Project 25 Common Air Interface

Congress and the NTIA (National Telecommunications and Information Administration) have issued a Narrowband mandate for Federal LMR systems to migrate to more spectrally efficient 12.5kHz channels.

By mandate, many Federal LMR users had to transition existing VHF systems from 25 kHz wideband channels to 12.5 kHz narrowband channels. UHF wideband users (406.1 - 420 MHz) have until January 2008 to make the transition. DoD users in the 380-399.9MHz band are migrating to narrowband in compliance with DoD LMR Policy, dated 1
August 2001.

M/A-COM's P25^IP fully meets the NTIA. M/A-COM has combined the benefits of our IP-based network-centric solution with the standard common-air-interface of P25. The combination, called P25^IP, or P25 to the Power of IP, is the best of two worlds for Federal users, namely:

P25^IP combines the global ubiquitous IP infrastructure standard with the P25 digital over-the-air protocol.

M/A-COM's P25^IP system is a drastic shift from this circuit switched central control world, to the flexible packet switched IP universe. The system provides both network-level and over-the-air radio level interoperability. This state-of-the-art IT solution provides flexibility, scalability and is future-ready.

Together, digital and IP allows M/A-COM's P25^IP to provide features formerly associated only with trunked systems.
These IP-enabled features include:
• Integrated voice and packet data
• Scaleable architecture
• End-to-end encryption
• Over-The-Air Programming (OTAP) and Over-The-Air-Rekeying (OTAR)
• COTS (Commercial Off-The-Shelf) routers and workstations
• Lower life-cycle costs
