CDMA Technology Advancing, Simultaneous Voice & Data Usage Coming Soon
In a press release today by the CDMA Development Group, it was announced that the specs for CDMA2000 1X Advanced have been completed and published. Some of the technology enhancements, said to be available in 2010, will include: base transceiver station (BTS) interference cancellation, improved power control, early frame termination, and smart blanking. The improvements, in theory, are capable of quadrupling the voice capacity of existing CMDA2000 1x networks.
Also in the press release, it was stated that “a complementary device enhancement known as simultaneous 1X Voice and EV-DO Data (SVDO) will also become available during the same timeframe and will enable CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call.” This means CDMA users will finally be able to access the web, send emails, use data intensive GPS navigation options like updating maps or downloading traffic info, and more while on phone calls.
