For example, Ruijie's airport passenger Internet access solution, which is customized for airport scenarios with special APs, has particularly good signals through low-angle coverage and prevention of signal interference, and can also locate terminals and count customers through Wi-Fi positioning technology, as well as build a multi-airport big data operation platform through extended business applications based on LBS location positioning, not only solving the wireless problems of airports, but also contributing a lot to overall operation and maintenance of airports. This will not only solve the wireless problem of airports, but also help the overall operation and maintenance of airports.
