Single-chip, dual-band IEEE 802.11n USB adapter SoC solution from Broadcom

The BCM4323, a new single-chip dual-band 802.11n USB solutions from Broadcom that integrates high-performance Power Amplifiers (PAs) in a single monolithic CMOS die and leverage USB interfaces to add high performance Wi-Fi connectivity to PCs, TVs, set-top boxes (STBs), broadband modems, Blu-ray Disc players, and other consumer electronics devices.

The Intensi-Fi XLR Wi-Fi media family consists of a 2x2 2.4 GHz only solution (BCM43235) for internet connectivity applications, a fully integrated dual-band radio transceiver with 2.4 GHz and 5 GHz band transmission capability (BCM43236) for home video streaming applications, and a fully integrated dual-band radio transceiver with custom enhancements and software to support carrier-grade IPTV applications (BCM43238).

The key features of the Wi-Fi USB adapter solutions are,

An ARM host offload-processor and RAM reduces wireless tasks from the host processor, enabling the device to achieve maximum Wi-Fi performance with no incremental load impact vs. wired Ethernet
Data rates up to 300 Megabits per second (Mbps) and TCP throughput of 200 Mbps over short distances and guaranteed, robust throughput of 40Mbps+ at the edge of a >3000 ft(2) home
Bill of material (BOM) cost reductions by up to 40 percent
65 nanometer CMOS design that promotes high integration and low power consumption
Broadcom's OneDriver software support and WHQL certified driver support for Windows Vista, Windows XP and Windows 2000 operating systems for client applications.
Linux support for access point and router applications

Broadcom has also announced a new Intensi-fi XLR wireless LAN (WLAN) router system-on-a-chip (SoC) solutions with accelerange technology that enable 2x2 802.11n routers to provide a strong wireless backbone for the networked home.

The Intensi-fi XLR SoC solutions, Wi-Fi system OEMs can leverage unparalleled silicon integration to reduce the overall cost while still maintaining adequate multiple-input and multiple-output (MIMO) performance for streaming HD video throughout the home.

Bill Bunch, Director of Broadcom's Wi-Fi Media line of business said, "Broadcom has proven itself as a leader in 802.11n Wi-Fi media solutions with design wins shipping in high-volume products from the top consumer electronics OEMs. With this next generation family of products we are delivering a large cost reduction, setting the stage for much higher attach rates of Wi-Fi in DTV, Blu-ray, and set-top box products. In addition, we are raising the bar in the industry by offering the carrier-grade performance and quality of service necessary to stream HD video reliably throughout an entire home in a compact and inexpensive form factor that our competitors are not able to match. As a result, end users will be able to wirelessly share and enjoy media content using internet-based applications as connected TVs become ubiquitous."

Philip Solis, Practice Director, ABI Research said, "Simultaneous dual-band 802.11n is important for consumers who want to move entertainment content throughout their homes without cords or wires. Utilizing both parts of the spectrum multiplies the available bandwidth to support high-quality media streaming, deliver faster downloads and enhance online gaming. Sales of 802.11n routers will outpace 802.11g routers in 2010, as consumers seek faster and more reliable wireless connectivity."
