SocketModem® GPRS

Wireless Standards Supported: GPRS Class 10

Compatible Operating Systems: Operating system independent

The SocketModem® GPRS embedded wireless modem is a complete, ready-to-integrate module
that offers standards-based multi-band GSM/GPRS Class 10 performance. The SocketModem GPRS
is based on industry-standard open interfaces and utilizes Multi-Tech’s universal socket

It integrates the controller, RF transceiver, antenna interface and SIM socket in one
module. This integration
requires low power, low real estate and provides an overall reduction in costs. It
provides faster time-to-market because it relieves the burden and expense of obtaining
PTCRB and RF approvals. Also includes an embedded TCP/IP protocol stack.

This modem interfaces easily with existing products through a standard serial
communication channel. The serial DTE channel is capable of transfer speeds to 115.2K bps
and can be interfaced directly to a UART or microcontroller. The on-board RF transceiver
interfaces with an antenna for direct connection to wireless SMS, circuit-switched
dial-up, or packet data networks. Also includes an onboard LED to display network status.

Multi-Tech’s Universal socket flexible com-port architecture
provides cellular, Ethernet, PSTN or Wi-Fi® network access with interchangeable

Developer’s Kit – allows you to plug in the module and use it for testing, programming and
evaluation. The kit includes one development board with RS-232 DB-25 connector, universal
power supply, antenna and RS-232 cable.
