Hiking routes are mostly fixed, but members easily separate and mountains lack signal, making supervision hard. This solution sets up a LoRa base station at camp; personnel wear badge positioning terminals,Deploy one LoRa relay every 2~3 km along the routeForms a signal corridor; once someone exceeds coverage, the team manager or another member with a handheld receiver can view their position offline via phone.
Routes are fixed, but people separate; mountains lack signal, and accidents leave no way to find them
Hiking routes in mountains, canyons, and dense forests lose public network year-round; ordinary phones and locators cannot report, so separated members are immediately "lost."
Even with a fixed route, members differ in stamina and pace; forks, night paths, and getting lost easily cause lag, making it hard for leaders to track everyone in real time.
When lost, injured, or hypothermic, positioning for help is impossible; search and rescue relies on "shouting across the mountain," time-consuming, laborious, and dangerous.
Camp base station + one relay every 2~3 km turns the "signal-less mountain trail" into a supervised communication corridor
Handheld LoRa receiver, can check position nearby even without signal; can also be mounted on a drone for stronger, wider aerial signal
When a member leaves the relay corridor and exceeds base station coverage, the team's manager or another member carryingHandheld Receiverβ It actively receives LoRa signals from nearby badges, then transmits viaBluetooth (BLE) pushed to phone.
Even in areas entirely without public network, opening the phone App shows the separated teammate'sDirection and distance, trail-following search, quick regrouping or rescue.
π Drone Aerial Relay:The receiver can also be mounted on a drone aloft. High altitude is unobstructed with stronger, wider signal; it can simultaneously receive LoRa signals from multiple separated members and serve asAerial relayForward to ground handheld receiver or phone, greatly expanding search-and-rescue radius and shortening find time.

| Alarm Type | Trigger Condition | Level | Disposition Method |
|---|---|---|---|
| π¨ SOS distress | Member presses badge SOS button | Emergency | Platform popup + location, immediate nearby rescue |
| π§ Route deviation | Position continuously deviates from the planned hiking route | Emergency | Remind the leader to prevent getting lost |
