Motorola Solutions announces new mobile radio, enhancements to its P25 platform

ORLANDO—Motorola Solutions today will unveil a new P25 mobile radio that operates on its ASTRO 25 systems and will highlight key features enabled by the 7.17 release of ASTRO 25 software today at APCO 2016.

One of the key features of the APX 8500 all-band mobile radio is its ability to leverage LTE connectivity from a VML750 modem installed in the public-safety vehicle, if the ASTRO 25 data capability is interrupted by continuous voice transmissions during a busy incident, according to Anatoly Delm, Motorola Solutions’ director of global infrastructure marketing.

“Let’s say that you have a major incident, everybody’s talking all the time and the ASTRO network is being used all the time, it can [offload] some of the data communications, like GPS, to broadband—public-safety LTE or commercial LTE, depending on what the modem is operating on,” Delm said during an interview with IWCE’s Urgent Communications.

“So, you’ve got this combination of the best of both worlds, where your voice communications are continuing over the ASTRO network, and your data communications—if the ASTRO network is too busy, because of a major incident—can be carried on by an LTE network from the same car.”

Meanwhile, the 7.17 release of ASTRO 25 software will provide system users and operators with features that are designed to improve the reliability and usability of the P25 network, Delm said.

One enhancement is a more efficient way to execute over-the-air software updates, Delm said.

“Ordinarily, what happens is that the software update has to travel to one radio at a time. If you’ve got a large enough fleet, it could take days or possibly weeks [to complete the software update for all radios],” he said. “In this case, the software is being continuously broadcast, kind of like on repeat. In the meantime, all of the radios continue to function as normal—you can talk on them, and none of the functions are disrupted.

“Once a radio has received all of the packets that it needs, it can then give the user the [a notification] that the update is ready and asks whether the user wants to install it. If they say ‘Yes,’ then the radio is updated. This means you can reduce your update time to maybe a few hours, depending on the size of your fleet. But you certainly don’t have to do it one at a time.”

Other new capabilities included in the latest ASTRO 25 software release include personnel accountability—often used for roll-call functionality on a fireground or other incident scene—over trunked systems, Delm said. Previously, this capability existed only in conventional mode.
