Basingstoke distributor TDC is aiming at video surveillance and other multimedia embedded systems with its socket modem.

From Multi-Tech Systems, the modem in integrates the controller, RF transceiver, antenna interface and SIM card holder in one type-approved communications device. 

Designed for tri-band UMTS/HSDPA as well as GSM/GPRS/EDGE, the only additions needed are an antenna, a SIM card and a power feed.

There is a choice of serial or USB2.0 interfaces, and the modem can be driven with standard AT commands.

Its serial DTE channel is capable of transfer speeds of up to 920kbit/s and can be interfaced directly to a UART or microcontroller.

As it is based on Multi-Tech’s universal socket architecture, the modems can be swapped with other interfaces offering Ethernet, Wi-Fi, PSTN, and other cellular standards. The modems are FCC, PTCRB and R&TTE certified.
