Featured on the Research In Motion (RIM) stand at this week's 3GSM World Congress is Alpha Micro's new AMC1802GSXLA dual band GPRS1/GSM2 embedded radio modem module.
Measuring just 90 x 56mm, this highly compact modem module supports both the existing GSM radio standard and the new GPRS 'always on' radio connection.
Unlike a GSM connection, which is billed on a cost-per-second basis, GPRS is charged on the basis of cost-per-byte transferred.
Once a GPRS connection has been established with the service provider's host, the module may remain online at no cost to the user, ready to receive or transmit data.
By running TCP/IP and PPP on board, the AMC1802GSXLA radio module may be interrogated simply as an Internet address from any web browser.
Features include voice support and front-end sensitivity of 108dBm typical.
PPP, IP, TCP, PAP, and CHAP protocols are supported over the GPRS network in addition to modem emulation up to V.32 over GSM.
The module runs from a single 5V supply and drives a 5V serial interface with baud rate selectable up to 115,200bit/s.
The radio SIM module may be sited either on the user's motherboard or on the AMC1802GSXLA module itself.
Control of the modem is via a standard AT command-driven serial interface with extended register settings for the GPRS option.
In this way, the AMC1802GSXLA may be seen as a simple dial-up analogue modem to any existing user application.
Variants of this module incorporating GPS (Global Positioning System) capabilities and 12V power source are currently under development for asset management and vehicle tracking systems.
