Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat is radio frequency used for?
Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones , to name a few. Radio frequencies are also applied in carrier current systems including telephony and control circuits.
Read moreWhat is radio frequency and how does it work?
How radio frequency works. Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted . One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.
Read moreWhat is radio frequency signal?
A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication , if one is discussing wireless electronics. Radio waves are a form of electromagnetic radiation with identified radio frequencies that range from 3kHz to 300 GHz.
Read moreWhat is the advantage of using a high frequency response?
The high frequency response of multistage amplifiers theory is used for high gain as well as high bandwidth . 2.
Read moreWhy HF communication is important?
This works particularly well over water, and HF Surface Wave can be used to communicate between ships hundreds of miles apart. HF Surface Wave provides a more robust service than Skywave and is particularly suitable for higher speed operation . This can make it an excellent choice for Naval Task Group communication.
Read moreWhat is an example of HF?
Aviation air-to-ground communications . Amateur radio. Shortwave international and regional broadcasting. Maritime sea-to-shore and ship-to-ship services.
