SRG3500 Mobile Gateway
When it comes to advanced mobile radio communications, the
SRG3500 is hard to beat. This top-of the line radio comes with
built-in gateway and repeater functionality. In gateway mode it
forms a bridge between the trunked TETRA network and a number of
individual hand-helds, giving improved access to the network in
areas of poor reception. In repeater mode it acts as a powerful
mobile base station for a number of hand-helds in the field, which
are operating separately from the TETRA network.
A range of accessories enables the SRG3500 to be mounted in a
car or emergency vehicle, on a motorcycle, in a covert vehicle or
marine vehicle.
The SRG3500 can be fitted with a GPS module to enable advanced
location-based functionality.

DMO Repeater
Achieve greater range with the Sepura DMO
Repeater functionality. This feature enables a Sepura terminal to
'repeat' received voice and data calls giving greater effective
range to the participating terminals. Uniquely available on
handheld, covert and gateway radios this licensed feature can be
enabled whenever necessary using Radio Manager.
