LoRa都是星形网络,没有mesh网络。LoRa设备要通过网关的4G、Wifi、网线等接入公网。其中“LoRa模块+网关+数据中转传输”部分,已经有大量成熟解决方案。 MCU连接LoRa网络,跟连接2G和NB-IoT网络的方式是类似的,重新照着模块AT指令写一遍就好了。如果上FreeRTOS之类的小系统,大部分网关厂家有参考代码可以直接搬过来用。
3.WIFI定位 WIFI定位和基站定位方法类似:定位器搜索周围的WIFI路由器的信号,根据WIFI信号强度判断和WIFI路由器之间的距离,再根据WIFI路由器的位置,用三角定位方法计算出定位器自身的位置。 WIFI路由器信号范围只有一百米左右,因此WIFI定位比基站定位精度高很多,可以达到10-30米的精准度。
