GEOLOCATION
LoRaWAN™ infrastructure provides a geolocation solution for LPWANs
• This enables a wide range of applications requiring location determination for battery powered endpoints
• The geolocation functionality is supported by any existing LoRaWAN end-device, eliminating additional cost and requiring no
additional processing power
• the LoRaWAN™ protocol provides two methods for geolocation determination: Received Signal Strength Indication (RSSI) based,
for coarse positioning, or Time Difference Of Arrival (TDOA), for finer accuracy
• TDOA is particularly well-suited for applications requiring low-cost, battery powered end-devices with positioning accuracies in
the 20m to 200m range
• LoRa Alliance members are investigating techniques to provide indoor accuracies of 10m or better (100m gateway density,
improved clock sources, etc.)
- This would compete favorably with indoor Wi-Fi Angle of Arrival (AOA) techniques providing 1m to 3m accuracies
