Ever noticed that slapping a case on your iPad somewhat restricts its 3G signal? That’s because your iPad is equipped with a clever proximity sensor that reduces the power of its 3G sensor by as much as 75% when it detects your device is close to your body, thereby reducing your exposure to harmful radiation.
Unfortunately the sensor isn’t clever enough to work out the difference between your body and a protective case, so as soon as it comes into contact with a case its 3G signal is restricted. However, this particular case from Pong Research not only prevents your iPad from limiting its 3G signal — giving you faster, more reliable data — but it also redistributes its radiation away from your body.
The $100 Pong Case and Cover for iPad 2 promises to be the only solution that reduces SAR up to 80% below FCC limits while improving 3G performance and connectivity:
Using any case with your iPad 2 can reduce 3G transmission power by up to 75%! Pong™ is the only solution proven in Federal Communications Commission (FCC) certified laboratories to protect iPad 2 users from electromagnetic radiation while preserving TRP (Total Radiated Power) of the iPads, and thus the transmission strength.
So how does Pong do it? Well, not only does it leave a hole next to your iPad’s proximity sensor, but it also features an integrated circuit board that takes the harmful radiation emitted by your device and redistributes it away from the body.
And the Pong case really works according to Ars Technica, who has tested out its claims and confirmed that it works as promised.
