iPhone 13 series since the release of the sale has brought a great surprise to domestic users, and in the past, the amount of increase is not increased, even if compared with the iPhone 12 ProMax system and performance is not much different, but in general, it is still very fragrant for domestic users.
Before the release of the iPhone 13, there was a lot of news that the iPhone 13 series models would support mmWave 5G (millimeter wave 5G) in more countries and regions, but after the release, it was still limited to the US version of the iPhone 13.

Let's take a look at what millimeter wave is. First of all, the 5G network band is basically divided into sub-6GHz and millimeter wave two frequency bands, China's current development of 5G networks are basically using the sub-6GHz band, and the United States promotes the millimeter wave band 5G network.

According to studies, the millimeter wave band and sub-6GHz band have faster propagation speed and lower latency.
Millimeter waves are electromagnetic waves with wavelengths in the millimeter range, usually referring to the frequency band of 30-300 GHz, and often also include bands above 24 GHz. According to data released by HiSilicon, the Balong 5000 baseband chip is below Sub-6GHz, with a download rate of 4.6Gbps and an uplink rate of 2.5Gbps, but under millimeter wave, the download rate can reach 6.5Gbps, and the upstream rate also reaches 3.5Gbps.
Millimeter wave occupies an absolute advantage in speed, suitable for bustling large cities, especially most commercial areas in the United States, but the result of its dominant speed is that its wavelength is short, and the distance of signal transmission is particularly close. You're blocking my 5G signal" stem is why. Therefore, the Sub-6GHz band is more suitable for suburban and rural areas, and the Sub-6GHz band is more common in areas outside the United States that have covered 5G signals.
Whether it is Sub-6GHz or millimeter wave, in fact, there is no distinction between advantages and disadvantages, but the order of development is different, one is wide, one is fast, and the two form a complementary state. The experience of the full version of the 5G signal can only be achieved after complementing each other.
