HSDPA

Dual-Mode 3G/4G Solution

UbiNetics and Renesas Technology Corp. have signed an agreement for the development of the first RF (radio frequency) solution capable of supporting W-CDMA and HSDPA (High Speed Downlink Packet Access) in the frequency bands used in Japan, Europe, and the US. HSDPA is the high-speed data transmission system which accelerated W-CDMA. Its system realizes 14.2-Mbps maximum high-data transmission speed. The announcement marks the second time the companies have partnered for joint RF solution development.

QUALCOMM Expands Product Portfolio With New WCDMA 3G Solutions

QUALCOMM Incorporated, pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced the Mobile Station Modem(TM) (MSM(TM)) MSM6255(TM) chipset and system software to enable cost-effective WCDMA (UMTS) and GSM/GPRS/EDGE solutions. QUALCOMM has extended the success of the commercially available MSM6250(TM) chipset to deliver the MSM6255 chipset, a highly integrated multimedia solution for WCDMA and GSM/GPRS/EDGE networks worldwide.

Siemens to Bring the First HSDPA Solution to Market

Siemens Communications will be the first vendor to bring an end-to-end solution for “High Speed Downlink Packet Access” (HSDPA) to market, complete with PC card. This UMTS extension will enable operators to significantly boost data rates in UMTS networks and provide their subscribers with average download speeds of up to 2 to 3 megabits per second. That roughly corresponds to what the fastest DSL connections are currently capable of offering. In January 2005, Siemens will be conducting the first live demonstrations with a HSDPA network.

DoCoMo & TI to Develop Multi-Mode UMTS

Texas Instruments Inc. and NTT DoCoMo, Inc., have announced a joint agreement to develop a cost-competitive, multi-mode UMTS (W-CDMA/ GSM/GPRS) chipset to serve the Japanese, U.S. and worldwide 3G handset market. An integrated UMTS digital baseband and applications processor will be developed based on TI’s OMAP(TM) 2 architecture and NTT DoCoMo’s W-CDMA technology for NTT DoCoMo handsets and other 3G handsets worldwide. Additionally, the agreement will include development and testing of power management, RF and protocol software that will be made available as system solutions to TI’s worldwide customer base.

QUALCOMM Introduces First Dual-Mode Chip for WCDMA and GSM/GPRS/EDGE

QUALCOMM Incorporated pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced further steps to reduce development costs for WCDMA (UMTS) markets worldwide with the introduction of the radioOne(TM) RTR6275(TM) solution. The RTR6275 device is the wireless industry’s first single-chip RF CMOS (Complementary Metal Oxide Semiconductor) transceiver for dual-mode WCDMA (UMTS)/HSDPA and GSM/GPRS/EDGE (EGPRS) terminals.

Vodafone K.K. Testing Flash-OFDM

Vodafone’s answer to 3.5G and NTT DoCoMo’s HSDPA will be trailed here later this year. Vodafone will be conducting fast low-latency access with seamless handoff Orthogonal Frequency Division Multiplexing (Flash OFDM) trials in the second half of the year in Tokyo that will test the ability to run 3Mbps wireless data networks.
