CSR today demonstrated its Ultra Low Power (ULP) Bluetooth, consuming 10 times less power than standard Bluetooth. ULP Bluetooth technology has very low overheads, which makes it much faster to connect devices and much less power consumed. End products based on ULP Bluetooth will have battery standby times measured in years, not just days or weeks.
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, the ULP devices used 1/10th the power required by standard Bluetooth.When ULP Bluetooth is used, in a wireless heart rate monitor for example, the monitor simply 'advertises' itself to the control/reader using three frequencies (could be a mobile phone or watch) that then connects sends its very short burst of data and then switches off again. This allows ULP Bluetooth to achieve data transfer 50-times faster than standard Bluetooth; less time spent transferring data means the ULP radio spends less time active. ULP Bluetooth is a complementary Bluetooth technology that can be used to transfer data sets between compact devices and is expected to be able to run for up to ten years on one button cell battery. The technology was previously known as Wibree.
