Samsung Networks and Etherstack demonstrated impressive live transmissions between Project 25 handset devices, 3GPP Mission Critical Push-to-Talk clients, and a console application.
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.
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.
