FRA Coverage Overlap Percentage Criteria

The coverage overlap Factor COF is computed BY FRA using the NDPneighbor list data. The COF is significant because it indicates the percentage of an AP’s cell area with overlapping signals from other APs. The overlapped signals are usually 67dBm or stronger. Overlapping of two AP cells on different channels makes it difficult to get wireless clients evenly distributed across the two radios. Some of the methods used by the FRA to influence the BSS clients able to join the bandwidth include 802.11 probe suppression, 802.11ksite report, and 802.11Vbss transition. FRA monitors client RSS in micro/macro cases to steer clients towards the micro or macro BSS depending on the signal strengths thresholds.

Their benefits include but are not limited to; their ability to address nonlinear traffic, enhance the High-Density Experience (HDX) with one AP, permit one AP with one Ethernet drop to function like two 5–GHz APs, and solves the problem of 2.4–GHz over coverage and avails the Creation of 2 diverse 5–GHz cells doubles the airtime. The FRA takes advantage of the dual-band radios included in APs like 4800, 3800, 2800, and the new 11AX APs. Its unique feature added to the RRM to analyze the NDP measurements manages the hardware used to determine the role of the new flexible radio in the wireless network
