METHOD OF ESTIMATING THE POSITION OF A USER DEVICE |
摘要 |
Data concerning the strength of signals received from electromagnetic signal sources within a building is obtained at a plurality of points. Instead of storing the raw data for use in positioning, the data for each electromagnetic signal source is fitted to a function of received signal strength with distance from the electromagnetic signal source. This data is then used to estimate the position of a user device. The advantage of the invention is that the amount of data which requires to be stored is significantly reduced. |
