Nortel Networks, QUALCOMM Complete UMTS Calls Using 1900 MHz Radio Spectrum PDF Print E-mail
Thursday, 10 October 2002 and

Nortel Networks and QUALCOMM have completed the industry's first UMTS (Universal Mobile Telecommunications System) voice and data calls demonstrating mobility across commercial cell sites using live 1900 MHz radio spectrum, QUALCOMM chipsets in commercial-form-factor handsets, and a live, end-to-end 3GPP (Third Generation Partnership Project) UMTS network from Nortel Networks.
This is significant for North American GSM operators, who have spectrum available at 1900 MHZ but not at 2100 MHz. To date, U.S and Canadian regulatory bodies have not indicated when or if 2100 spectrum - traditionally used for UMTS (or W-CDMA) service elsewhere in the world - will be made available in North America.

Nortel Networks and QUALCOMM have demonstrated voice and data services at 1900 MHz with network-based circuit and packet handovers at data speeds of up to 384 kilobits per second (kbps). High-speed data can improve network capacity and quality of service for wireless data applications like multimedia messaging (MMS), e-mail, file transfers, and location-based services, as well as drive a new era of streaming video, video telephony, and other visual wireless services.

Migrating to Wireless Data Networks such as UMTS provides a highly cost-effective solution that will help GSM operators meet growing capacity demand and generate new revenues while improving end-user experiences with existing and emerging data services.

"The ability to offer UMTS services over the 1900 spectrum provides a very strategic and cost-effective migration option for North American GSM operators," said Mark Whitton, leader, Technology and Product Strategy, Wireless Networks, Nortel Networks. "This enables them to offer UMTS services without the immediate need for capital investment in 2100 spectrum."
