Apple rumored to be moving iPhone baseband chip design in-house
While there is some speculation that Apple will design a SoC that will include AP and baseband chips, the industry sources say that the odds favor Apple continuing to use discrete baseband chips. If Apple decides to go ahead with the in-house design, the decision will have a financial impact on both Qualcomm and TSMC. The sources say that Qualcomm is the leading player in the $16 to $19 billion global baseband market, with a larger than 50% slice of the pie.
The baseband processor manages all of the radio functions on a handset, like the Apple iPhone. Any function that requires the use of an antenna will go through the processor.
