GF-3000W CDMA Modem
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 GF-3000W CDMA 1x modem developed by Beijing Garefowl New-tech Co., Ltd. It provides mobile users to access to Internet and can be connected directly to personal PC via serial port interface. Co-working with Microsoft dialup software, this modem can automatically detect link status and redial to recover the connection if the link disconnect. It is a highly reliable link satisfying requirements of industrial data transmission.
Note: The accessories, Including AC adapter, RS232 cable and CDMA antenna will be required, along with a CDMA UIM card to operate and use the unit.
