说明：  这是《 LoRaWAN-Specification》 的中文译本。《 LoRaWAN-Specification》 是 LoRa 联盟规范的核心协议，由于国内LoRa从业者数量众多，难免有不少伙伴需要中文译本，所以诞生了这个。
(Lorawan specification is the core agreement of Lora alliance specification. Due to the large number of Lora practitioners in China, it is inevitable that many partners need Chinese translation, so this was born.)
