Transportable : LAST MILE VHF COMMUNICATION OVER 3G/4G CLOUD

Control rooms can be equipped with Audio Over IP interface Gateway through which remote non LOS VHF/UHF radio communication from incident sites can reach the Control Room through the mobile gateway with Inbuilt 3G/4G Router connected with VHF/UHF radio in vehicles. Thus VHF/UHF radios can be made to work over the Internet 3G/4G cloud.
The Gateway integrates one radio/audio port, a VoIP Gateway, Client Server, Communication switch a Call Manager and 3G/4G SIM Router into a single compact, light weight and low power system. It runs on Linux environment and provide seamless interface between radios using open standards Voice over IP technology.
It would require 1 pair of IP Gateways to transfer VHF Radio communication from the incident site to the Control room. 1 IP Gateway will be interconnected to the VHF Radio in the vehicle through Audio in/out & PTT/COS signals. At the Control room there would be an audio console equipped with built in Speaker gooseneck Microphone and PTT switch connected to another IP Gateway.

Operators at control room could then talk to the Walky Talkies at incident site through the Audio console. Similarly the personnel at site around the vehicle can communicate with the control room using their walkie talkies. This communication from site to control room is not dependent on distance and VHF communication range related issues between control room and site. This could also be very useful for enclosed space communication where personnel cannot communicate to control room directly due to LOS issues .
 
The Transportable version is also available where the Roip is installed in a transportable kit with the VHF radio inbuilt with necessary interfacing & cabling for ease of use. It has its internal Ac /DC convertor and can operate through Ac or DC source. Comes with inbuilt GSM antenna and connectors to connect external VHF antenna.
