Lucent unveils compact cdma2000 base station
November 26, 2002
Lucent Technologies today introduced a 3G CDMA2000 base station
that, because of its compact design and distributed architecture,
offers the flexibility needed to meet a variety of deployment needs
and coverage challenges for mobile operators employing 1900 MHz
or PCS spectrum. Sprint has deployed this system, the Lucent Flexent
CDMA Enhanced Distributed Base Station (CEDBS).
This platform can be used to simplify deployment in areas difficult
to cover with traditional products, fill in coverage gaps, or provide
additional capacity in high-traffic areas such as highways, major
cities or in buildings. Because it has a small "footprint," and
can be mounted on telephone poles, walls and roofs of buildings,
the base station can substantially reduce cell site acquisition
costs.
"The architecture and design of this system will help us provide
coverage in areas where it is difficult to deploy more traditional
base stations," said Mike Hennigan, vice president of site development,
PCS division of Sprint. "In some instances, we anticipate deploying
this base station on utility poles to help us meet stringent zoning
requirements."
The Flexent CEDBS's unique design enables mobile operators to deploy
the radio frequency units (RFUs), the components of a base station
that send and receive radio signals, and power system separately
from the base band units (BBUs), the components of a base station
that process and send the radio signals to and from the mobile switching
center. The RFUs and BBUs can be connected by a customer-provided
single-mode fiber cable at distances of up to 15 miles.
"This system is ideal for large mobile operators that need to expand
their existing network coverage, particularly in areas with lower
capacity needs, or where site acquisition poses significant challenges,"
said Mike Iandolo, vice president of CDMA product management and
marketing, Lucent Mobility Solutions Group. "Additionally, its flexibility
and low-cost makes it suitable for small-to-medium size mobile operators
deploying new networks."
The Flexent CEDBS is a three-sector base station with one carrier
that supports cdmaOne and CDMA2000 1X voice and data services.
