PTT over LTE with P25 ISSI for DFW

EFJohnson Technologies has selected ESChat to provide ISSI-based secure and interoperable communication at the Dallas Fort Worth Airport (DFW).

The push-to-talk system will provide communication between the LTE and P25 networks at the airport.

The order includes ESChat servers that will be hosted at DFW and co-located with EFJohnson’s ATLAS P25 land mobile radio (LMR) system. The system will provide encrypted voice communication between LTE smartphone users and the ATLAS P25 radio users via the P25 inter RF subsystem system interface (ISSI).

The DFW deployment includes encrypted push-to-talk voice, encrypted multimedia messaging and live location tracking and mapping for all ESChat-enabled mobile phones. The ESChat network uses an over-the-top architecture that supports users on all wireless carriers and allows its users to communicate across the carriers. All ESChat communications are encrypted using AES-256 to ensure voice privacy.

The ESChat product suite supports Android and iOS smartphone devices and personal computers. ESChat can be purchased as a monthly service hosted on the Amazon AWS commercial or GovCloud platforms. ESChat servers can optionally be hosted by the end customer where required. The DFW deployment features ESChat servers hosted on-site and co-located with EFJohnson’s ATLAS P25 system.

The ESChat system has been staged for deployment at EFJohnson and is scheduled to be installed at DFW during 2017.
