四次通訊實驗測得 LoRa 最大通訊距離為 1.96 公里。
Four communication tests measured a maximum LoRa range of 1.96 km.
LoRa 距離為四次通訊實驗的實測結果;其餘為依目前排程、封包大小與耗電條件計算的設計估算。
LoRa ranges are measured results from four communication tests. Other figures are design estimates calculated from current scheduling, packet-size and power assumptions.
