ice traffic and broadband mobile multimedia (speech, audio, text, graphics, and video) services. There are three main 3G services, including WCDMA, CDMA2000, and UMTS TDD. See also 3GPP and 3GPP2. 3GPP (3rd Generation Partnership Program) A collaborative group that is developing an agreement to jointly create technical specifications for maintaining LTE, GSM, GPRS, and EDGE and for evolving WCDMA and LTE networks. European, Asian, and North American telecommunications standards bodies formed the 3GPP. 3GPP2 (3rd Generation Partnership Program 2) An analogous group to 3GPP, but it is working on evolving technical specifications for CDMA2000 networks. 10base-T An IEEE specification for unshielded, twisted-pair cabling used for Ethernet LANs that transmit at 10Mbps. The distance limitation for 10base-T networks is 100 meters. 100base-T An IEEE standard compatible with 10base-T for transmitting at 100Mbps over unshielded twisted-pair cabling on LANs. www.TechnicalPDF.com 802.11 A set of IEEE standards for LANs. 802.11a, 802.11b, and 802.11g are the most common and are used in homes to share Internet access, in enterprises, and in hotspots. 802.15.4 The IEEE standards upon which the ZigBee Alliance tests and certifies equipment, and adds functions to sensor networks. 802.20 A set of IEEE standards for wireless technology based on OFDM. Flarion, which is part of Qualcomm, builds 802.20 equipment. 8YY toll-free numbers An abbreviation describing the format of the North American Numbering Plan for toll-free numbers. The first three digits of toll-free telephone numbers must be the number 8 followed by o or 2 through 9 for the second and third digits. When central office switches see the 8YY format, they request a database check to determine where the toll-free number should be routed. adaptive bit rate streaming The capability of equipment (encoders) used to stream video and multimedia content from the Internet to computers and mobile devices to adjust the bit rate dynamically to the user's processing capabilities and ba
