Electromagnetic Spectrum over the Years

by | Sep 3, 2020 | Blog

I found some older graphics showing how folks in the past viewed the RF spectrum. Obviously, very little has changed over the decades… other than how efficient we are at USING the spectrum in all our communications.

This is how they saw the RF spectrum allocations back in the day.

Here is a current FCC version… and to think Wi-Fi is only a very small, single slice of all this RF spectrum! – Boggles the mind.

Or, if you’d rather read text versions… and you need something to help with your insomnia, you can try this version from the FCC’s website of RF spectrum allocations.

This is just page 1 of 172… Enjoy!
