  1. A View From the Tip of the Wireless Iceberg Dr. Ronald R. Hutchins Associate Vice Provost for Research and Technology and Chief Technology Officer, Georgia Institute of Technology

  2. Networking/Wireless at Ga TechA Context… • Internet • Internet 2/SoX • NLR/SLR • LAWN • Local Area Wireless and Walkup Network • Applications Task Force - integration of Applications over Cellular, Wi-Fi, wired

  3. LAWN stats • Started in 1999 • Captive portal authentication w/static WEP • >850 Access Points (1000 by year end) • >80 buildings covered • >50% of students use regularly • Commercial network (FASTPASS)

  4. The Stuff… • LAWN • GPS Bus tracking via google maps • Bus hotspot via Wi-Fi and GPRS • UMTS rollout on campus • IMS apps platform • Research contract with Cingular • Connecting @ L2 with cell towers • Telecom project on campus - not VoIP today • Cellular PBX model ???

  5. Wireless Futures • Flattening of voice revenues, growth in cellular data and sales/services. • Cellular and VoIP combining to impact traditional land lines. • Reclaimed and Unlicensed frequencies. • WiMax on the horizon - a converged wireless?

  6. Beyond Wireless • Presence • location based services • seamless mobility • sessions • multi-homing • Convergence (services & hw) • Identity management • Security

  7. Why these things are challenging • human interaction • commercial constraints • Open -vs- closed • privacy/trust

  8. Presence • Chat + context • Who is asking the question • For what purpose • virtual presence in the absence of physical presence

  9. LBS • Augmenting my services with information about where I am, where I am headed, and where my friends and colleagues are.

  10. Mobility • Not just between cell-phone towers but between different technologies: cell, wi-fi, wired • Able to take advantage of the best service currently available. • The "affordances" ideas (Jeff Pierce GT-GVU) -- a screen, printer or keyboard that is close by and usable

  11. Converged Services • Services converging and crossing networks • voice as another data service • data - messaging, imaging becoming as important as voice

  12. Device Convergence • Voice/video/text communications, media player, camera, web • single purpose device (iPod) -vs- a multipurpose one (Treo) • Devices will pool resources - not all will require all forms of wireless… • Small form factor wireless devices are quickly becoming the dominant computing platform…and as a result, the device for students to program

  13. Identity Management • Who am I? • a phone number? • a IP address? • a email address? • a secret password? • a hidden code on a chip or magnetic stripe? • a fingerprint or DNA sequence? • All of these have problems - We need this for two reasons • How will others find me? • How will they trust that it's really me?

  14. The Black Ice • Security continues to be a major problem with wireless, what does security mean? • Impersonation, interception of voice/data streams, tracking of inappropriate behavior, denial of services, propagation of viruses, etc. • How do we continue to grow services in the face of these growing challenges? • Security is not just a “network” problem, it must become everyone’s problem, but more specifically the customer must be cognizant and take action to protect content, identity, and property.
