How important is the SAR value for you? Disclaimer Before we start, we want to make clear that we are not scientists nor doctors.
The information mentioned below is based on research over the Internet and expresses our personal opinion on the subject. Cell phones and radiation It is no secret that mobile phones use electromagnetic radiationeverybody knows that.
The radiation they emit to communicate with a cell tower us in the spectrum of radio waves. This means that the frequency emitted is between MHz, depending on our device and our carrier's network. WiFi, radars, and microwave ovens emit radiation in the same range. Radio waves Cell phones use radio waves to communicate with a cell tower, at the frequency we mentioned above.
These waves can "carry" our voice or other data through the air at the speed of light. These waves are transmitted in all directions. Furthermore, they can be absorbed or reflected by other objects of the surrounding environment.
As a result, when we talk on the phone and keep our cell close to our ears, a part of the emitted radiation is absorbed by the body. Antenna Each cell phone has at least one radio antenna. An antenna can receive or transmit the signal to the cell site.
Therefore, it is used as a transmitter to convert the phone's signal into radio waves. At the same time, it works as a receiver, to do the opposite.
Older cell phones used external antennas to transmit the signal. However, nowadays smartphones have built-in antennas for convenience. Connectivity One of the most common phrases we use regarding our cell phones is that we are "don't have a good signal.
As we already mentioned, cell phones are both transmitters and receivers. The magnitude of the received signal is the so-called "signal strength" of a mobile phone. We can check our device's signal strength at the top right corner of the cell phone.
It is usually represented by vertical lines, and the more we see, the better. Many variables can affect our Connectivity.5 Ways Technology Has Changed the Communication Field Technology is now the most important communication tool for organizations.
