Despite All Evolutions Voice Remains the Killer Application
201x, Where Are We Headed? A world where any type of digital content, information, and service can be affordably accessed and shared without regard to time, location, or device ANYTIME ANYWHERE
Personal Broadband is the Enabler Mobility Personal Broadband Bandwidth A new generation of personal broadband services is emerging that will enable subscribers to take their broadband connection with them anytime, anywhere and extend their mobile services to broadband speeds Personal broadband is always-on, high-speed and all-ip, providing direct access to the Mobile Internet and creating an open market for many service and application providers Personal Broadband is naturally wireless
The Wireless Scenario
Mobile WiMAX (802.16e) Mobile WiMAX is well suited to support Personal Broadband

The Importance of VoIP (1) Growth of VoIP in recent years Initially on wireline -> First driver of a Voice/Data convergence strategy Then on wireless -> First step towards a converged all-ip strategy Even in the Personal Broadband scenario, voice is and will remain a key driver in operators business. VoIP is rated as the single most important driving app in 2007-9 by almost 40% of operators planning to deploy WiMAX in that timeframe. By 2009 we will see at least 65% of operator aiming to offer sophisticated VoIP. Source: RETHINK, VoIP over WiMAX: Market drivers and vendor opportunities, May 2007
