Quantenna is working on a 10-gigabit Wi-Fi chipset that will utilize eight data streams simultaneously.


Quantenna is working on a new Wi-Fi chipset that will increase throughput by a factor of ten.

While current-gen Wi-Fi ac routers can simultaneously receive three data streams through a 3×3 MIMO chipset, with Asus’ upcoming RT-AC87U router utilizing Quantenna’s QSR1000 4×4 MIMO chipset to deliver 1.7Gbps throughput, Quantenna has stated that its 10-gigabit offering will use 8×8 MIMO streams.MIMO (multiple input/multiple output) is a technology through which several data streams can be sent by using multiple antennas on a single transmitter and receiver. Quantenna will use a MU-MIMO technology (multi-user MIMO) technology that can transmit to a number of devices at once.

Quantenna’s chipset would utilize the 802.11ac Wi-Fi standard in addition to the 802.11a/b/g and n standards. The chipset will use 8×8 MIMO streams to deliver an overall bandwidth of 10-gigabit. To do so, Quantenna is using a technique called channel bonding in which several channels on the 5GHz frequency band are merged together to form a single channel that can deliver 160 MHz of bandwidth. Current Wi-Fi ac routers utilize channel bonding to deliver 80 MHz of bandwidth.

While MIMO offerings are starting to emerge in smartphones (the Galaxy S5 has a MIMO modem), Quantenna announced that its 10-gigabit chipset would not be available on battery powered devices. The 10-gigabit card would be on routers, PCIe cards, bridges, and notebook and desktop motherboards. Commercial devices that feature this chipset will launch in 2015.
