In the U.S. market, the newly launched iPhone 17 Pro and iPhone 17 Pro Max are equipped with antenna windows positioned at the top of the devices. These windows are specifically designed to facilitate the transmission of mmWave 5G signals, ensuring a seamless and high-speed connectivity experience. Notably, the standard iPhone 17 model does not incorporate this antenna window, and the iPhone Air also eschews this design feature, as it lacks support for mmWave 5G technology.
