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 WLAN design software, defining different “requirement areas” allows the designer to assign distinct RF and performance requirements to different parts of the floor plan. For instance, a voice-critical conference room may require –67 dBm minimum signal strength and a specific SNR, whereas a storage area might only require basic coverage.

From CWDP-305:

“Requirement areas allow WLAN designers to set different RF performance targets such as minimum signal strength, SNR, and data rate for specific parts of the deployment area. This enables tailored design strategies.”

When designing a WLAN for applications like Telnet, which are sensitive to latency and require consistent connectivity, it's crucial to minimize co-channel interference.Reducing the AP transmit power helps in creating smaller cells, thereby limiting the overlap between adjacent APs operating on the same channel.This approach reduces contention and interference, ensuring a more stable and reliable connection for latency-sensitive applications.
