Goals For Today: • • Defining “mobile infrastructure” Quick mobile technology overview & history Mobile infrastructure in the campus context: now & future Crossing the infrastructure-application boundary 1
Infrastructure defined: The term IT Infrastructure is defined in ITIL v 3 as combined set of hardware, software, networks, facilities, etc. (including all of the Information Technology), in order to develop, test, deliver, monitor, control or support IT services. Associated people, Processes and documentation are not part of IT Infrastructure. 2

UC Berkeley Mobile Network Today (wifi) Campus Wifi Networks: Airbears for all campus & Res. Comp in the dorms (802. 11 b/g) • • Network funding model, getting incentives right Airbears coverage: Red=partial building coverage Green=full 5

Mobile Devices at UC Berkeley What we have at UC Berkeley today: Devices (from UC Berkeley / California Digital Library 2010 Community Mobile Survey) 67% have desktop (declining) 95% have laptop/notebook 12. 4% have tablet (10% plan to buy) 11% have e. Reader (e. g. Kindle) 61% have non-internet mobile phone 54% have smartphone (16% plan to buy) 8

Trends vs Hype for Mobile Use Economic Drivers Google & Apple: App stores=control of revenue Apple: a hardware company first: ipod->iphone->ipad->? ? Carriers: $$ data plans, infrastructure costs 11
Trends vs Hype in Mobile Devices 12
“Enterprise” Mobile Considerations 13
New devices, new consumption patterns A smartphone generates 24 times the mobile data traffic of a conventional wireless phone, and the explosively popular i. Pad and similar tablet devices can generate traffic comparable to or even greater than a smartphone. AT&T’s mobile data volumes surged by a staggering 8, 000% from 2007 to 2010, and as a result, AT&T faces network capacity constraints more severe than those of any other wireless provider. -from AT&T Filing prior to T-Mobile acquisition 14
Trajectory of our Plans at UC Berkeley The Past and Future of Berkeley-owned mobile infrastructure 1) 2) 3) 4) Access: availability and capacity Landlines vs. Mobile Security Innovation: policy; approaches & economic realities 15
Applications & Mobile Infrastructure Good advice for mobile: “Don’t overthink it. ” Mobile infrastructure = IT infrastructure Mobile security = IT security Mobile applications = IT applications • So What’s Important? • • Meeting user needs by accommodating form factor changes Realize added value by addressing opportunities of the mobile context Broad mandate for mobile use-cases (“mobile first”) Institutions addressing implications of device consumerization Innovation vs Standardization in a rapidly evolving landscape Mobile frameworks, HTML 5 vs. Native Compression and mobile performance 16
