ZTE offers cdma2000 1x Voice Service
After replacing channel cards, ZXC10 CDMA system of ZTE offers cdma2000 1x telephony service, allowing communications among 3G and 2G mobile phones, among 3G mobile phones, and among 3G/2G mobile phones and fixed phones. This is the first CDMA system that offers cdma2000 voice in China.
Cdma2000 broad communication technology is one of the most important 3G mobile communication solutions. Cdma2000 1x, the first phase of cdma2000, supports up to 144-kbps package services, offering at least two times of capability of narrow CDMA (IS-95) system. Besides, it is compatible with the narrow CDMA.
Cdma2000 technology is promising globally. A large cdma2000 network is being built in Korea. The narrow CDMA technology was employed in north America, Korea, Hong Kong, Australia, and other countries and regions, which will be evolved to 3G one by using cdma2000 technology. China Unicom (www.chinaunicom.com) is licensed to set up a nationwide CDMA network which will be also evolved to 3G one by cdma2000 technology. Cdma2000 1x will be widely used all over the world.
The début of the broad CDMA system will increase ZTE’s competitive edges, allowing it to occupy more shares of market in mobile communication.

ZIF-NIF makes it easy to make GPRS handset for all
four frequencies, 900-1800-1900-2100Mhz!!
That is, not one line of code need to be rewritten
going from 1900 to 2100MHz, not even carrier
trackers due to slightly increased doppler effect..

When will GPRS make it into the open? CDMA2000, etc, seems to work in the open. |
