<P>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. </P>
<P>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.</P>
<P>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.</P>
<P align=left>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.</P>
<P align=left>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.</P>
<P align=left>Since Hongdian has many years experience of mobile data communication, it proves that Hongdian products are widely applied and work stably.</P>
<P align=left>Galaxy family router is a dedicated ideal data transmission channel for industrial applications. It can be operated at GPRS/EDGE or CDMA 1x network by selecting a different radio module. </P>

<TD class=td2>1) Built-in 4-ports fast Ethernet switch</TD>
<TD class=td2 width=478>With the built-in 4-ports fast Ethernet switch, Galaxy H7930 Router supports 4-LAN+DMZ topology. It brings the convenience and benefit for SoHo users and industry applications.</TD></TR>
<TR>
<TD class=td2>2) Non host support</TD>
<TD class=td2 width=478>Normally, GPRS/EDGE 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. Galaxy H7930 router is an embedded platform built-in with a processor, RTOS, protocol stack and application software. It works automatically without host PC.</TD></TR>
<TR>
<TD class=td2>3) Always online</TD>
<TD class=td2 width=478>Galaxy H7930 Router will automatically attach to GPRS/EDGE or CDMA 1x network when it is powered on, and then set up a transmission channel.</TD></TR>

<TD class=td2>4) Toll on traffic</TD>
<TD class=td2 width=478>Galaxy Router can be configured to work always online; it is charged according to traffic.</TD></TR>
<TR>
<TD class=td2>5) High speed</TD>
<TD class=td2 width=478>Maximum GPRS bandwidth can be 171.2Kb/s, only 40~100Kb/s can be reached at actual application. EDGE is capable of offering data rates of 100~200Kb/s and, theoretically, of up to 473.6Kb/s. 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.</TD></TR>
<TR>
<TD class=td2>6) Routing and NAT functions</TD>
<TD class=td2 width=478>Galaxy H7930 router provides routing table and NAT function; it is an ideal solution for branch office connection or SOHO application.</TD></TR>
<TR>
<TD class=td2>7) Simple and flexible to use</TD>
<TD class=td2 width=478>Galaxy H7930 router is a powerful and easy to used device. It is easy to build your own private mobile data network.</TD></TR></TBODY></TABLE></TD></TR>
