CSR (Cambridge Silicon Radio), a leading provider of single chip radio devices, today announced that Bellwave Co. Ltd., the Korean mobile phone and data module design company, has selected CSR's BlueCore silicon for a new Bluetooth enabled GPRS handset design. Bellwave is supplying its i100(TM) handset design to one of the largest electronics groups in China, which plans to promote the i100 GPRS handset to the international market, as well as the rapidly expanding Chinese mobile phone market.

In addition to high-speed GPRS, Bellwave's i100 mobile phone design offers a built-in VGA camera and imaging software; Windows style full color graphical user interface; Java for downloading new games and applications; WAP and MMS. CSR's BlueCore silicon was selected by Bellwave to enable Bluetooth wireless connectivity between the i100 and a Bluetooth headset or for synchronization with a Bluetooth enabled PC.

Bellwave is supplying the i100 phones together with a number of other GSM and GPRS models to leading Chinese OEMs.

Jeffrey Kang, Bellwave's COO, commented, "The Chinese market is demanding mobile phones with more than just the basic features -- consumers are asking for features such as GPRS for access to high-speed data services and Bluetooth for local wireless connectivity." Kang continued, "Our turnkey handset designs are intended to enable high-volume low cost production. CSR helps us maintain our competitive edge with its BlueCore Bluetooth technology by boosting the functionality of our designs, and without pushing costs beyond the reach of our customers."
