Messaging, location sharing and SOS alerts for teams working where there is no mobile signal. Each person carries a badge paired to their phone, badges relay messages over a LoRa mesh, and solar relays on high ground extend reach. It suits field crews, patrols, trekking groups, remote camps and site workers, and an optional gateway can pass data to a platform.

Questions
No. Badges talk to each other over LoRa, and phones connect to badges over Bluetooth.
The hardware covers 862 to 930 MHz, which includes India's 865 to 867 MHz band. Devices must be set to the Indian band, and we confirm this before dispatch.
Within the mesh they reach teammates directly. To reach a control room you need a gateway and an integration with your dispatch system.
Tell us the site and the problem. We come back with a pilot plan and a priced hardware list.
