The IEEE 802.11n wireless local-area network (WLAN) has been extensively deployed around the world 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 small number of partially overlapping channels (POCs) to reduce radio interference, particularly for the channel bonding. In POCs, the frequency spectrums of adjacent channels are partially overlapped with one another, which will result to low throughput for concurrently communicating links using them. The accurate throughput estimation of a link is critical in the optimal WLAN deployment. Previously, we 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, based on measurement results, we have extended this model for three concurrently communicating links. The accuracy of this model extension is verified by comparing the estimated results with the measured ones.
