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

Femtocells Deliver “Cheap Pipes”

Femtocell = home base station

Works with standard 3G & LTE handsets / data cards

Traffic backhauled on users’ fixed broadband (DSL / Cable / FTTx)

Data Traffic offloaded from the macro cellular network
