    Master Thesis
    Public safety communication services requirement and their applications in the Turkish geographic structure
    (2008) Usta, Mesut Bedri
    Türkiye is a country which may face with many natural and social disasters due to the geography surrounding it. In this context, fast and effectual intrusion to the disasters is vital for the comfort and prosperity of the country. Certainly, such an intrusion demands a widespread, advanced, and cost-effective communications system which provides interoperability among different foundations like army, police, civil defence, fire brigade, ambulance, and some civil society organizations. At this point two systems come to front as the solution: APCO25 widely used in North America and TETRA widely used in Europe. In the studies of this thesis the aforermentioned two systems are compared with respect to their technical specifications especially the coverage areas; the results obtained are investigated in detail; and finally, by depending on a technology selection model in the literature, one of the systems is proposed as a solution. The coverage analyses are implemented using the computer program National Spectrum Management System (NSMS) developed by TÜBİTAK for the base stations of two alternative systems placed on several certain locations in Ankara province and the results are submitted in a visual manner. Analyses are divided into two classes to compare the coverage area of a single base station and the total coverage area of a group of base stations.
