Qualcomm reckons Android smartphone users could see 3x the wireless performance once handsets make the jump to 802.11ac WiFi, the company claims, thanks to improvements in speed, range and power consumption. That's one of the boasts around the new line-up of Qualcomm Atheros 802.11ac "gigabit wireless" devices, including the WCN3680 combination 11ac/Bluetooth 4.0/FM chipset that's intended to be used with the potent Snapdragon S4 MSM8960.
