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.

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
