Implementation: Wi-Fi controller

This section shows how Mikrotik helps building a Wi-Fi system for general Internet and office network purpose. Unlike "Wireless System" which target industrial wireless applications, this page will only focus on Mikrotik CAPsMAN, a Mikrotik only Wi-Fi controller system and proves how it helps building world most cost effective and fully functional and easy-centralized-manageable Wi-Fi system.


What is CAPsMAN

Mikrotik CAPsMAN (Controlled Access Point System Manager) allows centralization of wireless network management and if necessary, data processing. When using the CAPsMAN feature, the network will consist of a number of 'Controlled Access Points' (CAP) that provide wireless connectivity and a 'system Manager' (CAPsMAN) that manages the configuration of the APs, it also takes care of client authentication and optionally, data forwarding.

When a cAP is controlled by CAPsMAN it only requires the minimum configuration required to allow it to establish connection with CAPsMAN. Functions that were conventionally executed by an AP (like access control, client authentication) are now executed by CAPsMAN. The CAP device now only has to provide the wireless link layer encryption/decryption. Depending on configuration, data is either forwarded to CAPsMAN for centralized processing (default) or forwarded locally at the CAP itself.

Why Mikrotik

Nowadays wireless controller from famous bands like Cisco, Aruba and Ruckus are only affordable by enterprises or large organization because of budget limitation. But Mikrotik CAPsMAN can be formed by any Mikrotik router and APs which overall hardware cost is not a concern. And there is no AP license concern while up sizing AP numbers.
