11. Subject: Broadband Wireless Technologies for the Delivery of Converged Services 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 Personal details: dariusz.rozanski@szczesliwice.net Home DSL or PSTN Fixed Operator Mobile Operator Hand-over GSM/VoIP W-LAN GSM or UMTS net MVNO or Reseller UMA Roadmap & Evolution
