Chip giant Intel (NASDAQ: INTC) entered the cellular modem business in 2011 with the acquisition of Infineon's wireless division. Since then, Intel has poured a lot of resources into that business with the aim of transforming it from a technology laggard into a leader.This business scored its first big win under Intel's wing in the second half of 2016, when Apple (NASDAQ: AAPL) chose to use Intel's XMM 7360 LTE modem to provide the cellular capabilities for a portion of its iPhone 7-series devices.
