Broadcom adds chips for Wi-Fi 802.11n products
Broadcom introduced several new chips that can be used in advanced Wi-Fi products based on the 802.11n version of the standard.
Wi-Fi 802.11n still has not yet been formally ratified as a standard, though commercial products based on the draft standard are already available. It is an amendment that provides for multiple input/multiple output (MIMO) streaming.
The 802.11n version provides for a theoretical maximum data rate of 300 Mbps. The aim of 802.11n is to provide a more useful wireless backbone, capable of reliably carrying multiple high-quality video streams throughout networked homes.
Broadcom introduced three new 802.11n chips in its Intensi-fi line. The Intensi-fi XLR chips provide for simultaneous dual-band routers for high-definition (HD) video streaming. They are based on Broadcom’s Accelerange technology, a set of hardware and software enhancements that ensure more robust wireless coverage in the far corners of a home.
The Broadcom BCM4716, BCM4717 and BCM4718 provide different mixes of features for products (routers, gateways, set-tops, etc.) that can be introduced at different price points.
The BCM4716, BCM4717 and BCM4718 wireless LAN (WLAN) solutions are now sampling to early access customers, with production quantities expected to ship in the third quarter of 2008. Pricing is available upon request.
At the same time, Broadcom announced a single-chip dual-band 802.11n solution for universal serial bus (USB) adapters.
It is aimed at very small and cost-effective USB adapters that consumers can use to connect PCs, TVs, set-top boxes, personal video recorders (PVRs) and other devices to a Wi-Fi network.
The BCM4323 USB solution is also a member of the company’s Intensi-fi family of chips and also relies on the company’s Accelerange technology.
It is now shipping in production volumes. Pricing is available upon request.
