Push/Talk Device Lets Smartphones Operate Off-Grid
Beartooth connects to smartphones and enables users to communicate in areas with little or no phone signal.
Keeping touch with others while lost in the outback or hiking in the mountains can be difficult. Operating in areas with low signal or an overloaded network can reduce connectivity and make it hard to stay in contact. A new device called Beartooth is looking to solve this dilemma.
The portable device works on a sub 1GHz bandwidth, and connects to users’ smartphones via Bluetooth technology. The system acts as an antenna to establish a two-mile radius wifi network, linking all users in the immediate area. Beartooth operates on an off-grid network, so for hikers in nature or friends stuck in an underground nightclub, they can message each other in the given area without a main network or local wifi connection.
Users can also share their locations with friends and view their position with offline maps. By creating an off-grid maps, Beartooth hopes to establish a community of adventurers who will share trails with others and discover new paths. Beartooth can also double as a mobile phone backup battery and is available for pre-order for USD 99.
