iPhone 6 Will Have Really Fast Wi-Fi That Makes Phone Calls, Too
The iPhone 6 will include 802.11ac Wi-Fi, with speeds of 433 megabits-per-second (Mbps). To translate that is at least 3 times faster than the current Wi-Fi speeds.
But wait, there's something even better: The phone will allow you to make phone calls over Wi-Fi, too. So if you are someplace where the cell signal is awful but the Wi-Fi is strong, the phone will switch you to the Wi-Fi network and make the call that way, at least with carriers like T-Mobile that support that feature.
But before you get too excited, T-Mobile's Android users want you to know that they've had Wi-Fi calling for a while now.
We're still waiting on word if Verizon and AT&T will be supporting that feature.
