Commack, NY -- In the lead-up to the 2010 Consumer Electronics Show,
where all the competing factions vying to be the multimedia wireless
distribution scheme of choice for the home will be out en masse,
Quantenna Communications Inc. has debuted a complete reference design
based on its QHS600 IEEE 802.11n wireless LAN (WLAN) 4x4 multiple input,
multiple output (MIMO) chipset.
The QHS600 was
announced (see EE
Times story in October 2008 and is a single-chip, 5-GHz solution
capable of 600-Mbit/s connections that integrates baseband, media access
control (MAC) and four RF transceivers, along with their respective
power amplifiers, low-noise amplifiers and Tx/Rx switches.
However, according to David French, CEO of Quantenna, "Of more value is
the digital beamforming hardware with on-chip DSP doing real-time
characterization of the Wi-Fi channel to perform [signal] steering on a
packet-by-packet basis." The DSP is an ARC 4 and in all there are 14
patents around this area, he added. Other features include concurrent
dual-band mode and mesh networking. According to French, it should be
under $10 by the end of 2010.
The newly announced reference design kit (RDK), dubbed the QHS600x,
consists of a radio GMII module connected via a mPCI connector to a
host adapter board and enables straightforward board boot, bring up and
program execution. It also includes integrated functions for various I/O
interfaces, including gigabit Ethernet, DDR SDRAM, flash, USB 2.0 OTG,
ARM JTAG debug port, GPIOs, serial port and four antenna ports.
Also included is a complete software developer's kit (SDK) that
implements the entire networking and device discovery/connectivity
functionality required for a wireless video bridge module supporting the
802.11n standard. Additionally, Quantenna and LitePoint have worked
together to provide a full test suite of specialized video-over-wireless
radio frequency (RF) calibration and performance-characterization
According to French, Quantenna will introduce a video bridge at CES and
he sees as strong play for its technology with service providers. The
company already has a deal
with Swisscom, one of its backers, as well as eight other
providers, unnamed as yet.
Pricing and availability
The RDK is available now, with pricing set at between $2,000 and $4,000,
depending on volume.
