1 University of Calgary AirUC Comtech Report December 13, 2005

2 AirUC Wireless: More Strategic Than Wired Tom Seto –Associate Director, Infrastructure –Dept of Information Technologies –University of Calgary –Responsible for Network Services, Telecommunications, and the Data Centre

3 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”

4 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

5 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

6 Wireless Coverage wireless/images/airmap/





11 Why Did We Choose Aruba? 1.Wireless Switch Technology – switching.pdf switching.pdf –“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

12 Security 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

13 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 Protocol) –Remote packet capture from any AP

14 Applications Student access to Portal, BlackBoard, webdisk, email VoWIP Voice over Wireless IP GSM/WiFi Phones (UMA – Unlicensed Mobile Access) Private VLANs Parking Security Inventory Bookstore Museum RFID

15 UMA 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 device Requires Seamless Roaming

16 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

23 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

24 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

25 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

26 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

27 Questions? Contacts: Architecture & Security –Dean Berschl – Deployment & Operation –David Yang – He’s here at AirHeads Installation –Terry Bellward – Website:
