Bet you didn't know that your iPad 3G's transmission strength is reduced by up to 75% when used within less than half an inch from any solid object. The drop in transmission power is to protect your body from electromagnetic radiation. Unless you're using a Pong iPad Case ($80-$100), plan on experiencing subpar transmission strength at all times. Pong iPad Cases feature a unique design that ensures your device's antenna is exposed at all time. Even more, each cases are equipped with Pong's patented antenna technology that redistributes the electromagnetic radiation below FCC limits. This means you'll enjoy optimized transmission power without worrying about being overexposed to electromagnetic radiation.
