Why is the market transitioning to WiFi?Increased demand and improved customer experience
• Over 80% of all mobile internet and video usage in the US takes place in a fixed location
• Many smartphone applications are nomadic, not mobile, allowing WiFi to provide the necessary access
• Almost half of all smartphone and tablet device traffic is already connected via WiFi
• US households are moving aggressively towards broadband untethering; by 2015 nearly a quarter of broadband households will purchase a mobile/cellular element
• The number of WiFi connected portable devices will double between 2010 and 2015
• Technology improvements are delivering a more cellular-like experience, which will accelerate WiFi use
• By 2014 US public WiFi hotspot usage will have grown 200%
