Impact of Weather Conditions on Fingerprinting Localization Based on IEEE 802.11a

In this paper we deal with implementation of outdoor positioning system based on WiFi network works in 5 GHz frequency band (IEEE802.11a). Positioning solution based on 5 GHz WiFi seems to be interesting, because the interference in this bandwidth with other networks is not so critical in comparison with 2.4 GHz WiFi. Positioning was based on fingerprinting method utilizing received signal strength information. The goal of the paper is to investigate an impact of different weather conditions during positioning process on positioning accuracy. Performance of the implemented positioning method was tested in two basic weather conditions, i.e. bad condition: raining and snowing, good condition: sunny. The experimental scenarios were implemented in the outdoor environment.
