As shown in Figure 324 , Radio 1 of MP 1 joins the mesh through the MPP. In this case, only Radio
1 can provide access for downstream MPs. Radio 2 cannot automatically access the mesh and
provide the mesh service.
Figure 324 Two radios on different meshes
If an MP supports three radios, you can configure Radio 1 as the uplink interface, Radio 2 as the
downlink interface, and Radio 3 as the multi-beam antenna. To utilize the dual-radio resources on
MPs, you can establish the network as shown in Figure 325 . In such a network, when Radio 1 of
MP 1 accesses the mesh, Radio 2 on MP 1 also automatically joins the mesh. In this network, you
should apply the same mesh service to both Radio 1 and Radio 2. For more information, see
" Tri-radio mesh configuration example ."

Subway WLAN mesh deployment
A subway is an important traffic means for a modern city. In a subway system, control information must
be sent to trains to effectively manage trains and provide various services to customers.
As shown in
Figure 326 , a subway WLAN mesh solution has fit MPs deployed along the rail, which are
managed by the same AC. A train MP (fat AP) continuously scans new rail MPs (fit APs), and sets up
active/dormant links with the rail MPs with the best signal quality. The active mesh link is used for data
transmission, and the dormant mesh link acts as the backup link.
