  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 http://www.ucalgary.ca/it/computing/netserv/wireless/images/airmap/

  7. Why Did We Choose Aruba? • Wireless Switch Technology • http://www.arubanetworks.com/pdf/WLAN-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

  8. 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

  9. 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

  10. 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

  11. 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

  12. 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

  13. Blackboard Student Survey Results Question 2

  14. Blackboard Student Survey Results Question 11 • Notes & Course Materials • Review notes after class • Sample exams & assignments • Announcements • Discussion boards • Input from both students & prof • Group projects • File exchange & email • Grades • Assignment submission

  17. 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

  18. 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

  19. 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

  20. 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

  21. Questions? Contacts: Architecture & Security • Dean Berschl – dberschl@ucalgary.ca Deployment & Operation • David Yang – yang@ucalgary.ca • He’s here at AirHeads Installation • Terry Bellward – bellward@ucalgary.ca Website: http://www.ucalgary.ca/it/wireless
