Figure 1-1 Fit AP networking (AP mode)
In this networking, 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 products that
provide the AC function include the AC6605, AC6005, ACU2 (with S7700, S9700, or
S12700), S5720HI, S7700 (with X series board), S9700 (with X series board), and S12700
(with X series board).

Figure 1-3 Fit AP networking (WDS mode: point-to-multipoint)
In this networking, 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. Supporting 5 GHz and 2.4 GHz frequency bands, the
AP can implement wireless bridging and access functions.

Figure 1-4 Fit AP mesh networking
In this networking, 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 scenarios that require high bandwidth and highly stable Internet connections.

Figure 1-6 Cloud AP networking
In this networking, the device functions as a cloud AP and works with the Agile Controller-
Cloud Manager 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-Cloud Manager or the authentication server deployed
by itself.
