An iPhone with 4G connectivity? It's more likely than you think.
We can now confirm that the Qualcomm MDM9615M is the 4G LTE modem powering this new feature.
After being teased for over a year by Android bullies, the iPhone faithful finally have 4G LTE on their side. What will they do with this newfound power? Only time will tell.
The Qualcomm MDM9615M is a 28 nm LTE (FDD and TDD), HSPA+, EV-DO Rev B, TD-SCDMA modem.
The MDM9615 allows for multi-spectrums, multi-mode LTE support. It is responsible for transmitting simultaneous voice and data transfer on LTE (provided the carrier has the infrastructure to allow simultaneous voice and data transfer.)
We also find the Qualcomm RTR8600 multi-band/mode RF transceiver. The RTR8600 is paired alongside the MDM9615 to support various bands, including 5 UMTS bands, and over 5 LTE and 4 EDGE bands.
