Expert Profile: Mark C J Posen

Expertise:  I am happy to answer questions of a technical and regulatory nature in the area of radiocommunications and satellite communications. I am best able to answer questions about systems and technology and less able to respond to questions about specific hardware and equipment setup and installation, but I'm happy to try and address any question put my way. My main areas of expertise are link analysis (link budgets, performance, Eb/No, capacity), interference analysis (C/I, protection ratios, interference avoidance), spectrum management (frequency coordination, inter-system sharing), Radio Regulation (ITU, ITU-R) and radio and satellite technologies and trends.

Experience in the area
I have worked as a radio and satellite communications engineer at a professional level since 1983. Since 1990, as Managing Director of RPC Telecommunications Limited, I have operated a private satellite and radio communications consultancy and have provided technical support to many satellite operators and national governments.
