Hotspot help needed

I am working on this project of installing hotspot solution in 9 locations from a central location. I need help in choice of hardware and configuration.

My plans are like this.

Get 10 units of RB433UAH: One at the main location and the remaining 9 at the remote locations
1 server running Dmasoftlab’s Radius Manager.

That doesn’t tell us much. Will these units be connected with ethernet? will they be connected with wds wirelessly? mesh? how much coverage area? how many users???

They will be connected via wds (wireless)

You answered 1 question. Based on that answer, you should consider units with dual radios.

50M radius in each location
