FM uses a higher frequency range and a bigger bandwidth than AM.
AM radio operates from 535 kHz (kiloHertz) to 1605 kHz. (New Zealand)
TAP – a kilohertz is 1000 oscillations per second.
When you tune the dial on your radio, the number changes by 10 kHz each time.
This means that each station has 10 kHz of bandwidth on which to broadcast.
FM radio on the other hand operates between 88 MHz (MegaHz) and 108 MHz, and your radio increments every 200 kHz.
TAP – A megahertz is 1,000,000 oscillations per second.
5G operates using Gigahertz. GHz are multiples of 100,000,000 oscillations per second, otherwise known as microwaves, 100 times more power in them as in MHz.
5 GHz WiFi channels & frequencies
As the 2.4 GHz band becomes more crowded, many users are opting to use the 5 GHz ISM band. This not only provides more spectrum, but it is not as widely used by Wi-Fi as well as many other appliances including items such as microwave ovens, etc.
It will be seen that many of the 5 GHz Wi-Fi channels fall outside the accepted ISM unlicensed band and as a result various restrictions are placed on operation at these frequencies.
TAP – WIFI is already being releasedn by BT and others using microwave frequencies. These will spoil sleep, interrupt many other bodily processes. Number one. Turn off Wifi at night, or when not in use. Turn off mobile phones at night. Disconnect all wifi devices like printers and switch them all off except when in use. Turn off all cordless phones including base stations. Let alone the 5G which will afflict you as you travel or walk through your local town, you might as well stop killing yourself in your own home. Avoid smnartmeters as long as you can. Then place a metal microwave blocking box around them if you are forced to have one.
