Meeting the fast-paced challenges

of universal broadband

WiMAX offers operators the opportunity to capture the three main pieces

of the universal broadband industry trend in a single technology, regardless

of whether they are building on an existing business and subscriber base, or

starting from scratch:

•Ubiquity – untethering the broadband experience from ﬁxed locations,

for access anywhere

•Always on – continuous broadband availability from the moment

the end user wakes in the morning until they retire at night

•All-IP – delivery of broadband over 100 percent IP networks offering

optimizedeconomics,simplicityandperformance

However, in deploying WiMAX today, operators ﬁnd themselves in unfamiliar

territory.Theradiotechnologyisnewsostandardproceduresarenotestablished,

and even for experienced mobile service providers, the IP networking aspect is

awholenewworld.Thereisanelevatedneedforassurancesofafast,ready-to-

market approach, reduced risk and reduced network complexity — both for the

initialandsubsequentstepsinthebusiness.Signicantmarketchangesmust

be anticipated, as the arrival of mobile WiMAX devices and handhelds will soon

begin to change users’ needs from more classical PC-oriented services to more

personalizedones.Therapidramp-upinsubscribersandtrafcwillalsoputpres-

sure on service providers to maintain consistent, high-quality service delivery.

The requirements for launching a sustainable

WiMAX business play out in three steps:

Step 1: Cost-effective coverage and capacity –

Theinitialneedistorollout

high-speed Internet and VoIP services quickly and economically, with a high

standardofQoSandqualityofexperience(QoE)forendusers.

Step 2: Sustainable expansion –

In the next phase, as your subscriber base and

resulting network trafﬁc grows rapidly, you must maintain this outstanding

qualityofexperienceandbeabletoscalethenetworkatoptimizedcost.

Step 3: Differentiated services that grow revenue –

Finally, your competitive need

willbetodifferentiateyourserviceoffer,withpersonalizedmobilemultimedia

applications that enable you to leverage the broadband connection and move

up the value chain. Not only can these steps generate new revenue opportuni-

ties, but also allow you to take advantage of new business models.

Best-in-class WiMAX Rev-e

Alcatel-Lucent is the market leader

in WiMAX Rev-e access solutions

counting the number of commercial

network deployments and trials com-

pleted or underway worldwide. Our

hardened,industrializedbasestation

portfolio is in mass production, sup-

porting all frequencies — and strictly

in compliance with Rev-e standards.

Advanced antenna technology –

Alcatel-Lucent radio solutions incor-

porate beam forming and MIMO to

helpoptimizecoverageandcapacity.

Byreducinginterferenceandincreasing

spectral efﬁciency, beam forming offers

stable performance in all environments,

and coverage improvements can reduce

the number of sites required to estab-

lish coverage by up to 40 percent —

leading to signiﬁcant reductions in

bothCAPEXandOPEX.Combined

with MIMO, capacity increases of

more than 40 percent become pos-

sible — a huge help as networks

dimension upwards.
