1.1 General
2.5G mobile communication technology (GPRS/EDGE/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/EDGE 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, Hongdian co-operates
with mobile service providers to design products and network configurations
suitable to industrial end users’ individualized applications. Hongdian has
developed embedded, advanced and reliable Galaxy mobile (GPRS/EDGE/CDMA
1x) router for the applications.
Galaxy H7920 Mobile Router User Manual Chapter 1: Introduction
GPRS 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/EDGE network, CDMA 1x network can provide a maximum
bandwidth up to 300Kb/s and actual transmitting and receiving bandwidth
reaches 100Kb/s.
Typical center to multipoint system configuration plan is as below.

Application 4: Mobile Network/PSTN backup
Galaxy H7920 can be connected to mobile network, PSTN dialup network and
Ethernet, those channels can be backup each other with the built-up backup
function.
Bellow diagram is a typical solution for finance application. At the normal
situation, the transaction data generated by POS or ATM will be transmitted via
GPRS/EDGE or CDMA 1X network. When the mobile network failed, Galaxy
router will dial the modem connected at its COM port, and then route the data via
the dial-up channel. It is a very useful solution for finance application and other
applications that requires high availability.
Serial port/Ethernet converter
For many non IP traditional terminals, you can also connect your non IP
terminals to Galaxy router via RS232/485 interface. After then, your non IP
terminal will become standard TCP/IP 10/100BaseT interface network
equipment. It is possible to connect many non IP terminals to IP network at
same place.
