Italy’s contribution to the emerging digital mobile system extended from the behaviour of radio signals to the way speech would be encoded. This annex describes work by CSELT and SIP on propagation, modulation, speech coding and system simulation. It proposes laboratory equipment and field trials, with some hardware expected during the first quarter of 1986. Unlike a finished specification, the programme exposes the questions researchers still needed to resolve. Read beside the Franco-German annex, it reveals the different emphases within the partnership and the practical effort required to turn a shared ambition into a system that could work in real conditions.

An authoritative record of the people, decisions, technologies, documents and designs behind the mobile revolution.
