Cermetek Microelectronics, Inc. today introduced the CH2168, an external, Internet enabled, GPRS/GSM wireless modem :
CH2168 RF Cellular Solution with RS232 Interface for Remote Monitoring Via the Internet .

Cermetek Microelectronics, Inc. today introduced the CH2168, an external, Internet enabled, GPRS/GSM wireless modem. The CH2168 provides TCP/IP cellular radio communications for autonomous or semi-autonomous M2M applications.

CH2168 an external Internet enabled GPRS/GSM wireless modem The CH2168 GSM/GPRS cellular radio is pre-approved on the AT&T and T-Mobile networks in the United States and GCF approval for the European Union. Typical applications for the GPRS/GSM external wireless modem include remote data transmission/reception systems, such as those found in the chemical production and bulk transportation industries, energy production market segment, and scientific research where robust, reliable communication is a must.

The CH2168 is housed in a rugged aluminum enclosure and comes complete with numerous Industry Standard interfaces, including: TCP/IP stack, Linus OS, BSD socket API and all necessary protocols to conduct multiple and simultaneous Internet operations.

The CH2168 delivers a convenient, reliable wireless data solution for remote systems. The CH2168 can be controlled by an external host via an RS232 serial interface or can run C, C++ or C# user applications on the onboard Coldfire processor. By hosting the user application, the CH2168 allows the system to employ a less powerful host controller or even eliminate the need for an external host controller. The RS232 serial interface simplifies integration of the CH2168 into existing systems. Operation can be controlled by issuing simple, intuitive commands through the serial interface. Two Watts of output power insure reliable communications even in remote locations.

"The CH2168 provides the remote system operator with reliable, low cost internet access without the time delay or expense of installation and maintenance of PSTN telephone or Ethernet cabling" said Cermetek President Henry Roskos. "Additionally, the CH2168 provides ongoing cost savings by allowing data to be moved across the Internet without incurring long distance telephone charges."

The CH2168 is the first in a family of GPRS/GSM modems planned for introduction by Cermetek incorporating a multi-network approved GPRS/GSM quad band radio and Coldfire processor. The internal 2 Watt GPRS/GSM radio handles encoding, transmission, and reception of the data signal. The Coldfire processor runs the TCP/IP stack, manages the data stream, executes both system and user supplied API, and monitors/controls the data/Internet link(s). When required by the user application, operation of CH2168 can be controlled by the user by issuing simple intuitive commands to the CH2168 via its RS232 interface. Unit cost is under $350 each in 250 piece quantities and is available for immediate delivery.

Update February 6, 2009:,
The editors of eg3.com recently selected the CH2168 GPRS/GSM modem to receive their "Tech Choice" award.
