The latest generation of facemasks from MSA and 3M Scott reduce the problem of voice amplification by relaying the mask user's voice over a Bluetooth connection to the user's portable radio. L3Harris showed how it supports the capability.
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.
