SWINDON, U.K.-Motorola Inc. said it achieved the world’s first voice call over Global System for Mobile communications connected Internet Protocol technology.
Motorola gave the demonstration at a conference in London, attended by 180 GSM network operators from 75 countries. The first test call made by Motorola’s Network Solutions Sector was made from Motorola’s worldwide GSM headquarters in Swindon, U.K., to a research and development center in Chicago, using Motorla’s existing data intranet. The IP backhaul network was used to transmit both GSM signalling and voice packets within the GSM base station subsystem.
