit to having a full-time employee with safety and health responsibility, including authority to make safety and health corrections and to shut down operations that pose an imminent danger risk.
Participating companies also agree to train workers on fire and emergency procedures, hazard communications and personal protective equipment, with special emphasis on respiratory protection and noise, and make Material Safety Data Sheets available to any requesting employee. The companies also agree to train all affected personnel on aspects of confined space entry, a particular hazard in the ship repair industry.
Other expectations of the partnership include employer-conducted workplace safety inspections no less than once a month and notification to all affected employees of any hazards identified during those inspections. Employers also agree to train their workforce in the details of their safety and health programs, their rights and responsibilities in maintaining a safe and healthful workplace, and on the procedures to identify and correct hazards in their work areas.
For participating companies who meet the intent of the partnership, OSHA will conduct focused verification inspections instead of programmed inspections, and will use inspectors trained in the terms of the partnership. The agency also will help participating companies with training, and give technical advice, publications and training materials to employers who request the assistance.
OSHA is dedicated to saving lives, preventing injuries and illnesses and protecting America's workers. Safety and health add value to business, the workplace and life. For more information, visit www.osha.gov.
U.S. Labor Department news releases are accessible on the Internet at www.dol.gov. The information in this release will be made available in alternative format upon request (large print, Braille, audio tape or disc) from the COAST office. Please specify which news release when placing your request. Call 202-693-7773 or TTY 202-693-7755.

The Top 5 First-Date Blunders
3- Do not brag. Women have heard it all and they've heard it all a thousand times. Every time you start overselling yourself, you become less attractive. Let her slowly discover what a great guy you are. Rather than seeking approval and trying to impress her, allow her to experience you as an enigmatic Mystery Man whom she can't quite figure out. That will raise her Interest Level in a way that hearing about your various athletic or monetary accomplishments never will.
4- Keep the conversation light and positive. So often, men, without thinking and without even knowing what they're doing, lead the conversation into heavy, negative topics. There is no constructive reason for doing this. It's a bummer. It's a bring down. It's not romantic! Don't talk about terrorism or SARS or what a jerk your boss is. Don't recount the details of your last painful breakup. Lay off the heavy subjects!
5- Do not talk about sex. Women are sick of hearing about it. Every other guy talks about it, but you're not going to. You're going to be different. You're not going to try to impress her with what a sexy, sexual guy you are. You're not going to drop hints and make innuendoes in an attempt to signal to her that you're the greatest lover in the metropolitan Cleveland area. No. You're going to remain cool and classy. When you talk about sex on a first date, you attack her comfort level and why the hell would you want to do that?
So there you have it, men. Now go out and field-test these suggestions on your next few dates and report back to me.
Remember guys; if you do what's right, she can't get rid of you.

Ratings for Dr. Lionel P. Ng
AS always.... Dr.Ng is the best ped. As everyone above said, he is extremely attentive and never rush his patient. He is open to any question and answer it one by one and make sure we understand. I wish I am as patience as he is. Youare teh best Dr. Ng and Jessie the head nurse !!!!! Long live Dr. Ng
Wow, we love him, I have looked for a good ped for a Long time, he actually spends time with you and cares about prevention and the way he communicates with the children is really special. He really cares and he cares about prevention which is awsome. His staff is really on top of it and friendly and nice. We didn't have to wait like all the other peds. that would over book. And the office is clean! This is a A+ ped and we will be with him for a long time. I can't say enough about how impressed I am with and most of all my daughter really liked him.
Dr. Ng is very good. But the front office staffers are the problem. Usual wait time when calling in is over 30 minute. They are unprofessional, unhelpful, and just plan don't care. Being with Dr. Ng for over 20 years. However, I have had it with their staffers
Excellent pediatrician! Truly attentive to needs. My son loves visiting him! Dr. Ng takes a more realistic approach to medicine.
EXTREMELY HELPFUL! You can see that he actually cares about his patients. He is also more than happy to spend the extra time to answer questions. He's also very patient and tells you how to prevent your problems or illnesses. Definitely recommended!

Testing and correcting hearing loss has greatly improved
Q I'm losing my hearing so my doctor has scheduled an audiological evaluation. What will this evaluation tell me?
A An audiological evaluation identifies the severity of your hearing loss and the frequency range in which it occurs. This information may help identify the cause of your hearing loss. It's also essential for determining whether you could benefit from a hearing aid and, if so, which style and type would help the most.
When a sound wave enters your ear, it hits the eardrum. Several tiny bones transmit sound waves from the eardrum through fluid, into the inner ear. There lies a snail-shaped organ called the cochlea that is covered with tiny hairs. These hairs generate electrical signals that travel along the hearing nerve (the auditory nerve) to the brain.
The evaluation is done by a hearing specialist, or audiologist, in a specially constructed booth that shuts out all unwanted noise. It tests the different parts of the ear that are necessary for hearing:
- Pure-tone test. Each of your ears, in turn, is exposed to sounds of different frequencies and decibel levels. (Frequency is the pitch of a sound. A decibel is the measurement of the loudness of a sound.)
- Next is a bone-conduction test. This test helps establish whether your hearing loss is primarily sensorineural (caused by damage to the cochlea, hair cells or auditory nerve) or conductive (caused by a blockage of sound transmission through your outer or middle ear), or a combination of the two. This test will also help determine whether your hearing loss can be medically corrected, and the kind of hearing aid you need.
Two additional tests will evaluate how well you hear and understand spoken words:
- Speech reception threshold test. You will hear words, instead of tones, through your earphones. The words start out loud and gradually get softer. The test identifies the decibel level at which you can understand and repeat only half of the words.
- Speech discrimination test. With age, many people can hear words loudly but not clearly. A speech discrimination test assesses how well you understand words.
Today's technology for testing your hearing has improved greatly since I was in medical school.

NRL SuperCoach Last Word - Rd 6
- From: News Corp Australia Network
- April 11, 2013
SUPERCOACH superstar Paul Gallen has bottomed out in price, but is he worth the cash even at the discount?
As predicted, Gallen's price has dropped nearly $50,000 over the opening rounds, with reduced minutes and the new 8m rule eating into his scores.
In the process, Gallen has lost his mantle as the best player in SuperCoach, now ranking fourth.
But even at his current reduced price, it's tough to fit Gallen into your team, especially when you consider the other options.
Robbie Farah, the best player in SuperCoach this year, averages eight points more but costs $43,000 less.
Cameron Smith, the second best player in SuperCoach this year, averages five points more but costs $6,000 less.
Trent Merrin, the third best player in SuperCoach this year, averages one point more but costs $38,000 less.
Farah (three games), Smith (four games), Merrin (three games) and Gallen (three games) will all miss NRL games over Origin.
Other alternatives to Gallen include Sonny Bill Williams, Aaron Woods and Andrew Fifita.
All average slightly less than Gallen but could be more valuable given their availability over Origin.
Williams won't play Origin as he's a Kiwi, Fifita is only an Origin outsider, while Woods would be higher risk given he's a genuine chance of Origin selection.
But perhaps the most intriguing alternative to Gallen is Sam Burgess.
The South Sydney superstar has averaged just five points less than Gallen in the last three weeks but costs a massive $100,000 less.
He will also be the most sought after player in the comp over the rep period given he won't play Origin (he's English) and only has one bye that falls on a tough week – and that's not until round 18, which is an eternity away in SuperCoach terms.
To free up money for purchasing big guns like Burgess and co, look to downgrade to cheapies including Jack Stockwell, James Tedesco, Isaac Liu and Ngani Laumape.
Also keep an eye on future buys. Jarryd Hayne, Ben Barba and Greg Inglis will be very cheap over the coming rounds, while Feleti Mate, Johnathan Thurston, Corey Parker and Issac Luke are bargains this week.
Player of the round
Feleti Mateo
Mateo has dropped $81,500 but is one of the best SuperCoach players of all time and a steal at the price.
Jack Stockwell
One of the better cheapies this season given he has a 45 average, good job security (Michael Weyman not due back until round eight) and a great bye schedule.
Ryan James
The in-form Titan's price will peak soon, but he may be worth holding onto for the all-important round 12 – the season's first tough bye week.
Justin Horo
It's time to start selling early season cheapies who are reaching their peak and won't play in round 12. Justin Horo and Jacob Loko are examples.
Winning tips
"With the rep season only a few weeks away you should look at starting to prepare your side to overcome the bye rounds and have 17 playing in your side over the Origin period" - Ken Billingham (2012 winner)
"Now could be the time to begin preparations for picking up fallen guns in the coming weeks. Look at trading out fattened cows to the likes of Stockwell to build the bank ready for players such as Hayne, Inglis, Barba, Sutton or Hoffman." - Martin Bigg (2011 winner)
"There are some proven guns available over the next few weeks at very low prices. Thurston and Mateo this week, Hayne next week. Barring injury, all three will average well by year's end" – Matt Mullen (2009 winner)

Keystone Academy was founded in 1868 by Dr. John Howard Harris. The Academy was originally chartered by the Commonwealth of Pennsylvania in 1868, with instruction beginning the following year in the local Baptist church in Factoryville. At the time it was chartered, Keystone Academy was the only high school between Binghamton, New York and Scranton, Pennsylvania. In 1934, Keystone Academy was rechartered as Scranton-Keystone Junior College. In 1944, the name of the College was shortened to Keystone Junior College. The current name Keystone College was adopted in 1995. In 1998, the College received formal approval from the Pennsylvania Department of Education to offer baccalaureate degree programs. In 2014, Keystone received approval to offer master's degrees.

Jelly Super
From the Super Mario Wiki
Jump to: navigation, search
Retrieved from "http://www.mariowiki.com/index.php?title=Jelly_Super&oldid=2000833"
The Jelly Super is yet another one of Tayce T.'s and Zess T.'s culinary masterpieces which appears in the Paper Mario series. It appears to be a blue-capped mushroom with bright yellow jelly poured over it. By mixing a Jammin' Jelly with either a Life Shroom, a Super Shroom, or a Volt Shroom, they can create it. It restores ten HP and fifty FP.

yeah. like if they had the oil derrick as a multiplayer stage, there should be a spot were you call the leviathan using this trust siren thing. the leviathan appears, and would circle the map and just lay waste to everybody else (or everybody on the enemy team). like it would blast people at random, grab people and throw/eat them. it would be sick.
i assure you, im not tconslayer. i havent been on this board in a while.
maybe it would just be it's tentacles that circle the map. like the tentacles would pick people off randomly, then for the big finaly his head pops out in an area were there are the most players, shoots fire for a few seconds, then grabs an unlucky player in his mouth before leaving(if a player is in range of his mouth)

Hey all! My DD was is 8 months now, and I am still bf during the day, but she is sleeping about 13 hours at night now. I started my period again last month. My question is has anyones cycle changed after giving birth? I had a 30 day cycle before my pregnancy, and I don't know if it is going to be the same now. I ask because my last period was 5/26, and right now I am having early pregnancy symptoms. They include cramping, bloating, frequent urination, tender breasts, mood swings, crazy thirsty, nausea in the mornings, raised temp, and DD doesn't seem to like my milk right now.
I don't know when I am supposed to start, because I don't know how long my cycle is going to be now.
