Re: Presonus Digital Mixer Questions
Of course, even at 5Ghz, the atmospheric attenuation of ~.3db/km in a tropical downpour, is inconsequential relative to the other factors (such as obstructions, antenna gain, cable losses, etc.)
I was under the impression that, all else equal, higher RF frequencies had higher attenuation in air (kind of like sound).
I found a chart that shows this (look at the second one). Atmospheric absorption could easily be 4 times as bad for 5GHz vs 2.4GHz.
The 802.11 spec is quite interesting. It seems that recently 802.11a was expanded to include 3.7GHz with a rather ridiculous range. Maybe Presonus should recommend that one, even though I've never seen a device that uses 3.7GHz 802.11a!
