It is awesome, and explains Free Space Path Loss in a simple way.

Well, I was thinking, what would it be like for 6GHz* and also for 60GHz. And, while I am there, how about calculating for 1GHz (approximation of sub-1GHz) as well?

A fillable copy of the calculation spreadsheet is available by emailing amy@nc-expert.com

Enjoy.

*Francois has updated his site for 6GHz as well.

**The reason I added a 7GHz line, is 6GHz actually goes from just below 6GHz to just above 7GHz. So, if you are using one of the higher channels, it is more applicable to 7GHz than 6GHz.
