QUALCOMM Incorporated, pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced the successful completion of the world's first Bluetooth(tm)-to-WCDMA (UMTS) voice calls.
Bluetooth technology, offered as part of QUALCOMM's wireless Launchpad(tm) suite of applications, is a short-range wireless radio solution that eliminates the need for wired connections between digital devices. The WCDMA voice calls were made under laboratory conditions using commercially available Bluetooth headsets interfacing with QUALCOMM's MSM6200(tm) Mobile Station Modem (MSM) chip on a Subscriber Unit Reference Development System (SURF) platform. Voice calls were both originated from and terminated at the Bluetooth headset. Bluetooth-to-GSM voice calls were also demonstrated using the same MSM6200 chipset and SURF platform.
QUALCOMM's single-chip MSM6200 multimode WCDMA/GSM/GPRS baseband processor is the first commercially available device that offers integrated Bluetooth technology and other Launchpad applications. In addition to Bluetooth and other connectivity technologies, the Launchpad suite encompasses advanced multimedia, position location, user interface and removable storage capabilities. Select components of the Launchpad suite are integrated into all of QUALCOMM's MSM chipsets, based on the market for which each chip is designed, to help facilitate a broad range of new handsets, applications and Internet-based services.
"While many companies are trying to achieve WCDMA voice calls, we have combined our growing WCDMA expertise with our proven Launchpad technologies to demonstrate a fundamental consumer capability," said Johan Lodenius, senior vice president of marketing and product development for QUALCOMM CDMA Technologies. "QUALCOMM recognizes that consumers care most about useful features on their handsets that provide a greater variety of services. Bluetooth and other Launchpad features are intended to help consumers in their everyday lives, and to do it transparently."
The MSM6200 chipset is QUALCOMM's second-generation WCDMA solution and supports data rates of up to 384 kbps. Like all members of the MSM6xxx family, the MSM6200 solution incorporates QUALCOMM's radioOne Zero Intermediate Frequency (ZIF) architecture, which eliminates the need for IF components, including large IF SAW filters and additional IF circuitry. With radioOne technology, the MSM6200 solution requires less printed circuit board area than previous generation chipsets and reduces bill-of-material costs for dual-mode handsets.
In addition to selected features of the Launchpad suite of technologies, the MSM6200 solution supports QUALCOMM's Binary Runtime Environment for Wireless (BREW) platform's Application Programming Interface (API). With the BREWapi, handset manufacturers and developers can develop both embedded and downloadable wireless applications and BREW-based products more quickly and easily.
The MSM6200 chip sampled in June 2002. The full MSM6200 solution, including radioOne ZIF RF technology, is now available.
