Even today we comment that the "IPhone 12", according to the analyst Ming-Chi Kuo, does not have support for 22 MIMO uplink which in practice would mean higher upload speeds. Now, the Fast Company came with exclusive news related to the subject: according to the magazine, antenna of the 5G handsets released in 2020 (ie, all ?iPhone 12? models) will be made by Apple itself.
According to the article, Ma does not want to use the antenna module QTM 525, from Qualcomm, as it does not fit in the design she created for the phone. Qualcomm supply the 5G modem chip, the Snapdragon X55, which is also used in Samsung's new releases (Galaxy S20, S20 + and S20 Ultra).
Even if that is the plan, the Fast Company He also said that the company has a security plan for an iPhone prototype that uses both the 5G antenna and Qualcomm's 5G modem. This prototype would have a greater thickness and, therefore, will only be used if "Plan A" is really down the drain.
To give you an idea, Qualcomm claims that its QTM 525 antenna module supports 5G smartphone designs less than 8 millimeters thick, which gives us an idea of ??what Apple is planning for the ?iPhone 12?.
The problem is the challenges linked to this. Apple does not have a positive track record when designing its own antennas (everyone here should remember the #antennagate). In addition, 5G technology alone has its challenges, which makes things even more difficult for Ma.
Want an example? The iPhone 5G use an antenna phased array, with two parts that work together to form a radio signal beam. The beam can be directed electronically in different directions, without the antenna moving. The modem chip and the antenna module work together to make this work correctly, according to a magazine source. And having these two parts made by different companies may not be a good deal, increasing the level of complexity of the project.
As much as Apple's relationship with Qualcomm is now much calmer, Ma wants to have as few parts as possible from the supplier on the iPhone. Also according to the source of the Fast Company, the company still thinks it's paying royalties too much for Qualcomm then, the fewer components of it, the better.
For the time being, only time will tell if we will even have an antenna designed by Apple on the ?iPhone 12? the decision needs to be taken, at the most, until the middle of the year, when the mass production of the devices should start for real.
