1. General

CDMA 1x is the first phase of cdma 2000 (data rate higher than IS-95, but lower than 2Mbit/s). It runs IP protocol over packet data transmission network and supports up to 308kibit/s data. It is new type of service developed from CDMA IS-95 network to provide packet data service for CDMA subscriber.

CDMA 1x is a kind of SR1 spread spectrum system. It is compatible with IS-95(A/B). Operators can easy to upgrade the network from IS-95 to CDMA 1x system to save their investment and maintenance cost.

Maximum CDMA 1x data transmission rate is 300Kb/s and actual operate data rate is about 100Kb/s (symmetric transmission). Provided TCP/IP protocol connections on this channel, CDMA 1x network can be applied on Internet connection and data transmission, etc..

The H6800 CDMA 1x modem developed by Shenzhen Hongdian Technologies Co., Ltd. provides mobile users an access to Internet and can be connected directly to personal PC via USB interface. Co-working with our dialup software, the modem can automatically detect link status and redial if the link disconnects. It is a highly reliable link satisfying requirements of industrial data transmission.
