CSR's Synergy wireless systems software is qualified to the Bluetooth v3.0 standard. Synergy operates at the heart of CSR's Connectivity Centre products, including the CSR9000 product, which features Bluetooth and Wi-Fi alongside several other technologies.

Bluetooth v3.0 offers a number of significant enhancements, including the potential for hugely increased speed and faster reactions to changing radio conditions.

Bluetooth v3.0 features 802.11 a/b/g AMP (Alternative MAC and PHY). AMP is featured in CSR’s Synergy and CSR9000, and allows Bluetooth to conduct high-speed, power-efficient file transfer in co-operation with IEEE 802.11.

When a Bluetooth device needs to transfer a large file, CSR's Synergy AMP has the ability to wake up the IEEE 802.11 radio to transfer files. This provides faster transfer times, and can also allow Bluetooth to transmit large files between devices using the most efficient radio technology available.

Bluetooth v3.0 also features support for Enhanced Power Control, which optimises the transmit power used in a connection even when a phone and a headset are suddenly moved apart from each other, or the phone is placed into a pocket. This lengthens battery life, ensuring that important phone calls are not lost.

"Bluetooth v3.0 marks the next stage in the evolution of Bluetooth," said Matthew Phillips, senior vice-president for CSR’s Handset Business Unit. "By combining the low power standby and familiar user experience of Bluetooth with the fast data-rates of IEEE 802.11, users can enjoy the ability to easily share files in a tenth of the time it currently takes. With music, picture and video files all increasing in size, there is strong demand for a high speed wireless solution for peer-to-peer and sideloading use-cases."
 
CSR's Synergy features in several of CSR's recent products, including CSR9000, which offers Bluetooth, Wi-Fi, Bluetooth low energy, GPS and FM Rx/Tx. As the software behind such a comprehensive product, CSR's Synergy complies to the Bluetooth v3.0 spec and supports all Wi-Fi variants, and also offers support for additional technologies such as Bluetooth low energy, FM and GPS.
