Although this allows higher maximum speeds, the average speed per user will not change significantlycdma. Mcps. Fourth generation All- IP wireless system that will probably be based on OFDM to provide downlink rates of 1. Mbps to 1 Gbps and uplink rates of 1- 1. Mbps. QAM with 6 bits per symbol. An IEEE committee that standardizes a wireless Ethernet replacement technology in the ISM band. Mbps in the 2. 4. GHz band. 8. 02. 1. Mbps in the 5 GHz band. Mbps in the same band as 8. A Wi. Fi. WLAN variant that is higher speed (5. Mbps) than 8. 02. Because it also operates in a different frequency band it has proven less popular than 8. The range of this protocol is also lower and the LOS requirements more stringent. See ADRCIEEE Wireless LAN system providing throughput of about 1. Mbps but see ADRCAn IEEE standard for network interoperability between WLAN protocols. An IEEE standard for operation of their WLAN protocols outside the normal frequency bands (e. This gave it an advantage over 8. An IEEE standard for spectrum and transmit power management for their WLAN protocols. Enhanced security for IEEEWLAN protocols. An adaptation of 8. WLAN protocols to the Japanese 4. GHz frequency band. A proposed IEEE standard for RRMA group for editorial maintenance of IEEE8. WLAN standards. A future IEEEWLAN protocol that promises raw data rates of 5. Mbps in either the 2. GHz or 5 GHz band and thus will likely eventually replace 8. The protocol is scheduled for completion in 2. See EWCA proposed IEEE standard for ITS. Also known as WAVEA proposed IEEE standard for handoff between APs. A proposed IEEE standard for mesh networking. A proposed test specification for IEEEWLAN standards. A proposed standard for authorization of users on IEEEWLANs. A proposed wireless network management standard for IEEEWLAN protocols. A proposed standard for the protection of system management information in IEEEWLAN protocols. A proposed standard for operation of IEEEWLAN protocols in the 3. GHz frequency band. See Bluetooth. IEEEWi. Max radio interface. An IEEEgroup studying MBWAIEEE standard for Ethernet. PSK with 8 states, allowing the coding of 8 bit combinations. It is used in EDGE. QAM with 3 bits per symbol. The ES service code in many parts of the United States, Canada and a few other countries. A An IP host address. Interface between BSC and MSC. Interface between BTS and BSCAssisted GPS. Network provides information to mobile device to acquire satellite signals and may assist with processing of received data. Interface between the MSC and BSThe primary CAVE authentication key, used to generate SSDAnalog/Digital. Usually used in the context of conversion from analog to digital (or vice- versa)GSM authentication algorithm. GSM data encryption algorithm. A stream cipher for the encryption of 1.

Abbreviated Dialing Numbers. Adaptive Differential PCMAggregate Data Rate Caveat. A warning that most wireless data rates are aggregate, meaning that all users share the bandwidth, and often they are raw rates higher than the actual user throughput could ever be even on an unloaded system. It is probably good to start by dividing the raw rate by a factor of two to obtain the total user throughput rate and then further divide by the average number of simultaneous users (not connected users, but the number who are likely to be simultaneously transmitting)Asynchronous Data Service.
