How to use

Install the AIR-CAP2702E-E-K9-RFB according to site RF planning and mounting guidelines, ensuring suitable placement to cover the target area and minimize interference. Connect the access point to the network and power it through the appropriate PoE-enabled switch or power injector as specified by Cisco. Adopt a Cisco wireless controller for centralized configuration, firmware management and policy enforcement. Configure SSIDs, security (WPA2/WPA3 where supported), RF profiles and QoS settings in the controller to match your network requirements. Monitor CleanAir alerts and RF statistics to identify and resolve interference or coverage issues.

Recommendations

Place access points according to a documented site survey, use controller-based RF management to optimize channel and power settings, and keep firmware up to date to maintain security and CleanAir accuracy. For dense deployments, plan capacity and channel reuse to avoid co-channel interference and maximize client performance.
