Radio frequency how does it work

The term «energy» refers to the radio frequency signal strength. The basic unit of energy is the watt. However, in the RF world, we talk about power in terms of milliwatts, shortened to mW.

Performing calculations using the decimal form of milliwatts can be tedious, so the standard is to calculate in decibels, or in powers of ten. In the case of RF calculations, energy levels are generally mentioned as 1mW decibels, and the abbreviation «dBm» is used. How does radio frequency work? Radio waves are electromagnetic waves and they travel at the speed of light in free space. In the equation you can see that, if the RF frequency increases, its wavelength decreases.

Have you ever wondered what all of those different names really mean? What's the difference between them? A radio wave is an electromagnetic wave propagated by an antenna. Radio waves have different frequencies , and by tuning a radio receiver to a specific frequency you can pick up a specific signal. 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. Moreover, RF can safely treat more patients with different skin tones without risking permanent discoloration. Of course, the safety and efficacy of non-surgical RF or any treatment depends on the experience and skill of the person providing that treatment more on that later. However, there is no conclusive evidence that RF exposure increases cancer risk in humans, even in people regularly exposed to higher amounts of RF for their jobs.

Both the American Cancer Society and Federal Communications Commission have issued extensive reports on possible impact of radiofrequency exposure. Many other studies have failed to find evidence for a link to cancer or any related condition.

The main known risk associated with RF is the potential for burns from the thermal heating effect for people exposed to high doses—for instance, those who work around radar equipment without proper protection.

With the above information, you may ask, if exposure of high doses of radiofrequency can cause burns, will non-surgical RF treatments hurt me?

If you are a good candidate for the procedure and it is performed correctly, no. The radiofrequency used in non-surgical treatments is different from that emitted by your microwave or cell phone, or radar equipment—the radiofrequency in skin tightening treatments is highly controlled. FDA cleared technologies use equipment that allows the practitioner to monitor and control the device during treatment to ensure that targeted tissues reach the optimal temperature to induce new collagen production and cell regeneration without overheating.

Clinical studies have demonstrated an excellent safety profile on RF procedures for skin tightening, whether it be for vaginal rejuvenation , facial skin tightening , or body contouring. Along with effectively lifting and tightening tissues without surgery or downtime, one of the greatest benefits of RF treatments, when performed correctly, is that post-procedure recovery is very quick and easy. Side effects are typically minimal and short-lived, limited to mild and temporary swelling, redness, and tingling, depending on the treatment.
