Motorola Solutions rolled out the industry’s first commercially available Project 25 (P25) Phase 2 products Monday and announced 16 customers for the TDMA-base technology including the state of Maryland and a Kentucky utility.

Motorola announced that it is shipping P25 systems with P25 TDMA trunking as part of its public-safety portfolio. The P25 TDMA trunking feature doubles the voice capacity of P25 Phase 1 FDMA technology for more efficient use of spectrum. Current P25 Phase 1 customers require only a software upgrade to the new platform, said Brenda Herold, Motorola Solutions corporate vice president.

Motorola’s end-to-end P25 TDMA trunking functionality is included in the ASTRO 25 system infrastructure and dispatch consoles, as well as in the portfolio of TDMA devices, APX radios and the newest APX product, the APX 7500 consolette. P25 TDMA trunking functionality can be deployed on an existing ASTRO 25 system. G-series-based site products, MCC 7500 consoles and APX subscribers can be upgraded for P25 TDMA operation using software, said a company statement.

The state of Maryland is rolling out a P25 Phase 2 system under a $345 million contract awarded to Motorola last November, said Ray Lehr, Maryland’s statewide interoperability director. The state has built some towers for the network using Public Safety Interoperable Communications (PSIC) grant money.

“About every state agency has a different radio system, so we’re looking to consolidate so we have one system,” said Lehr.

State officials are finalizing the project’s phase one design, including coverage for the Maryland Transportation Authority Police. The equipment will be staged in Schaumburg, Ill., in December with installation and testing scheduled for mid-2012. The system is expected to go live by the end of next year, Lehr said.

The Bowling Green Municipal Utilities will implement its P25 TDMA system later this year. “It will enable the reliable communications we need to provide service to our utility customers throughout the Bowling Green area and to increase coverage for on-call personnel in surrounding Warren County,” said Kathleen Duvall, technical services supervisor, Bowling Green Municipal Utilities. “P25 TDMA is a critical part of the system by providing the capacity we need today as well as allowing planned growth of our radio users in the future. In addition, the system will give us the interoperable communications we need with other P25 radio systems in the area.”

Motorola’s Herold said the 6.25-kilohertz technology’s Dynamic Dual Mode feature offers seamless interoperability between P25 FDMA and P25 TDMA users, automatically allocating a call based on available resources without user intervention.

Motorola will demonstrate the P25 Phase 2 technology at the Association of Public-Safety Communications Officials (APCO) International conference and exhibition in Philadelphia this week.
