Abstract: A method for estimating signal strengths for a wireless environment. The method includes measuring a strength of a first radio signal at a plurality of locations in the environment, wherein the first radio signal is transmitted from a radio transmitter at a first location, estimating the strength of the first radio signal at each of the plurality of locations, and estimating a strength of a second radio signal at the plurality of locations, wherein the second radio signal corresponds to a signal transmitted from one of the plurality of locations, based on a difference between the measured signal strength and the estimated signal strength for the first radio signal.

Abstract: A method for assigning channels for access points for a network providing wireless communications coverage for an environment, including assigning a weight indicative of overlapping coverage for each pair of access points having overlapping coverage, and assigning a channel to each of the access points based on certain sums of the weights to minimize coverage overlap between access points operating at the same channel.

Abstract: A system for determining a position of a user. The system includes a distance sensor in communication with a position tracking device. The distance sensor is for detecting movement by the user, and the position tracking device is for determining the position of the user based on detection of movement by the user and a relative change in direction input from the user.

Abstract: A method for configuring access points of a network providing wireless communications coverage for an environment, including determining a coverage radius of an access point at certain locations within the environment, determining an average coverage radius of the access points for the environment based on the determined coverage radii, positioning the access points at locations within the indoor environment to provide continuous radio coverage for the environment based on the average coverage radii, assigning a weight indicative of overlapping coverage for each pair of access points having overlapping coverage, and assigning a channel to each of the access points based on certain sums of the weights to minimize coverage overlap between access points operating at the same channel.
