ED20W is a smart wristband with GPS/ LoRa®/Bluetooth functions. combined with motion sensors can achieve real-time positioning. With wearing detection, it can realize a real-time collection of health data such as heart rate, number of steps, and sleep. the detected data will be transmitted back to the server platform through the LoRaWAN base station.

Technical Specification


  • Connectivity via LoRa:  communication range up to 1.5KM line-of-sight, 500~1000M in dense urban, compatible with any LoRaWANTM
  • Built-in GPS and BLE4.0, Support Indoor &outdoor real-time tracking
  • Heart rate, body temperature, pedometer: the measurements are made at a configured frequency and automatically send to the LoRaWANTM network. 
  • Real-time AlarmWhen the heart rate exceeds the standard, an alarm is sent.
  • SOS in emergency
  • Long Battery Life:  Battery life as long as 7 days @ 15mins uplink duty cycle, a notification is sent when the battery power falls below 10%. (Class A)


  • Smart safety solution for people working in industrial companies. Such as large oil&gas industries, mining, energy & utilities, real estate, and construction, fire&safety. 
  • Smart senior care, Isolating people from airport, hospital. School, Alzheimer's
