CSR today gave the first public demonstration of its Ultra Low Power (ULP) Bluetooth silicon. CSR gave the successful demonstration at the Continua Health Alliance medical conference in Luxembourg. The demonstration is said to have shown that CSR¹s ULP Bluetooth silicon consumes 10 times less power than standard Bluetooth when connectable. Other participants in the medical conference included the Bluetooth Special Interest Group (SIG) and Nokia.
CSR¹s ULP Bluetooth demonstrations consisted of two ICs successfully transferring ULP Bluetooth data packets 50-times faster than standard Bluetooth, meaning that the devices were consuming as little as 1/50th of the power. In addition, in establishing the connection, the ULP devices used 1/10th the power required by standard Bluetooth. CSR¹s demonstration ICs employed both standard Bluetooth (v.2.1) and ULP Bluetooth radios. CSR calls these devices Œdual-mode because they support both flavours of Bluetooth radio.
ULP Bluetooth is a complementary Bluetooth technology that can be used to transfer simple data sets between compact devices and can run for up to ten years on one button cell battery. ULP Bluetooth was previously known as Wibree.
