Looking for Fixed Wireless Internet Info?

tukkayoot asks: "I live in a rural area where cable and DSL aren't available. I want some form of broadband Internet access that doesn't require that I move. There is an ISP in my area that offers fixed wireless, but they make no effort to market it to residential users (even though they claim the service is available). Unfortunately, searching the Internet seems to yield more information about starting a WISP than what an ordinary Joe like me should be doing to educate myself about this service, as a customer. I don't have high confidence in the ISP to walk me through the entire process, so is there anybody out there that can direct me to a resource on consumer wireless related issues, like how I should go about receiving a signal when my house is surrounded by lots of fairly tall trees?"
