3G Data Services: Network Resources vs. Revenue

9.
• Mobile Internet/Intranetaccess will require10-200Xnetwork capacity of voice per subscriber
-Desktop-equivalent 3Gaccess for laptops andPDAs is unlikelyto produce revenueproportional to the
requirednetwork investment
• Wireless data roamingcombines 3Gtechnologies for wide-area, mobile coverage with WLANaccess for
localized high-data-ratecoverage
-One-bill roaming is first essential step to full 3G/WLANservice integration
-Full handoff with session continuityis not required to meet currentcustomer expectations
- Availability of converged devices andservices such as VoIP could change this
How Public WLANs Compliment 3G Services

10.
• WLAN business models arestill in early development stages
• Residential and enterprise WLAN adoption drives demand for public WLAN access
• A large majority of new laptop computers produced today are equipped with WLAN
• Multiple business and pricingmodels arebeing tested for sustainability
- Manyservice providersareelecting nottobuild out their own WLAN networks orlimiting deployment tostrategic
locations
- Flat rate, per session, per minute pricing
Public WLAN Business Models

11.
Case Study: SBC
• Currentlyoperates over 4500hotspots
- UPS Stores, Barnes andNoble Bookstores
• Currentlyprovides access to their wireline, DSL, and dial-up internetcustomers
• Expected to provide access to their cellular subscribers
• Offers their hotspots to otherproviders via roaming agreements
Public WLAN Business Models (continued)

12.
Case Study: Sprint
• Currentlyoperates 20 hotspots
- Mostly airports
• Currentlyprovides WLANaccess to their cellularand enterprise subscribers
• Plans to provide subscribers access to morethan 25,000domestic and international hotspots by
yearend 2005via roamingagreements
• Focusing their efforts on supporting securemobile workforce access across 1xEV-DO, WLAN
(enterprise, homeand public access), and dial-up
Public WLAN Business Models (continued)

13.
Case Study: unnamedsmall wireless operator
• Currentlyoperates no hotspots
• Desires to provide their existing wireless subscribers with WLANaccess
• Planningto launchservice consisting of access to 6000+hotspots exclusively through roaming
agreements
• Retail pricing will bebased on markingup the negotiated wholesale roamingrates
• This creative approach has verylittle financial risk

Unique role of WiMAX for Wireless Operators

15.
• Exitingwireless operatorshaveanadvantagein thattheyusuallyhavealreadysecuredbase

-Wireless operators can either provide WiMAXservices directly or provide access for other WiMAX
providers
• WiMaxis anexcellent technologyforsupportingWLANbackhaul
