`Nokia's ultra-low-power Wibree joins Bluetooth
`Will enable wireless connections among smaller devices

`
`Ultralow power is being added to the features of short-range Bluetooth technology.
`
`The ultra-low-power Wibree technology developed by Nokia Corp. will become part of the Bluetooth
`
`specification under an agreement reached by the Wibree Forum and the Bluetooth Special Interest
`
`Group (SIG), the Finnish mobile phone maker said today.
`
`Bluetooth has been used mostly to connect larger devices such as headsets, keyboards and mice to
`
`stereos and PCs. With the help of Wibree, the technology will be able to connect smaller button-cell
`
`battery-powered devices, such as watches or sensors attached to a user's body. Wibree uses the same
`
`2.4-GHz frequency as Bluetooth.
`
`"We look at this as an addition to the Bluetooth family of specifications, enabling a new class of devices
`
`that Bluetooth isn't really suitable for today," said Michael Foley, executive director of Bluetooth SIG.
`
`In October, Nokia's research arm announced the development of Wibree and the establishment of an
`
`industry forum, whose members include Broadcom Corp. and STMicroelectronics NV, to define a
`
`specification.
`
`But after forming the forum, the companies -- many of them members of Bluetooth SIG -- decided they
`
`favored having ultra-low-power devices supported in Bluetooth, according to Harri Tulimaa, head of
`
`Nokia Technology Out-Licensing. "They didn't want to complete an entirely new technology," he said.
`
`The goal is to develop specifications for two types of ultra-low-cost implementations: a single-mode
`
`implementation for watches, sensors and other tiny devices to communicate with each other, and a
`
`dual-mode implementation to communicate with both single-mode and traditional Bluetooth devices.
`
`The core specification for ultra-low-power technology is already well advanced, according to Tulimaa.
`
`"We've started prototype interoperability testing between three companies and have transmitted packets
`
`over the air."

`
`Ultra-low-power Bluetooth will have a range up to 10 meters, similar to the Bluetooth Class 2
`
`specification, which requires more energy. A button-cell battery-powered device, equipped with ultra-
`
`low-power Bluetooth technology, will be designed to have an average operating life of one year,
`
`according to Tulimaa. It can transmit data at a speed up to 1Mbit/sec.
`
`High-power Bluetooth Class 3 has a range up to 100 meters.
`
`Foley doesn't view low-power Bluetooth as a competitor to Near Field Communications, another short-
`range wireless technology. NFC is designed primarily to help people make contactless transactions, he
`said.
`
`Bluetooth SIG expects to finalize ultra-low-power Bluetooth specifications in the first half of 2008, with
`
`the first products, most likely single-mode devices, to hit the market in the second half of the year.
