1.General Description
PIXIE is a highly integrated single-chip 802.11n Wireless LAN (WLAN) USB
2.0 Multi-Function network interface controller with integrated
Bluetooth 2.1/3.0/4.0 controller. It combines a WLAN MAC, a 1T1R capable
WLAN baseband, and RF in s single chip. The RTL8723BU provides a complete
solution for a high-performance integrated wireless and Bluetooth device.
The integration provides better coordination between 802.11 and
Bluetooth, and with sophisticated dynamic power control and packet traffic
arbitration, RTL8723BU is able to provide the best coexistence performance
