Such LTE Advanced Pro speeds are present in only a handful of countries for now, like South Korea (oh, the irony!), Australia or Sweden, but when carriers here are ready with such rollout, Qualcomm will have the modem to match. Verizon has a pilot 1Gbps network a its HQ already, and, needless to say, says that such fiber-like speeds are meant for the next generation of video streaming.
For now, suffice it to say that the modem supports Cat. 16 LTE speeds, while others are up to Cat. 10, and is built on the trendy 14nm process, meaning a much smaller footprint and power consumption than before, despite doubling the speed over previous generations. The other interesting tidbit about Qualcomm's X16 LTE radio is that it is created with a new modular architecture that will allow quick scaling and adaptation to various tasks, scenarios and IoT gadgets that will need LTE connectivity.
The first units are shipping to customers for sampling as we speak, and will be available in retail devices in the second half of the year. Given that Apple always try to keep the iPhone at the forefront of LTE connectivity - the iPhone 6s supports a record number of bands - we wouldn't be surprised if Qualcomm's new fast and efficient modem makes it into the iPhone 7 and Apple A10. As for Qualcomm's own chipsets? We doubt this modem will see the light of day before Snapdragon 830 goes into devices next year.
