Abstract

Satellites for communications are today used for numerous applications which allow users to exchange information even in those scenarios where other technologies fail. On top of the typical broadcasting of TV and radio signals to multiple users, which represents their most familiar use, satellites provide today solutions for fulfilling the communication need in many other scenarios such as voice and data links for users onboard mobile platforms, emergency communication links for relief and recovery operations and access to the internet from areas not served by other terrestrial means. As satellite systems operate internationally, under the jurisdiction of treaties and international law, as well as internationally agreed standards, technical solutions must be adapted to political (and often inefficient) agreements. The aim of this course is to analyse the technical and regulatory framework modern satellite systems operate in.

Syllabus

• The international spectrum management:
• Identification, description and interdependencies of the international bodies involved in today’s international spectrum management and standardisation;
• How international spectrum and telecom regulations are developed and, as an example, description and interconnection of the ITU and European processes.
• The international status of the RF spectrum today:
• General overview of spectrum allocations and spectrum management;
• Technology solutions and proposals for a better use of this limited resource;
• Current practices for spectrum awards at national level and future trends.
• Communications via satellite – past, present and future:
• Type of satellite orbits and constellations: e.g. GSO, NGSO, Elliptical, Outer space; technical and market aspects; pros and cons;
• State of the art and distinction between satellite services;
• Description of the new future technologies for the provision of communication systems operating through satellite;
• Regulatory framework for satellite services.
• The spectrum management in the satellite industry:
• Identification and description of the relevant stakeholders: e.g. satellite operators, equipment manufacturers, types of users;
• Inter-operators coordination and notification under the ITU Radio Regulations;
• Other issues and challenges, e.g. coordination arc, protection criteria, sharing versus band segmentation.
