Advanced Technology Provides an Answer
FDMA (Frequency Division Multiple Access) is a proven technology that is widely
used today in radio systems and is part of Project 25 Phase 1. FDMA carries one
call per channel. TDMA (Time Division Multiple Access) will be part of P25 Phase
2 requirements and it provides double the voice capacity. Customers can add
more users to their system or more data services without the need for additional
frequencies or infrastructure.
The APX radios support both P25 Phase 1 and Phase 2 technologies seamlessly.
Using Motorola's unique Dynamic Dual Mode (DDM) capability, the radios
dynamically switch between FDMA and TDMA without the user having to
change channels. This provides complete interoperability and flexibility to
communicate with existing and future networks.
APX is Fully Compatible with the Motorola ASTRO 25 Network
APX 7500 multi-band radios were designed to work with ASTRO 25, Project 25
standards-based communications networks. With integrated voice and data
capabilities, the ASTRO 25 network offers improved communications between
multiple agencies, from everyday operations to disaster response.
