the environment
The Environment
  • Mixture of communities

    • 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”

  • 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)

some wireless numbers
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
challenges
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
strategies
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
cell phone stipend
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…

  • What is king?
    • Contents?
    • Applications?

  • Context commingling
    • Location no longer determines context
    • Does content drive context?

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)
