3.3 General Operations

3.3.1 Specifying Operational Mode

Fig. 20. Operational modes settings.
The AP supports 2 operational modes:
AP/Bridge. This mode provides both Access Point and Static LAN-to-LAN
Bridging functionality. The static LAN-to-LAN bridging function is supported
through Wireless Distribution System (WDS).
AP Client. This mode is for Dynamic LAN-to-LAN Bridging. The AP Client auto-
matically establishes bridge links with APs from any vendors.
In either mode, the AP forwards packets between its Ethernet interface and wireless in-
terface for wired hosts on the Ethernet side and wireless host(s) on the wireless side.
There are 2 types of wireless links as specified by the IEEE 802.11 standard.
STA-AP. This type of wireless link is established between an IEEE 802.11 Sta-
tion (STA) and an IEEE 802.11 Access Point (AP). An STA is usually a client
computer (PC or PDA) with a WLAN network interface card (NIC). The AP Client
mode is actually an STA.
WDS. This type of wireless link is established between two IEEE 802.11 APs.
Wireless packets transmitted along the WDS link comply with the IEEE 802.11
WDS (Wireless Distribution System) format at the link layer.
The relationships among the operational modes and the wireless link types are shown
in the following table:
