Wireless modem module gains GPS
functionality
Alpha Micro's AMC1802GSXLA dual-band GPRS/GSM embedded radio modem module is now available with optional GPS (Global Positioning System) functionality.
Alpha Micro's AMC1802GSXLA dual-band GPRS/GSM embedded radio modem module is now available with optional GPS (Global Positioning System) functionality Developed using the RIM 1802G and RIM 1902G OEM radio modems for GSM/GPRS wireless networks, the module is ideally suited for telemetry, asset management and vehicle tracking applications, and for transmitting data to and from wireless mobile electronic devices such as point-of-sale terminals or metering equipment

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.
Dual-band module has wireless standards covered
New from Alpha Micro Components, the AMC1802GSXLA is a dual-band GPRS/GSM embedded radio modem module.
Key areas set to benefit from the new modem include Eastern European countries, who have an excellent GSM network but poor telephone infrastructure, and the USA, where the modem's ability to receive GPS information will prove extremely useful when current products based on the analogue AMPS (Advanced Mobile Phone Service) radio system are replaced in the next two years by GPRS-based solutions.
Measuring just 90 x 56mm, Alpha Micro's 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 extra 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 -107dBm 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 5 or 12V 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.
The AMC1802GSXLA will be featured on Research In Motion's stand at CeBIT 2003 in Hanover in March.
