Only two iPhone12 series support millimeter wave frequency bands: they may not be available in China

According to the current speculation by various media, the new iPhone 12 series may be unveiled in mid-October, including iPhone 12 (also known as iPhone 12 mini), iPhone 12Max and iPhone 12 Pro, iPhone 12 Pro Max two versions totaling four All models support 5G networks, but the network frequency bands are not exactly the same. Now there is the latest news. Recently, a whistleblower revealed that the millimeter wave frequency band of two of these models may not be available in China.

According to the latest news released by the relevant whistleblower, only two of the four new iPhone 12 models fully support Sub-6GHz and millimeter wave bands (iPhone 12 Pro, iPhone 12 Pro Max), and the other two only support Sub- The 6GHz frequency band (iPhone 12 mini, iPhone 12Max) does not support millimeter waves. So what is the difference between these two frequency bands?

According to reports, Sub-6GHz and millimeter wave are the two frequency band codes of 5G networks. At present, my country mainly uses Sub-6GHz. This frequency band is characterized by strong signal penetration, but the data transmission speed is slower than millimeter waves. The US mainly uses the millimeter wave frequency band, which is characterized by high transmission speed but poor penetration. There is no doubt that the models that support both Sub-6GHz and millimeter wave frequency bands are naturally the best. However, relevant industry insiders also said that the current 5G network speed of my country's Sub-6GHz band is already very fast, but the iPhone signal has always been a much criticized problem, so it is a better way to choose the stronger Sub-6GHz signal. Good choice.

In other respects, according to previously exposed news, the new iPhone 12 series will continue the full screen design of the notch, and use a flat middle frame similar to the iPhone 4. The two Pro versions will have 10-bit color depth and 120Hz refresh rate. It will be equipped with an A14 processor based on a 5nm process to support 5G networks. In addition, this series of new phones will continue the square camera module of the previous one. Among them, two iPhone 12 series are equipped with rear dual cameras, while the two iPhone 12 Pro series will be equipped with rear three cameras, and only iPhone 12 Pro Max It will be equipped with LiDAR sensors.

It is reported that the brand-new iPhone 12 series is expected to be officially released on October 13th, US time, with a price starting at US$649. We will wait and see for more detailed information.
