Networking and applications

Fit AP networking (AP mode)

In this networking scenario, the AP functions as a fit AP. The AC is responsible for user access, AP go-online, AP management, authentication, routing, security, and QoS. Huawei AC products include the AC6605, AC6005, ACU2 (with S7700, S9700, or S12700), S5720-HI, S7700 (with X1E board), S9700 (with X1E board), and S12700 (with X1E board).

Fit AP networking (WDS mode: Point-to-Point)

Fit AP networking (WDS mode: Point-to-Multipoint)

In this networking scenario, the AP connects two or more independently wired or wireless LANs through wireless links to construct a network on which users can exchange data. In Wireless Distribution System (WDS) mode, the AP supports Point-to-Point (P2P) and Point-to-Multipoint (P2MP) networking modes. With 5 GHz and 2.4 GHz frequency bands, the AP can implement wireless bridging and access functions.

Fit AP mesh networking

In this networking scenario, APs function as Mesh Points (MPs) and are fully meshed to establish an auto-configured and self-healing Wireless Mesh Network (WMN). APs with the gateway function can work as the Mesh Portal Points (MPPs) through which the WMN can provide access to the Internet. Terminals connect to APs to access the WMN. The WMN uses dedicated mesh routing protocols to guarantee high transmission quality and is more applicable to situations that require high bandwidth and highly stable Internet connections.

Fat AP networking

In this networking scenario, the device functions as a Fat AP to implement functions such as user access, authentication, data security, service forwarding, and QoS.

Cloud AP networking

In this networking scenario, the device functions as a cloud AP and works with the Agile Controller-Campus on the same cloud for user access, AP online, authentication, routing, AP management, security, and QoS. An enterprise can choose to use the Portal authentication server integrated in the Agile Controller-Campus or the authentication server deployed by itself.
