Shaanxi Telecom Great Wall, Nortel (Northern Telecom) Launch CDMA Network in Xian
BEIJING, Sept. 17 /PRNewswire/ -- Nortel (Northern Telecom) (NYSE: NT - news; TSE: NTL - news), continuing to build
on its worldwide CDMA leadership position, announced its part in one of the early commercial cdmaOne (IS-95 CDMA)
networks in China.
Shaanxi Telecom Great Wall has put into service one of the first CDMA networks in China. Nortel was responsible for
engineering, constructing and successfully testing the network in the ancient historic city of Xian. The launch of this CDMA
network builds on Nortel's continued experience in providing telecommunications solutions in China dating back to 1972 with
the delivery of transmission equipment.
In addition to passing a rigorous standardization and certification process that focused on Nortel's network performance,
features and capabilities and compliance to standards, testing was also recently completed in a successful effort to achieve
IS-41C networking with other Great Wall networks.
These accomplishments come less than a year after Nortel CDMA equipment was first delivered to China. Nortel was able to
successfully complete trials and testing within an extremely tight timeframe.
The Xian network has an initial capacity of 13,000 subscribers and extends to six regions outside the city. Additionally, Xian
subscribers can roam on CDMA networks in Beijing and Shanghai.
Nortel brings a number of unique capabilities to this CDMA launch including its unsurpassed receiver sensitivity and handoff
capabilities.
Nortel's base stations received the highest rating for receiver sensitivity by the State Radio Regulatory Commission. Nortel's
CDMA receiver sensitivity provides operators with a larger footprint and more efficient link budgets, which translate into saving
operation costs.
Nortel was the first to offer a six-way intelligent soft handoff, which allows calls to achieve faster, more reliable soft handoff
set-up, resulting in lower dropped call rates and excellent voice quality. Other networks are frequently limited to handing off
calls to three neighboring cell sites rather than Nortel's six.
Nortel's advanced power control algorithm furnishes operators with more control over network interference. This gives
operators more network capacity and helps to extend the battery life of a subscriber's mobile phone.
Nortel CDMA digital wireless networks are in service or under construction in more than 80 cities around the world, serving
more than a million subscribers. Nortel has shipped more than 5,000 base stations in 18 months.
