Broadcom Delivers VoIP/Wi-Fi Chipset

Wi-Fi phones based on this chipset will offer consumers a cordless phone  replacement that can also support data applications such as web browsing,  email and instant messaging.  This solution is based on the convergence of  Broadcom’s award-winning 54g wireless LAN (Wi-Fi) and field-proven Voice  over Internet Protocol (VoIP) technologies.  When compared to similar  solutions, Broadcom’s Voice over wireless LAN (VoWLAN) chipset reduces major  chip count from four to two chips, and offers additional important features  such as quality of service (QoS) and security.

“Our research indicates the number of broadband IP telephony subscribers  will increase with a compound annual growth rate of 122 percent year-to-year  in the US from 2004 through 2008,” said Keith Nissen, Senior Analyst for In- Stat/MDR.  “By 2008, there will be approximately 75 million subscribers using  Wi-Fi-based voice services in the US, and over 145 million subscribers  worldwide.  Wi-Fi Phones will help drive the adoption of VoIP by enabling the  delivery of advanced VoIP services such as unified messaging and presence  directly to the handset.”

“There is a lot of discussion around ‘convergence’ in the industry.  With  its proven ability to integrate, Broadcom is bringing to the market a real  example of convergence that will enable a new class of phones,” said Robert A.  Rango, Group Vice President of Broadcom’s Mobile & Wireless Group. “As the  worldwide leader in Wi-Fi and an emerging leader in VoIP customer premises  equipment (CPE) solutions, it is a natural step forward for us to combine  these two technologies onto one platform for the development of wireless IP  phones.”

Industry Leading Integration

Broadcom’s wireless IP phone chipset solution consists of the Broadcom  BCM1160 mobile VoIP processor and BCM4318 AirForce One 54g chip.  These  two chips are shipping today and together enable a complete wireless VoIP  handset solution that offers a future-proofed platform capable of supporting  emerging Wi-Fi and VoIP standards, as well as new data and multimedia  applications over an 802.11g Wi-Fi connection. 

The BCM1160 is a new Broadcom mobile VoIP processor specifically designed  to meet the integration and low-power requirements of wireless handheld  devices.  The BCM1160 integrates an ARM9-based CPU, analog voice codec  with a direct microphone and high-output speaker interface, 1.3 megapixel  camera interface, 262k color LCD display interface, and USB into a single-chip  solution.

The processor uses Broadcom’s xChange VoIP software for supporting the  transport of toll-quality voice.  xChange is a robust, field-proven, modular  software architecture used across all of Broadcom’s VoIP silicon platforms,  including Wi-Fi and desktop Ethernet IP phones, residential terminal adapters  and voice-enabled cable and DSL residential gateways.  It has been shipped in  more than four million devices to date.

The BCM4318 is Broadcom’s smallest and most cost-effective 54g  transceiver, integrating a high-performance 2.4 GHz radio, IEEE 802.11a/g  baseband processor, medium access controller (MAC) and other components onto a  single silicon chip.  The BCM4318 supports Broadcom’s SecureEZSetup and  its SmartRadio technology enables wireless VoIP phones to maintain  connectivity at greater distances from the wireless router. Broadcom has been  an industry leader in promoting interoperable Wi-Fi products. Broadcom’s  client and access point Wi-Fi reference designs are included in the Wi-Fi  Alliance test bed for 801.11b, 802.11g, 802.11a/g, Wi-Fi Multimedia (WMM),  Wi-Fi Protected Access (WPA), and WPA2.

To reduce customers’ time-to-market with new product designs, Broadcom has  developed the BCM91160 Wi-Fi VoIP phone reference design.  The BCM91160  includes Broadcom’s xChange VoIP software, Session Initiation Protocol (SIP)  call signaling stack, WLAN OneDriver and a LinuxOS-based board support  package, including all necessary drivers and software development tool chain.   This kit is available today to developers as a wireless IP phone handset with  a comprehensive hardware reference design support package.

Broadcom plans to demonstrate the BCM91160 reference design at the Fall  2004 VON Conference & Expo, Oct. 18-20, at the Sheraton Boston hotel connected  to the Hynes Convention Center in Boston, MA.
