Lucent introduces new flagship CDMA base station for 3G CDMA and
UMTS networks
December 10, 2002
Lucent Technologies today introduced the Lucent Flexent Modular
Cell 4.0 -- its new flagship CDMA base station. The product is part
of Lucent's Flexent OneBTS family of base stations, built using
a one-of-a-kind digital platform for 3G spread-spectrum technologies.
Verizon Wireless is one of the first customers to receive shipments
of the new product.
The Modular Cell 4.0 is the highest-capacity base station ever
introduced by Lucent, and more than 70 percent of its hardware is
common to Lucent's 3G UMTS base stations. Service providers can
upgrade the system to utilize innovative Bell-Labs developed technologies,
such as intelligent antennas and BLAST multiple input/multiple output
(MIMO) technology, which can further boost capacity to accommodate
the growing demand for mobile high-speed data services.
Verizon Wireless will test the Modular Cell 4.0 in Connecticut
and Florida in a live commercial network environment.
This base station platform's design affords mobile operators with
several significant benefits. It can incorporate power distribution
and battery back-up within the base station, reducing the size of
the cell site equipment footprint by 33 percent, and can yield a
12 percent savings in power consumption in a wide variety of deployment
scenarios over previous versions of the product.
Additionally, the Modular Cell 4.0 has OA&M (operations, administration
and management) feature improvements that reduce maintenance time
when components are replaced or when new installations and carrier
additions are made. It also improves backhaul efficiency, which
can help mobile operators reduce operating expenses.
The Flexent OneBTS digital radio shelf in the Modular Cell 4.0
protects a service provider's network investment because it can
support new technologies, via field upgrade kits, including:
* dual band capabilities -- base station can support both 850 and
1900 MHz spectrum in the same cabinet;
* mixed mode capabilities -- base station can support both 3G CDMA2000(TM)
and UMTS in the same cabinet;
* transmit diversity -- enhancement that can provide increased voice
and data capacity whether mobile operator's customer base consists
of 2G CDMA or 3G CDMA2000 users, or a mix of both;
* intelligent antennas -- advanced antenna and digital processing
technology that further enhances 2G and 3G voice and data capacity
and coverage;
* BLAST -- MIMO technology that uses multiple antennas at base station
to send and receive wireless signals to mobile devices with multiple
antennas, which can greatly increase capacity, coverage and speed
at which data is transmitted.
Field technicians can make these upgrades to the system without
having to remove it from its deployed location.
The Modular Cell 4.0 is available in both indoor and outdoor versions
and can support cdmaOne, CDMA2000 1X voice and data and CDMA2000
1xEV-DO in 1900 and 850 MHz spectrum. International indoor and outdoor
versions for 850 MHz also are available. With minimal modifications,
it also can be built to support other radio frequencies at a customer's
request.
