Bluetooth Congress

AMSTERDAM, Netherlands--(BUSINESS WIRE)--June 13, 2002

CSR (Cambridge Silicon Radio) today helped to demonstrate IPv6 running over Bluetooth during the Bluetooth Congress presentation by Jawad Khaki, corporate vice president of Windows Networking and Communications at Microsoft.

The demonstration, using a CSR Bluetooth chip with on-chip IPv6 stack, between a DVD player and a Microsoft Windows XP notebook PC, integrated a web server running directly on CSR's BlueCore2 Bluetooth chip into a consumer DVD player. This first demonstration of IPv6 running over Bluetooth wireless technology shows how standard Internet solutions can be used with Bluetooth. A standard web browser accesses the web server resident on the Bluetooth chip in the DVD player to provide the user interface in the browser on the PC. While this demonstration shows the PC in close proximity to the DVD player, it could reside anywhere on the Internet enabling remote control of IPv6 devices.

"Connecting and controlling a wide range of devices through the Internet is a prime goal of IPv6. This goal is now achieved for any Bluetooth enabled device via BlueCore2," said Eric Janson, vice president CSR North America. "CSR is delighted to be working with Microsoft to make this vision a reality."

In his presentation, Ubiquitous Wireless Networks, Khaki said, "CSR is one of the early players to integrate full IPv6 connectivity into a single Bluetooth device. Microsoft's work with CSR has been important to the early implementation of universal connectivity based on IPv6 in combination with Bluetooth in Windows XP."

In December 2001, CSR announced it would be working with Microsoft Corp. to support Internet Protocol version 6 (IPv6) over Bluetooth(TM) by providing an IPv6 stack to run on its BlueCore2 single-chip solution. This allows Bluetooth devices to be easily enabled with Internet connections without including their own IP stack.

CSR supports the concept of a web-based browser acting as a universal interface to a range of consumer and industrial products. For example, a heating controller using Bluetooth can be controlled from a remote PC running Microsoft Windows. Microsoft Corp has indicated that it will provide Bluetooth profile support for Windows XP in 2002, that it will include the use of Universal Plug and Play technology for device discovery and use IPv6 over Bluetooth for the Personal Area Networking profile.

IPv6 overcomes the shortcomings of the current protocol, IPv4, by expanding the available address space from 32- to 128-bits. This will allow every electrical and electronic device in the world to be allocated a unique IP address.

At last year's Bluetooth Congress in Monaco, CSR demonstrated how, using its first generation BlueCore01, Bluetooth could access a web server; this was based on the same concept. CSR's BlueLab Bluetooth software will support IPv6 using the Bluetooth SIG-defined network encapsulation protocol (BNEP) in addition to the RFCOMM and HID protocols it currently supports.

About CSR

CSR (Cambridge Silicon Radio) specializes in providing single-chip radio devices to the global market for short-range wireless communications, including Bluetooth(TM). The company's mission is to create the most highly integrated radio devices available, fabricated using standard CMOS technology, to provide its customers with the lowest cost of ownership of high quality digital radio.

CSR was the first company in the world to offer a true single-chip Bluetooth solution with BlueCore, a fully integrated 2.4 GHz radio, baseband and microcontroller. In Q4 2001 CSR released BlueCore2, its second generation family, and offers developed hardware/software bundles for each of the fastest growing Bluetooth applications markets. Users can combine the chips with the CSR Bluetooth software stack to provide a fully compliant solution for data and voice communications or, used with an upper layer host software stack, CSR is able to offer a complete Bluetooth end-to-end solution.

CSR has a growing list of major international companies including Sony, Compaq, IBM, Fujitsu, LG, ALPS, TDK, 3Com, Mitsumi, Siemens and Motorola, who have already used CSR's BlueCore in the development of a range of Bluetooth products. In fact, up to the end of 2001, 70% of available pre-qualified modules, as listed on the qualified products page of the Bluetooth Special Interest Group (SIG) web site, feature BlueCore01 and it is in 60% of all qualified Bluetooth v 1.1 enabled end product designs.

CSR is headquartered in Cambridge, UK, with offices in Richardson, Texas; Tokyo, Japan; Singapore and Aalborg, Denmark.
