Part B – M Series Overview
Definition of M Series Data Radio
The M Series is a range of wireless modems designed for the
transmission of data communications for SCADA, telemetry and any
other information and control applications that utilise ASCII messaging
techniques. The M Series uses advanced “digital” modulation and
signal processing techniques to achieve exceptionally high data
throughput efficiency using traditional licensed narrow band radio
channels.
These products are available in many frequency band and regulatory
formats, to suit spectrum bandplans in various continental regions. The
range is designed for both fixed point to point (PTP), and multiple
address (MAS) or point to multipoint (PMP) systems.
M Series Product Range
The M Series range consists of the a half duplex “Remote” radio
modem and provision to use an E Series Base Station, including an
optional Hot Standby controller to control two base station units in a
redundant configuration.
Frequency band variants are indicated by the band prefix and model
numbering. (See Model Number Codes)
