The forthcoming Communications 90 exhibition in Birmingham is set to be the largest ever staging of the long-running event, claimed show organisers Reed Exhibitions at a review given this week: major names such as France Telecom, Cellnet, Racal, Mitel Telecom, Ferranti and Philips will be exhibiting, and Reed says it has devised mobile and data telecommunications trails to help visitors interested in those areas to move between the relevant stands; a conference, dealing with business-to-business and business-to-user telecommunications issues, is being organised for the first three days of the show, which is set for April 24 to 27 at Birmingham’s National Exhibition Centre.
