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 Tech A 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.
