Application Scenarios for WDS

Application Scenarios for WDS

In WDS application scenarios, APs can be deployed in the hand-in-hand or back-to-back mode.

Hand-in-Hand WDS Networking

As shown in Figure 13-5, AP1 is a single-band AP that works at 2.4 GHz frequency band; AP2 and AP3 are all dual-band APs. AP1 and AP2 use 2.4 GHz radio to set up wireless virtual links (WVLs), while AP2 and AP3 use 5 GHz radio to set up WVLs. AP3 connects STAs to the WLAN through the 2.4 GHz radio. On a hand-in-hand WDS network, AP1, AP2, and AP3 use different radios to set up WVLs.
Figure 13-5  Hand-in-hand WDS networking applications


In the figure, AP2 on 2.4 GHz radio functions as a leaf node for AP1 and AP2 on 5 GHz radio functions as a root node for AP3.

If the APs supporting dual 5G radios, such as the AP8130DN, are used as AP1 and AP2, you can set radio 0 of the two APs to the 5G radio.

Back-to-Back WDS Networking

In outdoor scenarios, such as school campus, plantations, and mountain areas, wired networks are difficult to deploy. When networks to be connected are far from each other or blocked by obstacles, APs can be cascaded as trunk bridges in back-to-back mode. This networking ensures sufficient bandwidth on wireless links for long distance data transmission. Figure 13-6 shows the back-to-back WDS networking.
