Apple's 2021 "iPhone 13" models may not include support for both highband and low-band 5G connectivity, with the future models potentially shipping with compatibility for either the extremely fast mmWave or the more resilient sub-6GHz spectrum. Apple's 2020 iPhone models will include 5G support, with the "iPhone 12" range expected to use 5G modems sourced from Qualcomm. But while speculation for the inbound iPhone generation is intensifying, some attention is being turned to the 2021 model, plausibly called the "iPhone 13." Apple is considering the possibility of producing a version of the iPhone using a single 5G band. While the iPhone 12 collection is anticipated to work with both sub-6GHz signal as well as mmWave, giving customers the full usage of 5G, Apple is entertaining the thought of including support of one or the other "for specific markets."
