Quantenna: 802.11ac Chipset

Posted by Sam Churchill on

Quantenna, an innovator in 4×4 MIMO Wi-Fi, today announced the world’s first 802.11ac solution providing gigabit-speed Wi-Fi using their QAC2300 chipset. Using 4×4 multiple-input multiple-output (MIMO) technology, Quantenna says their chip will enable bandwidth-intensive consumer electronics applications such has home video in wireless routers, access points, and high-end consumer electronics devices.

The QAC2300 two-chip solution is the first to support the latest, fastest version of WiFi — 802.11ac. The new IEEE standard was developed to deliver Gigabit speeds and generally uses four 20 MHz channels in the 5 Ghz WiFi bands.

It’s downwardly compatible with previous WiFi standards such as 802.11n (above).

By combining its 4×4 MIMO capabilities with 802.11ac, Quantenna is pursuing whole-home video distribution with products that will deliver gigabit-wireless speeds during 2012. Quantenna will be showcasing its 802.11ac chipset at the 2012 International CES in Las Vegas, Nevada, on January 10-13, 2012.

The 802.11ac draft, also known as 802.11 VHT (Very High Throughput), uses the existing 5 GHz Wi-Fi band with wide 80 MHz or 160 MHz channels, improved modulation, and simultaneous multi-user MIMO for throughputs above 1 Gbps.

Next would come 802.11ad, which would add the unlicensed 60 GHz band to Wi-Fi. According to Ali Sadri, Director of the Intel Mobile Wireless Group and Chairman of the WiGig Alliance, WiGig has been confirmed as the baseline specification for draft 802.11ad.

The potential unification of Wi-Fi with 60 GHz in the form of 802.11ad would allow 60 GHz to build on the installed base of Wi-Fi networks. WiGig has developed profiles for wireless HDMI, DisplayPort, USB, and PCIe interfaces. WiGig supports HDCP 2.0 content protection.

According to the In-Stat report released in February 2011, 802.11ac-enabled device shipments will soar to nearly 1 billion by 2015. The 802.11ac standard expands on the broad frequency bands and multiple-antenna capabilities of 802.11n to deliver the speed and performance that consumers need from retail devices, while retaining backward-compatibility with 802.11n.
