We are planning on running a small WISP provider +500 clients, for a start what gear/requirements do you recommend. Thanks
I think you should be better off understanding the basics of wireless communications at first. search in the forum. but basicly you will need
Base station antennas (sectoral)
Base station radios ( more than 20 depending on your load 500 clients)
CPE devices (either MT or third brand. MT CPE devices gives you more flexibility but third brand is cheaper)
Towers, boards, computers, backhauling and etc..
go search.
