Quantenna, has announced a new 802.11ac QSR1000 chip that is capable of delivering up to 1.7Gbps throughput. The new chip achieves the wireless throughput by supporting a combination of Multi-User MIMO, four spatial streams, 256-QAM modulation, and beamforming technology. More information on 802.11ac and the related technologies can be found here.
The Quantenna chip is a competitor to Broadcom's offerings and it is intended for use in wireless routers, access points, Set Top Boxes (STB), and other consumer electronics gear. It is the first "wave 2" (second iteration of the 802.11ac specification) 802.11ac chip, and is the fastest so far. Quantenna was able to get a theoretical max of 435.2Mbps of throughput per spatial stream, which is pretty impressive. Unfortunately, client devices (computers, smartphones, tablets, et al) will also have to support the MU-MIMO technology and have the hardware to transmit and receive multiple streams to take full advantage of the 1.7Gbps max throughput.
There is no word on which upcoming wireless devices the Quantenna chip will be used in, but the company is making the new QSR1000 chip available to manufacturers as early as Q3 of this year. Actual routers and other gear using the chip and widely available to consumers will likely not hit the market until early next year, however.
