Hello,
I have a situation here that needs some help.
I have two area:
Area 1 has 700 people
Area 2 has 930 people.
Almost 99% of this people are ok to have installed in their house a dual band router that can connect to the access point (antenna array).

The challenge :

I want to setup an access point so people who live 1or 2 km around my access point can connect to it and receive internet using their home routers.
One each area, I have access to building rooftops that can be seen 9 km away (Clear LOS).


The two access points will be connected to the base station or backhaul station that is about 7 km away with a clear LOS too.

My question: can you guys tell me what type of tp-link radio I will need per access point ?
How many radio ? ( 60 users per radio for example)
What type of tp-link antenna ?
Can I use tp-link WDS feature from the base station to the access points ?
Thanks,
Karl
