  1. Importance of Mobile Broadband Smart “phone” is a misnomer These are actually handheld computers with voice as an application Consumers value having constant access to the vast pool of information enabled by the Internet wherever they are. This trumps fixed options. Mobile networks need to converge onto the Internet Using traditional telephone architecture, backhaul requirements for data are increasing by an order of magnitude Using 4G (System Architecture Evolution -- “SAE”) Phase II architecture, mobile broadband nodes connect as peers via the Internet and provide full mobility without backhauling to a converged core Business model for rural communities is radically changed with 4G Phase II Pulls the Internet cloud to rural communities in America Operating costs reduced by over 65%; performance improved by reducing latency Provides sustainable wireless broadband offering for rural telcos Spectrum need is critical for rural communities Fixed line business eroding, threatening the viability of rural telcos – the basic telecommunications fabric in rural areas Access to spectrum is major roadblock for rural wireless broadband; spectrum often held by larger carriers who have not built-out
