Subject: Using PMR446 as a test for a wi-fi link

Hi All

I have a (just) non line of sight link of 2.5km to link 2 buildings with a 5GHz solwise type link.

A PMR 446 - PMr446 link works so I thought thta might establish the free space loss in real life of this path Then some more calculations could be made to allow for the 5Ghz frequency (instead of 446MHz)

The link would have 2 x 23 db antennas - so gains on the antennas, loss on the higher frequency, loss on the inreased bandwidth etc.

Has anybody got any comments on how good an idea this is?
