WEBCDMA2000 1xEV-DO (Evolution-Data Optimized), often abbreviated as EV-DO or EV, is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access.
Code-division multiple access - Wikipedia
WEBCode-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access , where several transmitters can send information simultaneously over a single communication channel.
WEBThe 3X stan-dard has now been superseded by a two-phase strategy called CDMA2000 1xEV, where 1xEV stands for 1X evolution, or evo-lution using 1.25 MHz. TodayÕs CDMA2000 1X systems are based on a stan-dard 1.25 MHz carrier for delivering high data rates and increased voice capacity (Figure 1).
CDMA spectral efficiency - Wikipedia
WEBCDMA spectral efficiency refers to the system spectral efficiency in bit/s/Hz/site or Erlang/MHz/site that can be achieved in a certain CDMA based wireless communication system.
