Location based services are becoming a killer application in the near future. However, before location based services can be deployed, an enabling technology is needed that provides user's location data to the service providers. Several methods for positioning are available today. Main drawbacks in currently available methods are that they require additional hardware, such as, GPS modules that generates extra costs to the consumers, or additionally, they are available only for mobile operators, since they require access to operator's information system. In this research, a positioning method is described, which enables determining geographically enclosed region where the user is located. The method is based on identifying statistically the outer edges of GSM network cells and utilizing that information to determine the user's location. In order to reach wide public we have set three fundamental requirements that our method satisfies. The system has to be cheap to deploy, it must be able to operate on commonly used hardware, and the positioning method has to be independent from the network operator.
