Sepura is known as a leading supplier of TETRA devices. But the company's recent progress on the 3GPP Mission Critical Push-to-Talk (MC-PTT) front arguably makes it the top-of-class option for early movers to MC-PTT services.
Samsung Networks and Etherstack are trialing the Mission Critical Push-to-X (MCPTX) solution in Australia. A first for the region, the trial includes the incorporation of Etherstack standards-based P25 Interworking Function.
The GCF and TCCA efforts to create a foundation for 3GPP MC-PTT conformance testing have borne fruit, and test laboratories can now begin issuing conformance marks. This progress is an essential driver for economy-of-scale and broad interoperability. But the impact may vary depending on national priorities.
In this live demonstration of DFR support, Aerodome highlights its integrations with remote Beyond Visual Line of Sight (BVLOS) robotic docks, Computer Aided Dispatch (CAD), and airspace monitoring systems that include ADSB and radar.
Dryad Networks focuses on early fire detection through distributed sensors mounted in forests. Clever design choices, including solar, supercapacitors, LoRaWAN, and up-link flexibility, make it a solid complement to infrared cameras and satellite systems for next-generation rapid wildland fire observation.
I joined up with John Dundas' merry band of radio experts as they deployed DMR, TETRA, and Push-to-Talk over Cellular solutions across the widely scattered venues hosting the inaugural UCI Cycling World Championships. What I saw points to a growing importance of PoC in the high-pressure world of Mega-Sporting events.
