5G: The fifth generation mobile communication technology is the latest generation of cellular mobile communication technology, and it is also an extension after 4G(LTE-A, WiMax), 3G(UMTS, LTE) and 2G(GSM) systems.
The performance goals of 5G are high data rate, low latency, energy saving, low cost, high system capacity and large-scale equipment connection. The first phase of the 5G specification in Release- 15 is to adapt to the early commercial deployment.
The second phase of Release- 16 will be completed in April 2020 and submitted to the International Telecommunication Union (ITU) as a candidate for IMT-2020 technology. ITU IMT-2020 requires a speed of up to 20 Gbit/s, which can realize wide channel bandwidth and large capacity MIMO.
20 19 10 3 1, the three major operators announced the 5G commercial package, and officially launched the 5G commercial package on 1 1.
Reasons for not supporting: Apple A series processors have never integrated baseband chips, and all communication baseband modules are plug-ins. Therefore, this A 12 processor maintains the previous "tradition", which can be regarded as an attitude of Apple towards hardware.

At the recent World Mobile Communications Conference (MWC), 5G became the focus of attention. Samsung, Huawei, Xiaomi, OPPO, vivo, Yijia and many other companies have demonstrated their respective 5G mobile phones, and these products will be listed in the second half of this year.
Apple did not participate in MWC as in previous years, but its "sense of absence" has become more and more prominent this year, because so far Apple has not announced the business plan of 5G mobile phones. At the subsequent Apple shareholders' meeting held on March 1 day, Apple CEO Cook did not mention any information related to 5G.
As the second largest mobile phone manufacturer in the world, there are many reasons for Apple's "absence" on 5G mobile phones.
At present, except Huawei, almost all companies that have announced the launch of 5G mobile phones have adopted Qualcomm's 5G chips. However, due to the protracted patent dispute with Qualcomm, Apple had to switch to Intel's technical solution, which also led to the widespread belief that "Apple will not be able to launch the 5G terminal before 2020".
Some insiders also pointed out that Apple's delay in announcing the launch of 5G mobile phones has its own considerations. At present, 5G technology still faces the problems of antenna debugging difficulties, high power consumption and high heat generation. For the iPhone, which has been criticized for its poor signal and short battery life, it is really difficult for Apple to cite 5G technology before finding an ideal solution.
In the past two years, Apple has been regarded by the outside world as lacking in innovation, overpriced and its sales volume has gradually declined. Before launching its own 5G mobile phone, price reduction became an effective means for Apple to counter its competitors and maintain product sales.
