So the power delivered by a low frequency radiation comes in a great number of small packets, while the same amount of power carried by an higher frequency radiations is composed by few large packets. This is the reason why high frequency radiation is more harmful than lower frequency radiation .
Read moreWhat is RF in cellular?
A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication, if one is discussing wireless electronics. … RF waves occur naturally from sun flares, lightning, and from stars in space that radiate RF waves as they age.

The safe limit for a mobile phone user is an SAR of 1.6 watts per kg (1.6 W/kg), averaged over one gram of tissue , and compliance with this limit must be demonstrated before FCC approval is granted for marketing of a phone in the United States.
Read moreWhat does RF mean in telecom?
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).
Read moreWhat is RF explain?
RF is short for radio frequency . RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that is then able to travel, or propagate, through space.
