Chennai, India: The Tamil Nadu state police in India will soon get a digital wireless network system for better communication within the force. This announcement was made during the budget session for the home, prohibition and excise departments in the state assembly. The system will use Terrestrial Trunked Radio (TETRA), a professional mobile radio and two-way transceiver specification designed for use by government agencies, emergency services (police, fire and ambulance services), public safety networks, transport services and the military.
TETRA radios in the patrol vehicles are equipped with integrated GPS module and data from these GPS modules are sent to the control room through a short data service at preconfigured intervals.
Speaking to TOI, Inspector-General of Police (Tirunelveli ) Karuna Sagar said, “It helped us track those hanging up on those in the control room after calling ‘100’. Patrol teams can be directed to the nearest GPS-fitted vehicle to reach a place and resolve the problem in an emergency. A real-time monitor helps police check the movement of patrol vehicles.”
In Salem and Tirunelveli, the GPS data of patrol vehicles were plotted on a digital map helping police officers with the required security clearance view the vehicles’ position. When a police officer receives a call from a member of the public, the location of the caller along with the position of the nearest patrol vehicle shows up on a computer screen allowing the officer to direct the patrol vehicle to the said site.
