  1. Mobility and Personal Computing Michael Barker, Ph.D. Assistant Vice Chancellor and Chief Technology Officer University of North Carolina at Chapel Hill

  2. The Environment • Mixture of communities • Residential students • Off-campus students • Privileged access workers, onsite and remote • Non-privileged access workers, onsite and remote • Guests • Mixture of contexts • “Academic Use” – e.g., classrooms, laboratories • “Administrative Use” – e.g., registration, payroll, fee payment • “Guest Use” – e.g., parents, donors, vendors • Mixture of “businesses”

  3. Key trends, undergraduates • 84% of undergraduates own a laptop; only 46% own desktops • Average 21.2 hours per week on internet • Handhelds • 63% own an internet capable handheld (51% in 2009) • 67% of those use it to access the internet at least once a week (29% in 2009, 43% in 2010) • 77% who own an internet capable handheld, use it to access social networking sites • Cloud • 36% have used web-based productivity application • 33% use wikis SOURCE: ECAR Study of Undergraduate Students and Information Technology 2010 (October 2010)

  4. Student usage trends • Daily use of text messaging • Increasing • 53% (2008); 66% (2009); 73% (2010) • Daily use of instant messaging (e.g., Jabber, AOL, Yahoo, MSN) • Decreasing • 48% (2007); 33% (2008); 28% (2009); 24% (2010) • Daily use of social networking sites • Increasing • 49% (2007); 57% (2008); 61% (2009); 59% (2010) SOURCE: ECAR Study of Undergraduate Students and Information Technology 2010 (October 2010)

  5. Some wireless numbers • Wireless Access Points • Approx 2000 at present • approx 5000 needed for pervasive coverage (excluding residence halls) • Devices: 50000 distinct devices • Concurrency • Peak last academic year: 10,021 distinct users • Peak so far this academic year: 13,409 distinct users • Bandwidth • Peak aggregate outgoing so far: 129 Mbps • Peak aggregate incoming so far: 536 Mbps

  6. Challenges • Security • E.g., laptop with ~16,000 viral signatures • Leakage of sensitive data • Policy protections / guidance • Exposing same services in various delivery modalities • Directory search • Add/drop • Course management system • Etc… • E.g., one person with 4 mobile devices (or 5) • Pervasive cellular versus pervasive wireless, versus both • Next generation voice services

  7. Strategies • Distributed Antennae System (and “Neutral Hosting”) • “personal” wireless will continue to grow in cellular networks • “business / academic / administrative” wireless will continue to grow in 802.11 networks • Bring (some of) your tools: faculty / staff cell phone stipend… • Design/architect for remote users • Remote capability for privileged access users the greatest challenge • Exposing services across network borders, to multiple platforms next greatest challenge • No other choice but to support standards and protocols, not specific devices nor specific mobile operating sys

  8. Cell phone stipend • Forcing conceptual review/analysis • On-call • Mobile worker • Remote wipe/erase • Modem cards • Tablets, netbooks, etc. • Porting numbers • Personal • Business • Erosion of traditional landlines, or not…

  9. Things to consider • What is king? • Contents? • Applications? • Media? • Public Privacy • Is there a mobile watercooler? • Of special concern for public entities • Public records, and “fixing” to a “medium” • Context commingling • Location no longer determines context • Does content drive context? • Does source / target drive context?

  10. And more things to consider • Communications across modalities • email • SMS text • Browser • Thick-client, mobile-style… • Technology-transformation and social-movement • email: 40 years (1970s) • SMS: 15-20 years (1990s) • http: 15-20 years (1990s)

  11. To infinity and beyond • Mobile-2-mobile • Pacemaker data • Medical alerts • Where is your car? • Data/persona portability • DRM for business-owned content
