Staggering APs vertically and using non-overlapping channels are key strategies. Understanding these ensures robust coverage and performance.
The practice bank addresses high-availability features such as Stateful Switchover (SSO) and N+1 redundancy to ensure continuous network operation. Anchor controllers manage guest traffic securely. Mobility groups facilitate seamless roaming across controllers. Load balancing distributes clients evenly. These design choices are critical for mission-critical environments like hospitals and universities.
In high-density venues, technologies like MU-MIMO, 802.11ac Wave 2, and directional antennas are vital. RRM dynamically adjusts channels and power to reduce interference. QoS prioritizes real-time traffic. Band steering guides clients to the 5 GHz band. These optimizations ensure performance under heavy load, as tested in stadium and conference center scenarios.
Study workflow
Walk the facility with a spectrum analyzer and wireless survey tool. Identify sources of interference (e.g., microwaves, neighboring APs). Measure signal strength and SNR at various locations. Document findings and propose AP placements that minimize overlap and co-channel interference, especially on multi-story buildings by staggering vertical placement.
On the wireless controller, enable 802.11r (fast roaming) for the SSID. Ensure all APs in the mobility group support the standard. Verify that client devices are 802.11r capable. Test roaming by moving a client between APs and checking for minimal latency during handoff. Adjust thresholds if needed.
Deploy a pair of wireless controllers in an SSO cluster. Configure them as primary and secondary. Ensure they share the same configuration and are connected via a reliable high-speed link. Test failover by manually disabling the primary controller and verifying that clients remain connected with minimal downtime.
