Case Study: ETH Zurich achieves secure campus WiFi and real-time network control with Zyxel

Zyxel Brings Wireless Innovation to Tomorrow’s Innovators

ETH Zurich, the Swiss Federal Institute of Technology’s student housing project at its Hönggerberg campus, needed stable and secure wireless connectivity across a large dorm complex with many walls, high user density, and strict requirements for security, switching, and bandwidth management. To address these challenges, Zyxel provided a wireless networking solution built around WAC6503D-S access points, XGS3700-48HP switches, a USG1900 firewall, and NXC5500 wireless LAN controllers.

Zyxel implemented a centralized WLAN architecture with automated provisioning, high-density WiFi optimization, and strong security controls such as intra-BSS traffic blocking, IP Source Guard, DHCP snooping, and ARP inspection. The result was reliable wireless coverage for 500 residents, real-time monitoring and traffic management, and early detection of bottlenecks and failures before they could disrupt service.
