Moivaion Mobile broadband (MBB) has jus recenly enered he scene Evoluion in number of subscripions and raffic is very uncerain The radio access and backhaul elemens are he mos cosly pars of mobile (broadband) neworks Coss of hardware and sofware upgrades, and backhaul are heavily driven by BH raffic (which is uncerain) Undersanding he impac of uncerainies on he profiabiliy of Mobile Broadband is key How robus is he business case?
MBB profiabiliy is under pressure Will coss follow he raffic curve? Traffic (volume) Traffic Revenue Revenue Voice dominaed Daa dominaed Time
MBB profiabiliy is under pressure Cos efficiency Decreasing subscripion prices and increasing MBB volumes requires lower price per produced bi I is expeced ha he new echnologies will have reduced cos per bi Srong link o he increased capaciy driver Producion cos per bi Cos per Mbye 3G HSPA HSPA+ LTE
