Apple is very likely to design and build baseband chips for future iOS devices. That probably won’t start until next year, however, according to AppleInsider.

In a note to investors, JP Morgan analyst Rod Hall says Apple-designed chips won’t happen until 2015 because they are “notoriously difficult” to develop and produce.

According to the report:

Apple’s choice to produce its own wireless modems would likely be motivated in part by a desire for increased power efficiency, Hall believes. Apple’s current logic board designs utilize a baseband chip that is separate from the company’s A-series application processors, and the company may be looking for ways to integrate the two chips into a single package.

On Tuesday, DigiTimes said that Apple was planning on forming a research and development (R&D) team to develop iPhone baseband chips in-house.

Baseband chips used in Apple’s current-generation iPhones are purchased from Qualcomm and mass-produced at Taiwan Semiconductor Manufacturing Company (TSMC).
