It is reported that Apple has abandoned its own research and development of 5G modem chip.

CTOnews.com, Nov. 29, according to unconfirmed sources from South Korea, Apple decided to stop developing its 5G modem chip after several failed attempts to improve it.

According to the operator of the news aggregation account "yeux1122" on the South Korean portal Naver blog, supply chain sources related to Apple's 5G modem division have revealed that the company's attempts to develop its own modems have so far been unsuccessful, and Apple is ending the multi-year investment project. In addition, whistleblower @ Tech_Reve also said he heard similar news from Japanese supply chain sources.

CTOnews.com needs to point out that it is not clear whether the report is true, but according to a September report in the Wall Street Journal, Apple's plan to develop its own modem chip has encountered a number of difficulties, including unrealistic goals, lack of understanding of the challenges involved, and unusable prototypes.

Earlier this month, Bloomberg's Mark German also reported that Apple was having trouble developing 5G modems to replace 5G modems used by Qualcomm in iPhone and other products. It is reported that the development of Apple's own modem chip is at an early stage and "may be several years behind its competitors." One version under development does not support faster millimeter wave technology, and Apple is having trouble using Intel's code. The code needs to be rewritten, and when new features are added, existing functions fail, and Apple must be careful not to infringe Qualcomm patents when developing chips.
