Decio Ongaro, senior vice-president for Italtel SpA’s mobile radio unit, gave a technical presentation on Digital European Cordless Telephony at Busacca & Associati’s Mobicom’96 conference last month in Milan, in an apparent effort to defuse the controversy over Telecom Italia SpA’s experimentation with the technology: To continue current levels of [mobile telephone usage] growth, we have to increase the network’s capacity, Ongaro said. Digital Cordless would provide capacity of over 20 million, against Personal Communications Network’s 10 million. But then he noted its limitations – It functions perfectly as long as the calls are coming from the same central switch, he said, but when the central switches are far apart or you get up to a speed of 25 to 30 miles an hour, you get a problem of synchronization.
