Abstract
This paper presents an indoor location scheme based on wireless local area networks, where the position of a mobile terminal is estimated according to the measured signal-to-noise ratio (SNR) information from multiple access points. With the antenna pattern-measurement method for measuring the SNRs, pretty good location estimates can be obtained. Our experimental results show that more than 85 percent of the estimated locations have error distances less than two meters.
