Over the past 10 years, we have witnessed an incredible evolution in wireless networking. Centrally managed intelligence driving increasingly distributed lightweight access points has been pioneered for the successful wireless experience, no matter where our users are located. Now it maintained for key principles that emerges as mandatory and timeless during this period providing flexibility, while the architecture was always adapting to the future that we can never quite predict high throughput, especially in the face of increasingly complex security policy like a ACLs, encryption and etc.
Moreover, availability and redundancy are mandatory even when upgrading hundreds of applications or LAN links. Also, enabling mobility for seamless roaming even at layer 3. The robust controller architecture allows much larger subnets of wireless users in the core meaning no more wireless V-LAN on overload and multiple attempts to gain control and no trunking.
Cisco’s wireless controllers are essential component of intent-based networking. This means that with an intent-based network from Cisco, your network grows more intuitive every day, because it is informed by context and powered by design.
A WLAN is a wireless architecture that intends to meet changing network demands. A WLAN controller handles wireless network access points which allow wireless devices to connect to the network.
What a wireless access point does for your network is alike to what an amplifier does for your home stereo. It takes the bandwidth coming from a router and stretches it so that many devices can go on the network from farther distances away.
Cisco WLC License:
Choosing the right type of deployment and making sure that your controller matches the size of your organization is important. Some controllers, for instance, the Catalyst 9800-80 Wireless Controller, are built to handle the traffic of a large organization. That same controller would be overkill for a small business. Similarly, a controller like the Cisco 3504 Wireless Controller is intended for smaller business offices and manages a few access points–it would never be able to handle the day-to-day activity of a large enterprise.
Cisco WLC products include physical controllers such as, Cisco Catalyst 9800, Cisco public and private cloud controllers, Cisco embedded wireless controllers and Cisco controller-les Mobility Express.
Most Cisco’s WLC products supports smart licensing for registering all product instances on the Cisco software management website.
