Appeal for many cellular operators

WiMAX spectrum is new, underutilized,and less costly

Offers access to new wireless players…

& existing operators looking for time to market

Both have significant spectrum

»WiMAX = 790 MHz; LTE = 650 MHz

Both can be FDD or TDD, but...

»WiMAX development focused on TDD

»LTE development focused on FDD

Availability & regulations of spectrum is a primary driver in selecting WiMAX or LTE

Relative Number of Sites

3.5 GHz versus 2.5 GHz

» 3.5 GHz requires ~30% more sites than 2.5 GHz for given geography

» Increase in sites at 3.5 GHz results in ~ 13% increase in cost

» As a result, the 3.5 GHz network will also have 30% additional capacity

» 3.5 GHz system can defer capacity based build out longer than 2.5 GHz system

Broadband subscriber growth in Pakistan

So what brings WiMAX to Pakistan ?• Low broadband penetration.• Un-reliable fixed line infrastructure.• Poor support from incumbent fixed line provider.• Fixed Line infrastructure owned by one provider.

Dependent on that provider for last mile support and maintenance.

• Low Fixed Line Penetration and very small Cable/FTTH deployment creating a need for alternate means for fixed broadband access.

• Low CAPEX/OPEX, fast deployment• Governmental support by making new spectrum to help

bridge digital divide• Opportunity for new investors to enter the Telecom Market• Opportunity for incumbents to diversify

Success• Pakistan leading the drive towards 4G.• Wateen: World’s first nationwide deployment of

802.16e.• Four 802.16e operators

– Wateen, WiTribe, Mobilink, Augere• More then 100K WiMAX users• In less then two years, WiMAX powering 30% of the

total broadband connections in Pakistan.• Regional leader in WiMAX expertise• Motorola has setup its Regional WiMAX Support

Center in Lahore, which provides Technical support to Motorola customer in EMEA and ASIA-PAC

Challenges• Low ARPU market.• High Cost of CPE• Lack of Prepaid penetration. Contract based

packages to subsidies CPE cost.• Coverage based deployments impact availability• Internet backhaul not sized appropriately, limiting

performance gains of broadband access.• Interconnect charges throttling growth of Voice

over WiMAX service• Cost of Internet backhaul, still not relative to

local buying power• Lack of Blanket coverage.

Future• WiMAX will continue to drive the broadband growth.• Rate of growth dependent on availability of end

devices meeting domestic price points. ($50 for basic data device)

• Introduction of Prepaid model similar to existing Cellular service. No contract required.

• Customer can use same end device to get service from any WiMAX provider

• WiMAX support on Intel Processors will accelerate this growth

• Possible introduction of Mobility.• Expansion into rural markets.• Capacity and coverage expansion on existing networks
