Abstract
Profitability is the core of any business and impacts sustainability. The WiMAX industry is flourishing
worldwide but profitability remains at the horizons. There are many factors affecting this, includingmodem subsidies. In order to remain competitive against rival broadband technologies, WiMAX
Operators offer cheap packages and absorb heavy device subsidies which delays profitability.
This paper focuses on how cost-effective modems can help WiMAX Operators expedite profitability.
Though the current IEEE 802.16e advocates Mobile WiMAX, majority of the users, especially in
emerging markets rely on WiMAX as a fixed broadband network. In response to this pattern, the
industry is flooded with a variety of indoor (fixed) modems. Many of these modems are integrated
devices, combining WiFi, data and voice ports. However, very often these ports remain unutilized by
residential users and the excess ports merely contribute to more expensive modems.
This paper also gives a better understanding of usage patterns in both emerging and developed
markets. It helps WiMAX Operators realize that basic, economic modems are able to perfectly meet
user requirements without jeopardizing performance. As a result, WiMAX Operators gain from a
shorter profitability period while users enjoy quality broadband connectivity.

The Sunrise Industry Misses Its Cheese
Worldwide Interoperability for Microwave Access (WiMAX) has been gaining rapid global traction with 588 deployments
across 148 countries recorded as of April 2010. This wireless broadband technology is reputed to provide reliable,
secure and high quality broadband access for fixed and mobile users. Additionally, WiMAX has been built as an IP-based
network which gives it the edge in supporting bandwidth-heavy applications and user generated content (UGC) services.
These characteristics have positioned WiMAX as a saviour technology to combat network congestion due tooverwhelming data traffic and this technology is viewed as the receiving network to support data offloading.
On another note, WiMAXs business model is yet to be proven profitable. The only consolation is that several leading
WiMAX Operators such as Yota and Globe have reached break-even points and are hoping to turn EBITDA positive in
2010. Sadly, profit-making still remains out of reach for at least for another couple of years.
Pricing Factor
One of the reasons contributing to the delay in profit generation is the pricing packages offered by WiMAX Operators.
Most WiMAX Operators have opted for the strategy of lowering their package pricing to combat intense competition from
their 3G/HSPA counterparts as shown in Figure 1. While this strategy has been effective in increasing market share, on
the other hand, it has a negative impact on earnings and profit margins.

Heavy Device Subsidies
Another important factor to consider as part of the WiMAX business model is the total cost of ownership (TCO) which typically
involves capital expenditures (CAPEX) and operating expenditures (OPEX) of the operator. CAPEX usually constitutes a larger
percentage but OPEX will outweigh CAPEX overtime. Figure 2 gives a brief breakdown of categories within the cost of
ownership, these categories comprise of CAPEX and OPEX costs.

Figure 2: Cost categories of WiMAX
It is important to note that device subsidy is one of the cost categories mentioned above and can impact the operators
profitability. For example, according to Yankee Group, due to AT&Ts subsidy model, it takes 17 months into the two-year
iPhone service contract for the operator to recover its expenses. Without subsidy, AT&T would break-even within 8
months!

Cost Effective Modem
Modems can play a vital role in churning out a profitable business for WiMAX Operators. Choosing a cost effective modem that
fits the user and marketmarkets and uses need would help WiMAX Operators determine an attractive package pricing and
modem subsidy policy to obtain a more favourable break-even period.

Device subsidy takes up 8% of an operators TCO as
shown in Figure 3. While subsidies have benefited
operators during the growth phase, it delays profitability.
On the other hand, channeling the full device cost to users
would dramatically increase package pricing and risks
turning customers away.
How can WiMAX Operators strike a balance between
device subsidy and profitability? The answer lies in
cost-effective devices.

Understanding User and Market Needs
User Needs When Less Is More
Most integrated WiMAX modems have multiple data (RJ45) and voice (RJ11) ports, even as many as 4 ports. However,
at large, basic broadband users (typically residential users) only require one data port and one voice port as illustrated in
Figure 4 below. Instead, what varies is their usage pattern which is construed by the amount of data consumed andspeed required. Hence, while excess ports contribute to the additional cost of the modem, they are not utilized.
Figure 4: One data and VoIP port is sufficient to support users typical broadband usage pattern
Market Needs Emerging Markets
WiMAX is deployed in both developed and emerging markets; however, 78% of the deployments are concentrated in the
latter market. Emerging markets present a more appealing opportunity for WiMAX as wireline infrastructure is scarcely
available and expensive to deploy, which ultimately leads to high broadband fees. Other factors driving WiMAX in
emerging markets include:
Low broadband penetration
Limited broadband availability
New entrants can get a large market share Low price elasticity among residential subscribers
Initial focus on fixed broadband
The above factors prove the growth potential of WiMAX. It is important to note that while these countries are rich with
natural and human resources, affordability is relatively low. With this in mind, WiMAX Operators have to offer affordable
packages without jeopardizing ARPU. In addition to requiring fixed (indoor) modems, emerging markets need
economical WiMAX modems.

Low Bandwidth Requirements & Internet Sharing
Meanwhile in developed markets, users often take for granted that computers are personal devices, even if the computer
is used for work purposes. However, in emerging markets, expectations around computer usage are drastically different.
In some communities, users share the Internet to execute low bandwidth applications. For the majority of people in
developing countries such as India and the Philippines, computer usage is primarily within shared, public environments
such as internet cafes or school labs. Walk down any street in New Delhi (India) or Manila (Philippines), it is a common
scene to see people of all ages editing their resumes, catching up on email or social networking.

Case Studies
Narrowing Digital Divide in Lao Cai, Vietnam
Lao Cai (Vietnam) is an economic center of rural agriculture where the economy depends on building robust
relationships with neighbouring trading partners. Though there is good cellular phone coverage across this
mountainous region, no such coverage exists for data services. Internet access is available through dial-up whichis often slow and unreliable. As part of Intels World Ahead program to bridge digital divide between developed and
developing nations, WiMAX was introduced to this province. Nearly 20 fixed-access WiMAX modems were
installed at the local post office, Internet cafs, government office, secondary schools, healthcare centers, hotels
and farm households to provide quality broadband services.

Empowering Medical Attention in Parintins, Brazil
Meanwhile in Parintins, Brazil, an isolated island city with 114,000 inhabitants, residents struggled to get medical
attention with only 12 general physicians and 20 specialists. Intel installed a WiMAX network for a primary
healthcare center and several other community places, including the Amazon University. This enabled Amazon
University to start a telemedicine program with the School of Sao Paolo University. The islands doctors benefittedfrom a faster and greater access to the latest medical data to help in preventing diseases.

Market Needs Developed Markets
In developed markets, WiMAX is often deployed to complement wireline broadband and address the underserved areas.
With its wireless advantage, high data capacity, cost-effective and quicker to deploy, WiMAX has emerged as a favourite
technology to reach rural areas.
Improving the Agriculture Industry, New Zealand
Contrary to common perception that rural areas do not have a pressing need for broadband, in developing countries,
rural areas is a burgeoning market that needs broadband attention. For example, in New Zealand, agriculture (a rural
based industry) is the main export industry. In fact, as of June 2009, agriculture represented 47% of the countrys total
exports, as shown in Figure 6.
Source: Wikipedia
Figure 7: New Zealands Agriculture Exports as of June 2009
With agriculture holding a pivotal role in its economy, New Zealands rugged and remote location has demonstrated to
be a major barrier to broadband access in rural areas. Farm owners need realible Internet access to efficiently
communicate with export supply chain vendors and coordinate export efforts.

Case Study
Waimate West Farm, New Zealand
In a study conducted by Intel in the Taranaki Region, Brent and Annette Perret who are the Farm Managers ofWaimate West Farm stated that for many years, they have been connecting to the Internet via dial-up twice a
week. Unfortunately, the connection was unrealiable and they were often left frustrated at the slow connection.
Furthermore, in using dial-up, Brent and Annette were not able to make telephone calls as the connection was
engaged for Internet. Like Brent and Annette, business communities in New Zealands rural areas were looking for
a solution to their rickety and snail-paced Internet connections.
The solution was WiMAX! Broadcast Communications, in partnership with Airspan Networks launched 28
WiMAX sites in November 2003. This initiative provided a dependable broadband connection to
50% of New Zealands household that did not have broadband access.

Basic Modems Deliver
From the case studies explained above, it is clear that WiMAX users, both in emerging and developed markets can be
effectively served through basic modems that meet their basic broadband needs. Target households often possess only
one computer which is shared by the entire family unit - as such, fixed indoor modems are often the best choice for this
audience.
Additionally, basic modems (with one data and VoIP port) are cost-effective as they only contain the necessary ports to
deliver the required broadband access but do not compromise on performance. This helps Operators to offer affordable
packages without over-straining CAPEX. For example, one of the packaging strategies adopted by Operators is to offer
free WiMAX modems upon sign up. While this strategy is attractive in increasing WiMAX adoption, operators are forced
to spend precious CAPEX in subsidizing the modems cost. By purchasing economical modems, WiMAX Operators can
subsidize the modem but at a reduced CAPEX.

Model #3 Financial Analysis based on Modem Subsidy
Figure 10: Breakeven and profitability timelines based on 100% and 50% modem subsidy models
These business models illustrate how earnings and profit can be significantly boosted through a proper business model,
which involves manipulating the projected subscriber numbers, ARPU rate or modem subsidy.
Realistically, a WiMAX Operator may not have full control over its subcriber acquisition efforts and market forces can
impact the projected number. On the other hand, affordability is a determining factor in increasing ARPU rates. Users are
very price sensitive a pricing package that is outside their affordability league can jeopardize the Operators subscriber
acquisition efforts and in worst cases, result in high customer churn.
Hence, the more feasible option is the modem subsidy model which is also an attractive marketing strategy. By
promoting a package with price cuts, users would be instantly attracted to the discount and sign up. However, in order
to not hurt capital reserves of the Operator, it is important that the Operator acquires economically priced modems.
Does an economic modem fall short in terms of performance and usability? Not necessarily.
Subsidy Rate
CAPEX + 100% Modem Subsidy
CAPEX + 50% Modem Subsidy
Conclusion:
Modem subsidy has great impact on the overal financial results over the long run. If the Operator subsidizes 50% of
the modem, the overall OPEX can be reduced by more than 15% every year and profitability can be brought forward
by 1.5 years.
