GF-3000W CDMAModem
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 spectrumsystem. It is compatible with IS-95(A/B). Operators can easy toupgrade the network from IS-95 to CDMA 1x system to save theirinvestment and maintenance cost.
Maximum CDMA 1x data transmission rateis 300Kb/s and actual operate data rate is about 100Kb/s (symmetrictransmission). Provided TCP/IP protocol connections on thischannel, CDMA 1x network can be applied on Internet connection anddata transmission, etc...
The GF-3000W CDMA 1x modem developed byBeijing Garefowl New-tech Co., Ltd. It provides mobile users toaccess to Internet and can be connected directly to personal PC viaserial port interface. Co-working with Microsoft dialup software,this modem can automatically detect link status and redial torecover the connection if the link disconnect. It is a highlyreliable link satisfying requirements of industrial datatransmission.
Note: The accessories, Including ACadapter, RS232 cable and CDMA antenna will be required, along witha CDMA UIM card to operate and use the unit.
