Boulder Selects ESChat Broadband PTT Technology for P25 Network
Thursday, October 10, 2019 | Comments

The city of Boulder, Colorado, awarded ESChat a contract to provide broadband push-to-talk (PTT) service, including Project 25 (P25) Inter RF Subsystem Interface (ISSI) interoperability with the city’s P25 network. The order includes ESChat servers that will be hosted at the city’s facilities and collocated with the P25 public-safety system.

The system will provide encrypted voice communications between Long Term Evolution (LTE) smartphones, personal computers, dispatch consoles and P25 radio users. The ESChat network uses an over-the-top architecture that supports broadband users on all wireless carriers and allows users to communicate across carriers, without the need for third-party gateway or interface solutions, a statement said.

This allows public-safety agencies to select the wireless carrier of their preference, taking advantage of the coverage and performance enhancements offered without worrying about blocked or degraded cross-agency communications.

The Boulder system includes several standard features, including Advanced Encryption Standard (AES)-256 encrypted PTT voice, AES-256 encrypted multimedia messaging, and live and historical (bread crumb) location tracking and mapping.

ESChat is First Responder Network Authority (FirstNet) Certified and supports quality of service (QoS) and radio access network (RAN) priority enhancements on the Verizon Wireless and AT&T commercial networks. ESChat is approved for U.S. military operational use by the Defense Information Systems Agency (DISA).
