My Father-in-law and I have a rental building complex way out in the country. We were able to use SkyBeam a WISP to get access to the intenet. But what we really want to do is to boost its signal so that all the rental houses and buildings around it can have WiFi as well. The building that the WISP is run into is a Log house, and the other buildings are in a circle around the log house with the furthest away being 1/2 mile. We discussed burying a cat5 to each building, but this seems a bit labor intensive. My question is there a way I can do it wirelessly? To where every tenant can have access to WiFi from the one main router? And if this is possible what equipment do I need to buy? Trying to keep the budget to around $300
