With the new iPhone being unveiled, we're finding out the detailed technical side of things - with one of the big improvements being on the networking side of the iPhone 6. Apple has provided LTE 150Mbps, and Wi-Fi 802.11ac, which should keep fast users very happy.
The iPhone 6 now supports up to 20 LTE bands (which is more than any other smartphone) and LTE roaming. The iPhone 6 also does "carrier aggregation" which ensures the maximum speed on your bigger iPhone. The new iPhone also supports VoLTE, or Voice over LTE. Wi-Fi calling is also a thing with the iPhone 6, but it is limited to just two providers: T-Mobile in the US, and EE in the UK.
