Apple internal antenna design laboratory known as the black lab, because it is a secretive department, and even some Apple employees do not know of its existence. The reason why Apple made public the existence of the laboratory, primarily to show that the apple in the antenna design and wireless testing is very serious. Apple's vice president of marketing Phil Schiller (Phil Schiller), said: \Without it, we can not design products. \Anechoic chamber and a middle arm, you can hold the living and the iPhone, iPad a variety of portable devices 360-degree rotation, the researchers can take advantage of an analysis software (irony is that this analysis software is a Windows XP system running) a device to detect radio activity of each.

In another project, Apple also took the equipment in the anechoic chamber people sit inside for 30 minutes, and then use specialized software to analyze and assess the performance of wireless equipment, equipment and human interaction.

Wireless product manufacturers must be certified by an independent testing laboratory, independent laboratory for wireless manufacturers of various products for testing to see whether they comply with the Federal Communications Commission to develop an acceptable radiation standards. difference is that in order to facilitate control of Apple product design and design changes, built his own laboratory. Each sample was identified as the official Apple product, are subject to repeated testing. (Of course,nfl sports jerseys, has its own laboratory also help Apple better security.) Caballero said that in the iPhone 4 become an official product, its prototype about two years after a total time various tests, and then Apple was to determine the final design. Caballero said: \\ during the visit,cheap nfl jerseys, Apple showed the reporters a hand full of man-made pickup truck, each artificial hands are holding a mobile phone iPhone 4.
