In news: The Delhi Police will move to the ‘Open Standard Digital Trunking Radio System’ (OS-DTRS) and will phase out the current tetra net wireless network services.

  • The project will cost close to Rs 100 crore

About new system:

  • It is an internal communication system of Delhi Police
  • It is more efficient and aims at faster exchange of information
  • The trunking system provides multiple channels and common groups for policemen.
  • This way, they are communicating with more personnel using fewer groups, officials said.
  • Groups are formed based on geographical area and function.
  • It will also have a voice logger system, which can be used to describe a crime scene, interrogation details and evidence. The logs are saved in the system.
  • The project’s master site will be at the Delhi Police HQ.
  • Police are looking for private companies to run the system on 800 MHz frequency band and microwave links.
  • There will be a tower that can withstand wind speeds of up to 160 kmph.
  • Around 15,000 concurrent radio sets will be made first and later expanded to 30,000 over time.
  • The master site will have OS-DTRS control and switching equipment, a network management system, 90 IP-based logger systems, 50-inch or bigger LED monitors, an antenna system and maintenance systems.
  • Equipment and services are expected to run for at least 10 years and fix network issues faced by personnel on the ground.
  • The system should be equipped to support multi-channel operation for meeting current traffic requirements and should be expandable by 100% in future
  • The system will have talk groups, in which members have the same functions/role, and each radio system will have a unique ID.
