Re: WISP Startup Everyone here has some very good suggestions.
You should put up some 5ghz gear if you have perfect line of sight it works best.
Mikrotik's Cloud Router looks very nice. They even have a high resolution picture of the board so you know what your getting part wise, It all seems pretty good.
Its got a little LCD screen on it too.
We mostly use Cisco gear for our networking. We use Cisco 3825, Cisco 3845, Cisco 3845 routers. And Cisco many types of switch's. (Not the home or small business ones).
Pfsense is a good choice if you want to use a pc based router. There are many operating systems you can run, Mikrotik, Debian.
Openwrt isn't bad either if you use JFS file system, add in fsck and a few other utility and put it on a flash card.
I'm actually thinking of running a free wi-fi service in the city limits in the 5Ghz band due to LOS. Most subscribers can't get perfect LOS so 2.4 sounds welcoming but 900 would be perfect!
5GHz will really limit the number of devices that can actually use the service though. Devices tend to have B/G support more than they have A support.
