VX4700 Vehicle Device

Vehicle Device and MCX Platform for Mission Critical Users

Thorcom® VX4700 is a high performance Fixed Vehicle Device platform that provides next generation voice and data communications for Mission Critical Users including the Emergency Services and other mission-critical users on the UK Emergency Services Network (ESN).

VX4700 supports voice and data on prioritised bearers (such as ESN in the UK), including Mission-Critical PTT and data via the public Internet, or User Organisation private APNs.

VX4700 is designed to meet the harsh conditions found in the mobile environment and is suitable for standard and covert installation in a wide range of vehicles including passenger cars, rapid response vehicles, ambulances, fire appliances, commercial vehicles, motorbikes and marine vessels, and is compatible with a wide range of industry standard of optional components and accessories.

VX4700 takes the place of a ‘traditional’ radio unit and contains a high performance processor, memory, 4G/LTE cellular radio module, Wi-Fi radio module and interfaces to provide a wide range of voice and data services at multiple levels of priority. VX4700 interfaces include managed power, multiple antennas, microphones, speaker, D2D radio, CANbus, USB, Ethernet LAN and GPIO. The unit is usually installed in a location such as under a seat, in the boot, on a ‘comms board’ or in a comms cabinet.

VX4700 provides a Graphical User Interface via a standard HDMI video output/USB touch input which is compatible with any in-vehicle HDMI-compatible touchscreen device, including rugged vehicle touchscreen monitors in variable sizes, and vehicle OEM screens via a hardware HDMI switch.

VX4700 can also be supplied with a standard ‘radio console’ and/or other physical controls for power on/off, volume up/down, programmable keys for application short-cuts and a dedicated Emergency key. The keys are backlit, tactile and designed to be used while wearing gloves.
