Let's take a look at other options for router module . When we choose a router, we need to look at the port of the router. In short, it is the port of the wireless device. If the router does not have the WAN port, there is no way to connect to the network.
Then look at the transmission rate of the router. The transmission rate of the router directly affects the ability of the router to send and receive data. At the same time, it is necessary to consider whether the transmission rate is compatible. The faster the transmission rate of the router, the better.
After considering the above two points, we also need to look at the transmission distance of the router. The longer the transmission distance of the router, the wider the signal coverage of the router.
