Broadcom has launched two new WiFi devices to enable a consumer
video experience that spans mobile devices, smart TVs and other consumer
The new products include Broadcom's first combo chip
optimized to add dual-stream, dual-band WiFi and Bluetooth 4.0
connectivity to CE devices and an integrated wireless dongle design that will bring WiFi Display (now called WiFi Miracast) to existing digital TVs and media boxes.
With wireless connectivity attach rates in smart TVs, set-top boxes,
streaming media boxes and other products expected to grow to almost 50%
over the next four years, Wi-Fi will increasingly become a primary
channel by which video and other media reach the CE device. Similarly, smartphones
and other mobile devices have become important platforms for viewing
digital content and now occupy an important role in how people access
and enjoy media.
The new Broadcom BCM43242 features dual-band multiple input, multiple
output (MIMO) WiFi technology to enable integrated dual video streaming
and over-the-top capabilities in CE devices, supporting features such as
advanced error correction and simultaneous WiFi connections to two
devices. This allows a smart TV to simultaneously access Internet
content and stream high-bandwidth video from a smartphone,
tablet or PC. The chip can also enable peer-to-peer transmissions in
the 5 GHz band, with more spectrum and less congestion in that frequency
range allowing better quality video streaming and smartphone-to-TV
With integrated Bluetooth 4.0, the new combo device will enable CE products to use advanced remotes, game controllers, stereo headphones,
keyboards, 3D glasses and other interface devices. Broadcom Bluetooth
also features the ability to stream audio to home stereos, enable voice
recognition in remote controls and connect smartphones and other devices
to the CE ecosystem, driving innovation in user interface development.
The BCM43242 includes Broadcom's best-in-class InConcert co-existence
technology--with key optimizations for DTV use cases--that enables
uninterrupted Bluetooth connectivity while maintaining high Wi-Fi
Broadcom's new wireless dongle design features the proven capabilities
of the BCM43236 dual-band Wi-Fi chip and the low power, high performance
BCM2835 VideoCore media processor, enabling cost-effective adapter
products that easily add WiFi Display capabilities to existing CE
devices with an HDMI port. The ability to conveniently use the larger
screens of digital televisions for viewing content is driving adoption
of WiFi Display, which couples Wi-Fi and video encoding technology to
allow the consumer to seamlessly move the mobile user interface from a
small screen to a bigger display while maintaining control via the
mobile's touch screen.
The dongle platform is designed to support zero packet loss, minimize
latency for interactive use cases and mitigate interference while
maximizing screen resolution and picture quality for WiFi Display
applications. Broadcom's VideoCore processing technology enables vivid
graphics and HD video playback with minimal power consumption.
Further driving adoption and use of WiFi Display, Broadcom has
integrated support for the technology into several of its key smartphone
platforms, including its BCM28155 3G HSPA+ dual-core SoC, so that
handsets based on Broadcom smartphone platforms that include the BCM4334
smartphone combo chip will also be able to offer these media streaming
capabilities. Wi-Fi Display support is also planned for all future
Broadcom dual-core smartphone platforms.
The BCM43242 is now sampling to Broadcom's early access
customers, with full production expected in Q4 2012. Broadcom's
integrated WiFi Display dongle design is also sampling to customers,
with the BCM43236 Wi-Fi chip and BCM2835 media processor shipping in
