The new brand of AMC1802GSXLA’ dual band GPRS1/GSM2 has been released by Alpha Micro Components (wvAv.alphamicro.net), which has the radio modem inside. This new product is developed with RIM’s superior radio modem, which is become ideal to transmit the data to and from wireless mobile electronic devices. These devices include point-of-scale terminals and metering equipment.

The size of this new product is 90mm x 56mm. It can be used with the GSM radio standard and the new GPRS ’always on’ radio connection. The new device is charged on the basis of cost-per-type transferred, which is very different form the GSM connection. The GSM connection is always charged on a cost-per-second basis. The module will keep online without the user’s pay when the GPRS is connected with service provider’s host. The relay is used to receive or transfer data. People can easily trace the AMC1802GSXLA radio module from any web, if they run TCP/IP and PPP on boaid.

Voice support and front end sensitivity 108 dBm are the typical features of this new device. The device will be available with the PP, IP, TCP PAR and CHAP protocols over the GPRS network unless the emulation is up to V.32.

By using the baud rate selectable which is up to 115,200 bps, a single 5Volt supply can produce the module, and the 5 volt serial interface can be driven by the module. Users can place the radio SIM module on their motherboard and on the AMC1802GSXLA module itself.

Through a standard AT command-driven serial interface with extended register settings for the GPRS option, the users can easily handle the new device. With the above method, the AMC1802GSXLA will become an easy dial-up analogue for any applications of user.

Now, developers are paying much effort in developing all kinds of module incorporating GPS (Global Positioning System) capabilities and 12 volt power source. Their applications are mainly in asset management and vehicle tracking systems.
