Quantenna chips wirelessly deliver HD
video to multiple TVs in home
Quantenna Communications, Inc. has announced a family
of carrier-grade 4x4 multiple input multiple output (MIMO)
Wi-Fi home-networking chipsets, which are said to deliver
up to four simultaneous spatial streams with wire-like quality.
Quantenna's QHS7xx family of Full-11n chipsets delivers
up to 600 Mbps of bandwidth making them suitable for delivering
IPTV and other Internet-based video streaming and data distribution
services over an ultra-reliable, high-performance Wi-Fi
connection.
Quantenna new QHS7xx family enables gateways, routers,
video bridges and other products to transmit concurrent
multiple 1080p-resolution high-definition (HD) video streams
and standard-definition (SD) streams to multiple televisions,
with whole-home coverage, over a single wireless home network.
The family enables home networks to deliver the full range
of services and applications - including multi-room digital
video recording (DVR) and video streaming services - without
requiring users to run cabling through the residence, and
with a seamless and secure self-installation process.
"Quantenna is enabling the wireless video revolution
by giving users a single solution both for standard data
networking and for whole-home, carrier-quality HD video
streaming and distribution," said Dr. Sam Heidari,
Interim Chief Executive Officer and Vice President of Research
and Development for Quantenna. "Our QHS7xx chipset
family continues to prove its superiority in rigorous testing
by the industry's leading OEMs, who are using it to deliver
the best possible video entertainment experience on any
screen in any room -- from the largest TVs, to displays
used for video gaming with the most rigorous performance
requirements."
Quantenna's QHS7xx family includes the QHS715 chipset for
demanding, high-bandwidth HD video entertainment applications,
and the QHS710 solution, which is designed for cost-sensitive,
mainstream IPTV deployments. In addition to using 4x4 MIMO
and both explicit and implicit digital transmit beamforming
technology to deliver superior performance, Quantenna's
unique architecture improves reliability by maximizing the
signal-to-noise integrity of each spatial stream using advanced
algorithms and modulation techniques. Quantenna 4x4 MIMO
technology also enhances coverage when connecting to non-4x4
MIMO clients, such as iPads or 2x2 and 3x3 MIMO clients
found in laptops.
According to In-Stat, there will be more than 200 million
web-enabled wire-line consumer electronic (CE) devices in
operation in the U.S. by 2014. When PCs and mobile devices
are added in, the average U.S. consumer household will own
between five and 10 Web-enabled CE devices. The firm reported
in November 2010 that over 53 million U.S. broadband households
currently view TV programs over the Internet, and 85 percent
of these users already view online TV content on multiple
devices, including personal computers, TVs and mobile handsets.
Carriers require sustained data rates of at least 120 Mbps
in order to deliver each video stream to these CE devices.
They also need near-perfect packet-error-rate (PER) data
transfer performance to provide enough quality and reliability
for the full range of entertainment applications such as
watching a full HD sporting event on a 72-inch screen, or
playing online multi-player role-playing games that require
low-latency performance using bidirectional controllers.
Quantenna's QHS7xx chipset delivers up to four simultaneous
video streams at data rates of 150 Mbps, each, to ensure
carrier-grade connection reliability and the best possible
viewing and gaming experience.
Quantenna's QHS7xx family is available now.
