Applications of TETRA in Police Networks Devdarsh Jain Product Marketing Director Artevea Digital Limited 1 st Indian TETRA MoU Conference New Delhi 8 th February 2006

Agenda An Overview Requirements Solutions TETRA: Features & Functionalities Enhanced Applications A Typical TETRA Network for Police Conclusion

Overview Republic of India comprises of 28 states & 7 (Union Territories) Each State maintains its own Police Force responsible for Internal Security Military and Paramilitary forces are deployed in special situations to maintain internal security.

A Typical State Police Organization State Police Headquarter (PHQ) DHQ PS OP PS District Headquarter (DHQ) DHQ OP Police Station Out Posts

Requirements Strategic Requirements Regional wireless Voice + Data Secure Integration to Control Room Integration to PSTN Migration strategy for Statewide Conventional Radio Network (HF/VHF) Cost effective

Operational Requirements Intra-district Communication DHQ to PHQ and vice-versa DHQ to Police Stations & Out Posts and vice versa PS / OP to Police Patrol Teams and vice versa Border Communication (inter-district / intra State) Mobile Communication at any place during movement of VVIP/VIP/Higher official. Top management and control centre in state capital Local Communication for temporary deployments/events/disaster management/missions

Limitation of Conventional Solutions –Devoid of benefits of Digital schemes of modulation – Need for intensive Frequency Management at various levels – Spectrum Inefficient – Need for External secrecy devices – Limited Data transfer speeds – Limited capabilities for interface to new IP Voice and Data networks

Modernization of Police Wireless State Wide Area Network (SWAN) – Create state of art IP backbone interconnecting PHQ to DHQ and PS Police Network (POLNET) – Satellite based Integrated Network to interconnect PHQ to DHQ and PS with Voice, Data and Fax Challenges still to be met – Rapid deployments for temporary deployments/events/disaster management/missions Establishment of strong command and control centre Enhanced Data Rates for Police Teams/Patrols Advanced spectrum efficient wireless communication for rapidly growing state centre/cities
