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
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
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
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
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
