Nortel, QUALCOMM and Orange have successfully completed UMTS and HSDPA calls in the 900 MHz band, a spectrum capable of delivering wireless broadband such as mobile TV, video-on-demand, video telephony and DSL-like services to rural areas.
W-CDMA (UMTS) in the 900 MHz band is a cost effective way to deliver nationwide high-speed wireless coverage. It achieves a 60 percent reduction in cell sites required to serve rural areas and delivers improved Quality of Service in urban areas by enhancing in-building penetration by 25 percent.
The category 6 HSDPA calls, using the 16 QAM Modulation and reaching 3.6Mbps data rate, were completed using Nortel's commercial infrastructure equipment, mobile handsets based on QUALCOMM's Mobile Station Modem MSM6280 chipset solution and Orange's 900 MHz spectrum.
"UMTS in the 900 MHz band is a complementary solution to existing 3G services that will enable Orange to provide high speed wireless Internet to both rural and urban areas of our different geographies," said Vivek Badrinath, Executive Vice President, Products, Technology and Innovation, Orange Group.
Nortel's innovations in spectral efficiency are the key enablers to liberate spectrum in the 900 MHz band, providing wireless operators with the capability to deploy W-CDMA in that band. The implementation of UMTS 900 is compatible with widely deployed Node B hardware for simplified integration. QUALCOMM's Mobile Station Modem solutions for HSDPA were the first in the world to be commercially available, and data rates of up to 7.2 Mbps are supported by the company's HSDPA portfolio. Nortel, Qualcomm and Orange plan to publicly demonstrate this capability during the 3GSM World Congress in Barcelona in February.
Nortel achieved the industry's first HSDPA mobile call in January 2005. Nortel and LGE completed the first live test calls using a commercial handset solution for HSDPA in March 2005. In June 2005, Nortel became the first wireless network supplier to complete the TL9000 registration standard for Quality Management System Requirements and Measurements across its HSDPA, UMTS and GSM wireless infrastructure solutions.
Nortel has worked with a number of wireless operators on HSDPA trials and deployments in 2005, including EDGE Wireless in the US, SKT and KTF in Korea, SOFTBANK Group's BB Mobile in Japan, mmO2, Orange (at 3GSM World Congress 2005 in Cannes, France), Vodafone (at CeBIT 2005 in Hanover, Germany), Partner Communications in Israel, and Mobilkom Austria.
