U of C Mission The University of Calgary is a place of education and scholarly inquiry. Its mission is to seek truth and disseminate knowledge. Our aim is to pursue the mission with integrity for the benefit of the people of Alberta, Canada, and the world.
11
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
12
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
13
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”
14
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
15
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
16
Existing Wireless Access AirUC –150 Heinz 57 access points RezNet –144 Nortel 1 st Gen access points –1600 pillows –We also provide dialtone and voicemail –Ethernet access for 800 pillows

18
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
19
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
20
Phase I Phase I by September 2005 Didn’t get go ahead until February Fast track - 5 parallel activities RF Assessments Equipment Selection Installation Management Tools Post Production
21
RF Assessments Led by David Yang Used Ekahau In house staff and contractors Now have an experienced, well-trained resource
22
Wireless Coverage
23
Equipment Selection Invited 3 Vendors to provide overview –Cisco –Nortel –HP Cisco purchased Airspace! Decided to open up selection –Proxim, Symbol, Trapeze, Aruba
24
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
25
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
26
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
27
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!
38
Management Tools Integrate with wired networks Network Access Control Malware remediation and control
39
Post Production Lesson learned from previous hotspots – communicate! Strategies –Banners –Website –Newsletter articles –Work with External Affairs Dept
40
Applications Student access to Portal, BlackBoard, webdisk, email VoWIP Voice over Wireless IP GSM/WiFi Phones (UMA) Private VLANs Parking Security Inventory Bookstore Museum RFID
41
Blackboard Course Management System Almost all U of C courses are on Blackboard Integrates with Elluminate for Synchronous Audio and Video Presentations

Elluminate
48
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
49
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
50
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
51
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
