Part BACKGROUND OF THE INVENTION: Technical Field of the Invention The present invention relates to wireless communication devices. Description of Related Art As is known, wireless communication devices are commonly used to access long range communication networks as well as broadband data networks that provide text messaging, email services, Internet access and enhanced features such as streaming audio and video, television service, etc., in accordance with international wireless communications standards such as 2G, 2.5G, 3G and 4G. Examples of such networks include wireless telephone networks that operate cellular, personal communications service (PCS), general packet radio service (GPRS), global system for mobile communications (GSM), and integrated digital enhanced network (iDEN). Many wireless telephones have operating systems that can run applications that perform additional features and functions. Apart from strictly wireless telephony and messaging, wireless telephones have become general platforms for a plethora of functions associated with, for example, navigational systems, social networking, electronic organizers, audio/video players, shopping tools, and electronic games. Users have the ability to choose a wireless telephone and associated applications that meet the particular needs of that user. Consequently, the wireless telephone has, in some ways, become an important device for many aspects of the user's life. Misplacing a user's wireless telephone can be an annoying experience. Further, while a wide range of wireless telephones and applications are available today, other functions and features are desirable, particularly for use in conjunction with other wireless devices. The disadvantages of conventional approaches will be evident to one skilled in the art when presented the disclosure that follows. Part BRIEF SUMMARY OF THE INVENTION: The present invention is directed to various system, apparatus and methods of operation that are further described in the following Brief Description of the Drawings, the Detailed Description of the Invention, and the claims. Other features and advantages of the present invention will become apparent from the following detailed description of the invention made with reference to the accompanying drawings. Part DETAILED DESCRIPTION OF THE INVENTION: FIG. 1 presents a pictorial representation of a location system for use with a handheld wireless communication device 110 in accordance with an embodiment of the present invention. In particular, a handheld wireless communication device 110, such as a smart phone, digital book, netbook, personal computer with wireless data communication or other wireless communication device that includes a wireless transceiver for communicating over a long range wireless network such as a cellular, PCS, CDMA, GPRS, GSM, iDEN or other wireless communications network and/or a short-range wireless network such as an IEEE 802.11 compatible network, a Wimax network, another wireless local area network connection or other communications link. Handheld wireless communication device 110 is capable of engaging in wireless communications such as sending and receiving telephone calls and/or wireless data in conjunction with text messages such as emails, short message service (SMS) messages, pages and other data messages that may include multimedia attachments, such as documents, audio files, video files, images and other graphics. Handheld wireless communication device 110 includes one or more processing devices for executing other applications and a user interface that includes, for example, buttons, a display screen such as a touch screen, a speaker, a microphone, a camera for capturing still and/or video images and/or other user interface devices. Wireless device 120 is shown that includes a user interface that includes push buttons 10, a light emitter 14 such as a light emitting diode (LED) or other emitter, and sound emitter 12 such as a beeper, buzzer, speaker or other audio device. While particular user interface devices are shown, the wireless device can similarly include other devices such as a touch screen or other display screen, a thumb wheel, trackball, and/or other input or output devices. The user interface of the wireless device 120 generates a location request signal in response to an indication from a user by for instance, pushing one of the push buttons 10. Wireless device 120 further includes a short-range wireless transmitter that transmits an RF paging signal, such as paging signal 16 in response to the location request signal. The short-range wireless transmitter can be part of a transceiver that operates in conjunction with a communication standard such as 802.11, Bluetooth, ZigBee, ultra-wideband, Wimax or other standard short or medium range communication protocol, or other protocol. Adjunct device 100 includes a housing that is coupleable to the handheld wireless communication device 110 via a communication port of the handheld wireless communication device 110. The adjunct device 100 includes a short-range wireless receiver that receives the RF paging signal, such as paging signal 16. The short-range wireless receiver of adjunct 100 can also be part of a transceiver that operates in conjunction with a communication standard such as 802.11, Bluetooth, ZigBee, ultra-wideband, Wimax or other standard short or medium range communication protocol, or other protocol. In particular, the short-range wireless receiver of adjunct device 100 is configured to receive the paging signal 16 generated by wireless device 120. Adjunct device includes its own user interface having push buttons 20, sound emitter 22 and light emitter 24 that emit audio and/or visual alert signals in response to the paging signal 16 to assist the user in locating the handheld wireless communication device. As with the user interface of wireless device 120, the user interface of adjunct device 100 can similarly include other devices such as a touch screen or other display screen, a thumb wheel, trackball, and/or other input or output devices. In operation, a user can attach the adjunct device 100 to his or her handheld wireless communication device 110. If the handheld wireless communication device 110 is lost or mislaid, the user can locate the handheld wireless communication device by activating a paging button on the wireless device 120 that causes paging signal 16 to be broadcast. The adjunct device 100 responds to the paging signal 16 by flashing light emitter 24 and/or emitting a loud sound such as a beeping, buzzing or other alarm signal via sound emitter 22. The user can locate the handheld wireless communication device 110 by homing in on the visual and/or audio emissions. The further operation of wireless device 120 and adjunct device 100, including several optional implementations, different features and functions spanning complementary embodiments are presented in conjunction with FIGS. 2-40 that follow. FIGS. 2 and 3 present pictorial representations of handheld wireless communication device 110 and adjunct device 100 in accordance with an embodiment of the present invention. As shown in FIG. 2, adjunct device 100 and handheld wireless communication device 110 are decoupled. Handheld wireless communication device 110 includes a communication port 26′ and adjunct device 100 includes a mating plug 26 for coupling the adjunct device 100 to the communication port 26′ of handheld wireless communication device 110. In an embodiment of the present invention, the communication port 26′ and plug 26 are configured in conjunction with a standard interface such as universal serial bus (USB), Firewire, or other standard interface, however, a device specific communication port such as an Apple iPod/iPhone port, a Motorola communication port or other communication port can likewise be employed. Further, while a physical connection is shown, a wireless connection, such as a Bluetooth link, 802.11 compatible link, an RFID connection or other wireless connection can be employed in accordance with alternative embodiments. As shown in FIG. 3, adjunct device 100 is coupled to the handheld wireless communication device 110 by plug 26 being inserted in communication port 26′. Further, adjunct device 100 includes its own communication port 28′ for coupling, via a mating plug 28, the adjunct device 100 to an external device 25, such as a computer or other host device, external charger or peripheral device. In an embodiment of the present invention, the communication port 28′ and plug 28 are configured in conjunction with a standard interface such as universal serial bus (USB), Firewire, or other standard interface, however, a device specific communication port such as an Apple iPod/iPhone port, a Motorola communication port or other communication port can likewise be employed. In an embodiment of the present invention, the adjunct device passes signaling between the external device 25 and the handheld wireless communication device 110 including, for instance, charging signals from the external connection and data communicated between the handheld wireless communication device 110 and the external device 25. In this fashion, the external device can communicate with and/or charge the handheld wireless communication device with the adjunct device 100 attached, via pass through of signals from plug 28 to communication port 26′. It should be noted however, that while communication ports 28′ and 26′ can share a common physical configuration, in another embodiment of the present invention, the communication ports 28′ and 26′ can be implemented via different physical configurations. For example, communication port 26′ can be implemented via a device specific port that carries USB formatted data and charging signals and communication port 28′ can be implemented via a standard USB port. Other examples are likewise possible. In an embodiment of the present invention, when the adjunct device 100 is coupled to handheld wireless communication device 110, the adjunct device 100 initiates communication via the communication port 26′ to determine if an application is loaded in the handheld wireless communication device 110—to support the interaction with the adjunct device 100. Examples of such applications include a location application or other application that operates in conjunction with the adjunct 100. If no such application is detected, the adjunct 100 can communicate via communication port 26′ to initiate a download of such an application directly or to send the browser of the handheld wireless communication device 110 to a website store at a remote server or other location where supporting applications can be browsed, purchased or otherwise selected for download to the handheld wireless communication device 110. In a further embodiment of the present invention, when a supporting application is loaded in handheld wireless communication device 110, the handheld wireless communication device 110 initiates communications via the communication port 26′ to determine if an adjunct device 100 is coupled thereto or whether or not an adjunct device has never been coupled thereto. If no such adjunct device 100 is detected, the application can instruct the user to connect the adjunct device 100. Further, the application can, in response to user selection and/or an indication that an adjunct device has not been previously coupled to the handheld wireless communication device 110, automatically direct a browser of the handheld wireless communication device 110 to a web site store at a remote server or other location where a supporting adjunct devices 100 can be selected and purchased, in order to facilitate the purchase of an adjunct device, via the handheld wireless communication device 110. In a further embodiment, the application maintains a flag that indicates if an adjunct device 100 has previously been connected. In response to an indication that an adjunct device has not been previously coupled to the handheld wireless communication device 110, the application can automatically direct a browser of the handheld wireless communication device 110 to a website store at a remote server or other location where a supporting adjunct devices 100 can be selected and purchased, in order to facilitate the purchase of an adjunct device, via the handheld wireless communication device 110. FIG. 4 presents a pictorial representation of a location system for use with a handheld wireless communication device 110 in accordance with an embodiment of the present invention. In particular, adjunct device 100 and wireless device 120 can operate in a reciprocal fashion to locate wireless device 120. In particular, wireless device 120 includes a housing that is attachable to or includes a ring, clip or other fastener that can be coupled to key 30 as shown or to another personal object such as a coat, a person, a pet or other thing. Further, wireless device 120 can be embodied as a card or other device that can be slipped into a wallet, an article of clothing, a bag or other thing to be located. In any of these cases, the wireless device 120 includes its own short-range wireless receiver that receives a paging signal 112 transmitted by adjunct device 110. In response to the paging signal 112, a light or sound emitter of wireless device 120 emits a detectable alert signal that helps the user locate the personal object. In an embodiment of the present invention, the adjunct device 100 operates in a similar fashion to wireless device 120 to initiate the paging signal 112. In particular, the transmission of paging signal 112 can be initiated by pressing a button or otherwise interacting with the user interface of adjunct 100. In a further embodiment, handheld wireless communication device 100 includes an interactive application that generates application data that is passed to adjunct device 100 via the communication port of the handheld wireless communication device 100. Adjunct device 100 responds to such application data by initiating the transmission of the paging signal 112. In either case, a user of handheld wireless communication device 110 that wishes to locate his or her key 30, or other object coupled to wireless device 120, initiates the paging signal 112. The user can then locate the wireless device 120 and corresponding object by homing in on the visual and/or audio emissions of the wireless device 120. FIG. 5 presents a schematic block diagram of a wireless device 120 and adjunct device 100 in accordance with an embodiment of the present invention. In particular, wireless device 120 includes short-range wireless transceiver 130 coupled to antenna 138, processing module 131, user interface 132 and memory 133. While not expressly shown, wireless device 120 can include a replaceable battery for powering the components of wireless device 120. In the alternative, wireless device 120 can include a battery that is rechargeable via an external charging port, for powering the components of wireless device 120. Adjunct device 100 includes short-range wireless transceiver 140 coupled to antenna 148, processing module 141, user interface 142 and memory 143, device interface 144, and battery 146. The processing modules 131 and 141 control the operation of the wireless device 120 and adjunct device 100, respectively and provide further functionality described in conjunction with, and as a supplement to, the functions provided by the other components of wireless device 120 and adjunct device 100. As discussed in conjunction with FIGS. 1-4, the short-range wireless transceivers 130 and 140 each can be implemented via a transceiver that operates in conjunction with a communication standard such as 802.11, Bluetooth, ZigBee, ultra-wideband, Wimax or other standard short or medium range communication protocol, or other protocol. User interfaces 132 and 142 each can contain one or more push buttons, a sound emitter, light emitter, a touch screen or other display screen, a thumb wheel, trackball, and/or other user interface devices. The processing module 131 can be implemented using a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions that are stored in memory, such as memory 133. Note that when the processing module 131 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory storing the corresponding operational instructions may be embedded within, or external to, the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Further note that, the memory module 133 stores, and the processing module 131 executes, operational instructions corresponding to at least some of the steps and/or functions illustrated herein. The memory module 133 may be a single memory device or a plurality of memory devices. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, cache memory, and/or any device that stores digital information. While the components of wireless device 120 are shown as being coupled by a particular bus structure, other architectures are likewise possible that include additional data busses and/or direct connectivity between components. Wireless device 120 can include additional components that are not expressly shown. Likewise, the processing module 141 can be implemented using a microprocessor, micro-controller, digital signal processor, microcomputer, central processing unit, field programmable gate array, programmable logic device, state machine, logic circuitry, analog circuitry, digital circuitry, and/or any device that manipulates signals (analog and/or digital) based on operational instructions that are stored in memory, such as memory 143. Note that when the processing module 141 implements one or more of its functions via a state machine, analog circuitry, digital circuitry, and/or logic circuitry, the memory storing the corresponding operational instructions may be embedded within, or external to, the circuitry comprising the state machine, analog circuitry, digital circuitry, and/or logic circuitry. Further note that, the memory module 143 stores, and the processing module 141 executes, operational instructions corresponding to at least some of the steps and/or functions illustrated herein. The memory module 143 may be a single memory device or a plurality of memory devices. Such a memory device may be a read-only memory, random access memory, volatile memory, non-volatile memory, static memory, dynamic memory, flash memory, cache memory, and/or any device that stores digital information. While the components of adjunct device 100 are shown as being coupled by a particular bus structure, other architectures are likewise possible that include additional data busses and/or direct connectivity between components. Adjunct device 100 can include additional components that are not expressly shown. As shown, the adjunct device includes a battery 146 that is separate from the battery of the handheld wireless communication device 110 and can supply power to short-range wireless transceiver 140, processing module 141, user interface 142, memory 143, and device interface 144 in conjunction with a power management circuit, one or more voltage regulators or other supply circuitry. By being separately powered from the handheld wireless communication device 110, the adjunct 100 can operate even if the battery of the handheld wireless communication device is discharged. In this fashion, the user can still page the adjunct device 100 to locate the handheld wireless communication device 110 when the battery of the handheld wireless communication device is discharged. Device interface 144 provides an interface between the adjunct device 100 and the handheld wireless communication device 110 and an external device 25, such as a computer or other host device, peripheral or charging unit. As previously discussed in conjunction with FIGS. 1-4, the housing of adjunct device 100 includes a plug, such as plug 26, or other coupling device for connection to the communication port 26′ of the handheld wireless communication device 110. In addition, the housing of adjunct device 100 further includes its own communication port, such as communication port 28 or other coupler for connecting to an external device 25. Device interface 144 is coupled to the communication port 28 that operates as a charging port. When adjunct device 100 is connected to an external source of power, such as external device 25, device interface 144 couples a power signal from the external power source to charge the battery 146. In addition, the device interface 144 couples the power signal from the external power source to the communication port of the handheld wireless communication device 110 to charge the battery of the handheld wireless communication device. In this fashion, both the handheld wireless communication device 110 and the adjunct device 100 can be charged at the same time. Further, the handheld wireless communication device 110 can be charged while the devices are still coupled—without removing the adjunct device 100 from the handheld wireless communication device 110. While the battery 146 is separate from the battery of the handheld wireless communication device 110, in an embodiment of the present invention, the device interface 144 is switchable between an auxiliary power mode and a battery isolation mode. In the battery isolation mode, the device interface 144 decouples the battery 146 from the battery of the handheld wireless communication device 110, for instance, to preserve the charge of battery 146 for operation even if the battery of the handheld wireless communication device 110 is completely or substantially discharged. In the auxiliary power mode, the device interface 144 couples the power from the battery 146 to the handheld wireless communication device 110 via the communication port to charge the battery of the handheld wireless communication device 110. In this fashion, the user of the handheld wireless communication device 110 at or near a discharged state of the handheld wireless communication device battery could opt to draw power from the battery 146. In an embodiment of the present invention, signaling from user interface 142 could be used to switch the device interface 144 between the battery isolation mode and the auxiliary power mode. Alternatively or in addition, signaling received from the handheld wireless communication device via the communication port, or remotely from wireless device 120, could be used to switch the device interface 144 between the battery isolation mode and the auxiliary power mode. Device interface 144 includes one or more switches, transistors, relays, or other circuitry for selectively directing the flow of power between the external device 25, the battery 146, and the handheld wireless communication device 110 as previously described. In addition, the device interface 144 includes one or more signal paths, buffers or other circuitry to couple communications between the communication port of the adjunct device 110 and the communication port of the handheld wireless communication device 110 to pass through communications between the handheld wireless communication device 110 and an external device 25. In addition, the device interface 144 can send and receive data from the handheld wireless communication device 110 for communication between the adjunct device 100 and handheld wireless communication device 110. FIG. 6 presents a pictorial representation of a location system for use with a handheld wireless communication device 110 in accordance with an embodiment of the present invention. In this embodiment, adjunct device 100 operates as previously described to transmit a paging signal 112. In this embodiment however, wireless device 120 transmits a location signal 114 via short-range wireless transceiver 130, such as a beacon signal or other location signal. Adjunct device 100 aids the user of handheld wireless communication device 110 in homing in on the location signal 114 based on the signal strength of the location signal 114 as received by short-range wireless transceiver 140. In an embodiment of the present invention, the handheld wireless communication device 110 executes a location application that operates under user control to initiate the transmission of paging signal 112 to locate key or keys 30 or other object associated with wireless device 120. The signal strength of the location signal 114 from short-range wireless transceiver 140 is converted to signal strength data by processor 141 and sent to handheld wireless communication device 110 via device interface 144 and the communication port of the handheld wireless communication device 110. The signal strength data is used by the location application to generate a graphical user interface including display screen 150. As shown, display screen 150 includes an indication 152 of the particular object being located and a visual signal strength indication 154. In this fashion, the user can move around with the handheld wireless communication device 110 and hunt for the key or keys 30, guided by changes in the visual signal strength indication 154. In particular, the user of handheld wireless communication device 110 can move about, seeking to maximize the visual signal strength indication 154 until the key or keys 30 are located. While signal strength is described above as a measure of approximate distance to a remote device, the time of flight methodology described in conjunction with FIG. 37 or other distance approximations can likewise be employed. FIG. 7 presents a graphical representation of an antenna pattern in accordance with an embodiment of the present invention. A possible reception pattern of antenna 148 of adjunct device 100 is shown. The antenna pattern 160 is shown in two dimensions, corresponding to, for instance, the horizontal plane of the user. In particular, antenna 148 can include a pair of loop antennas, monopoles or dipoles or other antenna configurations that are aligned in position and phase to have a directional pattern that includes a single null. While a cardioid pattern is presented, other antenna patterns with a single null or with multiple nulls, such as multiple closely spaced nulls may also be employed. As previously discussed, the short-range wireless transceiver 140 generates signal strength in response to the location signal 114 from wireless device 120. The signal strength is used to generate signal strength data that is communicated to the location application of handheld wireless communication device 110 via the communication port of the handheld wireless communication device. The use of a directional antenna in the implementation of antenna 148 can assist the location application in determining a direction to the wireless device 120. For example, the user can change the orientation of the handheld wireless communication device to determine the direction to the wireless device 120. The location application can detect when the orientation of the handheld wireless communication device corresponds to the direction of the wireless device, based on the signal strength data. When the null direction of the antenna 148 is pointing toward the wireless device 120, a null signal strength reading will occur. The location application can indicate a match to the user to inform him or her that the handheld wireless communication device 110 is pointed toward the wireless device 120. In an alternative embodiment, the user is instructed to “turn around” to gather 360 degrees of directional data. The signal strength data can be analyzed in conjunction with one or more orientation sensors of the handheld wireless communication device 110, to determine a direction to the wireless device 120. In particular, the location application can determine the particular orientation of the device corresponding to the point where the null of antenna pattern 160 is aligned with the direction to the wireless device 120, and feedback that direction to the user via a directional indicator. In an alternative embodiment, the antenna 148 includes a steerable pattern 150 that includes a steerable null. The location application of handheld wireless communication device 110 can, for example, instruct the user to stand still while the short-range wireless transceiver 140 completes a directional sweep. The location application sends application data to the adjunct device via device interface 144 that instructs the processor 141 to command the programmable antenna to sweep the null direction by 360 degrees and to collect corresponding signal strength data. Analysis of the signal strength data by the location application can be used to determine the direction to the wireless device 120 based on the direction corresponding to the null. Feedback of that direction can be provided to the user via a directional indicator generated by the location application. Further discussion of these features including several different embodiments and optional features are discussed in conjunction with FIGS. 8-15 that follow. FIG. 8 presents a pictorial representation of handheld wireless communication device 110 and adjunct device 100 in accordance with an embodiment of the present invention. In particular, a display screen 162 is shown that includes a signal strength indication 164 and an indication of direction 166 that can be used in conjunction with the location application examples discussed in association with FIG. 7. It should be noted that the location application of handheld wireless communication device 110 can operate to invert the signal strength data to generate the signal strength indication 164 so that when the null direction of the antenna pattern 160 is aligned with direction to wireless device 120, the low signal strength caused by the null is translated into a high signal strength indication, indicating to the user the device is pointed in the right direction. In this particular embodiment, the indication of direction 166 is fixed, and is pointed in the null direction of the antenna 148. As the user changes the orientation of the handheld wireless communication device 110, the (inverted) signal strength indication 164 varies. When the inverted signal strength indication 164 peaks, this indicates that the null direction of the antenna 148 (and the indication of direction 166) is pointing toward the wireless device 120. FIG. 9 presents a schematic block diagram of an antenna 148 in accordance with an embodiment of the present invention. In particular, antenna 148 includes two separate antennas 168 and 169 that are selectable by switch 161 in response to control signal 165. In an embodiment of the present invention, the antenna 168 is an omnidirectional or substantially omnidirectional antenna and antenna 169 has a radiation pattern that includes a null, as described in conjunction with FIGS. 7-8. RF signals 167 are sent or received by the particular antenna 168 or 169 that is selected. The control signal 165 can be generated by processor 141 or application data from a location application of handheld wireless communication device 110. In operation, control signal 165 is generated to select antenna 168 for standard operation. In this fashion, when the adjunct device 100 sends paging signals 112 or receives paging signal 16, signals can be received from all directions. When the adjunct device 100 is receiving location signals 114 from a remote wireless device 120, control signal 165 is generated to switch antenna 148 to antenna 169. In this fashion the null pattern of antenna 169 can be used by the location application of handheld wireless communication device 110 to provide directional feedback to the user. FIG. 10 presents a schematic block diagram of an antenna 148′ in accordance with an embodiment of the present invention. In particular, antenna 148 is implemented via a programmable antenna 148′ that has a controllable radiation pattern. In one mode of operation, the programmable antenna is controlled via control signal 163 to an omnidirectional or substantially omnidirectional antenna pattern. The control signal 163 can be generated by processor 141 or application data from a location application of handheld wireless communication device 110. This mode of operation is selected when the adjunct device 100 sends paging signals 112 or receives paging signal 16. In this fashion, signals can be received from all directions. When the adjunct device is receiving location signals 114 from a remote wireless device 120, control signal 163 is generated to switch antenna 148′ to an antenna pattern, such as antenna pattern 160, and optionally to steer the null direction in conjunction with a directional sweep. In this mode of operation, the null pattern of antenna 148′ can be used by the location application of handheld wireless communication device 110 to provide directional feedback to the user. FIG. 11 presents a schematic block diagram of an antenna 148″ in accordance with an embodiment of the present invention. In particular, antenna 148″ is a programmable antenna that includes two separate antenna elements 176 and 174. The antenna 148″ is configurable to a first configuration where switch 161 decouples antenna element 174 and only antenna element 176 is active. In a second configuration, switch 161 coupled antenna element 174 to antenna element 176 and both elements are active. In an embodiment of the present invention, antenna elements 174 and 176 are separate loops, monopoles, dipoles or other antenna elements. The antenna formed by only antenna element 176 produces an omnidirectional or substantially omnidirectional antenna pattern. The antenna formed by the combined antenna with antenna elements 174 and 176 has a radiation pattern that includes a null. Antenna 148″ can be operated in response to control signals 165 in a similar fashion to the antenna 148 of FIG. 9. In operation, control signal 165 is generated to select the omnidirectional antenna configuration for standard operation. In this fashion, when the adjunct device 100 sends paging signals 112 or receives paging signal 16, signals can be received from all directions. When the adjunct device is receiving location signals 114 from a remote wireless device 120, control signal 165 is generated to switch antenna 148″ to the second configuration. In this fashion the null pattern of antenna 148″ can be used by the location application of handheld wireless communication device 110 to provide directional feedback to the user. FIG. 12 presents a graphical representation of a signal magnitude in accordance with an embodiment of the present invention. In particular, signal strength M represents signal strength data collected by short-range wireless transceiver 140 in response to location signal 114. As discussed in conjunction with FIGS. 7-11, an antenna having a null direction is used in this mode of operation of adjunct 100. Signal strength M is generated over a range of directions, such as over 360 degrees of rotation, either by manually steering the handheld wireless communication device 110 coupled to adjunct 100 in the case of a fixed antenna such as antenna 148 or 148″, or by steering the beam of the antenna in an implementation of a programmable antenna, such as antenna 148′. In either case the direction to the wireless device 120 can be determined based on the direction θ1, where the antenna null is pointed at the wireless device 120. As shown, the null in the antenna pattern causes the signal strength data to dip in a recognizable way. In an embodiment of the present invention, the direction θ1 is determined based on the direction of lowest signal magnitude M. However other methodologies including pattern recognition can be employed to analyze the characteristics of the signal strength data to recognize the null direction. FIG. 13 presents a schematic block diagram representation of adjunct device 100′ in accordance with an embodiment of the present invention. In particular, a further embodiment of adjunct device 100 is shown that includes many common elements of the embodiment of FIG. 5 that are referred to by common reference numerals. In addition, adjunct device 100′ includes a second short-range wireless transceiver 140′ and a second antenna 169. In this embodiment, the antenna 168 is an omnidirectional or substantially omnidirectional antenna and antenna 169′ has either a fixed or steerable radiation pattern that includes a null, as described in conjunction with antennas 148, 148′, 148″ or 169. In operation, when the adjunct device 100 sends paging signals 112 or receives paging signal 16, short-range wireless transceiver 140 is used and signals can be received from all directions. When the adjunct device is receiving location signals 114 from a remote wireless device 120, short-range wireless transceivers 140 and 140′ are both engaged and generate separate signal strength data. A difference between the signal strength data corresponding to antennas 168 and 148′ is used to determine the null direction. In this fashion, the difference between the signal strength data from the two signal paths can be used to distinguish between high loss conditions and a direction corresponding to a null. FIG. 14 presents a graphical representation of a difference signal in accordance with an embodiment of the present invention. In particular, signal strength D(θ) represents the difference between the magnitude of the signal strength data collected by short-range wireless transceivers 140 and 140′ in response to location signal 114. Representing the signal strength generated by the short-range wireless transceiver 140 as SSo(θ), and the signal strength of the short-range wireless transceiver 140 as SSn(θ), the difference D(θ), can be determined based on: D(θ)=|SSo(θ)|−|SSn(θ)| As discussed in conjunction with FIGS. 7-13, signal strength difference D(θ) is generated over a range of directions, such as over 360 degrees of rotation, either by manually steering the handheld wireless communication device 110 coupled to adjunct 100 in the case of a fixed antenna, or by steering the null of the antenna in an implementation of a programmable antenna. In either case the direction to the wireless device 120 can be determined based on the direction θ1, where the antenna null is pointed at the wireless device 120. As shown, the null in the antenna pattern causes the difference in signal strength data to increase in a recognizable way. In an embodiment of the present invention, the direction θ1 is determined based on the direction of highest signal magnitude D(θ). However other methodologies including pattern recognition can be employed to analyze the characteristics of the signal strength data to recognize the null direction. FIG. 15 presents a pictorial representation of handheld wireless communication device 110 and adjunct device 100 in accordance with an embodiment of the present invention. In particular, a display screen is shown that includes an indication of direction 166′ that can be used in conjunction with the location application examples discussed in association with FIG. 7-14. In this particular embodiment, the indication of direction 166′ moves based on the repeated directional sweeps by a steerable antenna such as antenna 148′. Indication of direction 166′ indicates, for instance, the direction θ1 as previously discussed. As the user changes the orientation of the handheld wireless communication device 110, indication of direction 166′ varies based on the updated direction θ1. The indication of direction 166′ can be used in this fashion to point the user in the direction of the wireless device 120. It should be noted that while the embodiment of FIGS. 7-15 have discussed the use of one or more antennas with a null, an antenna with a single lobe pattern or a steerable lobe pattern could be employed in a similar fashion to detect signal peaks instead of signal nulls. In yet another embodiment of the present invention, a single antenna 148 is employed that has an omnidirectional pattern at one frequency or range of frequencies, yet exhibits a null at another frequency or range of frequencies. In particular, a location signal, such as location signal 114, can be sent at frequency corresponding to the null pattern and received by short range wireless transceiver 140. Instead of switching antennas 168 and 169, or programming an antenna 148′ to different patterns as described in conjunction with FIGS. 9-11, two different patterns can be implemented in the same antenna to support both omnidirectional and null modes of operation. In a further embodiment of the present invention, a receive antenna is employed that includes a plurality of null directions at different compass points in two dimensions that are realized at different frequencies. For example, an antenna, such as antenna 148 can exhibit a plurality of null directions θi, that each have a corresponding null frequency ƒi. In particular, a location signal, such as location signal 114, can include a swept frequency chirp that begins at a low frequency and ends at a high frequency that includes each of the discrete frequencies ƒi. The short range wireless transceiver 140 can determine the direction to the remote device by detecting the frequency ƒi where the null occurs, for example based on a lowest signal level, and correlating the null frequency, via a lookup table or other data structure, to the corresponding direction θi. While the foregoing description has focused on location in a two dimensional sense, three-dimensional location can be accomplished in a similar fashion. In particular, directional antennas can be employed in both the x-y and x-z or y-z planes to distinguish z-axis, as well as x and y axis, coordinates. It should be noted that multiple directional antennas can be employed that are arranged orthogonally or non-orthogonally as long as the null directions span either all or substantially all of three dimensional space or a portion of three dimensional space that is of interest. Further more complex antenna designs with three-dimensional antenna patterns can likewise be employed in a similar fashion to determine directionality in three-dimensions. Three dimensional location can be useful, for example, in locating objects on different floors of a building or other structure such as a mine or a ship, determining of a person with a remote device has fallen overboard, as well as other three-dimensional applications. In addition or alternative to providing three dimensional direction finding, multiple antennas can be employed in a diversity receiver that, for example includes two or more receivers. Such configurations can be employed to mitigate the effects of fading, multipath interference and other path losses to provide more stable reception of signals, and more stable measurement of signal strength, round trip signal delay, etc. FIG. 16 presents a schematic block diagram of wireless devices 70 and 72 in accordance with an embodiment of the present invention. In particular, the devices 70 and 72 can each be either a wireless device 120 or an adjunct device 100. The two devices can be sold as a set and are pre-paired to communicate with one another. In another embodiment of the present invention, the user can configure the devices 70 and 72 to be paired with one another. In pairing, one or both devices 70 and 72 initiate the pairing procedure. For example, a user interface, such as user interface 132 or 142 generates a pairing signal in response to an indication from a user to pair the devices. A short-range wireless transceiver, such as short-range wireless transceiver 130 or 140, communicates RF signals, such as pairing signals 116 to pair the devices 70 and 72. While two devices 70 and 72 are shown, three or more devices can be paired together in this fashion to form a paging network. In one mode of operation, paging signals, such as paging signals 16 or 112 sent by a single device are received by all other devices and cause each of the receiving devices to generate a detectable alert signal. In another mode of operation, paging signals 16 or 112 can be generated that are addressed to a particular unit, based on addresses or other identifiers received from or assigned to, each device during the pairing procedure. For example, each device 70, 72, . . . includes a unique device identifier that is shared with other devices during the pairing procedure. Paging signals, such as paging signals 16 or 112 can include the unique identifier to direct a paging signal to a particular device. In other words, when a device 70 or 72, receives a paging signal, it extracts the device identifier from the signal and compares it to its own device identifier stored in memory. If they match, the device emits a detectable alert. If the identifiers do not match, the page is presumed to be directed to another device and no alert is generated. In an embodiment of the present invention, the paging signals 16 and/or 112 can further contain an identifier of the device that initiated the page. In this fashion, a device that receives a page and that is paired with multiple devices can determine which other device initiated the paging signal 16 or 112. In an embodiment of the present invention, the paging signals 16 and/or 112 can also contain an paging data such as text, a text message, voice, graphics or other data that is conveyed from the device 70, 72 . . . that initiated the paging signal 16 or 112 and the device to the device that receives the page. This functionality creates the possibility of wireless device 120 and adjunct device 100 being used for applications, other than simply location of a lost object. FIG. 17 presents a schematic block diagram of paging networks 90 and 92 in accordance with an embodiment of the present invention. In particular, paging network 90 includes devices 80-83 that have been paired together. In addition, paging network 92 includes devices 83-85 that have been paired together. The devices 80-85 can each be either a wireless device 120 or an adjunct device 100. As shown, device 83 has been paired with devices from both paging networks. In a broadcast mode of operation, paging signals, such as paging signals 16 or 112 sent by a single device, are received by all other devices in a network and cause each of the receiving devices to generate a detectable alert signal. In this fashion, devices 80-83 can each page all of the remaining devices in paging network 90. Devices 83-85 can each page all of the remaining devices in paging network 92. In an unicast mode of operation, paging signals 16 or 112 can be generated that are addressed to a particular unit, based on addresses or other identifiers received from or assigned to, each device during the pairing procedure. In this fashion, devices 80-83 can each page one of the remaining devices in paging network 90. Devices 83-85 can each page one of the remaining devices in paging network 92. As discussed above, device 83 resides in both networks. Consequently, device 83 can be paged by a device from either network or can page devices from either network. However, in this configuration, device 80 from paging network 90 cannot page device 85 from paging network 92, and vice versa. In an embodiment of the present invention, a device wishing to interact with another device repeatedly transmits a paging signal 16 or 112 for an interval of time greater than a listening device's wake-up-and-listen period. Say for example, a device wakes up every two seconds to “listen,” the issuing device can transmit a paging signal 16 or 112 for three seconds. This strategy has obvious power consumption advantages. While a paging application is discussed above, other applications, such as device tracking, can be enabled by the formation of paging networks 90 and 92 described above. Tracking can be implemented slightly differently. On wake-up, say every two seconds, a device transmits “tracking” information one time, then goes into listen mode to see if a paging signal 16 or 112 has been issued. The additional power consumption for the short transmit is nominal, as most of the power is consumed in the wake-up cycle itself. A device that “cares” to listen for location information can be placed into a state of listening for an extended time, say 3 seconds in our example, but it might do this only every 30 seconds, so this power hungry operation is not repeated very often. This tracking mode of operation allows a listening device to transmit useful information to any device that might care to take the time to listen periodically or on demand. In accordance with this example, a particular device 83 can be configured to track all other devices in the networks 90 and/or 92 in near real-time. The device 83 simply listens at appropriate intervals, as
