Network topology suggestion for wisp???

i want to change my network topology. Now most my APs and Stations re Bridge mode, Some of the stations re in routed mode .( ı use 9 main AP in 5 ghz band - 70 locom5 station attached to main 9 APs and 50 AP in 2.4 ghz band attached to 70 locom5 stations) You Can see that in attached file. So in peak times my clients network is slowdown. I guess this is bcz broadcast and arp packets. If i change my network topology to Vlan in tower side is it helpful for me .

I wait yours suggestion

Thank you in advance

Is there a logic error in the topology ???
