Ανάλυση αγοράς τηλεπικοινωνιών, τεχνολογιών LTE και WiMAX και τεχνοοικονομική ανάλυση WiMAX δικτύων

Abstract

This thesis defines the telecommunications industry by making a historical overview as well as placing categories in their market. The gradual liberalization and the ever-increasing demand for telecommunications services have a positive impact on market development. Telecommunications have been and still are one of the main sectors that significantly boost the economy and directly affect the socio-cultural level of the population. It goes back from the 19th century telegraph to the optical fibers of the 21st century. As regards the categories of telecommunications market, these are defined in three categories: fixed telephony, mobile telephony and internet. Furthermore is a breakdown of the market for electronic communications worldwide, where there is a continuous growth of the information and communications technology industry as everyday life is increasingly connected to the digital age. A more in-depth analysis is made for Europe and Greece where the equipment market as well as future investments are examined in more detail. Finally, Greece is compared to the rest of Europe in the main factors of telecommunications services. The next chapter deals with the architecture and protocols of LTE where there has been continuous evolution over the last years with 1st , 2nd , 3rd and 4th generation networks. WiMAX technology is also analyzed with emphasis on protocols and key features. The last and most important section provides a strategic overview of WiMAX techno-economic analysis that is designed to assist a strategic planning team in developing viable business plan in Greece. The topic was covered in as wide a range as possible and with the most reliable data possible, this is because it requires consideration of many different parameters both in the technological requirements for the implementation of the program and in the financial. More specifically for the implementation of the project the main features, several technical information from a business perspective and the frequency bands of WiMAX technology have been considered. The economic analysis is done with the best possible approach as the economic environment of the industry and the financial situation in general are analyzed. After identifying factors such as costing, operating and capital expenditure, the most important financial indicators (KPIS) are analyzed to justify project approval or rejection.
