The first gigabit Wi-Fi chip for consumer devices is here

Quantenna, a startup building chips for sending massive data over Wi-Fi, has built the first gigabit chip for Wi-Fi networks and devices. Quantenna, which first got started delivering chips to boost in-home Wi-Fi to meet the demands of high-bandwidth applications, said Tuesday that its latest chip is available now for select customers for use in routers, home gateways and even consumer gadgets. Products containing the chips could hit the market in 2012.
The chips use a combination of four antennas on sending and receiving radios to deliver gigabit speeds under the planned 802.11ac standard. By using 4×4 MIMO and an ability to cover both the 2.4 GHz and the 5 GHz Wi-Fi frequencies,¬†Quantenna says it can deliver 2 Gbps, which is awesomely fast, but pretty useless for most homes and devices today considering our home broadband speeds are much slower.
While some places are farther along in deploying gigabit networks (shout out to The Netherlands, Sweden, South Korea and Chattanooga, Tenn.), most consumers won’t see gigabit speeds in their homes for years, if ever. So is this product necessary? Not yet, but I hope it will be. We are adding more devices to the home connected via Wi-Fi, so a more robust network is always welcome.
