WLAN

What is WLAN?

Wi‑Fi networks are a type of WLAN but not all WLANs are Wi‑Fi. Other radio transmissions that connect local network nodes are also WLANs. However, Wi‑Fi is the type of WLAN that is most widely used.

Wireless controllers, sometimes referred to as gateways when operating in a cloud-managed environment, provide high-performance access, resiliency, and security across the WLAN, LAN, and SD-WAN.

Next generation WLAN controllers deliver:

• Performance at scale to support thousands of APs and devices with 24×7 reliability, zero touch provisioning, and live upgrades thereby reducing the need for on-site IT support.
• Security enforcement with granular role-based rules and dynamic segmentation.
• L2/L3 roaming across VLANS to allow seamless handoffs and improved user experience.
• N+1 or NxN redundancy for greater performance and scale.

HPE Aruba Networking offers a full portfolio of WLAN controllers and gateways to meet the needs of mid-sized branches and large campus environments. Recognized as a leader in WLAN, HPE Aruba Networking continues to innovate with the 9000 Series Gateways for branches and small campuses and the 9200 Series Gateways for larger environments.

• 9200 Series.
• 9000 Series.
• 7200 Series.
• 7000 Series.
• Mobility Controller Virtual Appliance.

If there are too many devices on a single LAN, it can create congestion and bottlenecks. To eliminate broadcast overhead and improve security and performance, the network can be divided into multiple virtual LANs or VLANs.
