Apple’s September 14th event introduced the new iPhone 13 and what caught my attention was a brief mention by Tim Cook of “new bands and antennas” for the iPhone 12 successor. Looking more closely at the specs shows that the iPhone 13 adds support for 26 GHz mmWave (n258), which builds on the 28 GHz and 39 GHz support (n261 and n260, respectively) my iPhone 12 Pro Max has.
I spent a lot of time characterizing mmWave performance during my LMDS days at Wavtrace, and I can tell you that rain and foliage are not kind to the higher frequencies, so the inclusion of 26 GHz in the new phones should make mmWave 5G more likely to work well especially as Seattle turns toward the rainy season.
This post serves as a brief summary of the technical specifications of the many radios in the Phone, iPad and the Apple Watch and as index for easier deeper exploration into each. Most of these are very broad categories (for example, there are many types of Bluetooth with differing data rates) and I’ll be linking each of these to more detailed breakdowns.
