1.1 Overview of the product

Comply with 802.11n Standards

The IEEE 802.11n Wireless USB adapter provides users to launch IEEE 802.11n wireless network

in the 2.4 GHz band, which is also compatible with IEEE 802.11b/g wireless devices.

Reliable Coverage

The adapter has internal intelligent antennas providing even better wireless performance,

transmission rates, stability and coverage. It includes a convenient utility for scanning available

networks and saving preferred networks that users usually connected with. Your wireless

communications are protected by up to 128-bit encryption, so your data stays secure.

Easy Installation and Connection

In addition, installation and use are further simplified by living up to USB's Plug and Play installation

approach to connecting computer peripherals. You will not need to open the case of your computer,
