Method for estimating signal strengths
First Claim
1. A method for estimating signal strengths for a wireless environment, comprising:
- 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 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.

14. A computer readable-medium having instructions stored therein which, when executed by a processor, cause the processor to:
-
determine a first estimated signal strength at a plurality of locations in the environment for a first radio signal, wherein the first radio signal is transmitted from a first location; and
determine a second estimated signal strength at the plurality of locations for a second radio signal, wherein the second radio signal corresponds to a signal transmitted from one of the plurality of locations, based a difference between a measured signal strength at the plurality of locations for the first radio signal and the first estimated signal strengths.
