Apple self-developed 5G baseband chip may be facing failure. As early as 2019, it has been reported that it will independently develop 5G baseband chips, and when the iPhone 15 is released, it will completely abandon the Qualcomm 5G baseband chip and adopt Apple’s own 5G baseband chip developed. But the good times did not last long. At the end of June this year, Apple’s project to develop its own baseband chips seemed to have failed. The iPhone 15 may continue to use Qualcomm’s 5G baseband chips. So why can’t Apple, which focuses on technology research and development, develop and ? What about the 5G baseband chip? And why does Apple give up all Qualcomm baseband chips? Let me analyze it for you below! There are two reasons:

5G baseband chip

1. In many people’s minds, the chips used in iPhones are A-series chips independently developed by Apple. In fact, as early as when the iPhone was first born, the chips used were Qualcomm chips, as long as you use Qualcomm chips, you will buy chips from Qualcomm. The sales of iPhones are very large, and Qualcomm chips are expensive, so Apple will need to pay a huge amount of money to Qualcomm, which will affect Apple's business. In terms of revenue, Apple has independently developed A-series chips, and has surpassed Qualcomm chips in terms of performance. The same is true for 5G baseband chips. In addition to the core chip in the mobile phone, a chip responsible for communication transmission is also needed, which is the baseband chip. Since the current mainstream communication network is the 5G network, the baseband chip of the 5G communication network is the baseband chip required by global smartphone manufacturers. At present, Qualcomm is the best maker of 5G baseband chips. In our country, Huawei also has the technology to independently develop 5G baseband chips, and has long been used in Huawei mobile phones . 5G baseband chips are expensive. Apple needs to purchase a large amount of money from Qualcomm every year to purchase 5G baseband chips. Therefore, Apple feels that it is not cost-effective, so it decided to independently develop 5G baseband chips.

2. The IOS system in Apple mobile phones seems to be somewhat incompatible with Qualcomm 5G baseband. When we use Apple mobile phones to make calls, we occasionally encounter poor picture quality or weak signals. This is incompatible with Qualcomm baseband There is a big reason for chip incompatibility. Since IOS is a closed operating system, its compatibility with Qualcomm baseband chips is not very good, so Apple decided to independently develop 5G baseband chips in 2021.

But the reality is not ideal. The research and development of baseband chips is very difficult, much more difficult than the research and development of Soc type chips such as Kirin 9000, Qualcomm Snapdragon 8, A15 and so on. The reason why Apple has used Qualcomm baseband chips for a long time is that it cannot successfully develop them. However, Apple still tried to develop a 5G baseband chip project in 2019. It plans to use self-developed 5G baseband chips in the iPhone 15 mobile phone in 2023. This way Not only can it get rid of dependence on Qualcomm, but it can also solve the iPhone's communication problems of poor call quality and weak signal. Yes, this research and development still failed. When the iPhone 15 mobile phone is released in 2023, the baseband chip equipped will still be the 5G baseband chip provided by Qualcomm.
