Abstract
Horus is an RF-based location determination system. It is currently implemented in the context of 802.11 wireless LANs. The system uses the signal strength returned from the access points to infer the user location. The signal strength of AP corrected in the online can not be found in the set of radio map sometimes. As result, we can not get the probability and infer the location of user. Papers about Horus tell nothing about it. This paper aims to give the reason and approach to deal with this phenomenon.
