If you know about smartphones, then you must have heard the name SAR Value or simply the value of SAR on Smart Phones. Maybe you have heard in many smartphone reviews or seen the writing on the back of the new smartphone box. That the SAR value of this smartphone was either this SAR value of that smartphone or the values should be higher or lower and so on. But have you ever wondered whether this SAR value is the thing or what or what is its need? What will happen if it is high or low or what will be good? Today, I will talk about this SAR value in just a few words. First of all,
What Is The SAR Value?
As we all know, all modern smartphones of today use electromagnetic radiation. All smartphones or ordinary mobile phones also have an antenna that controls all wireless communications on the smartphone. The smartphone also uses this antenna when connected to your WiFi network, connected to your Bluetooth device, and connected to your network provider’s tower. And as a result, every modern smartphone undergoes electromagnetic radiation. This is because the smartphone has to use radio web waves to protect its connection to wireless networks using this antenna. And 100% of the radiation that a smartphone sends to a wireless device or to a carrier tower never reaches it. For example, if 100% is sent, maybe 80% of it gets there and the remaining 20% is spread around the smartphone. For example
And the amount of radiation your smartphone radiates isn’t always the same. For example, when you use a lot of light on a smartphone or use it too lightly, the smartphone will emit much less radiation, and if you use too much heavy work or do too much heavy work, it will leave relatively high radiation. This is where the SAR value comes from, the full form of which is the Specific Absorption Rate or SARs. This is the rate of the residual radiation that your body absorbs. And the rate at which this residual radiation is absorbed is called the SAR value.
What Is The Function Of SAR Value On A Smartphone?
Now you may be wondering when this is a very common thing and is the case for all phones, why write it in a special smartphone box? This is because of the government’s decision in the country where the smartphone is being sold. Governments of different countries around the world have put different rules on SAR values in terms of smartphone sales. That is, the government of different countries has set a value that if the SAR value of your company’s smartphone is above that prescribed values, then you cannot sell that phone anywhere or the government of that country will not allow you to sell the phone.
For example, the SAR value limit kept by the Government of India and the United States is 1.6 W / kg tissue. Tissue refers to the tissue of the human body. This means that according to the Government of India and the United States, there are 1000 grams of tissue per human body. It can absorb 1.6 watts of radiation without any harm. These values vary according to different countries. That means, in order to sell a phone in India and the US, the SAR value of that phone must be 1.6 watts or less. The phone cannot be sold if the SAR value of a phone is higher than this.
How Much Does The SAR Value Matter?
By now you must have understood what this value is and why it is on a smartphone or not. But even more important, how much does this value matter for you or your everyday life when you use that smartphone? First of all, if you are worried that before buying a smartphone? You should first look at the SAR value of the phone very smartly and then buy the phone, then, to be honest, there is nothing to think about. Because, if the SAR value of the smartphone was even a little higher than the government-determined rate. Then the phone would not be sold in the market. The smartphone’s retail unit has come to market because the SAR value of the phone is OK and the lower the prescribed rate, and you can buy the smartphone.
In addition, radiation radiated from a smartphone will only Matter, when you are talking to someone holding the smartphone in your ear. Because, even if this radiation on a smartphone can do a small amount of damage to you, it is most likely that the damage is done to your head or your brain. Although modern smartphones are less likely to do any kind of physical harm to you today.
But none of us talk to the phone 24 hours a day. If we are ordinary people, maybe we talk on the phone for 2 hours or 3 hours a day. In that case, you don’t have to worry about the SAR value of the phone. In that case, you can totally forget about the SAR value. Yes, it is definitely better to look at the SAR value before buying a phone, and it is better to have this valueless, but there is no harm in the slightest.
The amount of radiation your smartphone radiates doesn’t always equal its rate. For example, when you use a lot of light on a smartphone or use it too lightly, the smartphone will emit much less radiation, and if you use too much heavy work or do too much heavy work, it will leave relatively high radiation. This is where the SAR value comes from, the full form of which is the Specific Absorption Rate or SAR. This is the rate of the residual radiation that your body absorbs. And the rate at which this residual radiation is absorbed is called the SAR values.
