Apple has decided to stop developing its own 5G modem chip after several failed attempts to perfect it, according to unconfirmed sources in South Korea.
According to the operator of news aggregator "yeux1122" on the Naver blog, a South Korean web portal, supply chain sources associated with Apple's 5G modem division have revealed that the company's attempts to develop its own modem have so far failed, and that Apple is ending an investment program that has lasted for years. Apple is ending the multi-year investment program. Separately, tipster @Tech_Reve also said he heard similar news from supply chain sources in Japan. It's important to note that there's no way to know for sure if the report is true, but according to a September report from The Wall Street Journal, Apple's plan to develop its own modem chips has run into a number of difficulties, including unrealistic goals, a lack of sufficient understanding of the challenges involved, and unusable prototypes. Earlier this month, Bloomberg's Mark Gurman also reported that Apple is having trouble trying to develop a 5G modem to replace the one Qualcomm uses in its iPhone and other products. Development of Apple's own modem chip is reportedly in the early stages and "could lag behind competitors by years". One version in development doesn't support the faster millimeter wave technology, and Apple has run into problems with Intel's code. The code needs to be rewritten and can cause existing features to malfunction when new ones are added, and Apple also had to be careful not to infringe on Qualcomm's patents when developing the chip.
