In this paper, the authors describe an empirical study on the impact of throughput performance when transmission power is adjusted. This experiment was conducted in an office environment for an OFDM-based wireless communication system such as Wi-Fi 802.11g protocol network. They present a power selection mechanism based on intuitively learning one of the attributes which then triggers the power adjustment. They show that client's similar throughput performance can be obtained at reduced transmission power thus prevent an access point from maximizing power unnecessarily.
