LPWAN

LPWAN(Low-Power Wide-Area Network,低功率廣域網路)也稱為LPWA (Low-Power Wide-Area) ,或 LPN(Low-Power Network,低功率網路),是一種用在物聯網(例如以電池為電源的感測器),可以用低位元率進行長距離通訊的無線網路[1][2]。低電量需求、低位元率與使用時機可以用來區分LPWAN與無線廣域網路,無線廣域網路被設計來連接企業或用戶,可以傳輸更多資料但也更耗能。LPWAN每個頻道的傳輸速率介於0.3 kbit/s 到 50 kbit/s之間[3]

LPWAN可以用來建立一個私有的無線感測網路,但也可以是一個第三方提供的服務或基礎設施,這使感測器的擁有者可以直接部屬感測器,而不必投資經費於閘道器的建設。
