Text in English ; Abstract: English and Turkish Includes bibliographical references (leaves 57) xii, 97 leaves The thesis reports the design and realization of a fixed cellular terminal (FCT) device which works with a mobile phone as a GSM Module. The design is emphasized at the structure not to be complex and suitable to be used in mass production. Before starting our design, our currently available FCT products and their functional properties are studied and the most important and usefull properties are fixed. This design is not only a theorical project, it is also realized as a mass product and take part in the market as a product. Bu tezde GSM modül yerine bir mobil telefon kullanılarak yapılan bir sabit GSM terminalinin tasarımı ve gerçeklenmesi çalışmaları anlatılmaktadır. Tasarımın, karmaşık olmayan ve seri üretime uygun bir yapıda olduğu belirtilmiştir. Tasarıma başlamadan önce piyasada mevcut diğer sabit GSM terminali cihazlarının fonksiyonel özellikleri araştırılıp en önemli ve çok kullanılan özellikleri tespit edilmiştir. Bu tez sadece teorik bir çalışma olmayıp, seri üretimi gerçekleştirilerek piyasada yerini almıştır. INTRODUCTION Thesis Problem Thesis Outline BACKGROUND What is GSM Technology?
