We're pleased to share that an AT&T government and public safety customer has adopted Enhanced Push-to-Talk (EPTT) and LMR interoperability. Steve Graves, chief information officer for the city of Richardson, Texas, tells Donny in this APCO 2016 interview that the city has been pleased with how easy and affordable it has been working with AT&T to get the EPTT service setup and going, and that it took only 15 minutes to get the ISSI connections betwen their trucked radio system, an 800 MHz Airbus system, direct connected to AT&T for EPTT interoperability,
The first set of EPTT users are the field workers in public works, the water department, and streets. Steve reports that employee reaction has been very positive. And with the city planning to roll out a new work order/asset management system soon that has mobile components, those workers will be able to use a single smart device for both their data system and communications. The LMR interop enables those departments to communicate with 911 and public safety when needed, and they also have their own separate talk groups set up. This has relieved the radio system of some traffic, and returned radios used by city crews to public safety use.
While the Richardson public safety departments will continue using their P25 radio system, in their phase 2 rollout, public safety users also plan to use the carrier PTT technology to supplement communications on the existing P25 system.
