Overview

The ORiNOCO 802.11a/b/g/n USB Adapter is the next generation Wireless USB Adapter capable of supporting
®
802.11n draft 2.0 in 2.4 GHz and 5 GHz bands. It provides high-speed (300 Mbps) wireless Internet access and
networking for a USB-enabled desktop anywhere, anytime. The USB Adapter is a Plug-and-Play device that connects to
and draws power from a computer's USB port.
This ORiNOCO 802.11n Wireless USB Client Adapter is compatible with a USB 2.0 slot from any manufacturer. As a
®
Plug-and-Play device, Windows XP/Vista automatically detects the wireless USB Client Adapter and initiates the
installation process. Upon successful installation, the wireless USB Adapter communicates seamlessly with other IEEE
802.11n wireless products as well as legacy products. The ORiNOCO
devices to form a stand-alone wireless Peer-to-Peer Group or used in conjunction with an Access Point infrastructure to
provide mobile clients with wireless access.

The IEEE 802.11 Specifications

In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices
operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct
sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11a/g
standard operate at a data rate from 6Mbps to 54Mbps.
IEEE 802.11n draft 2.0 improves upon the previous 802.11 standards such as 802.11a and 802.11g, with a significant
increase in the maximum raw (PHY) data rate from 54 Mbit/s to a maximum of 600 Mbit/s. IEEE 802.11n builds on
previous 802.11 standards by adding multiple-input multiple-output (MIMO) and Channel-bonding/40 MHz operation to
the physical (PHY) layer, and frame aggregation to the MAC layer.
