In environments where access points (APs) are mounted on high ceilings (over 6 meters), it's essential to choose an antenna that provides adequate coverage to client devices located at floor level. A low-gain dipole antenna is vertically polarized and offers an omnidirectional radiation pattern, which is suitable for such scenarios. Its radiation pattern ensures that the signal is distributed evenly in all horizontal directions, providing consistent coverage to devices below.
Other antenna types like patch, dish, and grid are more directional and may not provide the necessary coverage for clients spread across the floor area.

In cloud-managed WLAN architectures, the standard procedure involves pre-configuring the access point (AP) profiles within the cloud management platform. Once these profiles are set, the APs are connected to the network, where they automatically reach out to the cloud controller to retrieve their specific configurations.
This method streamlines deployment, ensuring consistency and reducing manual configuration errors.

In an independent autonomous architecture, each AP operates independently without coordination with other APs.This lack of centralized control or coordination mechanisms limits the ability to share control information, such as client roaming data or RF management decisions, across APs.As a result, features like seamless roaming and dynamic RF adjustments are challenging to implement effectively in such architectures.
