Abstract
This paper details the development of a location based service (LBS) application for GSM mobile terminals. The motivation behind the application is the worldwide acceptance of GSM, the growing interest of users for innovative services, the emergence of a new generation of mobile terminals and the adoption of standards and methods that facilitate the development of applications. Also, the adoption by different countries of legal requirements for the location of mobile systems due to safety and emergency has increased the interest in these applications. The application consists of two types of software. One developed for the mobile terminal, executed by the user, in a Nokia platform Series 60 which is based on Symbian OS. Another was developed in Java and installed on a PC (connected a cell phone) which works as a short message server (SMS) and also as a location server. The application was tested on an area located in the city of Quito, Ecuador. The test area was divided into sectors where multiple experiments were run to estimate the distance to business premises sought by possible users.
