In this paper we study the use of GSM signal strength information as a method of inferring position. Location fingerprinting using 802.11 wireless networks is a popular positioning technique. Recently, research has been published that has applied this technique to cellular networks. Cellular networks offer wider coverage than 802.11 and enable context-aware applications to be built upon the already...
In this paper, we present a strategy and set of algorithms for developing qualitative positioning services that are specifically optimised for the environment where they are to be deployed. We argue that for many context-aware applications, this may be more appropriate than more common quantitative location systems, where the positioning API may make unrealistic demands on the underlying measurement...
