Description
The SMARTALPHA Radio Modem module provides a simple interface wireless communications module for the
transfer of data at of up to 19200bps. Its unique features of narrow band operation and user channel selection
combined with excellent interference rejection make them an ideal choice for next generation applications.
The transceivers have the functions of a complete radio modem and simply require CMOS/TTL data at the
transmit input and the corresponding transceiver(s) output the same data. Preamble and CRC are
automatically generated and added to the RF signal
Possible applications include one-to-one and multi-node wireless links in applications including car and building
security, EPOS, inventory tracking, remote industrial process monitoring and computer networking. Because of
their small size and low power requirements, both modules are ideal for use in portable, battery-powered
applications such as hand-held terminals.
