What do fit and fat modes mean?

Fit mode is a WLAN networking mode. Compared with the Fat mode solution, a wireless switch or wireless controller is added as a central centralized control and management device; while the Fat mode is a traditional WLAN networking solution, the wireless AP itself It undertakes complex functions such as authentication termination, roaming switching, and dynamic key generation. Relatively speaking, the AP has heavier functions.

What do fit and fat modes mean?

1. Fat mode is a traditional WLAN networking solution. The wireless AP itself is responsible for authentication termination, roaming switching, and dynamic encryption. It has complex functions such as key generation. Relatively speaking, the function of AP is heavier, so it is called Fat AP.

2. Fit mode is an emerging WLAN networking mode. Compared with the Fat mode solution, a wireless switch or wireless controller is added as a central centralized control and management device. The authentication originally carried on the Fat AP itself is terminated. , roaming switching, dynamic keys and other complex business functions are transferred to wireless switches or wireless controllers.

3. Fit mode reduces the burden on a single AP and improves the work efficiency of the entire network. At the same time, due to the centralized management characteristics of the Fit AP solution, it can be easily expanded by upgrading the software version of the wireless controller to achieve richer business functions. All APs are installed with zero configuration. In addition to transmitting data, they can also monitor the wireless radio frequency environment of the entire network and detect illegal intrusions into APs and illegal guests.

4. Generally speaking, Fat can be used alone , each AP needs to be configured before it can be used. It is recommended for a small number of units, but the device structure is complex and difficult to centrally manage. Fit mode cannot be used alone and needs to be used with a wireless controller. It is recommended to use it when there are many Fit APs. It features "zero configuration" and all configurations are concentrated on the AC.

Extended information:

The access point refers to the device through which wireless local area network (WLAN) user terminals access the network. Nowadays, WLANs are widely equipped with APs. Users can access the wired network by connecting to the WLAN AP through a network card. There are two types of WLAN AP devices: FAT AP (fat AP, independent AP) and FIT AP (thin AP, centralized control AP).

The Fat mode and Fit mode of wireless AP are fat mode and thin mode.

Fat mode is used like a router

Thin mode just sends out wifi signals, plug and play, and needs to be used with AC management
