Academic Plan

Principles• To enhance the learning experience• To enhance research, discovery and creativity• To promote multi-disciplinary inquiry• To give back to the community

Inquiry and Blended Learning

Inquiry Based Learning

Seeking of truth, information and knowledge through the process of questioning

Blended Learning

Thoughtful and logical integration of the inherent strengths of face-to-face and online learning

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 format”

Wireless Project Sponsor

• In December, 2004, President Harvey Weingarten decided that wireless access for students was a top priority

• Funding was made available

• Outsourcing was considered

Why Not Outsource?

• Outsourcer wanted to segregate wireless network from campus networks

• Separate management platform

• Loss of control of applications on wireless

• Had to rip out existing wireless hotspots

• 5 year contract

• Cost

Existing Wireless Access

• AirUC– 150 Heinz 57 access points

• RezNet– 144 Nortel 1st Gen access points– 1600 pillows– We also provide dialtone and voicemail– Ethernet access for 800 pillows

AirUC

Reznet Upgrades

• Upgraded and reconfigured many access points (APs)

• Installed “Fortinet” to mitigate malware traffic – no need for scan and patch parties

• Reznet for Residence students only

• Considered replacing 2250 controllers with Aruba – will do that in Phase II

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

Phase I

Phase I by September 2005Didn’t get go ahead until FebruaryFast track - 5 parallel activities

• RF Assessments• Equipment Selection• Installation• Management Tools• Post Production

RF Assessments

• Led by David Yang

• Used Ekahau

• In house staff and contractors

• Now have an experienced, well-trained resource

Wireless Coverage

Equipment Selection

• Invited 3 Vendors to provide overview– Cisco– Nortel– HP

• Cisco purchased Airspace!

• Decided to open up selection– Proxim, Symbol, Trapeze, Aruba

Equipment Selection

• Sent team to Silicon Valley to visit multiple vendors

• Decided on thin AP technology

• Integration with wired networks

• Seamless roaming for voice, multimedia

Why Did We Choose Aruba?

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

• 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 Protocol)• Remote packet capture from any AP

Installation

• With RF heat maps, can proceed with installation

• Required cable and conduit

• Built backend wired network with HP POE switches

• Lots of campus fiber

• Left cables dangling in ceiling!

Management Tools

• Integrate with wired networks

• Network Access Control

• Malware remediation and control

Post Production

Elluminate

More Strategic than Wired(1)

• Access– Usage growing rapidly– Many more devices – PDA, Blackberries, UMA

phones– 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
