Whom do the SGs comprise? Estimated that persons from the ITU membership attend SGs and their subordinate groups on a regular basis
What do the SGs actually do? The fist major task is to prepare the technical bases for WRCs; conferences require technical information, data and advice on which to base regulatory decisions and it is the SGs who provide such material for the conferences to consider in their deliberations
Secondly, the SGs prepare Recommendations – those authoritative texts which provide technical information and guidance on radiocommunication systems, their operation and the associated spectrum issues
Thirdly, put together handbooks – increasing interest over the past decade or so - particularly as tutorial aids for developing countries.
