Campus Technology Vision
Connected Campus
“Enabling the learning, research, and
administrative, and community goals of the U of
C, through the effective and efficient use of
technology; allowing people to access
information they need, at the required time, in
the desired location, and in the appropriate
Wireless Project Sponsor
• In December, 2004, President Harvey
Weingarten decided that wireless access
for students was a top priority
• Funding was made available for two years
Wireless Initiative
• Phase I
August 31, 2005
Targeting “student spaces”
Ground floor of all buildings with student spaces
Add 400 access points
• Phase II
– August 31, 2006
– Ubiquitous campus coverage
– Add 800 access points
Wireless Coverage
Why Did We Choose Aruba?
1. Wireless Switch Technology
– “dumb” access points (APs)
– All traffic tunneled back to central controllers
– Can place APs on dedicated wired networks
or on any network on campus, on the
Supernet, or anywhere else on the Internet
2. Security
ICSA Certification
Per User Firewall
VPN Termination
Basic IDS/IPS (Strong offering available)
Virus Control offloading (via Fortinet)
Remediation (via Sygate OEM)
Full Featured Captive Portal
Additional Critical Features
3. Additional Critical Features
– Wireless delivery across internet/NAT boundaries
(AirUC at home or anywhere on the internet)
– Can route wired connections through Controller to
offer functionality to wired ports (captive portal,
firewall, guest access, virus control, remediation, etc.)
– Infinite expandability of number of AP’s
– Make use of existing AP’s (roaming, captive portal,
some management) – Others must replace all legacy
AirUC AP’s
– Integrates with Microsoft NAP (Network Access
– Remote packet capture from any AP
Student access to Portal, BlackBoard, webdisk, email
VoWIP Voice over Wireless IP
GSM/WiFi Phones (UMA – Unlicensed Mobile Access)
Private VLANs
Cellular/WiFi Dual-mode phones
• Regular Cell plan with free VoIP over WiFi
• Strategic direction for campus telecom
– Replace desksets and cell phone with single
• Requires Seamless Roaming
Interoperating with Your
Access Points
You know who you are out there!
• Channels – 1, 6, 11
• Can provide a VLAN with your SSID and
choice of security (WEP, WPA)
• Remote VLAN access
– Can provide AirUC or your SSID at a remote
site anywhere on the Internet

Question 15
More Strategic than Wired(1)
• Access
– Usage growing rapidly
– Many more devices – PDA, Blackberries, UMA
– Future faster wireless technologies
• WiMax, 802.1n, etc.
– Many more uses – IM, Videoconference, etc
– Re-assess computer lab strategy
• Currently around 2500 computers across campus
• AirUC usage high-water mark so far @ 1200
– Remote AirUC over Internet
More Strategic than Wired(2)
• Cabling
– 15,000 cable runs
– 80% still Cat 3
– Revising cabling standard
• Network
– Standards revising
– More POE switches
– Less drops per location
– Gig home runs only as required
More Strategic than Wired(3)
• Telecom
– Migration of TDM to VoIP
– Unlicensed Mobile Access (UMA)
• Cell voice and data services over WiFi
• 1000 university-paid cell plans
• Combine deskset & cell handset
Where are we now?
Number of access points (APs): 700
Number of buildings with coverage: 35
Total coverage:
290,000 sq m
Total University space: 509,000 sq m
