CSR has integrated Bluetooth low energy, eGPS and FM Tx and Rx technologies into BlueCore7 alongside an enhanced Bluetooth v2.1 + EDR radio which delivers +10dBm Tx and -91 dBm Rx. These enhancements help BlueCore7 to extend the overall range and across-body performance to provide better audio quality (think handset on one side of the body and headset on diagonally opposing ear). BlueCore7 allows the Bluetooth and FM radios to work without interference, either independently or together to allow users to stream FM radio from a handset to a pair of Bluetooth headphones.

In April, CSR gave the world’s first public demonstration of Bluetooth low energy technology. Bluetooth low energy (previously known as Ultra Low Power Bluetooth or Wibree) uses fewer frequencies to make connections while retaining the proven robustness of Bluetooth. BlueCore7 is available in QFN and WLCSP packaging and will be in volume production from Q4 2008.
