Protecting the Phone

Optimizing Total Radiated Power (TRP)

In addition to providing protection for your phone from unnecessary damage due to being scratched or dropped, Pong protects your phone in another very important way. The transmission power of your cell phone is called Total Radiated Power (TRP). The maximum TRP of most modern cell phones, as measured in dBm (30 dbm=1 Watt), ranges from 24-33 dBm, with 27 dBm being average. Since TRP is directly related to the ability of your phone to communicate with the cell tower, it is important that external devices such as cell phone cases preserve TRP as much as possible.

Any case, cover, or device that you place upon your cell phone is likely to negatively impact TRP. This is especially true for other radiation devices that "contain" or "shield" radiation from the user and, consequently, can reduce TRP by over 90%.

In contrast, laboratory testing confirms that the typical performance of a Pong case will result in TRP changes of +/- 2.5 dB. So Pong is the only cell phone case has been proven to actually increase TRP.

We are so confident you will not notice a reduction in signal strength that we offer you this Pong Pledge:
If you notice a loss of cell signal from using your Pong case, simply return the case to us within 30 days of receipt and Pong will refund your purchase price. No questions asked.
