Apple probably bring single-band 5G in iPhone 13 by 2021
According to DigiTimes, 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, Taiwan-based sources believe Apple is entertaining the thought of including support of one or the other "for specific markets."
Upcoming planning, goals & model fitting
Apple's 2021 "iPhone 13" models may not include support for both high-band and low-band 5G connectivity, a report claims, with the future models potentially shipping with compatibility for either the extremely fast mmWave or the more resilient sub-6GHz spectrum. It is largely believed that Apple's 2020 iPhone models will include 5G support, with the "iPhone 12" range expected to use 5G modems sourced from Qualcomm.
Conclusion
The decision to provide partial 5G support could potentially allow Apple to offer devices that offer at different connectivity speeds, depending on what the market offers in terms of existing infrastructure, as well as the needs of customers. Sub-6GHz 5G is resilient and able to operate at long ranges, unlike mmWave, but it won't provide much of a speed boost over LTE connections. But while speculation for the inbound iPhone generation is intensifying, some attention is being turned to the 2021 model, plausibly called the "iPhone 13."
