As a service area for social and public activities, wireless network coverage is becoming more and more important. For most parks, there are generally large areas, high user mobility, and low wireless data concurrency rates. If the wireless LAN is deployed in the traditional way, there are problems such as troublesome wiring and high construction cost, so it is inclined to use the wireless method to transmit data over long distances, which saves the trouble of wiring, reduces the construction cost in network deployment, and makes the deployment of wireless APs more convenient.
