Analysis and comparison of leo and meo satellite networks

Abstract

Telecommunication market is based on a demand and supply of new more and more attractive services. Telecommunication companies develop and offer new reliable broadband multimedia and interactive services for users no matter they are fixed or mobile, situated in areas with or without high communication infrastructure or use a small handheld or desktop end terminal. In order to fulfill those requirements satellite systems are also incorporated in global communications systems. Last fifteen years are also characterised by the increased effort in a nongeostacionary satellite area. New satellite constellations on lower earth orbits have been proposed and developed. This paper is oriented in a comparison of satellite systems utilising low and medium Earth orbits. The comparison is realised based on delays of the packets transmitted over these systems.
