Comparison of web applications geolocation services

摘要

This article deals with WiFi based geolocation in web applications. This is the only one possible method of location in mobile devices (notebook, tablet or smartphone) which are not equiped with a navigation system such as GPS - other known methods such as IP or cellular network location are not commonly used in applications due to their high inaccuracy. The location accuracy has a key role for usability of applications offering location based services (LBS) because a lot of them, widely used by public, are dependent on a very accurate location. Therefore the main goal of this article is an analysis of accuracy of WiFi geolocation services used by web applications in current web browsers. Measurement of accuracy of WiFi geolocation services and comparison between them is the result of this article.
