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.
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.
EDGE stands for Enhanced Data Rate for GSM Evolution, it is capable of offering data rates of 384 kbps and, theoretically, of up to 473.6 kbps. A new modulation technique and error-tolerant transmission methods, combined with improved link adaptation mechanisms, make these EGPRS rates possible. This is the key to increased spectrum efficiency and enhanced applications, such as wireless Internet access, e-mail and file transfers.
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.
Galaxy family 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.

Since
the GALAXY H7921 VPN router supports PPTP, L2TP+IPSec VPN features. Customer
can easily set up their own private network by using GPRS/EDGE/CDMA 1x
network. With the built-in IPSec encryption function, it also provides
a high security channel and protects the user data transmission. Below
diagram is the typical VPN application.
For
industrial applications, it requires a device to collect information from
discrete remote sites. The application show as below diagram is a typical
video surveillance configuration. You can connect GALAXY router to a net-camera,
and then setup the Data Service Center (DSC) IP address or domain name
at Galaxy router.
Galaxy router can be
configured as following network applications.
Ethernet/Mobile network routing.
Serial port/Ethernet converter.
Serial port/Mobile network transmission.
Ethernet/Mobile network routing
By connecting your LAN and mobile network (WAN), you can share the GPRS
or CDMA 1x access to your LAN by built-in NAT (Network Address Translation)
technologies. Therefore, multiple IP terminals or PCs can share the Internet
access via Galaxy router.
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.
