Why Did We Choose Aruba?
1. Wireless Switch Technology
– http://www.arubanetworks.com/pdf/WLANswitching.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
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
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
