What is frequencies for radios

The electronic field irradiates from an area of increased tension to one of less voltage. In RFID , it is important to be conscious of both fields that make up electromagnetic waves.

This is because RFID tags are going to use as much electric field as magnetic field to communicate their information, depending on the frequency they are using. When a reader emits radiofrequency signals , it causes variations in the electric and magnetic fields. This coupling is known as inductive coupling. Inductive coupling is the communication process used by LF and HF passive tags. Garage door openers, alarm systems , etc.

Radio controlled cars : Around 75 megahertz Wildlife tracking collars: to megahertz MIR space station : megahertz and megahertz Cell phones : to megahertz New MHz cordless phones: Obviously around megahertz! Air traffic control radar: to 1, megahertz Global Positioning System : 1, and 1, megahertz Deep space radio communications: megahertz to megahertz.

In the United States, the FCC Federal Communications Commission decides who is able to use which frequencies for which purposes, and it issues licenses to stations for specific frequencies. See How Radio Works for more details on radio waves. When you listen to a radio station and the announcer says, "You are listening to Megahertz means "millions of cycles per second," so " Your FM frequency modulated radio can tune in to that specific frequency and give you clear reception of that station.

All FM radio stations transmit in a band of frequencies between 88 megahertz and megahertz. This band of the radio spectrum is used for no other purpose but FM radio broadcasts.
