GlobespanVirata Unveils WLAN Chipset for 140 Mbps

GlobespanVirata unveiled a new "PRISM Nitro XM Xtreme Multimedia" solution that is claims will deliver WLAN throughput rates of up to 140 Mbps -- or 40 times faster than 802.11b -- while being compatible with all 802.11g and 802.11a/g products. The company described the technology as both standards-compliant and non-proprietary -- "a turbo solution that is not only fully compatible with existing systems and future standards, but also does not cause interference to other networks in the area."


In a typical wireless network access point (AP) configuration, throughput rates decline as more clients associate with the AP. PRISM Nitro XM reduces overhead throughput loss by creating an automatic, secure, high-speed link directly between wireless clients when they are within communication range of each other. This allows clients to communicate directly with each other at speeds of up to 140 Mbps while maintaining a simultaneous network connection with the AP. The company is targeting the technology at advanced home networking applications such as multi-channel CD-quality audio and DVD-quality video. http://www.globespanvirata.com
