About This Architecture

Enterprise wireless network with redundant three-tier architecture spanning core, distribution, and access layers across two zones. Dual firewalls protect the DMZ and LAN, with primary and secondary core switches (10.10.0.0/24) providing backbone resilience. Wireless LAN controllers in VLAN 20 manage access points across Zone A (VLAN 30) and Zone B (VLAN 40), each with redundant access switches and four APs serving laptops, mobile devices, and IoT endpoints. This design eliminates single points of failure at every tier, ensuring continuous connectivity during component outages. Fork and customize this diagram on Diagrams.so to match your campus layout, IP addressing, or add additional zones. The redundant WLC and switch architecture supports seamless roaming and failover for mission-critical wireless deployments.

How do you design a redundant enterprise wireless network with no single points of failure?

This diagram shows a three-tier architecture with dual firewalls protecting the core, redundant core switches in VLAN 10, primary and secondary WLCs in VLAN 20, and dual access switches in Zones A and B (VLANs 30 and 40) each serving four access points. Every critical component has a backup, enabling seamless failover and continuous wireless connectivity.
