WebDec 8, 2014 · As I understand it, radio transmission involves modulating a carrier wave with the signal you wish to send. The bandwidth is the range of frequencies that are contained within the signal. I have read that if the range of frequencies is 4.5kHz then you need 4.5kHz either side of the carrier wave giving a total bandwidth of 9kHz. WebJul 8, 2024 · When a radio wave hits the ionosphere, the energy created by the free electrons, as a result, causes the radio waves to be repelled or reflected. So, we know that radio waves up to 40MHz won’t pass through an ionized layer in the atmosphere. Remember that we explained the perceived limitations of radio transmissions before Marconi’s discovery.
