Abstract
Universal service was defined for basic wired services until the 21stcentury. As an emerging country, Turkey was also using universal service fund for this purpose. Turkey has also been expanding the mobile coverage during the last decade. There have been many projects to achieve this goal. The last one of such studies involves combining universal service with rural coverage. This new approach to universal service which is called “Universal Service Study for Mobile Coverage” is expected to bring coverage to the last 2128 locations that do not yet have GSM coverage. This paper explains the process up to now and ongoing Universal Service approach. The related data obtained from various sources is provided along with the model reflecting the determination of candidate locations for universal service coverage.
