Vehicular Tactical Network
The Vehicular Tactical Network (VTac-803) is an 800
MHz software-based digital mobile network repeater
for extending network coverage to portable radios,
providing scene-of-incident capability and the full
feature set of an M-803 mobile radio.

VTac supports the OpenSky communication protocol
in the 800 MHz SMR and NPSPAC frequency bands
with a high performance data modem that gateways
both voice and data to the OpenSky wide area wireless
data network.

More capable than a stand-alone M-803, the VTac-803
is a hybrid product that combines several hardware
components into a multi-use communications device to
extend the capabilities of a movable Base Station
wherever you position your vehicle.

Backward and Forward Compatibility
The software-based architecture allows the VTac-803
to be programmed for a variety of modulation
techniques, providing legacy support and guarding
against obsolescence.

Over-the-Air Programmability
For agencies engaged in an analog-to-digital transition,
The VTac-803 can function with existing analog
infrastructure today and, when the time is right, receive
over-the-air field reprogramming for a virtually
seamless transition to fully digital communications
without replacing equipment.
