FOR RELEASE WEDNESDAY DECEMBER 18, 2002
New integrated circuit developed by Bell Labs' mobility team incorporates
intelligent antenna capabilities that support greater volumes of voice and data
traffic
MURRAY HILL, N.J. - Lucent Technologies today introduced a
capacity-increasing chip that will be integrated into its new flagship
third-generation (3G) CDMA2000™ base station unveiled last week, the Flexent®
Modular Cell 4.0, and future products in the Flexent® OneBTS™ family of base
stations. The "ASIC," or application-specific integrated circuit, was
developed by the mobility team in Lucent's Bell Laboratories and incorporates
intelligent antenna capabilities that enable these base stations to support
substantially greater volumes of voice and data traffic.
Mobile operators that deploy 3G CDMA2000 1X networks already can double voice
capacity over existing 2G CDMA (Code Division Multiple Access) networks.
Lucent's ASIC, which supports CDMA2000, also can deliver an additional two-fold
increase in capacity by utilizing the intelligent antenna feature. It also can
boost data capacity by more than 100 percent to accommodate the growing demand
for mobile high-speed data services, and this can increase overall data
throughput delivered directly to consumers.
"The development of this ASIC is another example of how we are leveraging
our spread-spectrum CDMA expertise to provide our customers with the most
advanced and cost-effective solutions," said Paul Mankiewich, CTO and chief
architect of Lucent's Mobility Solutions Group. "Mobile operators that
invest in the Modular Cell 4.0 and our future CDMA2000 base stations will be
able to manage the ever-increasing need for voice capacity, and growing demand
for mobile data services among businesses and consumers, for years to
come."
The Modular Cell 4.0 is "pre-wired" to support intelligent antenna
capabilities, which provides mobile operators with a simple and cost-effective
way to add capacity.
The mobility team overcame significant challenges to develop an integrated
solution that provides true per-user intelligent antenna processing. Without
per-user intelligent antenna processing, a base station's antennas produce a
wide-angle radio signal beam that transmits to all users in a given area.
However, with per-user intelligent antenna processing, the base station sends a
separate, dedicated, narrower beam to each active user, which adaptively
follows them as they move through the base station's coverage area.
Transmitting simultaneous, dedicated beams to each active user makes more
efficient use of spectrum and reduces interference, resulting in capacity
gains.
Lucent's intelligent antenna processing techniques also are applied to the
"reverse link," or the signal a base station receives from a mobile
device when a voice or data call is active. The combination of intelligent
antenna processing at the base station -- in both the signal transmission and
reception of signals from mobile devices -- makes the overall system capacity
gains possible.
Capacity and performance improvements from the Lucent intelligent antenna ASIC
can be realized whether a mobile operator's customer base consists of 2G CDMA
or 3G CDMA2000 users, or a mix of both, without the need for modifications to
today's 2G CDMA or 3G CDMA2000 cell phones or devices.
The high-density ASIC, which includes the intelligent antenna feature, will be
integrated into Lucent channel cards, which can be used to further enhance the
capacity of the Modular Cell 4.0, and future CDMA2000 base stations in the
OneBTS family.
The Modular Cell 4.0 is part of Lucent's Flexent® OneBTS™ family of base
stations, built using a one-of-a-kind digital platform for 3G technologies. The
product is the highest-capacity base station ever introduced by Lucent, and
nearly all of its hardware is common to Lucent's 3G UMTS (Universal Mobile
Telecommunications System) base stations.
Lucent's Mobility Solutions Group is a leading global provider of mobile
networking technologies, having deployed more than 70,000 spread-spectrum base
stations for mobile operators worldwide.
Lucent Technologies, headquartered in Murray Hill, N.J., USA, designs and
delivers networks for the world's largest communications service providers.
