... The M48A is a 4800 baud radio modem, compatible with narrowband radios. Just a faster i1200 simpler RPM1 ? ....... not quite. What does an M48A the simplest possible sense, the M48A is just a radio modem baseband device. It provides an interface between a user's asynchronous (“RS232 type”) serial port and the audio channel of a low power radio module. ...

... On transmit, a different burst identifier is attached to each new packet. The receiving unit ignores the second (and subsequent) packet with the same identifier. This allows a receiving M48 to ignore multiple copies of the same data packet (as will be encountered in multiple transmission or repeater/network systems) Radiometrix Ltd M48A Modem Data Sheet page 6 ...

... This is especially useful for the master node in point to multi-point operation. Timings The data throughput of the M48A is limited by the radio path. In continuously streaming (transparent) mode a baud rate of 4800 baud is supported without any buffer overflows. Byte latency is influenced by the switching performance of the radio (and the programmed DELAY and PREAM values) ...
