What are Radio Frequency Waves?
Electromagnetic energy pervades the entire uni-verse, and radio frequency waves are part of the electromagnetic spectrum. These waves oscillate at a unique frequency which is expressed in cycles per second, or Hertz, and is analogous to the musical pitch of a plucked guitar string. Radio Frequency Data Communication (RFDC) uses RF waves as a medium for transmitting and receiving information. The RF waves used in data communication oscillate at approximately 400, 900, and 2400 million cycles per second. This places RF waves at or near the frequencies used in RF radio broadcasts, and they are impossible to detect except with an RF receiver. They are completely harmless at these levels.
