Start-up amplifies Wi-Fi coverage
Published: 18 Aug 2003 10:00 BST
Airgo Networks is expected to announce on Monday that its multiple antenna wireless networking technology and its first chip, which will use the technology, are being tested now with potential customers.
The company's technology extends the range and increases the throughput of wireless networks, according to the company, which could potentially mean simpler and less expensive installations of networks while improving performance. But as with all start-ups and new technologies, the proof will be in the finished product.
Volumes of those chips -- the AGN100 -- are expected to increase in the coming months with products, such as notebooks, using the chips, said Greg Raleigh, chief executive of the start-up.
Airgo is already in discussions with original equipment manufacturers looking to use the start-up's chips, including major notebook makers, and with quality of service protocols and the improved range and performance of networks using the chips, the company is "in the middle of the multimedia home vortex" that consumer electronics and PC companies have been touting for the last couple years, according to Raleigh.
Companies such as Hewlett-Packard, Intel and Sony have been basing their consumer strategies on the idea that wireless networks will be installed in homes, allowing individuals to share resources, such as broadband connections and printers, as well as content on devices connected to the network.
Airgo has raised $52m (£32m) in funding from firms such as OVP Venture Funds, Sevin Rosen Funds, Nokia Venture Partners and Accel.
Typically, multiple wireless signals in a network can be detrimental because they can interfere with one another. The future of wireless technology is multiple input and multiple output (MIMO) technology, which takes advantage of multiple signals, said Craig Mathias, an analyst with research firm Farpoint Group.
"The only other way to get more information into a signal is to cram more bits into the signal, but the more bits you cram, the less range you get," Mathias said. "What's being done is that multiple signals are being sent out and received and a more reliable signal is being created in the end."
Airgo's new chip supports the 802.11a, b and g standards and can achieve transfer rates of up to 108 mbps. The chip also supports draft versions of the 802.11i and 802.11e specifications.
