10 Gbps Wi-Fi announced in 2015

Today, the fastest Wi-Fi routers can achieve a speed of about 1 Gbps, subject to the use of high-performance network cards. Next year, this achievement may become obsolete if Quantenna Communications releases its new Wi-Fi chipset.

Today, the majority of chipsets on the mass market provide simultaneous transmission of three spatial streams (3x3 MIMO). Routers that meet the 802.11ac standard can transmit data at speeds up to 1.3 Gbit / s at a frequency of 5 GHz. At CES, ASUS announced a new router built on Quantenna 4x4 MIMO chipset, which will be able to provide speeds of up to 1.7 Gbps. The other day, Quantenna announced that it is working on the creation of an 8x8 MIMO chipset, thanks to which the transmission speed via Wi-Fi can reach 10 Gbit / s.

The developer claims that the new chipset will be compatible with previous 802.11a / b / g / n standards. It is created on the basis of technology MU-MIMO (multi-user MIMO). The basis of the MIMO technology itself is the principle of receiving and transmitting data using multiple antennas located on one device. MU-MIMO allows you to transfer data simultaneously to multiple devices, amplifying the signal at the transmitting device. The new chipset will provide adaptive beamforming, in which the transmitter and receiver analyze the signals that are exchanged to determine the optimal signal propagation.

The solution from Quantenna will be built on the “connection” of several channels at a frequency of 5 GHz to achieve a total bandwidth of 160 MHz (modern 802.11ac routers provide a bandwidth of 80 MHz). The developer believes that their new product will be used to solve various problems, including the creation of entertainment networks and ISP-infrastructure. For example, Vivint, which provides secure access to the network, uses 4x4 chipsets in its solutions .

However, Quantenna does not plan to develop mobile versions of the 8x8 chipset, nor will there be a version for USB routers. The novelty will be used only in conventional routers, network cards, bridges and on motherboards of laptops and desktops.
