“The digital radio system is more secure compared to the existing VHF. Moreover, DMR and DPMR systems come with several advanced features giving a technical edge for policing activities. The DMR is very secure as its frequency is very high."

After the initial delay, the decision to provide Digital Mobile Radio (DMR) and Digital Private Mobile Radio (DPMR) for the police in Kochi and Thiruvananthapuram (India)  cities is gaining momentum. The Police Department has decided to renew the proposal to purchase DMR and DPMR to replace very high frequency (VHF) system.

 

There were reports that some Chinese commercial radio sets available in the market could be tuned to police frequency and information easily leaked through wireless sets. Considering the loopholes in the VHF wireless sets, the usage of digital communication system would offer a major relief for the Department.

 

Though the Department had decided to induct DMR and DPMR in January it was stalled due to paucity of funds. As the Home Department has allotted more funds it has been decided to purchase the new sets soon.

 

“The digital radio system is more secure compared to the existing VHF. Moreover, DMR and DPMR systems come with several advanced features giving a technical edge for policing activities. The DMR is very secure as its frequency is very high. The VHF system functions in the frequency of 136 to 176 MHz whereas the DMR and DPMR signals are tuned at the frequency of 400 MHz to 470 MHz. Besides, it can cover the entire city limit without any outdoor or indoor disturbances wherever deployed,” an official with the police telecommunication department said.

 

The DMR and DPMR systems are also 3G-enabled and have full band signals. The handsets of the system support more than 256 channels. The new system contains repeaters, aerial mast, lighting arrestors, mobile/static transreceiver sets, hand-held transreceiver antennae and display system.

 

 The police are planning to purchase 16 repeaters, 200 mobile/static transreceiver sets in which 80 will be Global Positioning System(GPS)-enabled sets and 120 non-GPS. Of the 400 hand-held transreceiver sets, 100 would be GPS-enabled.

“A fund of `6 crore has been allotted for the purpose.
