802.11n Wireless USB Adapter

Chapter 1 Introduction
1.1 Welcome
Thank you for purchasing Zonet Z W2542-802.11n wireless USB adapter. Z W2542
connects you with I 802.11n(Draft 2.0) networks at receiving rate up to an incredible
300Mbps! By using the reflection signal, 802.11n's “Multiple In, Multiple Out” (MIMO)
technology increases the range and reduces “dead spots” in the wireless coverage area.
Unlike ordinary wireless networking of 802.11b/g standards that are confused by
wireless reflections, MIMO can actually use these reflections to increase four times
transmission range of 802.11g products. Besides, when both ends of the wireless link are
802.11n products, MIMO technology can utilize twice radio band to increase three times
transmission speed of ordinary 802.11g standard products, and can comply with
backwards 802.11b/802.11g standards.
Soft AP supported by Z W2542 can help you establish wireless LAN networking with
lowest cost. Besides, WPS (PBC and PIN) encryption method can free you from
remembering the long passwords. Complete WMM function makes your voice and video
more smooth.
