Setups that work.
01Search & rescueAssign sectors, see every team live and keep talking when you are far past the last cell tower.02Hiking groupsSee the whole group on the map, send a message when someone falls behind, and do it without a SIM.03Events & festivalsStewards, medics and security on one live map when thousands of phones jam the network.04Security patrolsLive positions, recorded routes and checklists for each round, on sites where coverage is unreliable.05OverlandingKeep every vehicle on the map across deserts and mountain passes, with weather overlays for the route ahead.06Remote monitoringGreenhouses, weather stations, pumps and servers on one dashboard, with alerts before something breaks.
