iPhone 6 vs Other Smartphones – SAR Value Comparison
Now it time to check the latest iPhones versus their main competitors:
After analyzing the above data, we can conclude that Apple don’t have a goal in producing low radio frequency exposing cell phones. Although all smartphones on the market have to comply with regulations, it’s obvious that some devices discharge more radio radiation as the others.
Apple Watch vs iPhone RF Exposure Values
Now here is how the smartwatch compares to its iOS companions
Conclusions
1. 42 MM vs 38 MM
Tests reveal that all Apple Watch models find themselves comfortably within the safe range of the Specific Absorption Rate limits! The 38 mm models have higher values when your head is exposed. That’s explainable because same radio emitting hardware has to fit a smaller case, thus rising radiation levels. However, the 42 mm scored bigger ratings for the Wrist test.
2. Apple Watch v iPhone
The smartwatch emits a considerable lower amount of radio frequency radiation compared to the iOS device. To be more precise, between 7.45 times (iPhone 6 lowest Head value vs Apple Watch 38 mm highest Head SAR rating) and 38.75 times less (iPhone 6 highest Body RF score vs Apple Watch 38 mm lowest Wrist SAR result).
How is RF Exposure Measured?
The Specific Absorption Rate or better known as SAR indicates the amount of energy soaked up by the human body during its exposure to radio frequency. For cell phone radio emitters, measurements are done, simulating the two most frequent cases of use, showing the impact on head and body.
Which are the SAR Limits?
In the US, the Federal Communications Community (FCC) limits radio frequency exposure to a SAR value of 1.60 watts/kilogram averaged over 1 gram/tissue. In other area, like Europe for example the limit is set at 2.00 wats/kilogram averaged over 10 grams/tissue. At first sight the European regulations could seem much harsher, however it’s important to note that averaging RF exposure at 10 grams, can flatten out hotspots and thus ‘hide’ radiation spikes.
