For the past few years, Apple has been working to develop modem chips in house, and 2023 is when we could see Apple-designed chips debut. Right now, Apple is using modem chips from Qualcomm, but after a legal dispute back in 2019, Apple is eager to stop purchasing Qualcomm chips.
In November 2021, Qualcomm’s CFO said that Qualcomm expects to supply just 20 percent of Apple’s modem chips in 2023, and as Apple has no other modem chip supplier, that suggests Apple’s own modem technology is nearing launch. Apple analyst Ming-Chi Kuo has claimed that Apple’s chips could debut in the 2023 iPhone models.
We don’t know anything about Apple’s modem chips at this time, but presumably the technology will be on par with or better than the 5G chips that Qualcomm is producing if the A-series and M-series chips are any indication.
