Nortel* [NYSE/TSX: NT] has successfully achieved the industry's first simultaneous uplink and downlink high-speed wireless calls between two mobile devices at uplink speeds four times faster than current UMTS services.
Nortel's demonstration - planned to be repeated at next week's 3GSM World Congress in Barcelona -- uses Nortel's commercial UMTS Base Transceiver Station and Aeroflex's TM500 handset simulator to exchange VOIP, videos and files at uplink speeds of 1.4 Mbps.
