Indoor Positioning Using Spatial Power Spectrum

October 1, 2005
Author(s)
Kamran Sayrafian, D Kaspar
A simple technique to estimate the position of a given mobile source inside a building is based on the received signal strength. For this methodology to have a reasonable accuracy, radio visibility of the mobile by at least three access points is required

Link Variability Studies
