Wireless ISP

Hi,
I have same question about becoming ISP. What is needed to setup ISP for about 200 subscribers? What equipment I need? I have some knowledge with Mikrotik so I would like to use that equipment.
Network should look like this: I already have a deal to get 100/100 Mbit link, I want to setup five wireless stations on the same building and users will connect to this stations with their equipment on 5 Ghz. I don’t know how to manage users, packets, speed …? Can I do this on Mikrotik with Radius or I have to have server to manage this. Can I accept this WAN link with Mikrotik RB750 and after that have one switch to which I will connect this wireless station?For wireless station I plan to buy airmax sector titanium am-m-v5g,Rocket M5 titanium, Ubiquiti 5 port switch.
Thank you

Direct way to go bankrupt.

First make a plan. How many users, what KIND of users (gamers, downloaders, only web browsing etc…).

What kind of traffic do you expect? What overbooking factor are you going to use.

and many more questions, before “buying” any equipment.

First you set priorities, investigate what you need, and only THEN decide what you need.

This may sound harsh.

If you don’t know the basics then you are going to fall.

Now the question.

Why do you want to become a wisp?
