GD16000 is an air rate of 16000bps radio modem with 25KHz channel spacing that provides reliable, real-time data communications. The radio modem is suitable for narrow band telemetry, alarm and data transfer applications.
The radio modem works in store and forward mode and therefore any radio modem in a network can be used either as a master station or as a slave station. The radio unit can operate as a transparent radio link, and is ideal for most types of wireless serial communication, essentially replacing a wire with classic RS-232 based protocol.
