Mobile Broadband: Huge Demand, Huge Challenges
Mobile voice revenues saturating
Mobile broadband driving growthTraffic up 130% per yearDoubling every 9 months!
BUT new base stations & spectrum adding only 20% capacity / year
Video is the true network killer appWill bring mobile networks to its knees!Data streams are no longer bursty
Ex: Peer-to-peer (P2P) & streaming
