About Simultaneous Body SAR: What You Need to Know

Specific Absorption Rate (SAR) is a measure of the amount of radiofrequency (RF) energy that is absorbed by the human body when exposed to wireless devices such as mobile phones, laptops, and tablets. SAR values are used to ensure that these devices meet safety standards and do not pose any health risks to the user.

In recent years, concerns have been raised about the potential health effects of exposure to radiofrequency radiation from wireless devices, particularly when multiple transmitters are active at the same time. This has led to the development of the concept of “Simultaneous Body SAR”, which is a measure of the amount of RF energy absorbed by the body when multiple wireless transmitters are active at the same time.

In this article, we will explore the concept of Simultaneous Body SAR in detail, including its history, testing procedures, and the latest research findings.

 

History of SAR Testing

SAR testing has been around for several decades, dating back to the 1980s when researchers first began to investigate the potential health effects of cell phone radiation. At the time, there was a great deal of uncertainty about the long-term effects of exposure to electromagnetic radiation. Some researchers were concerned that the radiation emitted by cell phones could cause cancer, while others argued that the radiation levels were too low to have any significant impact on human health.

To help settle the debate, researchers developed a standard method for measuring SAR, which involved using a phantom body that simulated the absorption characteristics of human tissue. The phantom body became known as the Specific Anthropomorphic Mannequin (SAM), and it’s still used today for SAR testing.

The Design and Limitations of the SAM Phantom

The SAM phantom is designed to represent the body of an average human being. It has specific dimensions for the size and shape of the head, as well as the thickness and composition of the skin, muscle, and other tissues. The SAM has a skin surface that is made of a material that simulates the dielectric properties of human skin.

During SAR testing, the wireless device is placed in different positions on the SAM phantom, including the front, back, and sides of the body. The SAR value is measured in watts per kilogram (W/kg), and represents the rate at which RF energy is absorbed by the tissue in the body that is closest to the device’s antenna.

The SAR Measurement Procedure

After the wireless device is placed on the SAM phantom, a radio frequency (RF) signal is sent to the device at its highest power level, and the SAR value is measured. The SAR measurement is done using a specific test protocol that involves a reference measurement, an area scan, a zoom scan, and a drift measurement. The same procedure is done with all test positions and wireless technologies for mobile phone testing.

Simultaneous Body SAR Values

In recent years, there has been growing concern about the potential health effects of exposure to radiofrequency radiation from mobile phones, particularly when held close to the body. SAR testing is an important tool for assessing the potential health risks associated with this type of exposure. The SAR measurement procedure and phantom design aim to provide a standardized and repeatable method for measuring the amount of RF energy absorbed by the body when using a mobile phone.

As with the head SAR measurement, the simultaneous body SAR value is an important metric to consider. This value represents the amount of radiation absorbed by the body when multiple transmitters, such as cellular and WLAN signals, are active simultaneously. To measure this value, SAR testing is performed on both the cellular and WLAN signals separately, and the highest reported SAR result is selected for each test position. These results are then summed together, assuming the antennas are co-located, to determine if the simultaneous SAR is within the safety limit of 1.6 W/kg in the USA.

If the simultaneous SAR value is over the limit, the two results are summed again using the Combined Fast SAR feature of ComSEMCAD X software. This is because the hot spots of the two summed measurements may not be exactly on top of each other, so using the software can produce a more accurate result. If the final value is within the safety limit, the phone is considered safe for use.

It is important to note that SAR values are not the only factor to consider when assessing the potential health effects of mobile phone use. Other factors such as duration of use, distance from the body, and specific absorption rates of different tissues should also be taken into account.

Conclusion

SAR testing is a valuable tool for assessing the potential health risks associated with mobile phone use. The use of a standardized phantom and testing procedure allows for accurate and repeatable measurements of the amount of RF energy absorbed by the body when using a mobile phone. It is important to note that SAR values are just one factor to consider when assessing the potential health effects of mobile phone use, and consumers should take steps to minimize their exposure to radiofrequency radiation, such as using hands-free devices or keeping the phone away from the body.

FAQs

Q1. What is the difference between head and body SAR measurements?

Head SAR measurements are used to assess the potential health risks associated with the use of mobile phones near the head, while body SAR measurements assess the risks associated with using the phone near other parts of the body.

Q2. Are SAR values the only factor to consider when assessing the potential health risks of mobile phone use?

No, SAR values are just one factor to consider. Other factors such as duration of use, distance from the body, and specific absorption rates of different tissues should also be taken into account.

Q3. What is the safety limit for SAR values in the USA?

The safety limit for SAR values in the USA is 1.6 W/kg.

Q4. How can consumers minimize their exposure to radiofrequency radiation?

Consumers can minimize their exposure to radiofrequency radiation by using hands-free devices or keeping the phone away from the body.
