Motorola’s Project 25 APXTM Multi-band Two-Way Radios Deliver Interoperability on Demand


World’s first Project 25 multi-band portfolio to provide seamless interoperability, backwards and forwards compatibility to deliver enhanced solutions to mission critical users

APCO 2008 – KANSAS CITY – Motorola, Inc. (NYSE: MOT) today announced the industry’s first Project 25 (P25) multi-band subscriber family, APXTM portable and mobile radios– enabling instant multi-agency interoperability for mission critical first responders. Motorola’s 4th generation P25 subscriber is multi-band (700/800 MHz and VHF), communicates with current and future networks (FDMA and TDMA) and has integrated GPS.

Designed specifically for first responders by applying the science of High Velocity Human Factors (HVHF), the dual-sided portable radio has both an audio and data side providing optimal functionality and loud and clear audio in a compact rugged form factor, which amplifies public safety officials’ ability to keep their communities safer than ever before.

Part of Motorola’s MOTOA4TM portfolio, APX is the first multi-band radio to meet and exceed public safety specifications for mission critical communications and is 15 percent smaller and 50 percent louder than existing Motorola P25 radios. A custom-designed microphone on both the audio and data sides independently suppress most background noise, detects male and female voices and uses a digital vocoder to process and enhance the remaining speech after it is filtered from harsh background noise.

“Multi-agency communication is essential for mission critical operations. APX offers true interoperability and delivers advanced technologies and superior audio quality in one device allowing organizations to streamline the expense of installing, maintaining and operating multiple radios,” said Bob Schassler, corporate vice president of Motorola’s Radio Products and Solutions Group, Government and Commercial Markets – Americas. “APX radios are both backwards and forward compatible working in FDMA and TDMA, which is a testament to Motorola’s commitment to P25 Phase 2. “

Interoperability on Demand
To protect the communities they serve, public safety officials’ success relies on their ability to communicate across federal, state and local boundaries. Instead of requiring two radios to communicate in different agencies’ respective frequencies, APX’s multi-band capability allows first responders the freedom to seamlessly connect between multiple frequencies for better communications with agencies, improved mobility, officer safety and response time. APX will enable first responders to be better prepared for emergencies as it’s designed to be second nature to them.

Mission Critical Form Factor
Designed with input from public safety officials, social sciences, and on-site testing under severe physical conditions, the APX radio is rich with applications including integrated GPS, text messaging, intelligent lighting and user controlled radio profiles. The APX portable’s slip-free T-Grip form factor with raised slanted knobs and buttons is made especially for gloved hands.

“Public safety agencies have been requesting interoperability and enhanced features from their two-way radios, said Jeff Vining, vice president, Gartner, Inc. ”They require mission critical features to take them into the future"

Future Ready Investment
APX two-way radios are backward and forward compatible working on both Motorola’s FDMA and TDMA radio systems, which is a testament to Motorola’s commitment to P25 Phase 2 and interoperability for first responders. When available, TDMA systems will double the voice capacity. APX radios will also support future applications including Bluetooth® as they become available.

Motorola will have a live demonstration of APX at APCO 2008, August 4–7 at the Kansas City Convention Center, Booth 1414. For more information please visit
