@vantage NB-880Think complete. Care for detail.Siemens Communications Mobile Networks
Powerhouse performance
in a persuasive package
The latest in a line of rugged, versatile
Siemens 3G W-CDMA FDD Macro Node B
offerings, the @vantage NB-880 is a pro-
duct of experience. A third generation
Node B, it brings tremendous benefits
to customers with its vastly enhanced
technology and the insight born of
countless deployments. Boasting twice
the capacity of its predecessor, the ultra
efficient @vantage NB-880 cuts energy
costs by 30 percent. Fully backward-
compatible with widespread @vantage
NB-44x modules and designed to sup-
port the @vantage NB-44x feature set,
the @vantage NB-880 incorporates the
latest features and technology. Best of
all, it is ready for emerging innovations
such as remote radio heads.
Spare capital and leavea small footprintThe @vantage NB-880 delivers the kind
of performance that can make OPEX
savings soar: Designed for ultra low
power consumption, it generates less
heat, sparing energy, resources and
overhead.
While the forerunner generation sup-
ported 500 voice channels, the new
@vantage NB-880 line doubles capacity
to 1,000.
The @vantage NB-880 reduces power
consumption by a third, saving operators
an impressive 30 percent in energy costs.
It uses digital signal processing algo-
rithms to boost the power amplifier’s
efficiency (realized in CAT). Hardware
modules are interchangeable with
@vantage NB-44x models, reducing
overhead for spares and logistics.
What’s more, a single software load is
able to update all different module types,
thereby significantly cutting the costs
of upgrading software and training staff.
And the @vantage NB-880 supports tried-
and-true features such as remote anten-
na down-tilt adjustment via Radio Com-
mander (RET), adding to the solution’s
convenience and manpower efficiency.
Geared for greatest flexibilityIts ability to cut CAPEX is equally impres-
sive. Offering all but unlimited scalabi-
lity, expandability and upgradeability,
these nodes provide a perfect fit for
every MNO, business plan and market
scenario.
A tall order to fill, the Node B family is
able to meet every expectation, from
single-carrier, single-sector configura-
tions (1/0/0) up to full-blown four-carrier,
three-sector configurations (4/4/4)
designed to deliver ultra high perfor-
mance. And with this remarkable degree
of flexibility, the @vantage NB-880 is the
perfect choice for rising to the demand-
ing challenges of mass rollout.
Here today, ready for tomorrowThird generation Node B architecture is
future-proof: Engineered specifically to
satisfy today’s demands, it is also pre-
pared for new services and applications
such as HSDPA, as well as other advances
the future will bring. Siemens charted an
evolution path from today’s @vantage
NB-880 to a full-fledged radio server on
the same hardware platform, with full
backwards compatibility to support in-
stalled nodes. Ready to handle heavy data
traffic and facilitate migration to HSDPA
(as @vantage NB-44x family), smart
antennas and IP, the Node B line safe-
guards MNOs’ investments for many
tomorrows to come.
Better, not bigger.

E1 up to 16
STM-1 up to 2
Physical & environmental
Dimensions (H x W x D) 1400 x 600 x 450 mm
Typical weight 130 kg
Typical power consumption 623 W
Operating temperature -5 °C ... 45 °C
HighlightsUp to 4/4/4 configuration and up to
1,000 gross voice channels in one
rack/shelf
Up to 80 W per sector / 80 W per cell
with optional TX diversity
RX diversity included; TX diversity
optional
Variable line interfaces enable opera-
tors to freely choose rollout capacity
and transmission features.
Line interface cards support trans-
mission features such as CES, IMA and
Fractional ATM to maximize capacity
and utilization of incumbents’ legacy
transmission networks.
Load-sharing among channel cards
minimizes downtime.
Small footprint -
just 1400 x 600 x 450 mm
Channel card handles both traffic and
common channels, considerably
enhancing baseband resources.
Channel bank for baseband capacity
ensures baseband resources are used
most efficiently. In addition, users in
Softer Handover do not require addi-
tional baseband resources.
Low-level TX spurious emission facili-
tates isolation in GSM BTS collocation
scenarios.
Optional remote electrical tilt reduces
interference and provides a redun-
dancy alternative.
