Broadcom Launches Three More 802.11g Wireless Products

6/27/2003 - Broadcom Corporation (Nasdaq: BRCM), the leading provider of silicon solutions enabling broadband communications, announced three additions to its wireless LAN product portfolio: the industry’s first 802.11g and 802.11a/g USB 2.0 adapters for consumer and corporate desktop computing systems; and a new wireless networking processor for secure 802.11a/g enterprise access point and router applications. With these new devices, Broadcom extends its leadership as an innovator of wireless LAN technology and expands the broadest solutions portfolio in the industry.

Broadcom was the first vendor to ship solutions based on IEEE 802.11g, which is expected to become the new mainstream 54Mbps wireless LAN standard, and 54gTM is Broadcom’s maximum performance implementation of the 802.11g standard that provides optimum speed, range and security capabilities. According to leading market information company The NPD Group, Inc., Broadcom has shipped 93% of all 802.11g connections sold through U.S. retail distribution channels. Additionally, all 802.11g-enabled notebooks that have been sold to date by major PC vendors are based on Broadcom® 54gTM technology.

“Broadcom is expanding 54Mbps wireless networking applications beyond notebook connectivity,” said Jeff Abramowitz, Senior Director of Broadcom’s Home and Wireless Networking Business Unit. “IEEE 802.11g, the new mainstream wireless LAN standard, and Broadcom’s standards-based XpressTM technology increase available bandwidth to enable more wireless LAN devices to share the network. Our new reference designs build on the success of our 54gTM product line and enable our customers to achieve maximum performance and security in new WLAN platforms.”

Industry’s First 802.11g and 802.11a/g USB 2.0 Adapters for Desktop Systems
Broadcom is the first to offer both 802.11g and 802.11a/g USB 2.0 adapters for desktop systems. By pairing 54gTM MaxPerformance with the high-bandwidth USB 2.0 interface, equipment vendors can provide a simple upgrade path to 54Mbps for home and enterprise computing systems. The USB interface gives users the ability to easily add standards-compliant 802.11g and 802.11a/g to desktop systems without removing the PC chassis cover. USB 2.0 technology delivers 480 Mbps of bandwidth, which is necessary to support 54Mbps wireless connections, while legacy USB 1.1 systems are capable of only 12Mbps.

“Buffalo recently became the first vendor to enter the market with a 54gTM USB 2.0 adapter,” said Morikazu Sano, Vice President of Buffalo Technology. “Our affordable, easy-to-use wireless LAN solutions for desktop computers allow consumers to connect without the cost and effort of running wires through the house, and allow businesses to avoid the high cost of employee moves, adds and changes.”

Broadcom’s 802.11g and 802.11a/g USB 2.0 adapters are based on the company’s BCM94333U reference design. The complete design package includes the BCM4333 802.11 bridge processor and OneDriverTM USB 2.0 software development kit (SDK) in conjunction with Broadcom’s 802.11g or 802.11a/g chipset. Customers benefit from Broadcom’s reference design offering because it provides complete customization of features such as ease-of-use, security, and branding that are not possible with turnkey solutions. As a result, partners can leverage their existing expertise with Broadcom WLAN devices and software products to create differentiation in their end products.

AirForceTM BCM4704P High-Performance Wireless Networking Processor
Broadcom’s new BCM4704P wireless network processor is the next-generation of the company’s BCM4702, which is currently the most popular wireless network processor in the industry. The BCM4704P adds a network processing core that is capable of wire-speed Ethernet routing/bridging, as well as virtual private network (VPN) termination on an integrated IPSec security acceleration engine. These features make this processor an obvious choice for enterprise customers who need both high-bandwidth performance and advanced security features such as encryption and user authentication. The BCM4704P and the BCM4702 both use the same AirForceTM OneDriver software, simplifying customer migration.

The BCM4704P integrates an advanced, custom 300 MHz MIPS32Ô processor core, two 10/100 Ethernet MACs, and a high-performance SDRAM controller capable of operating at 133MHz with either Double Data Rate (DDR) or Single Data Rate (SDR) SDRAM.

For advanced security, the BCM4704P integrates an on-chip IPSec acceleration engine that can deliver up to 75Mbps of single-pass AES/3DES encryption throughput and supports a broad range of industry-standard security features, such as symmetric-key encryption and authentication algorithms including the latest 256-bit Advanced Encryption Standard (AES), Digital Encryption Standard (DES), 3DES, SHA-1, MD5, HMAC-SHA1 and HMAC-MD5. Additionally, the BCM4704 is available for customers seeking increased network processing performance in applications without on-chip IPSec acceleration and it is pin compatible with the BCM4704P.

Xpress Technology Enhances Performance
All of Broadcom’s wireless solutions can be enhanced with its newly announced standards-based Xpress technology, which increases throughput by improving the efficiency of wireless transmissions. Performance gains afforded by Xpress technology are not limited to 802.11g or Broadcom products. Any 802.11 client adapter can receive Xpress technology packets and achieve better throughput. This is especially beneficial in many corporate networks that include equipment from multiple vendors. In homes, the additional bandwidth provided by Xpress will improve performance as consumers add wireless LAN-enabled devices to their home networks including desktop PCs, printers, handheld devices and media servers.

Broadcom’s AirForce Wireless LAN Product Family
Broadcom’s high performance AirForce wireless LAN product line features the greatest breadth and depth in the industry. In addition to transceivers that provide IEEE 802.11g, 802.11b and dual-band 802.11a/g solutions, Broadcom integrates wireless network processors, communications technologies and software solutions into reference designs that speed customers’ time to market.

The AirForce family includes 54gTM, the premier technology for 54 Mbps wireless LANs in home, offices and public hot-spots. Solutions based on 54gTM technology provide the highest throughput and range, and are completely interoperable with the 40 million 802.11b nodes currently in service. Broadcom partners, including Apple, Belkin, Buffalo/MELCO, Cisco/Linksys, Dell, Fujitsu, Gateway and HP, have implemented 54gTM technology in notebook PCs, client devices, access points, routers, cable modems, DSL modems and GPRS cellular products.
