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.
Mission Critical Push-to-Talk (MCPTT) is a vital element of future LTE-based critical communications systems. The industry has made tremendous progress producing clients and systems that work. But effective direct device-to-device communications is an extraordinarily important requirement that remains out-of-reach. With the clock ticking to shutdown of its legacy emergency services PTT network, the UK is now forced to embrace a "Plan B". Is this the answer for the rest of the world?
