  • Description

    This adapter operates under 2.4GHz and 5Ghz. LM845 is compliant to IEEE 802.11ac /a/b/g/n and Bluetooth® v4.2, with backward compatibility with Bluetooth® v2.1+EDR, and v3.0. Bluetooth® Low Energy (LE) can operate simultaneously. Classic and LE can operate simultaneously.

    The Realtek IC uses a USB main interface and offers high throughput for both WiFi and Bluetooth® connections, connected via a (HCI) USB 2.0 TYPE A interface. The LM845 provides a complete solution for a high-performance wireless client, it also supports WiFi Direct that can easily be used to build a WiFi P2P PAN network.

    Bluetooth® includes EDR transmission and supports bandwidths up to 2Mbps, or in HS Mode up to 3Mbps.
