BROADCOM LAUNCHES SOLUTION FOR BLUETOOTH/WI-FI COEXISTENCE.
"The convenience and freedom enabled by wireless communications technologies are changing the way we access networks and use electronic devices in the enterprise, the home and on the road," said Jeff Abramowitz, Sr. director of marketing for Broadcom's Wireless LAN products. "Wi-Fi and Bluetooth have independently become mainstream technologies and Broadcom's InConcert technology optimizes how they work together in the same devices. This is an essential feature as multiple wireless technologies converge into individual products like PCs, PDAs or mobile phones."
InConcert Technology is a system solution that leverages hardware built into Broadcom's Bluetooth and Wi-Fi solutions. The software required to enable InConcert Technology resides within Broadcom's Blutonium Bluetooth system firmware and OneDriver unified wireless LAN driver. Any device that uses both Bluetooth and wireless LAN chips enabled with InConcert will automatically and intelligently synchronize its wireless transmissions to avoid interference. The technology is critical for devices such as PCs, handheld computers and smart phones that integrate both technologies to maximize mobility and convenience.
"InConcert Technology is Broadcom's latest innovation in response to a customer need. We've added the industry's most advanced solution for collaborative coexistence to our best-of-breed Bluetooth and wireless LAN solutions, " said Scott Bibaud, director of Bluetooth Marketing at Broadcom. "Using prioritized coordination, InConcert technology elegantly addresses the coexistence problem for customers looking to build multi-radio technology devices ."
2.4 GHz Increasingly Popular for Wireless Communications
The 2.4 GHz radio frequency band is used for a number of consumer and enter prise applications, including those that are equipped for Bluetooth and IEEE 802.11b and 802.11g wireless networking. In addition, these channels are also used for such devices as wireless video cameras and cordless phones. Adaptive frequency hopping (AFH), a Bluetooth 1.2 feature that Broadcom has already introduced in its products, can be used to mitigate radio interference in this common frequency, minimizing the possibility of performance degradation. For products like laptops or PDAs that incorporate both Bluetooth and wireless LAN technology, however, AFH is not sufficient to fully prevent interference.
InConcert technology alleviates this problem by having Broadcom Bluetooth and wireless LAN products work together to establish and adhere to a digital transmission synchronization scheme, ensuring that radio transmissions among products enabled with InConcert avoid collisions and find the clearest channels and time slots for operation. In network environments with Broadcom-enabled wireless products, all constituent devices can work together to facilitate maximum wireless performance.
Broadcom Uniquely Situated to Solve Co-Existence Problem
With the industry's broadest product lines for Bluetooth and wireless LAN, as well as cellular solutions, Broadcom is uniquely suited to address radio interference issues between these technologies. Broadcom's Blutonium line of Bluetooth products includes the BCM2040, currently the only available system-on-a-chip solution for wireless keyboards and mice, the BCM2002 radio-only device, and single-chip integrated baseband and radio solutions, such as the BCM2040, BCM2035 and BCM2033. The BCM2035, BCM2033 and BCM2002 are currently in high volume production with several major cellular phone and other product manufacturers.
Broadcom's high performance WLAN product line, AirForce, features the greatest breadth and depth in the industry. In addition to transceivers that provide IEEE 802.11b, 802.11g and dual-band 802.11a/g solutions, Broadcom integrates wireless network processors, communications technologies and OneDriver software solutions into reference designs that speed customer time to market. Broadcom recently expanded its wireless family to include AirForce One, the world's first single-chip wireless LAN solution that enables Wi-Fi connectivity in pocket-sized mobile devices.
All the wireless chips in Broadcom's Bluetooth and Wi-Fi product lines enjoy unique performance advantages such as improve throughput and range via Broadcom's SmartRadio technology. In addition to advanced signal processing techniques, the all-CMOS solutions are capable of self-calibrating based on usage temperature and other environmental conditions, reconfiguring constantly for optimum performance. Competing radios are statically calibrated at the point of manufacture and are unable to adapt to changing environmental influences.
InConcert technology appears in Broadcom's Bluetooth and wireless LAN products, which are fully compatible with previous generation Broadcom wireless chips.
