2.5G mobile communication technology (GPRS/CDMA 1x) has become widely used of industrials and utilities in recent years and many customers are seeking reliable, flexible and cost-effective data channel to build their information system. Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; This brings a bright future for GPRS and CDMA 1x data networks applications.

Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones. Hence, garefowl co-operates with mobile service providers to design products and network configurations suitable to industrial end users? ? Individualized applications. Garefowl has developed embedded, advanced and reliable GF Series (GPRS/CDMA 1x) router for the applications.

CDMA network theoretically can provide a maximum bandwidth 171.2Kbps, actually; It works at 40~100Kbps bandwidth (it depends on service provider? ? S operation policy). As we know, GPRS is packet based network which provides TCP/IP communication channel.

Same as GPRS network, CDMA 1x network can provide a maximum bandwidth up to 300Kb/s and actual transmitting and receiving bandwidth reaches 100Kb/s.

Since Garefowl has many years experience of mobile data communication, it proves that Garefowl products are widely applied and work stably.

GF Series router is a dedicated ideal data transmission channel for industrial applications. It can be operated at GPRS or CDMA 1x network by selecting a different radio module.

Features Functions

1)Non host support

Normally, GPRS or CDMA 1x Modem can be connected to a PC, and then dial an access number manually; It utilizes the PC resources to process the data transmission and protocol conversion. GF Series router is an embedded platform built-in with a processor, RTOS, protocol stack and application software. It works automatically without host PC.

2)Always online

GF Series Router will automatically attach to GPRS or CDMA 1x network

When it is powered on, and then setup a transmission channel.

3)Toll on traffic

GF Series Router can be configured to work always online; It is charged

According to traffic.

4)High speed

Maximum GPRS bandwidth can be 171.2kb/s, only 40? ? 100kb/s can be reached at actual application. Maximum CDMA 1x network bandwidth can be 300kbps. However, the bandwidth will depends the operator S policy. For example, it is only 80 100kbps bandwidth at China Unicom CDMA 1x network.

5)Routing and NAT functions

GF Series router provides routing table and NAT function; It is an ideal solution for branch office connection or SOHO application.

6)Simple and flexible to use

GF Series router is a powerful and easy to used device. It is easy to build your own private mobile data network.
