Abstract

Currently, the IEEE 802.11n wireless local-area network (WLAN) has become most popular for Internet services due to simple installations, low cost devices, and easy extensions. Since access-points (APs) are often densely installed in the field, and may cause high radio interferences. To address the problem, we have studied the AP transmission power optimization method that allocates either the maximum or minimum power to each AP, such that the average signal-to-interference ratio (SIR) becomes largest. The receiving signal strength (RSS) is measured with the possible power combinations to estimate the SIR. However, this study was limited to use of the channel bonding (CB). In this paper, we investigate the feasibility of the AP transmission power optimization method under co-use of CB and non-CB in WLAN through experiments using three Raspberry Pi APs and Linux PC hosts. The experiment results confirmed that the proposed method can optimize the transmission power, once the best CB/non-CB assignment is found.
