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

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
• Lesson learned from previous hotspots –
communicate!
• Strategies
– Banners
– Website
– Newsletter articles
– Work with External Affairs Dept
