One of the features expected to finally arrive on the iPhone with the smartphone's next iteration is LTE connectivity. According to DigiTimes, production of the needed radios is to begin in the very near future. Qualcomm is the manufacturer burdened with the task, the source clarifies. The LTE radios will be made at the TSMC factory using 28-nanometer process, and about 10,000 12-inch wafers will be required.
All in all, 28-nanometer chips are likely to be in low supply until TSMC manages to ramp up its production to 50,000 per month, which is expected to happen before the year's end. It is said that over $8 million have been invested in order to make that possible.
