Cellnet has increased its present supply contracts with Motorola’s UK cellular infrastructure division to include the supply of radio equipment for the operational phase of the pan-European Groupe Speciale Mobile digital cellular telephone network – the original contracts with Motorola were for the supply of GSM validation and pre-operation-al systems: Cellnet has also concluded an agreement with Nokia Oy for its ECR900 base stations, developed in conjunction with Alcatel and AEG, for the GSM system.
