LoRa
- LoRa - Long Rang - PHY 层
- 低能耗、长距离 - 例如乡村可达到 10KM
- 27 Kbps - 0.3 Kbps
- 基于 chirp spread spectrum (CSS)
- 433 MHz, 868 MHz 欧洲 ,915 MHz 澳大利亚及北美洲, 923 MHz 亚洲
- LoRaWAN - Link 层
- LoRaX - LoRaWAN Range extender
- LPWA = LoRa+LoRaWAN
- SF - spreading factor - 扩散因子
- LinkWAN
- 芯片: SX1261, SX1262, SX1268, SX1272, SX1276, SX1278, SX1302
