This is Apple’s $100 million state-of-the-art antenna test lab. It has 17 different antenna characterization chambers (or anechoic chambers) for measuring antenna performance.
Our anechoic chambers are connected to sophisticated equipment that simulates cellular base stations, Wi-Fi networks, Bluetooth devices — even GPS satellites. These chambers measure performance in free space, in the presence of materials simulating human tissue (“phantom” heads and hands, for example), and in use by human subjects. Over a one- to two-year development cycle, Apple engineers spend thousands of hours performing antenna and wireless testing in the lab.
Apple has also published several new pages on its website explaining smartphone antennas, including pages showing off the company’s antenna design and test lab. There’s a video of the lab here.
And here’s some more pictures:
