Telephone
If you've ever talked to anyone on a cell phone, or if you've ever used a pair of toy
walkie-talkies, or a bluetooth headset, or a cordless telephone, or Wi-Fi, then
you've used radio waves for two-way communication.
If you've ever used a GPS receiver in the car, or a wireless mouse or keyboard,
or a garage door opener, or listened to music or news on the radio, or watched
anything on TV, then you've used radio waves for one-way communication.
Electricity isn't used for communication, but it's used to power all of those other devices.

How do long wavelength radio waves communicate over big distances?
aids
Do satellites normally use microwaves or radio waves?
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
Can people disrupt radio waves by standing in front of them?
Yes. Radio waves are electromagnetic and are affected by anything that conducts electricity. The human body is mostly made of water, which conducts electricity and therefore affects radio waves. To demonstrate the effect, see what happens when you move around a radio tuned to a station with relatively poor reception.
What works by using radio waves to communicate with radio antennas placed within adjacent geographic areas?
