Qualcomm Conducts Live Demonstrations of radioOne Technology for CDMA2000 1X

date: March 18, 2002

Qualcomm, pioneer of CDMA digital wireless technology, today announced live voice and data calls using Qualcomm’s radioOne Zero Intermediate Frequency (Zero IF) direct conversion technology. These calls represent the world’s first public CDMA voice and data demonstrations using direct conversion technology on 3G CDMA2000 1X chipset solutions.

Over-the-air voice call demonstrations used the Qualcomm CDMA Technologies (QCT) MSM6000 Mobile Station Modem (MSM) solution which includes the QCT RFL6000, RFR6000, RFT6100 and PM6000 chips. The MSM6000 chipset and system software supports tri-mode operation [cellular CDMA, PCS CDMA and Advanced Mobile Phone Service (AMPS)].

3G CDMA2000 1X over-the-air data calls are being demonstrated using the QCT MSM6050 chipset, featuring the QCT RFL6000, RFR6000, RFT6100 and PM6050 chips, with a laptop as the display device. Supporting quad-mode operation (cellular CDMA, PCS CDMA, AMPS and gpsOne position location technology), the MSM6050 solution enables advanced multimedia applications such as streaming video and wireless Internet browsing at data rates of up to 153kbps.

"The CTIA radioOne direct-conversion RF demonstrations represent an important milestone in the wireless industry, both for CDMA and for future multimode, multiband devices," said Don Schrock, president of Qualcomm CDMA Technologies. "Qualcomm is committed to continuing to bring to market the benefits of innovative technology to our customers, which in turn will provide consumers with cost-effective, feature-rich third-generation wireless handsets."
