Abstract
An approach for the location determination by GSM/WiFi/FM and DVB signal strength is proposed in this paper. Location fingerprinting has two stages. The offline stage: RSS is collected at sampling locations to build the database. The online stage: the physical location of client can be estimated by comparing the measured RSS with the stored RSS values in the database.
The GSM signal is robust and easy to be distinguished between two neighbor positions (around 3m). So GSM signal is suitable for location positioning. DVB signal is not robust neither distinguishable in comparison with GSM signal. By reducing the distance of neighbor positions in 3m when doing the site survey, it can not enhance the accuracy of location by using DVB but it spends computing power and times. The characteristics of radio frequency of WiFi and FM signal are between GSM and DVB.
