Nortel Networks and Vodafone in Spain (formerly Airtel Movil) have successfully completed live international roaming calls using the UMTS
(Universal Mobile Telecommunications System) 3GPP (Third Generation Partnership Project) wireless standard, demonstrating Nortel Networks
commitment to deliver interoperable UMTS networks in line with customer deployment schedules and market requirements.
The live voice calls were completed between Madrid and Tokyo using Vodafone's Spanish UMTS network and the UMTS network of its Japanese sister company, J-Phone. Calls from Spain were made with a QUALCOMM MSM5200 chipset-based handset using SIM technology from the J-Phone network, and completed over Vodafone's commercial UMTS network in Spain, which was deployed and installed by Nortel Networks.
"Our announcement of the World's first 3G roaming call marks a significant milestone in the development of Vodafone's future multimedia services and the roll-out of 3G mobile," explained John de Wit, Chief Executive of
Vodafone in Spain.
"We are strongly committed to supporting Vodafone in deploying its UMTS networks throughout Europe, and to allowing Vodafone customers to benefit
from the promise of 3G UMTS as a universal standard delivering seamless, 'always on' services regardless of location," said Pascal Debon, president, Wireless Networks, Nortel Networks.
The global roaming calls followed a series of key milestones achieved by Nortel Networks with Vodafone in Spain earlier this year, including
successful deployment nationwide, and testing of commercial equipment involving voice calls in eight Spanish regions including the Canary Islands.
Nortel Networks is currently deploying and testing UMTS networks for Vodafone affiliates Omnitel in Italy and Vodafone Portugal (formerly
Telecel), in addition to Vodafone in Spain.
