WiFi is mainly located in a specific scene area, with natural scene advantages (cafes, hotels, restaurants, shopping malls, etc.). ). The Internet demographic dividend is gone, and online traffic is climbing. The offline real traffic obtained by offline WiFi will become more and more important. It not only has a lot of data, real traffic and richer scene tags, but has been regarded as a new source of traffic by many large companies. The commercial value advantage of WiFi is obvious. 5G can bring better connection between people and everything in the mobile state, but its cost performance and scene value mining in specific scenarios have not been fully verified.
