Global System for Mobile Communication (GSM) is designed to provide solutions for high increasing number of subscribers of mobile communication services, while the frequency resources is limited. GSM is a digital cellular communication technology with a coverage service area is divided into small areas called cells, and each cell is handled by a site. To anticipate the growth of users number GSM system requires site re-planning that consist of three aspects, namely capacity, coverage and quality. With this site re-planning the number of site eficiency is expected. This final project has made a re-planning simulation for an outdoor coverage site system of GSM radio network 900 and 1800 in Semarang city, which has area of 373.67 km2 and consists of 16 districts and 177 villages, so it can serve customers until 2014. The first step in this final project is collecting data population and digital map of Semarang to be processed to obtain the estimated total population of Semarang in 2014 and the distribution of area types for every district. The second stage is analysis the RF Planning nominal which consists of analysis based on coverage requirement and traffic requirement. The coverage requirement analysis is based on link budget calculation and the cell radius calculation using Okumura-Hatta and Walfish-Ikegami outdoor propagation model. Traffic requirement analysis is based on traffic necessity and capacity of the site. The result of both analysis are then being compared and the biggest nominal RF planning is selected as the basis for next calculations to obtain a recommendation of the radio network design in Semarang. The third stage is site placement analysis. The used site in this design is the reuse partition sectorized system with a dual band frequency, in case of over traffic necessity, the optimization is done by using the technique of cell splitting. From that re-planning simulation for GSM 900 and 1800 radio network outdoor site coverage system in Semarang,can be known the needed number of sites to serve the customers until the year 2014 with a teledensity of 30%, i.e 91 sites with 250 Global System for Mobile Communication (GSM) sectoral cells and 230 Digital Cellular System (DCS) sectoral cells with the highest traffic for the micro cells occurred at sector 3, Sendangguwo village, District Tembalang that is equal to 132.36 Erlang, while the highest traffic for the macro cells occurred in Sector 3 Bamban Kerep village,District Ngaliyan which amounted to 66, 24 E.
