AT&T has announced new features to its enhanced push-to-talk service that are designed to provide improved interoperability with enterprises’ existing LMR and dispatch systems, as well as a broader portfolio of devices and accessories that are geared for myriad use cases, according to Igor Glubochansky, AT&T’s executive director of advanced mobility solutions, in a recent interview with IWCE’s Urgent Communications.
Excerpted from this article, Glubochansky said that the carrier’s Dynamic Traffic Management offering—providing different levels of prioritized traffic to public-safety and non-public-safety users of LTE services—has generated “a lot of activity and excitement” in the industry that has sought greater quality-of-service assurances from cellular push-to-talk services.
At IWCE 2016, AT&T demonstrated that its enhanced push-to-talk service is interoperable with console vendors such as Avtec and Zetron using a P25 CSSI gateway, Glubochansky said. Announced last year, IP-based interoperability between push to talk and two-way-radio dispatch systems is now commercially available, he said, “So, you can integrate push to talk without a donor phone or an on-premise solution.”
“Now, you have a bit of priority, but you still want to run your push to talk in parallel with your two-way radio system—that’s very common,” Glubochansky said during an interview with IWCE’s Urgent Communications. “We now have launched IP-based interoperability between push to talk and two-way-radio dispatch systems.
Glubochansky emphasized that AT&T officials do not perceive the company’s enhanced push-to-talk service as a replacement for traditional LMR push-to-talk voice communications used in mission-critical environments such as public-safety first responders at an incident scene. But AT&T’s enhanced push-to-talk offering can be useful in several other scenarios, especially when it is bundled with the carrier’s Dynamic Traffic Management offering to ensure greater reliability, Glubochansky said.
