Telecom Lead America: Nokia Siemens has launched two new
solutions — Energy Efficient Coverage (EEC) and Configurable Carrier Bandwidth
for WCDMA — that allow operators to offer mobile broadband more
effectively with their existing spectrum.
They form part of the company’s Liquid Radio GSM
software suite.
EEC enables existing GSM spectrum to support up to double
the amount of traffic. Alternatively, it can achieve the same GSM performance
using less spectrum, thus freeing up more frequencies forWCDMA re-farming. In
addition it can significantly improve network coverage.
Configurable Carrier Bandwidth for WCDMA allows
WCDMA carrier bandwidth to be set in software configurable steps of 200 kHz
from the very narrow 3.8 MHz up to 4.2 MHz, depending on an operator’s
spectrum. It gives operators full flexibility to allocate more GSM spectrum to
WCDMA as it becomes available. The feature allows co-location of GSM and WCDMA
on the same frequency band for operators with extremely limited spectrum.
The two new software features will be available
commercially in the second half of 2012.
Mobile spectrum is scarce, and operators want to
maximize the GSM spectrum they can re-farm to WCDMA and LTE. Our software suite
addresses this challenge. Operators can re-farm using much narrower spectrum
than before, deliver GSM and WCDMA with 30% less spectrum, and also lower total
cost of ownership by 20 percent. Moreover, they can deliver a vastly improved
user experience, and potentially attract more customers to increase revenues,”
said Dhruv Khanna, head of sales development for Mobile Broadband, North
America, Nokia Siemens Networks.
Operators can deploy the features with Nokia Siemens
Networks’ Single RAN platform via a simple software upgrade to evolve
their networks smoothly, and cost-efficiently manage the huge growth in mobile
broadband traffic.
To help operators increase network capacity and improve
network performance, Nokia Siemens Networks offers planning and implementation
services for WCDMA and LTE re-farming. By supporting more than 65 percent of
commercial WCDMA and over 50 percent of commercial LTE re-farming networks, the
company is the leader in spectrum re-farming services.
