Optimize Wireless Networks for Data2
End users around the world are quickly adopting the
blended lifestyle made possible by accessible and afford-
able communications that allow them to blur the lines
between work, home life and entertainment. To support
that lifestyle, end users are subscribing to services they
can easily adapt and personalize to their needs on
whatever communications device they choose.
Wireless broadband data services are an important part
of the blended lifestyle equation. They allow end users
to not only place calls and access the Internet with
their wireless devices, but also connect with their office
networks over secure links, download music and videos,
and take advantage of a host of location-based services
that give them access to home, work and entertainment
from anywhere and at any time.
Fueling this evolution in communication are new
IP-enabled cell phones and laptop air cards that,
when combined with new data pricing plans, have
made using wireless broadband data services more
affordable. As a result, wireless service providers
worldwide are beginning to experience measurable
subscriber uptake for these services. The wireless IP
transformation is here and now.
But while all this is good news from a business perspec-
tive, the increase in data traffic is creating concerns about
how IP packet data affects wireless networks. Since IP
applications were not designed for transmission over a
wireless infrastructure, it is no surprise that some of these
applications consume significant amounts of resources
in the wireless network. In addition to bandwidth, these
applications consume signaling, radio frequency (RF)
channels, airtime, and backhaul resources. The perform-
ance of wireless IP networks is intimately coupled to the
types of applications the network transports, and in a
complex way.
To accommodate the IP load, and enable resilient and robust
delivery of emerging applications, wireless service providers
need complete visibility of how every behavior and flow —
resolved to individual devices and servers — places load
on the network. This is a paradigm shift in how IP networks
are currently built. This new visibility means the service
provider can effectively optimize their wireless networks
to deliver the continuously evolving list of applications.
Identify Resour e Usage
and Manage the Network
The Alcatel-Lucent 9900 Wireless Network Guardian
(WNG) offers powerful capabilities for monitoring
2.5G, 3G and 4G wireless data networks. It identifies
wireless network resource usage and allows you to better
manage network performance. And it allows you to pro-
tect your networks from degraded performance and outages
that can arise from transmitting wireless-unfriendly IP
traffic.
This advanced wireless network monitoring product
provides detailed information about how every subscriber,
application, server, and flow creates actual load on your
wireless data network, and delivers alerts about any
behaviors that have an anomalous impact on network
performance and capacity.

Improve Network Performan e
All applications that run on IP net-
works are traditionally reduced to a
single dimension — volume (or band-
width). Quite simply, “data is data”.
As wireless networks become more
IP-like — both in terms of technol-
ogy and how subscribers use those
networks — experience suggests we
can design, engineer, optimize, ma-
nage, and price the networks by this
dimension, bandwidth.
This operating principle is funda-
mentally unsound in wireless IP
networks. Two applications that
may consume exactly the same
bandwidth may have widely dispro-
portionate impacts on other critical
resources in the network, such as
airtime (Figure 2).
Every IP application that transmits
over the wireless data network
consumes many different resources in
the network. Service providers need
to still scale applications by band-
width, but must also scale other
resources, such as radio-access
airtime, device-network signaling
and base station channels.
Data is no longer “just data” on
wireless IP networks. And that
means to properly design, engineer,
optimize, manage, price, and
ultimately differentiate NGN
Wireless IP networks, service
providers must have never-before-
required visibility into how packets
and flows impact every constrained
resource in the wireless network —
from the packet core all the way
down into the radio access network.
The Alcatel-Lucent 9900 WNG is
the first product to market in a new
product category, which enables
wireless operators to operationally
connect IP-layer behaviors to
Wireless-layer impacts, and to opti-
mize, manage, and build out their
networks accordingly
In addition, an optional managed
service component can relieve your
network operations personnel of the
burden of monitoring the network
for performance-impacting events.
This helps you defer or postpone
costs associated with training and
developing the subject matter
experts required to leverage the
forensic/root-cause analysis capa-
bility of the Alcatel-Lucent 9900
WNG and propose/implement
mitigation policies.

Streamline Engineering
and Planning
Network planning is based on aver-
age models of subscriber usage during
busy hours. It assumes average load
characteristics per subscriber. But
each device, application, and sub-
scriber can have highly differing
and unpredictable impacts on the
network.
The Alcatel-Lucent 9900 WNG
helps engineering and planning
teams see exactly how subscribers
in any given region are using the
network, so that the appropriate
resources can be added or real-
located to accommodate the
measured and specific subscriber
activities.
Moreover, by providing detailed
network usage information, the
Alcatel-Lucent 9900 WNG helps
engineering and planning teams
understand actual usage patterns
and perform a reasonable trending
analysis that can be used to guard
the network against any negative
impacts caused by customer
concentration on certain
applications.
Manage Se urity
Wireless security requirements are
more challenging than wireline
security because:
• Attacks can be waged on the net-
work using extremely low volume
traffic that masks as every day
traffic (for example, without
packet-specific signatures)
• Attacks can come from within
the wireless data network and
can leverage mobile-to-mobile
communications without crossing
a peering point (where IP security
tools are often deployed)
• The IP address in the mobile
world easily and constantly
changes, so tracking potential
attackers is a multi-step challenge
The Alcatel-Lucent 9900 WNG
provides network security teams
with tools specifically designed for
wireless data networks that can help
identify and manage threats and
denials of service.
Develop Targeted Marketing
Beyond network operation, planning
and security, the Alcatel-Lucent 9900
WNG can also enhance marketing
efforts that directly contribute to
subscriber retention and reduce churn.
With the detailed network perform-
ance and subscriber information
available from the Alcatel-Lucent
9900 WNG, marketing teams can
get a better understanding of how
much it costs the network to support
every subscriber, every application,
and every device type. With this
information, marketers can
determine an R I for each existing
and new service, based not only on
the cost of the subsidized device or
application royalties (if customer-
hosted), but also the fundamental
cost to the network.
As a result, you can choose devices
and applications that enable max-
imum profitability for your market.
