Just want to mention, how are you planning on hitting the non-line of site locations? If there is an existing wireless network in the area, might be better to utilize their services instead.
The only thing I can say about non-licensed spectrum is that it is crowded... unless you have very exacting equipment, you might run into issues. Having said that, I find Wifi rather unreliable... if you are sticking devices up on a pole or a location that is hard to get to, you might want to consider a more commercial produce with purpose built management tools, etc...

Amazing info everyone. I can't thank you enough as to how much time you saved me. I will go over all the links and start my readings. In the meanwhile I have the following questions: - So, something in the order to 10 Mbps "full duplex" or whatever the term is for "both ways" should be very easily achievable using the equipments mentioned? - Has anyone tested this for telephony application? - How is the round trip delay usually? - Does very cold or hot weather have an effect on the operation? rain or thunder? (e.g. degraded bandwidth or lots of errors in packets?) , has anyone had the issue of directed "intentional" interference or other types of interference which would make this connection any less solid than a DSL or Rogers cable on daily or weekly basis? - What about NLOS solutions? Are there any viable product for that as well? Obstacles could be tree or buildings.
