Closed Loop RF Management Algorithm for Enterprise High Density WLANs
Source: University of Washington
The growing adoption of 802.11 networks in the enterprise segment has led to the emergence of High Density (HD) WLAN scenarios where large (100-1000) numbers of clients are serviced by 10-100s of APs in a multi-cell environment. This leads to an interference limited environment due to limited spectrum availability; hence network design for throughput scalability becomes the primary design challenge. Current industry practice leans towards centralized RF management of HDWLAN Enterprise deployments using a RF controller. The main focus of the work in this paper is a new CS/RT (Carrier Sense/Receiver Threshold) adaptation algorithm in which APs, Clients and RF controllers participate collaboratively to mitigate the interference.
