New Delhi: While phasing out its current Tetranet wireless networkDelhi Police is procuring an advanced digital trunking radio system that will take care of its network needs for the next 10 years.
Estimated to cost Rs 100 crore, police commissioner Rakesh Asthana is learned to be keen on incorporating “Make in India” components to have a reliable and secure network system for police communications.
The new wireless radios, which would operate at 800MHz frequency band, would be procured in batches over five years. Around 12,950 radios are likely to be procured in the next one year and 7,000 in the next lot. Police plan to procure 5,000, 2,500 and 2,500 radios in the subsequent years, documents reviewed by TOI suggest.
Wireless radio setups are not only required for internal communication, but they also form a critical part of police action in the form of logs of wireless chats recorded when cops are rushing to or have reached any crime scene.
The existing Tetranet sets have several network-related shortcomings. Sources said the contract for maintenance expired years ago after which efforts were made to purchase an updated and reliable communication system in which components made in India were used.
While police earlier faced network coverage issues, the new system would give better communication now, said a source.
This time, Delhi Police intends to install an “Open Standard Digital Trunking Radio System” with wide-area and multiple site operations for pan-Delhi coverage. The procurement would have been made earlier, but the higher authorities were keen on having a Made in India setup. This led to some delay. The purchase is expected to wind up soon. The first decisions may be made around mid-August as many firms now use Indian-made components.
The new system would be equipped with an IP-based Digital Voice Logger System, which would provide audio recordings of all channels while being able to reconstruct the entire scenario of a radio communication and the data between the wireless dispatcher and the PCR van related to any crime incident. The recording system would be integrated with ERSS-112 (the police control room).
It would support at least 250 Talkgroups with members having the same functions or role to communicate with each other. There would be a provision to assign not less than 15,000 unique individual radio IDs with the ability to expand it to 30,000 in the future.
“There will be at least four levels of priority, including emergency and operational features, for timely processing of calls. Whenever a subscriber radio will leave the coverage area, an alert will be sounded. Dispatch console will be alerted too,” said an officer.
