3. Overview
3.1. Scope
This document describes the specifications of US305 WLAN USB
module. The low power consumption and smaller size are suitable for USB
adapter.
US305 implements half-duplex OFDM, CCK, and DSSS baseband
processing supporting relevant IEEE 802.11n data rates. The MAC
supports the IEEE 802.11 wireless MAC protocol as well as 802.11i
security, receive and transmit filtering, error recovery, quality of service
(QoS), and Extended Range technology, dramatically increasing WLAN
performance.
