CSR’s v2.0+EDR BlueCore4 silicon has been chosen by ASUS to Bluetooth-enable its latest slim-line notebook computer. The ASUS W6A is the first laptop model in Taiwan to offer the higher-speed Enhanced Data Rate (EDR) Bluetooth. ASUS is the third computer manufacturer, after Dell and Apple, to adopt BlueCore4 in order to offer its customers data transfer rates three times faster than v1.2 Bluetooth products.

CSR's BlueCore4 with Enhanced Data Rate Bluetooth offers transfer rates of up to 3 Mbps, compared with the 1-Mbps rate of previous Bluetooth specifications. This feature allows more simultaneous Bluetooth connections to be sustained, thus supporting the use of a Bluetooth mouse and keyboard while sending a document to print to a Bluetooth-enabled printer, listening to music from the PC on Bluetooth stereo headphones, and transferring photos over a Bluetooth link to another PC or PDA, with no impact on connection stability or performance.

In addition, because the data transfer rate is three times faster than conventional Bluetooth, power consumption is drastically reduced, as the Bluetooth radio is active for one-third of the time required to send the same data by v1.1 or v1.2 Bluetooth.
