RIM Execs Deny Apple Test Data on Signal Fade

The Research in Motion "BlackBerry Bold" device, as tested by Apple, appears to show the same signal fade issues as the Apple iPhone 4 when held in certain ways. RIM executives deny they have a signal reception problem.

"Apple's claims about RIM products appear to be deliberate attempts to distort the public's understanding of an antenna design issue and to deflect attention from Apple's difficult situation," say Mike Lazaridis and Jim Balsillie, RIM Co-CEOs. They don't specifically refute the Apple test data, though, which is odd.

They simply say "RIM is a global leader in antenna design" and say RIM "has avoided designs like the one Apple used in the iPhone 4 and instead has used innovative designs which reduce the risk for dropped calls, especially in areas of lower coverage."

Again, that doesn't specifically address the Apple test data.

Smartphone Antenna Performance: BlackBerry, Droid Have the Same Problem?

Apple says other smartphones, such as the BlackBerry Bold and Droid Eris, have the same problem with signal attenuation when the devices are held.

Mobile phone signal attenuation happens whenever a signal is obstructed, Apple notes. The density and composition of the human hand can cause attenuation to a greater degree than some other materials.

On a mobile phone, signal loss typically occurs when your hand attenuates the most sensitive part of the antenna. Apple even has put together videos demonstrating how different grips cause attenuation on many popular smartphones, not just the iPhone 4 and iPhone 3GS.
