Introduction
GSM long distance telemetry opens up a complete new area of wireless networking. Especially because GSM networks cover almost each country in the world. New
applications arise from this technology and include remotely monitoring and controlling of industrial devices, vehicles, or just communicating with a server or control room.
With the latest technology, the GPRS, the speed of data transfer is increased significantly, while decreasing the log-in and log-on costs.
By combining GPRS/GSM with a GPS device and an on-board processor, stand-alone applications, like AVL (Automatic Vehicle Location), can be easy, quickly,
and low-cost realized.
The M100 series tri-band modems support the three main GSM frequencies (GSM-900, DCS-1800, and PCS-1900) for use in Europe,
Asia-Pacific (except Japan), parts of USA, Canada and South America.
General Specification
- Fixed baud rate configurable to match terminal equipment speed.

- Configurable host IP address and port number (GPRS only).
- Auto connect on DTR or by AT command.
- Data transfer by UDP for minimum latency and data overhead.
- Auto reconnect after connection drop.
- Host end (ON/OFF) control of auto forwarding
- Optional auto identify header for units with dynamic IP (GPRS only)
- All settings non-volatile
- Type approved by ETSI (European Telecommunications Standards Institute)

Three types of modems are available at WMCS:
M100 GPRS-GSM Triband Modem
|
A standard GPRS Triband Modem for fast data transfer in the GSM networks over the serial port. The GPRS modem is used at a remote location to set up a
virtual connection between a remote device (with a serial port) and a central computer. Typical applications include Telemetry, Security Systems, Data Loggers, or any remote
equipment with serial data port. Applications include Telemetry Market,
Automotive GSM Module, Hand Held Terminals, EPOS, Wireless Terminals, Monitoring/Safety, Point Of Sales.

M110 Stand Alone TCP - UDP/IP
embedded GPRS-GSM-GPS-I/O Triband Modem
|
This compact and complete GPRS modem also includes an integrated GPS module and an on-board processor.
Five I/O pins can be used to control or monitor external
events. This configuration serves any stand-alone applications where fast data transfer, global positioning, and event control is needed. Applications include Telemetry Market,
Automotive GSM Module, Hand Held Terminals, EPOS, Wireless Terminals, Monitoring/Safety, Point Of Sales.
