Qualcomm will still supply all the modem chips needed for the upcoming iPhone, but Apple is mulling multiple suppliers of modem chips for its 2017 series, industry sources have claimed.

Qualcomm is partnering with TSMC to supply 100% of the modem chips for use in the new iPhones slated for launch in September 2015, the sources said. The chips are built using TSMC's 20nm process, the sources noted.

The sources believe that Intel is unlikely to obtain modem chip orders for the upcoming iPhones. However, Intel could win orders for the 2017 iPhone models as Apple is searching for additional modem chip suppliers apart from Qualcomm, the sources noted.

Intel's modem chips are also built by TSMC, using the foundry's 28nm process technology, the sources added.

Various media outlets have quoted a Northland Capital Markets analyst as saying that Intel had won part of the modem business in the next-generation iPhones scheduled tfor launch in September.
