The majority of countries that are busy in 5G rollout have stuck with the sub-6GHz standard due to easier deployment and higher reliability compared to mmWave networks due to its longer range. However, mmWave 5G continues to dominate in sheer speed, and Apple likely wants more adoption of the standard in various regions. This is why, according to a new report, around 60 percent of iPhone 13 shipments will include mmWave 5G antennas.

According to DigiTimes, Apple has enlisted AT&S as a new supplier for BT-based antenna-in-package substrates for the new iPhone 13 series, with the total tally of suppliers now standing at five. The addition of a supplier is expected to increase Apple’s output of mmWave 5G-ready iPhone 13 models, with the report stating that estimated shipments of such models could reach 90 million for 2021.
