iPhone 7 cellular performance test: Qualcomm's modem is better than Intel's
With the iPhone 7, Apple diversified its modem supply for the first time. The company chose Intel and Qualcomm to provide baseband chipsets for two variations on the iPhone.
The Intel version supports the GSM, WCDMA, and LTE networks, and Qualcomm's supports GSM, CDMA, WCDMA, TD-SCDMA, and LTE networks. Qualcomm's modem powers the Verizon, Sprint, and SIM-unlocked iPhone 7 and 7 Plus.
If you have one of those versions, congrats! Your iPhone is capable of much better cellular reception than the Intel model, according to extensive testing from Cellular Insights.
