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 .

UniFi® CSR6000™

CSR has introduced a new variant of the CSR6000™ family, the CSR6030 that supports Wi-Fi Direct™ Soft AP and Wi-Fi tethering modes of operations.

As the use of Wi-Fi in consumer electronics has become more widespread, the industry has continued to develop the way that Wi-Fi technology is used to make it more intuitive and also to enable new ways to connect the multitude of available devices.

In order to support all the latest use cases, CSR has introduced a new variant of the CSR6000 family, the CSR6030™.  Like its predecessors, CSR6030 supports IEEE 802.11b/g and n.
