Hot on the heals of several announcements coming out of the Broadsoft Connections conference, Grandstream today has announced the upcoming availability of an 802.11n/b/g Wireless USB dongle for the Grandstream GXV3140.

The new WiFi USB adapter fully complies with the latest 802.11n standard as well as legacy 802.11b/g standard. It supports low power management, and various security standards such as WEP 64/128, WPA (PSK), WPA2 (PSK), TKIP, and AES.

The wireless adapter can be plugged into the GXV3140 via the USB port located on the right hand side of the phone for connection speeds of over 150Mbps (though that’s an awful lot of video call!).

“We believe that the wireless USB adapter builds greater flexibility and portability to the GXV3140. Now users don’t have to worry about location or wiring restriction of an Internet connection to enjoy the rich features of the device.”, said David Li, CEO of Grandstream Networks.

The Grandstream GXV3140 Wireless USB Adapter is available for pre-order now from Telephonyware, with initial stock expected in November, 2009.

Update: The Grandstream GXV3140 Wireless USB Adapter is now in stock and shipping.
