Wireless 802.11 b/g/n and BT4.0 USB Module
802.11 b/g/n with Bluetooth 4.0 Combo 1T1R, miniPCIe Type, USB Module

Introduction of Products

Bointec DUB802R is a solder down module of Wireless 802.11bgn with Bluetooth 2.1/3.0/4.0 multi-function network interface controller by USB 2.0.
    It combines a wireless LAN MAC, a 1T1R capable baseband, and RF. Using by Realtek RTL8723BU, it 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, it is able to provide the best coexistence performance overview.
