Quantenna debuts chips for next-gen Wi-Fi

Fabless semiconductor designer Quantenna Communications is now sampling a set of integrated chipsets for the next generation of Wi-Fi – 802.11n.

Current Wi-Fi implementations – 802.11b and g – sometimes fail to penetrate all corners of the buildings in which they’re installed, and are sometimes prone to interference. The new 802.11n uses beam-forming techniques to overcome that issue, and cranks up the speed of Wi-Fi up to 1 Gbps, all to support reliable Quantenna QHS Plugwireless distribution of HD multimedia content.

TV providers continue to search for a reliable means of distributing HD video and other media throughout their customers’ entire homes. The 802.11n version of Wi-Fi might be part of the solution – it might be the whole solution.

The members of the Quantenna High Speed (QHS) family of chipsets overcome interference and dead zones, enabling consumers and carriers to reliably deploy wireless HD, HDTV and IPTV services, to any point in the home over a plug-and-play wireless network.

The company claims its chipsets are the first in the industry to bring together the following technologies in a standards-compliant 802.11n solution: 4x4 MIMO radio/transceiver; Tx beamforming (which enables the chip to locate receiving devices and focus the signal on them); concurrent dual band mode (which supports real-time video transmission via the 5 GHz band and data over the 2.4 GHz band; Vector Mesh Networking (adaptive vector mesh routing); and the integration of high efficiency power amplifiers (PAs) with 18 dBm output power along with low-noise amplifier (LNA), video graphics array (VGA), switches, baluns and diplexers that constitute a front-end module.

The QHS family consists of three members:

  • 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.

The company said it will be 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.
