We are pleased to announce that as of August 13, 2015, Qualcomm Global Trading Pte. Ltd., a subsidiary of Qualcomm Incorporated, has completed its acquisition of CSR plc. For more information, please see the press release .


CSRC9300 combines auto-grade Wi-Fi®, Bluetooth® Smart and aptX® audio codec to differentiate cars.

The CSRC9300 enables next-generation 5GHz Wi-Fi connectivity with the 802.11a standard, which is set to support a number of exciting new applications for the car including in-vehicle video streaming. 

The chipset will also support the latest Wi-Fi features, including Wi-Fi direct and its services, which will enable more seamless Wi-Fi connectivity between cars and the latest smartphones on the market.  

The chipset also contains Bluetooth v4.0 support which enables low-power connectivity and basic data transfer for applications previously limited by the power consumption, size constraints and complexity of other wireless standards. 

In addition the chipset incorporates audio offloading capabilities such as on-chip support for wideband speech codec processing, and Advanced Audio Distribution Profile (A2DP) decoding for high-fidelity wireless audio.
