>>. I should have caveated that, b11 is crummy. Here is the part that I love about the WISP's... Everyone is Opinionated to the Nth degree without explanation or possible understanding of why they have such an opinion..... and that is ok, as long as it is expressed in that context ...
As an engineer, I tend to dismiss all opinions, unless the person offering the opinion can offer an explanation which has some sound technical backing to support it.. Similarly, I also tend to dismiss the "I love it" opinions, unless they are backed up to the reason why. I am happy to see lots of options in the market space, no one can please everyone ..... FWIW, We use gear from many different mfg. each for their strengths, and not their weaknesses. We find that each of these products shine in the different ares of the three common requirement that everyone has.. Needs to be Good Quality, Fast Performance, and Cost Effective.. In regards to the debate about Freq., I will suggest to the OP that do a little bit of reading on the fade characteristics of different Freq. is, this is physics, and totally vendor agnostic, and this will greatly help you in gaining a better understanding of what is the difference one can expect between 24Gz/23GHZ/18GHZ/11GHZ/6GHZ etc.. for their deployment region.. (I agree with Steve, in regards to the missing context of rain zone, and I also agree with Mike H.. that Rain zone's are a rough guide, not an absolute ref ). I am a bit puzzled about Chuck M's comment about the Cost of License being high ? and a desire to purchase a 'bundle' which includes coordination etc... I would like to see if Chuck can elaborate a bit more on this... :) Happy Weekend.
