OPEN STANDARD DIGITAL TRUNKING RADIO SYSTEM
News: For
better communication, Delhi Police to design, adopt high-frequency radio system
What's in the news?
● The
Delhi Police will soon move to a
more efficient internal communication
system, aimed at faster exchange of information and bigger networks.
● The
force is set to design, install and supply the ‘Open Standard Digital Trunking
Radio System’ (OS-DTRS) and will phase out the current tetranet wireless
network services.
● The
project will cost close to Rs 100 crore, tenders for which were issued on
December 2.
Open Standard Digital Trunking Radio System:
● The
trunking system provides multiple
channels and common groups for policemen.
● In
this way, they are communicating with more personnel using fewer groups and 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.
OS-DTRS Consists of:
● As
per documents released by police, 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
number of frequency spots required for meeting 15,000 radios operation as per
traffic norms should be projected.
● The
system will have talk groups, in which members have the same functions/role,
and each radio system will have a unique ID.
