The GDMP10 is a radio modem with 10 Watts output power and well-suited for SCADA, meter reading and power grid management with wireless connections.
It operates in three frequency bands, covering 136-174MHz, 223-235MHz and 400-470MHz respectively. Hundreds of thousands of meters may be polled or report-in every day on a single radio channel.
The GDMP10 radio modem operates in transparent transfer mode, which ensures compatibility with most user systems and protocols. The radio modem can be reprogrammed to operate at any channel within its frequency bands through a configuration software.
