wAP ac channels 5gz

Hello, is posible to repeat the AP signal to three devices from ONE wAP ac ?? In documentation I see it have 3 5gx channels.

Mi need is to create a hostspot with 3 wAP ac like this:


RB2011iLS-IN (main Hotspot router CAP’s Manager)
|
|
|
(2,4GZ clients ) wAP ac(MAIN)--------repeater 5gz---------wAP ac(first)(2.4GZ)--------clients
|
|
repeater (5gz)
|
wAP ac(secondary)(2,4gz)----clients


is this the correct way?? Thanks in advance
