Wireless controllers Cisco WLAN Controllers reduce overall operating costs by simplifying network deployment, operation and management. Applying the same security policies and principles «networks without borders» from the core of the wired network to the wireless edge segments allows wireless network controllers Cisco Provide transparency, scalability and reliability required to build protected wireless networks of the enterprise — from branches and small businesses to large campuses.

They support the flexibility in setting up policies, control and wireless network protection parameters at any time thanks to the means of centralized resource allocation and management.. WLAN controllers Cisco have a faster response to business requirements through centralized management of wireless networks. Standardized process for configuring access points for software versioning and wireless intrusion prevention (wIPS) also present in controllers Cisco.

WLAN controllers Cisco support E2E service quality architecture (QoS) for voice and video transmission in wired and wireless networks and a single centralized management of security policies in wired and wireless networks. Also, the ability to use integrated wireless functionality in switches and routers provides cost-effective support for converged networks that include wireless segments.. The use of integrated platforms reduces hardware cost, simplifies remote management, and provides other flexible configuration options to reduce overall operating costs and total cost of ownership.

Wireless controllers Cisco WLAN Controllers represented by a wide range of models designed both for small businesses with a small number of users and access points Cisco, and for large branches with more than 10-20 thousand users, and a large number of access points Cisco. Wide selection licenses and updates for controllers Cisco allows you to expand the functionality and performance of wireless systems.
