The IEEE 802.11n wireless local-area network (WLAN) has been extensively deployed world-wide due to the flexibility, lower cost, and the high-speed data transmission capability at 2.4 GHz ISM band. However, in the WLAN deployment, one key challenge is to optimize the channel assignment of access-points (APs) under the limited number of partially overlapping channels (POCs) to reduce radio interferences, particularly for usage of the channel bonding. In POCs, the frequency spectrums of adjacent channels are partially overlapped with each other, which can cause throughput to drop for concurrently communicating links using them. The accurate throughput estimation of a link is critical in the optimal WLAN deployment. Previously, we have studied the throughput drop estimation model using the receiving signal strength (RSS) from the interfered link for two concurrently communicating links under POCs. In this paper, we extend this model for three concurrently communicating links, based on measurement results. The accuracy of this model extension is verified by comparing the estimated results with the measured ones. |
