MIMO 4×4 On a Chip

Posted by Sam Churchill on

Quantenna, a Silicon Valley startup announced the world’s first fully integrated 802.11n chipsets with 4×4 MIMO and transmit (Tx) beamforming. It’s designed to deliver guaranteed wireless bandwidth within homes.

Quantenna says they uniquely combine a 4×4 radio transceiver/antenna, concurrent dual band mode, mesh networking and transmit (Tx) beamforming – in a single chipset.

“Our unique combination of cutting-edge 4×4 MIMO and Tx beamforming position Quantenna in the forefront of the highly competitive Wi-Fi chip market,” said Dr. Behrooz Rezvani, Quantenna’s founder and CEO. It supports real-time video transmission via the 5 Ghz band and data over the 2.4 Ghz band. Adaptive vector mesh routing; and high efficiency power amplifiers with 18 dBm output power along with low-noise amplifier (LNA), constitute a front-end module.

They are developing a line of next-generation chipsets:

  • QHS1000 – up to 1 Gbps link speed and 600 Mbps data throughput.
  • QHS600 – up to 600 Mbps link speed and 400 Mbps data throughput.
  • QHS450 – up to 450 Mbps link speed and 200 Mbps data throughput.

It will begin sampling its QHS family of chipsets with top-tier customers in both the retail and carrier markets in Q4 2008. Pricing is available upon request.

Three wireless systems for connecting HDTVs are competing for the home, says EE Times. This “battle of technologies” is being fought between three contending systems, 5 GHz, 60 GHz, and ultra wideband (UWB), according to ABI Research. Most established wireless vendors are waiting to see how the market evolves, says the research firm.

There is no consensus among consumer manufacturers on a single standard or unified wireless HD format.

But wireless connections are expected to simplify A/V installations and allow more flexibility in positioning TVs.
