Hi, currently i have installed and run my mikrotik perfectly. Now i am thinking of doing some public hotspot in my area using mikrotik. Now my mikrotik which is connected to internet are broadcasting signal using an outdoor AP (not wireless card). And the public hotspot that i am thinking of need to get the signal from my main mikrotik (which is connected to internet) and broadcast the signal in their own area. About the authentification, authorization and accounting issue, how should i do? Could i just set it on my main mikrotik, or do i have to add another mikrotik on the hotspot side?
Hi,
You can use Mikrotiks internal database or use the Hotspot Manager (Beta). You also have to check the recommended client limit of your AP and the distance from your MT router.
If you intend to maintain an AAA server for offering pre-paid or post-paid acceess, you can setup an external RADIUS server that should be able to provide you with a solid authentication/accounting/authorization.

Hi, thank you for your kind reply. I am thinking of setting up an external RADIUS server for AAA purpose. Any recommendation on which kind of server should i use? Please tell me one with an easy setup because i am really new in this field 
Do i have to put my AAA server behind of my main mikrotik router (which is connected to internet) or should i put it at the public hotspot area? Thank you…
I personally sugest FreeRADIUS.
You could put the server in the place which is visible from your HS gateway.

Im a newbee too here, and we just setup a mikrotik server ,but havethe same problem authenetication and billing do we need to setup an remote billing server comp?? what is “HS” gateway and were is it placed?
if you only have one gateway you dont need radius, basically radius is for distributed system where there is multiple gateways to internet. the built in AAA will do what you need, however its attribute are limited and you may want to be more advanced.
hope it helps
