Often asked: What Is Sar Value In Smartphone?

SAR is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone. SAR provides a straightforward means for measuring the RF exposure characteristics of cell phones to ensure that they are within the safety guidelines set by the FCC.

What is the meaning of a SAR value in a cell phone?

  • SAR is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone. SAR provides a straightforward means for measuring the RF exposure characteristics of cell phones to ensure that they are within the safety guidelines set by the FCC.

What level of SAR is safe?

The SAR value is the rate at which the body absorbs this lost electromagnetic waves. According to US Federal Communications Commission (FCC), phones with a SAR level of 1.6 W/Kg for body or below are deemed safe.

What is harmful SAR value?

According to this standard, the limit of SAR is 1.6 W/kg over 1 g of body tissue [13]. SAR of mobile phone absorbed by humans is very dependent on the mobile network carrier, characteristics of mobile phone and antenna, antenna positioning, and the radiated power from the mobile phone [[14], [15], [16]].

Is 1.38 SAR value safe?

So how much SAR is better? Lower is better, although as noted earlier FCC in the US considers SAR level of 1.6W/kg good enough. So don’t worry if your phone has a SAR value of 1.2 or something like that even though most phones are nowadays in the range of 0.5 to 0.6.

Is 1.6 SAR safe?

Any cell phone at or below these SAR levels (that is, any phone legally sold in the U.S.) is a “safe” phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).

What is the difference between head SAR and body SAR?

A mobile device’s SAR rating is used to estimate the maximum rate of RF energy absorption by a user’s head and body when using the device. SAR is measured for placement of the phone next to the head and on the body. For example, the iPhone 6 has a Body SAR of 1.14 W/kg and Head SAR of 1.08 W/kg.

What happens if phone SAR value is high?

While there has been a lot of talk about the phones with high SAR (specific absorption rate) value can potentially damage the body at a cellular level, particularly when you hold the phones against your ears and talk on them, not enough attention has been paid by smartphone users to the damage that these devices the

Is mobile radiation harmful?

Cell phones emit low levels of non-ionizing radiation when in use. The type of radiation emitted by cell phones is also referred to as radio frequency (RF) energy. As stated by the National Cancer Institute, “there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans.

How can I reduce my mobile SAR?

How to Lower the SAR Level of a Cell Phone

  1. Use an earphone or a headphone with your cell phone whenever possible.
  2. Use speakerphones whenever it’s practical, for example, while driving.
  3. Keep calls as short as possible.
  4. Use special head phones that reduce SAR exposure.
  5. Avoid using your cell phone where the signal is weak.

How can I check my phone radiation?

How to check the radiation level of your smartphone

  1. Unlock your smartphone and open the ‘Dialer’
  2. Now, type the code ‘*#07#
  3. The smartphone will now automatically show the SAR rating of the smartphone.
  4. Go to the dialer app of your smartphone.
  5. Type ‘*#06# on the dialer.

Do SAR values matter?

While SAR values are an important tool in judging the maximum possible exposure to RF energy from a particular model of cell phone, a single SAR value does not provide sufficient information about the amount of RF exposure under typical usage conditions to reliably compare individual cell phone models.
