In addition to managing access points, a WLAN controller is integral when it comes to the type of network deployment you choose. There are two deployments that use physical controllers:
* Centralized deployment. The most common type of wireless network system, traditionally deployed in campuses where buildings and networks are in close proximity. This deployment consolidates the wireless network, allowing for easier upgrades and enabling advanced wireless functionality. Controllers are based on-premises and are installed in a centralized location.
* Distributed deployment. This solution is tailored for small campuses or branch offices. It allows customers consistency in their wireless and wired connections. This deployment converges wired and wireless on one network device--an access switch--and performs the dual role of both switch and wireless controller.
