Cisco Catalyst 9800-L Overview

Wireless estates now need consistent policy, reliable roaming and predictable performance while supporting hybrid work, guest access and day-to-day change without adding management overhead.

Centralised Control for Smaller Wireless Domains

The Cisco Catalyst 9800-L is a fixed wireless controller for small and midsize enterprise WLANs. It suits sites that want controller-based control for access points, policy and software updates across offices, campuses or distributed locations.

Built to Support Operational Consistency

With support for up to 250 access points and 5,000 clients, the platform gives network teams a single point of control for a defined wireless estate. High Availability support adds resilience where service continuity matters, and 5 Gbps controller throughput helps the environment stay responsive under normal operational load.

More Predictable Day-to-Day WLAN Operations

This makes roaming, policy enforcement and troubleshooting more consistent across user groups and spaces. It also helps reduce time spent managing APs as separate tasks, while keeping the wireless design aligned to the site’s coverage and management needs.

Our team can help you plan and deploy the Cisco Catalyst 9800-L for your wireless environment, so control, resiliency and operational fit are set for the way the site runs.
