D-Link said today it has started shipping its DGL-4500 Draft 802.11n Xtreme N Gaming Router.
The router combines a single dual-band Draft 2.0 802.11n radio based on Atheros XSPAN technology with D-Link's "GameFuel" technology—D-Link's branding of Ubicom's "StreamEngine" auto-QoS technology.
Linksys today announced the first of its Ultra RangePlus wireless networking products.
The Ultra RangePlus Dual-Band Wireless-N Gigabit Router (WRT600N) and Dual-Band Wireless-N Notebook Adapter (WPC600N) are 802.11n Draft 2.0 Wi-Fi Certified and operate in the 2.4 GHz and 5 GHz Wi-Fi bands. The WRT600N has two radios for simultaneous dual-band coverage. Both products are based on Broadcom Intensi-Fi draft 11n chipsets.
SmallNetBuilder has discovered a hole in the Wi-Fi Alliance's 802.11n Draft 2.0 test suite that can allow Wi-Fi Certified products to interfere with existing wireless networks, in direct violation of a mandatory Certification requirement.
A long-running battle in the standard has been whether to allow the use of "wide-channel" operation in the 2.4 GHz band that is used by the majority of Wi-Fi products. The mode, also referred to as "channel bonded" or "40 MHz bandwidth" mode, uses up two of the available three non-overlapping channels in the band, making it impossible to avoid interfering with other wireless networks operating in the center of the band.
Interference from draft 802.11n channel-bonded networks can, at worst, render 802.11b and g wireless networks inoperable and, at minimum, cause slowdowns and unreliable connections.
Broadcom today announced what it says is the world's first full-featured, single-chip 802.11n solution.
The Broadcom BCM4322 combines all of the elements of a wireless LAN subsystem onto a single silicon die, including 802.11 MAC, baseband processor, 2.4 GHz and 5 GHz radios and other WLAN components. Broadcom claims that the device can deliver " over 200 Mbps of actual wireless throughput".
