In an earlier online press conference, Apple announcedNew and warm HomePod Mini, and the first simultaneous launch of four modelsiPhone 12 series models, including iPhone 12 mini, iPhone 12, iPhone 12 Pro, and iPhone 12 Pro Max, but there are still some details that Apple did not elaborate on at the press conference.
The version that supports millimeter wave band connection specifications will only be sold in the United States first
For example, at the press conference, it was stated that the new iPhone 12 series all support mainstream 5G connection specifications, which not only correspond to the sub-6GHz frequency bands, but also to the millimeter wave frequency bands. However, because the 5G connection specifications supported by telecom operators in different regions are different, for example, currently only Verizon in the United States provides large-scale millimeter wave frequency band connection specifications (which is why Verizon CEO Hans Vestberg was invited to give a speech at the press conference). Therefore, the iPhone 12 series sold in the United States all additionally support millimeter wave connection functions, and there is also a millimeter wave antenna filling layer design on the side of the body.
The version sold in the Chinese market incorporates the 700MHz n28 and n12 frequency bands, allowing it to provide 5G network services to China Broadcasting Corporation, the fourth telecom operator in addition to China Mobile, China Connect, and China Telecom.
至於在台灣市場銷售版本則支援包含n1、n2、n3、n5、n7、n8、n12、n20、n25、n28、n38、n40、n41、n66、n77、n78、n79頻段在內的5G NR連接規格，僅支援6GHz以下頻段的5G網路連接功能，並未加入支援毫米波頻段，而4G LTE連接功能則對應4×4 MIMO與LAA技術，因此基本上都能對應五大電信業者所提供5G網路服務 (亞太電信目前將會藉由遠傳電信合作網路頻段資源提供服務)。
Added support for China's BeiDou satellite positioning system, the French version will still provide wired headphones
In addition, the new phone also officially supports the Beidou satellite positioning system used in China. In addition to the previously supported US GPS satellite positioning system, the Galileo satellite positioning system used in Europe, and the GLONASS satellite positioning system used in Russia, it also supports the QZSS quasi-zenith satellite positioning system used in Japan. The only missing satellite positioning systems are the IRNSS and NAVIC regional satellite positioning systems used in India.
As for Apple's cancellation of the provision of wired headphones and USB chargers in the iPhone 12 series, this is to make the packaging of the new phones smaller, thereby improving environmental benefits and reducing transportation losses. However, the version sold in France must provide headphone accessories in the box due to a law that came into effect in France in 2010, otherwise it will not be able to be sold on the market. Therefore, the new iPhone 12 series sold in France may be the only version that continues to provide wired headphones (but still will not provide a USB charger).
Other details not yet disclosed at the conference include the following:
● Supporting Thread technology, HomePod Mini will support connecting to IoT devices other than HomeKit
