My point was simply, let 5Ghz reign the outdoors and let 2,4Ghz reign the indoors!
I totally agree with that!
That's exactly what I am doing for my network. 2.4GHz for my home and 5GHz for my p2p links on the roof.
But as a former poster also already pointed out that is just a pale dream coming from a small WISP!
(By the way, you make it sound like all WISPs are big multimillion dollar companies that can afford paying large frequency fees. This is very often NOT true! ;D All companies have to start somewhere!
I understand that WISPs are not multi-million dollar companies. If they were they probably wouldn't use 2.4GHz and 5GHz to build their backbone in the first place (why use a band that at any time you can have problems - since anyone can play there and cause interference - if you can afford a private band that only you are allowed to use?
But the thing is, when 'business' gets in the way, then many stuff get distorted in the name of business and money (a relevant example might be the internet as a whole - today the internet is MUCH different than it used to be 10 or 15 years ago - depending on your ideology and how you view the world the internet got worse because business got in the way).
And I've seen WISPs that don't know what the hell they are doing! Causing more (RF) problems than wireless communities (which I am a part of and consider it more useful than any WISP - even though we call ourselves amateurs - which in my language it translates to 'Ερασιτέχνες' which means literally means 'lovers of art'. So the bottom line is that we care about the band because we love what we are doing, not because we make money off of it).
I understand that getting your own frequencies might be quite expensive depending on the country you are on, but as any other company that needs to get the proper permissions from government (or whatever authority) to conduct business, that should be the case with WISPs IMHO.
Otherwise I can only imagine a future where in the name of money and business you will ruin 5GHz as well
