“Led by Ruben Caballero, a senior engineer and antenna expert at Apple, the tour gave about 10 reporters and bloggers a peek at Apple’s custom-built wireless testing lab, which consists of several anechoic chambers to measure frequency of each device in various settings.
Apple called the lab a “black” lab because it was a secret facility that even some employees were unaware of. The company made the lab public to show the world that Apple takes antenna design and wireless testing seriously.
“This is the most advanced lab for doing RF studies that anyone in the world has,” said Phil Schiller, vice president of marketing at Apple. “The designs we do wouldn’t be possible without it.”
Each test chamber is lined with blue pyramid-shaped styrofoam designed to absorb radio-frequency radiation. A robotic arm holding gadgets such as iPads and iPhones spins 360 degrees while a piece of analytics software (ironically running on Windows XP) visualizes the wireless activity of each device.
“To do the most challenging design in the world, this is what we have to do,” said Bob Mansfield, Apple’s senior vice president of Macintosh hardware. “This is hardcore stuff.”
