AbstractThe market is rapidly advancing toward 4G mobile communications and ubiquitous broadband. Today, operators

are in an excellent position to take advantage o both today’s widely-deployed WiMAX and emerging LTE

(Long-Term Evolution) standards in order to leverage the power o both and deliver anywhere, anytime wireless

broadband communications with a rich ecosystem and uncompromising economies o scale.

WiMAX 802.16e, with a dened roadmap to 802.16m, and LTE Rev.8, with a dened roadmap to LTE Rev.10,

deliver very similar perormance. A multi-technology, WiMAX/LTE approach delivers protability and fexibility

to meet current demand, and empowers operators to migrate to uture technologies while protecting their

investment.

This paper provides a high level overview o WiMAX and LTE and their evolution, as well as possible transition

and coexistence scenarios.

IntroductionThe drive toward 4G mobile communications is progressing ull speed ahead. The dizzying pace o growth in

mobile data usage and new applications demands that solutions be deployed to meet today’s demand while work

on new standards progresses.

4G solutions that deliver truly ubiquitous broadband will change the way many industries operate. Public utilities,

smart grids, oil and gas, and video surveillance are just a ew examples. Operators are in an excellent position to

take advantage o the current state o the industry to establish 4G services today, enjoy a return on investment,

and position themselves to take advantage o uture technologies and platorms.

Operators that embrace both widely-deployed WiMAX and emerging LTE will be uniquely positioned to leverage

the power o both and deliver anywhere, anytime wireless broadband communications with a rich ecosystem and

uncompromising economies o scale.

The 4G PromiseWiMAX and LTE are the two principal 4G mobile broadband technologies and research indicates that they will

remain in the oreront or the next ive to ten years. WiMAX enables new revenue generating applications

previously reserved to fixed line broadband. Both are all-IP, integrating mobile broadband with IP networking, and

both oer an ecosystem or networks, devices and applications. Equipped with an arsenal that includes today’s

WiMAX and a clear migration path to LTE, operators will gain a valuable competitive edge and gain market share

by taking advantage o access to broadband spectrum and be early to penetrate wireless broadband markets.

The Power of WiMAX and LTE• The undisputed principal mobile broadband platorms to be deployed over the next ten years

• Both are all-IP

• Both use OFDM air interace

• Current availability o market-tested and proven delivery o WiMAX services and applications

• Available to be operated in licensed spectrums and both address globally available bands

WiMAX and LTE

For carriers looking at both the short and long term gains, the “WiMAX vs. LTE” question is short-sighted. Andbased on recent market trends and research, it is a moot point. It is clear that both WiMAX and LTE will be widely

deployed. With the ocus on delivering services and applications that exceed the customer expectations, the

question is how to optimize and exploit both to deliver on the 4G promise and meet growing demand.

A multi-technology approach is optimal and an extremely viable way or operators to grow their businesses –

today and tomorrow. A multi-technology approach allows carriers to take more variables into consideration and

turn them into opportunities. These include the environment topography, such as urban or rural, and the type

o applications deployed. A dual approach lets carriers select the most suitable solution and technology or each

situation, and as a result, be prepared to overcome challenges in a more broad range o scenarios. For instance,

WiMAX’s lower cost o ownership, especially its cost eicient spectrum and IPR, and attractive time-to-market

allows or more Greenield operators to enter markets that were previously out o reach.

In all likelihood, when TD-LTE matures, it may be a compelling alternative for operators who have a large percentage

o mobile subscribers. Its ecosystem is expected to oer a large selection o handheld devices and avorable

conditions or roaming. WiMAX will continue to be the preerred choice or ixed/nomadic deployments and or

rural – suburban environments. In any case it is clearly not advisable to transition before the ecosystem fully matures.

The Drill-Down on Both Technologies

I we take a close look, we see that the dierences in perormance between the two technologies are minimal.This becomes even more evident i we analyze the unique advantages o both technologies; each leverages the

advantages o the other.

In terms of economies of scale, the strong market adoption rate of both WiMAX 802.16e-2005 and LTE delivers the

volume needed to make them both economically viable. Today, WiMAX enjoys the beneits o commitments with

major chipset manuacturers, and the market has a strong embedded base o WiMAX-enabled devices. Research

indicates that both WiMAX 802.16e-2005 and LTE will have rich device ecosystems based on standards-based

designs, cooperation with chipset manuacturers, and the interest o developer communities and manuacturers

o consumer electronics.

And o course, perormance is a crucial actor. WiMAX 802.16e, with a deined roadmap to 802.16m, will deliver

similar perormance to LTE Rev.10. Both approach the maximum spectral eiciencies o approximately 6 bits/Hz.

Today, operators are delivering in excess o 3.5 bits/Hz. with 802.16e. Next on the WiMAX roadmap, and already

proven in ield tests, 802.16m, will deliver over 5.0 bits/Hz., greater than 100 Mbps per sector or a 20 MHz

channel – and similar to the promise o LTE.

On the technology side, both are based on all-IP network architecture. This means reduced network complexity,

aster handovers, lexible service delivery and all-important scalability. Interoperability with existing wireless

technologies is o course, essential, and both WiMAX and LTE are seamlessly integrated with these platorms.

The multi-antenna techniques used on both overcome all types o deployment challenges, such as intererence,

high-speed mobility and more. Spectral holdings are also a key actor, and early evidence indicates that operators

will need both WiMAX and LTE to cover both TDD and FDD.

Spectrum Availability ConsiderationsRadio requency is a valuable and inite resource, and today it is diicult to meet demand. The need or spectrum

is being driven by the convenience and high use of mobile communications and the need for increased penetration

combined with improved perormance and the alling costs o wireless devices and services. Existing and new

mobile broadband networks deliver a highly compelling user experience by allowing multimedia applications

anywhere and are quickly consuming current spectrum allocations

FDD is generally more expensive and is traditionally owned by cellular operators. TDD is less expensive and

traditionally owned by broadband service providers and Greenelds. In the past, LTE was dened as FDD and

WiMAX as TDD. The strong interest in China or TDD helped advance the TD-LTE standard, which can use the

same spectrum bands allocated to WiMAX.

LTE has requencies allocated in the 700MHz, 2.3 and 2.5 GHz bands. WiMAX has requencies allocated in the

2.3, 2.5 and 3.5 GHz bands. So operators who own spectrum in the 3.5 GHz band have to deploy WiMAX and

only those who own 2.3-2.5 GHz TDD have the choice between the two technologies

Eventually, operators will need all available spectrum to meet the high demands o data services. The simple

choice between the FDD or TDD spectrum will simply not be enough. A combination o the two will be the only

answer.

Focus on WiMAX

The WiMAX industry has clearly passed its infection point, and oers a very competitive and broad end userdevice portolio with attractive price levels. There are literally hundreds o types o devices, USBs, laptops,

residential gateways, and handheld devices. This positions WiMAX as an operative and mature broadband

wireless solution or operators with licensed TDD spectrum (2.x and 3.x GHz).

Recent Inonetics market analysis indicates that the WiMAX industry reached a market level o $1.5 million TAM

(Total Addressable Market) in 2009 and will continue to grow, reaching an estimated $3 million in 2012 with an

annual CAGR o 24%.

Focus on LTEThe LTE industry is being targeted toward the evolution o 3GPP operators, with initial deployments in 2010-11.

In general, the LTE industry is emerging along two paths.

FDD LTE

FDD LTE is being primarily driven by Verizon in the U.S. on the 700 MHz spectrum, and NTT with KDDI in Japan

on 1.5 GHz. The major ocus is deploying 3GPP Rel. 8 in “hot areas,” which are data-centric, while voice will

run on existing 3G networks. LTE Rel. 8 is equivalent to WiMAX 16e in terms o capabilities, but lacks voice

support and other services which WiMAX 16e enables, such as a retail model, L2VPN and more. LTE Advanced

(Rel. 10) is equivalent to WiMAX 16m in terms o capabilities. LTE-A (Rel. 10) commercial deployments are

expected to be available ater 2013 or 2014 and are primarily driven by much higher capacity and support

legacy 3GPP services, such as voice and SMS.

TD-LTE

Mainly driven by the Chinese market on the 2.6 or 2.3 GHz spectrum, realistic timelines or commercial

deployments are expected to begin in 2012. TD-LTE is a primary alternative or WiMAX operators, who own

TDD spectrum in 2.x GHz. Current research indicates that it is reasonable to assume that TD-LTE will become

an attractive alternative to current WiMAX operators not beore 2013 or 2014. It is expected to present a

competitive end device ecosystem to WiMAX driven by volume rom the Chinese market.

4G Action PlanSo what’s the action plan? Clearly, the answer is not to rest idly on spectrum holdings. To achieve and maintain

a competitive edge, action in the 4G landscape needs to be taken today. That means deploying tried and true,

open standard WiMAX platorms, with proven devices, applications and rich ecosystem. WiMAX lowers cost

o ownership, especially with its cost ecient spectrum and IPR. The rapid time-to-market allows or more

Greeneld operators to penetrate new markets.

WiMAX is, and will continue to be, relevant or 4G wireless broadband due to:

•Maturity

•Availability

•Vibrantecosystem,includingdevices

•LowIntellectualPropertyRight(IPR)costs

•Soliddevelopmentroadmap

RAN migration costs and complexity can be signicantly reduced by sotware only upgrades like Alvarion’s SDR

(Sotware Dened Radio) and the ability to support multiple air interaces (LTE and WiMAX overlay).

Possible Scenarios

No Transition

Operator may choose to remain with WiMAX and orgo LTE entirely. This may be a worthwhile alternative or

regional WiMAX operators ocused on xed/nomadic services, or targeted communities that do not have the

wide area coverage to promote mobile access to customers or roamers.

Coexistence

Roll out an LTE network to complement existing WiMAX networks leaving both active. This allows operators

to provide bundled services and dual-mode devices to help draw more subscribers. This approach also requires

adequate spectrum, as well as nancial resources to operate two networks concurrently and over the long term.

Overlay

Operator gradually rolls out LTE and migrates WiMAX subscribers to LTE with WiMAX and LTE operating in

parallel. This oers more fexibility than a total replacement, as well as reducing the risk o service disruption,

but requires access to adequate spectrum to handle both networks concurrently.

Total Replacement

Operator upgrades all users simultaneously. This may be the only option or operators with limited spectrum

allocations since the cost o support or a network that combines WiMAX and LTE, even or a limited time, will

be prohibitive. This option is most eective i a base station sotware upgrade is available, and subscribers have

multimode devices supporting both WiMAX and LTE. I devices must be replaced and hardware changes are

required, this type o transition will in all likelihood cause service disruption.




11

Moving Forward

WiMAX will continue to strengthen and grow while the other technologies mature. WiMAX oers a compelling

migration path and the prospects or TD-LTE are very positive.

Operators need the fexibility to make the transition when they need it, at their own pace, without disrupting

service. Thereore, it is to their advantage to continue to expand existing WiMAX networks, ensuring continuity

o service and portability, even i, and when, they decide to make transition to TD-LTE.

There is no doubt that both technologies will coexist. They are being driven rom two separate ecosystems,

and only both together will be able to meet the demand or broadband services that continues to grow at an

electriying pace. So or operators looking or a platorm that meets current requirements, with the fexibility to

accommodate uture technologies and protect their investment, the answer isn’t WiMAX or LTE. The answer is

both.

“It’s about the addition of LTE to the mix, and not a switch. If LTE does

take off, and there are devices with LTE and without WiMAX, we want

to be able to service those customers too.”
