How to use

Install the access point in an appropriate indoor location with good line-of-sight to the intended coverage area. Connect power via PoE-capable switch or an approved power injector and link the Ethernet uplink to the network. Adopt and configure the AP using a compatible Cisco wireless controller or Cisco DNA Center to apply SSIDs, security policies and radio settings. Verify channel planning, transmit power and client density settings through the controller dashboard to optimise performance. Monitor device health and client statistics regularly using the controller’s management tools.

Recommendations

Place access points to avoid physical obstructions and RF interference sources, maintain appropriate spacing for high-density environments, and use controller-driven channel planning and QoS policies for best results. Ensure firmware and controller software are kept up to date and apply enterprise security settings (WPA2/WPA3 where supported) to protect the wireless network.
