3. Aaaaaaaaaaaa: Market issues – Incumbent’s concern • What technologies will have the greatest impact on the industry, and how? • How fast VoIP will overtake the traditional fixed voice? 2. How will demand for mobility and multimedia drive fundamental changes in the industry? 3. Which technology providers will win or lose, and what’s the impact? Subject: Broadband Wireless Technologies for the Delivery of Converged Services

4. Bbbbbbbbbbb: Wireless data is 20% of total mobile services revenue while wired data is 24%, in 2007 By year end 2008, majority of telecom revenues will be based on wireless. Wireless service revenue surpasses fixed. Service Revenues Source: Gartner Dataquest, October 2005 Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

5. Personal details: Operator’s concern – Strategies to Follow • Threat • Only Wholesale Provider of Broadband services • Strategies • Go wholesale • Go mobile again (UMA) • Invest in fixed broadband • IPTV services Fixed Operators • Threat • Mobile VoIP and fixed VoIP • Single flat fee for Mobile data • Strategies • Fixed-Mobile Substitution • Bandwidth pricing • Content via mobile portals Mobile Operators COSMOTE • Threat • Combined fixed and mobile threats plus high discounts for commercial bundles • Strategies • Fixed-Mobile Convergence • Content ownership • Unicast and broadcast • Home Gateways Fixed & Mobile Operators Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

6. Personal details: Incumbent’s position Situation • We are Increasingly Wireless • We are Increasingly Faster • We are Increasingly Cheaper • Price erosion is significant, and has quickly spread to next generation services such as broadband and 3G voice. • Convergence comes in many flavours - Fixed/Mobile, Telecom/IT, Telecom/Media, Terminals, Services, Applictions.. • Competition Increases • Answer? • Making strategic decisions (invest on new technologies – integrate daughter companies to mother one – provide motives to old personnel for the sake of new personnel) • Fixed and Mobile speeds are increasing at accelerating speeds Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

7. Cccccccccccc: IP net WiFi Handover Mobile Operator GSM or UMTS What isUMA - GAN? UMAone terminal (mobile – wireless - fixed)for all services • How is achieved? • User moves in and out of WLAN proximity without loss of call • Seamless call Handover once you move from WiFi toGSM and vice versa • UMA extends the GSM coverage in indoor environments (Houses, hot spots andSOHOs) through the use ofWiFi access points Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

11. Personal details: UMA Roadmap & Evolution Home • Fixed operators integrate wireless and fixed to prevent erosion • Selling points: one device, one number, one bill, one messaging platform • But primary value is reduced tariffs for fixed vs. mobile (via VoIP or PSTN) and convenience of single handset • If mobile voice pricing continues to fall (permitted by 3G spectral efficiency), what's the incentive to still used fixed for voice? • Result: Consumers will more rapidly migrate to mobile only than to converged fixed/mobile Fixed Operator GSM/VoIP DSL or PSTN W-LAN MVNO or Reseller Hand-over Mobile Operator GSM or UMTS net Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

12. Personal details: Femtocells Femtocellsare small cellular base stations similar to (GSM/UMTS)stations which have been designed for use in indoor environments. Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net

13. Personal details: Femtocells key points • Access point GSM/3Gin indoor environment coverage ≈ 50m • Allow the same terminal to be used indoors and outdoors • Low power consumption (10μW-25mW) • Seamlesshandover from macro cells tofemtocell Subject: Broadband Wireless Technologies for the Delivery of Converged Services dariusz.rozanski@szczesliwice.net
