From 'signal gate” to technological autonomy: Apple builds iPhone with stronger signal

According to news on September 7, Apple plans to introduce its own modem chips developed in 2025 to improve the signal quality of iPhones and end its long-term dependence on suppliers such as Qualcomm.

Over the years, one of the issues that has attracted much attention with Apple mobile phones is the instability of signal quality, but now this situation is about to improve. According to well-known analyst Ming-Chi Kuo, Apple plans to use its own 5G baseband chips in iPhone models after 2025. However, the first attempt at this move may be on the iPhone It will be carried out on the new SE model. After testing and verification, it will be gradually applied to the original iPhone products.

In order to realize its own 5G baseband chip, Apple has been conducting secret preparations for more than five years, and even acquired most of Intel’s smartphone modem business in 2019 , to accelerate the process of independent research and development.

Regarding the performance difference between this new baseband chip and Qualcomm modem, it is unclear whether it will directly lead to a better user experience. However, this will reduce Apple's reliance on companies such as Qualcomm in the supply chain. At the same time, there is news that the new baseband chip may significantly improve the signal quality of iPhones.

It is worth mentioning that Apple has been using Qualcomm’s baseband chips since the iPhone 5, but since the 2016 iPhone After the release of 7, due to Intel's limitations in baseband technology, Apple began to use a mixture of dual-model version basebands from Qualcomm and Intel. This change caused some signaling problems and also triggered the so-called "signalgate" incident.

In addition, Apple has been involved in patent disputes with Qualcomm, accusing Qualcomm of excessive standard necessity patent licensing fees, thereby seeking to get rid of its dependence on Qualcomm. The dispute was settled in 2019, but Apple has apparently begun to develop its own baseband chips to ensure that future iPhones can perform better in terms of signal quality.
