The patent is related to radiofrequency systems used for wireless communication of data between devices and/or with a network, and mainly revolves around the 5G NR mmWave and sub-6 GHz wireless technology.
These radio frequency systems emit wireless signals to help with data transfer. Sometimes, the signals may be absorbed by someone in close proximity to the device.
The rate at which these signals may be absorbed by the human body is regulated by a Maximum Permissible Exposure (MPE) limit for 5G NR mmWave systems, and by a Specific Absorption Rate (SAR) set for sub-6 GHz systems.
To ensure compliance with MPE and SAR, devices often output lower than maximum output energy when they detect someone is around. That’s where the problem arises, as many radiofrequency systems are not capable of detecting the presence of a human body nearby. As a result, some devices output lower than maximum output power at all times. This leads to a degradation in the speed of wireless communication.
Apple has come up with a multi-dimensional architecture to make sure devices operate optimally at all times without putting the user at risk.
Will the iPhone 12 employ this architecture?
At the same time, a supply chain report claims that mass production will not begin until November for the models that will support the sub-6GHz frequency band.
Taiwanese sources also claim that the 5.4-inch iPhone 12, which will reportedly be called the iPhone 12 mini, and the 6.1-inch model that supports sub-6GHz will be the main sales drivers. Now, this bit is interesting, and it suggests that both higher end models will support the fastest 5G speeds.
