Cisco Catalyst 9800 Wi-Fi 5 10GbE Wireless Controller

The Cisco C9800-40-K9 is a wireless controller in the Catalyst 9800 family that gives network administrators a single, reliable point of control for campus-wide Wi-Fi 5 deployments. With support for 10 Gigabit Ethernet uplinks, it keeps pace with bandwidth-intensive applications and high-density user environments.

Designed for organizations that expect rapid growth in connected devices, the controller can manage up to 2000 access points and 4096 clients without sacrificing performance. This scale makes it a practical choice for corporate headquarters, university campuses, or large hospitality venues where seamless roaming and consistent policy enforcement are essential.

Security is built in from the ground up. Data traveling over the air or the wired backbone is protected through AES, CCM, CCMP, and WPA2 encryption. RADIUS integration streamlines authentication, while VLAN support allows straightforward segmentation of traffic for guests, employees, or IoT devices.

Day-to-day management is simplified through remote management protocols that let IT staff push configuration changes and firmware updates from a central dashboard. The 1U rack-mount chassis slots easily into a standard equipment rack, and compliance with FCC and IEEE standards helps ensure dependable operation in regulated environments.

Typical deployments include multi-building office complexes, healthcare facilities, and retail chains that need a scalable solution capable of growing alongside expanding wireless demand. By bringing the Catalyst 9800 controller into the network core, teams gain the flexibility to roll out new SSIDs quickly, enforce consistent security policies, and adapt the WLAN as new sites come online.
