The performance of wireless APs varies from vendor to vendor. There is a limit to the concurrency and coverage capability of a single AP. A single AP cannot solve the full coverage demand of the scene.

In multi-AP networks for wireless coverage scenarios, user terminals need to switch between multiple APs when roaming, and the choice of AP location and the design of the AP roaming switching mechanism can have an impact on roaming speed.

In outdoor open scenes, AP location selection is difficult, which requires APs with strong coverage capability to reduce the cost of AP deployment and improve the user experience at the edge of network coverage.
