Radiolab 3G Modeling Toolset Leverages MathWorks MATLAB(R);

To Be Highlighted At 3GSM World Congress This Month In France

RadioScape Ltd, leading providers of software-defined radio (SDR) products for the digital wireless broadcast and communications markets, today announced its new Radiolab 3G UMTS/W-CDMA system-level design toolset, the most complete set of design modeling elements commercially available for these emerging cellular standards. Designed by 3G developers for 3G developers, the toolset enables more accurate and faster development of 3G UMTS/W-CDMA solutions by removing key barriers to the development and availability of new wireless communications services.

Radiolab operates with MathWorks MATLAB(R) and Simulink(R), the world's most popular system-level design and modeling environment. Using its powerful SDR development approach, RadioScape has significantly extended the capabilities of Simulink, enabling it to handle bursting variable-sized data, a vital functionality for 3G simulation. This advance gives 3G developers a tool for simulations and rapid development of 3G basestations and handsets, before committing designs to silicon chipsets.

"The 3GPP UMTS standard is significantly more complex than GSM, requiring more powerful tools to ensure robust solutions and rapid implementation," said RadioScape CTO Gavin Ferris. "RadioScape's Radiolab 3G system-level design tools provide bit accurate simulations and software models that are fully compliant with the 3GPP FDD specifications and are ideal for the development of both basestation and handset products. These capabilities substantially reduce the risk of error, the number of failed designs and the time to market of many 3G engineering products. This has a direct effect on the bottom line for 3G developers - resources are better utilized, and results are achieved earlier."

"By enhancing and leveraging the power of MATLAB and Simulink, RadioScape's product makes robust W-CDMA simulation available to a wide audience for the first time," said MathWorks Director of DSP and Communications Marketing Ken Karnofsky. "Since it's compatible with other MathWorks products for communication system development, engineers can add their own intellectual property to RadioScape's standards-compliant reference designs."

With more reference systems than any other product, the Radiolab 3G W-CDMA modeling toolset includes a comprehensive library of models and simulations including Turbo and Viterbi coding, transport and physical channels, Multi-user detection (MUD) and Multi-path radio channel simulation, all in easy-to-use forms. The software can model the key functions of a W-CDMA basestation, providing unmatched flexibility for both UTRAN and UE designs. Furthermore, Radiolab's toolset supports full rate-matching and de-rate matching for uplinks and downlinks. Radiolab can also be extended to support fixed-point, bit-true modeling for the design of DSPs and FPGAs.

Each of the tool's elements has been designed to conform to the appropriate UMTS specification. The Radiolab UMTS/W-CDMA Blockset and Reference Systems Version 1.0 will be available in March 2001.

Notes to Editors

A full list of the reference systems that will be present in the first release of the FDD blockset is available upon request.

RadioScape will be exhibiting at the 3GSM World Congress in Cannes, February 19-23. During this time they will be holding briefings about the Radiolab 3G, tailored for both engineers and journalists. RadioScape will also be hosting a journalist hospitality evening on Thursday, February 22.

About RadioScape

RadioScape Ltd. (www.radioscape.com) is an UK-based leading developer of software-defined radio products for the digital broadcast and digital wireless communications market. RadioScape's success to date is attributable to its software defined radio approach to development and its underlying architecture and development platform for digital communications - The Communication Virtual Machine. This software platform was designed and developed by RadioScape to enable it to develop rapidly software and products for new digital standards and has been used to deliver commercial products for digital radio and 3G/UMTS/W-CDMA international standards.

In January 2001, Texas Instruments announced its TMS320DRE200 chipset, which uses RadioScape's software-defined radio (SDR) to deliver digital radio for the consumer market.

RadioScape's investors include Texas Instruments, Atlas Ventures, JAFCO, Psion, and ntl:.
