TUAW has a story today about a new iPad case from Pong Research, which the manufacturer claims is designed to boost your iPad’s 3G signal, which is the opposite effect that using a case would normally have on the signal, as according to a story on Ars Technica, also quoted by TUAW, a normal iPad case would, as a rule, weaken the 3G signal emanating from the iPad, and mean a slower data rate. As far as the Pong Research case is concerned, it ensures that your iPad 3G signal will not be weakened by being covered, by placing a small hole right next to the proximity sensor, which has been installed on the iPad in order to protect the user from exposure to radiation from the 3G signal, by weakening the signal if the user gets too close to their iPad. TUAW says that the case has also been fitted with an integrated circuit board, which redistributes any excess radiation away from the user’s body. According to the Ars Technica report, the case actually does work on both counts, so if you like the sound of it, click here to order: Pong Products - Pong™ Case and Cover for the iPad 2
