Apple’s latest iPhone 12 models are the first to feature 5G connectivity, but access to ultra-fast mmWave bands are limited to customers in the U.S.
Support for speedy 5G connectivity was a central selling point when Apple announced the new handsets on Tuesday. According to a support document, however, access to bands that offer the greatest data transfer potential are limited to certain models.
As noted by Apple, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max and iPhone mini integrate Qualcomm radios compatible with the n260 and n261 bands, which operate at 39GHz and 28GHz, respectively. Known as mmWave, these high-frequency bands feature wavelengths that can be measured in millimeters instead of centimeters or larger, and provide ample data transfer capability with bandwidths exceeding 3GHz.
While Apple’s 5G-compatible iPhones support a wide range of bands, including those that operate in the robust sub-6GHz spectrum, mmWave is restricted
