Microwave and weather don't mix well. You will get drop outs if it's raining really bad or there is some heavy fog all the time. But drop outs mean slow connections during inclimate weather. Not necessarily broken connections. During a feasibility study one would want to be accurate and honest. You could say it's going to cost 50,000 just to shut them up, but that wouldn't be honest. I am not going to give you an estimate because that is impossible from here. For instance I would need the fibre capacity of your city and I haven't a clue what operting frequencies you have. In the US we can use 2.4 Ghz microwave without a license and with a license we can use 2.4Ghz at high power applications. Depends on line of sight also. For instance if you have to uild a 100 foot tower to get line of sight at each location your cost just went up 30 to 40 k. This entirely depends on if copper or fiber is available. The gigibit microwave connections require a different frequency band and a license in the US. Some go up to 16 t1 but their freqency requires specialized handling or some knowledge in RF. It will cook you like a hot dog. I'll post some vendors, you can read their products and estimate a price.

Those are a few vendors outside the use.

Something I don't have personal experience with, but is gaining momentum is Free Space optics. http://www.fsona.com/ Seems these things would be great for extreme requirements. Just pop one up in a window and beam across the street etc. Bring alot of Cash.
