- Headline figures: 650 Mbps Wi-Fi data throughput, an 867 Mbps PHY rate on an 80MHz channel, 50 percent better coexistence with Bluetooth, and indoor location accuracy down to one meter[1][2]
- Other features listed: transmit beamforming, "which pinpoints a device's location within a network to provide better throughput to that location", LDPC, TurboQAM for the highest 2.4 GHz data rate, RTT-based indoor location, an integrated PA, LNA and TR switch, a low power PCIe host interface for WLAN with UART for Bluetooth, and the first Angle-of-Arrival direction finding on a smartphone; it supports Android, Windows and Chrome[1][2]
