Nokia's low-power link to be new Bluetooth standard

The mobile handset firm's ultra low power short-range wireless technology is to be developed as a new version of Bluetooth to connect devices like watches and heart monitors.

Mobile handset firm Nokia's ultra low power short-range wireless technology is to be developed as a new version of Bluetooth to connect devices such as watches and heart monitors, the company said on Tuesday.

An agreement to use the Nokia technology as the basis for an ultra low-power Bluetooth standard should help to speed its use and acceptance rather than be a competing technology, the Bluetooth SIG industry interest group said.

Michael Foley, Executive Director of the Bluetooth SIG, said product developers had been calling for an ultra low power standard, which should now be finalised in about a year.

"I would see the products coming relatively quickly after the specs are done," he told Reuters.

The Wibree short-range radio link -- likely to be marketed as ultra low power Bluetooth -- uses just a fraction of the power of earlier systems and can hook up devices with small batteries or power capacity.

That could allow links for toys, sports monitors and watches, as well as sensors used in health monitoring, which have not been able to use Bluetooth until now because of its power demands.

Nokia has worked since 2001 on Wibree, which provides a radio link of up to 10 metres (30 feet) between devices.

Nokia sees new market

Harri Tulimaa, head of Nokia's technology outlicensing, said the deal should result in a new open market for devices that can communicate with each other, as well as with mobile phones, which are the main users currently of Bluetooth technology.

"The capability of addressing and connecting low power devices should actually also bring a boost to the traditional Bluetooth," Tulimaa said.

He said the Finnish-based mobile company had been somewhat over-optimistic when it said last October that it expected the first commercial version of the standard to be ready in the second quarter of this year.

And while developing the technology as a Bluetooth standard could take a bit longer, it would help the standard to be accepted.

"I think we will see some evolution in the industry in the coming few years in the area of ultra low power," Tulimaa said, adding that the industry had not accepted earlier proprietary technology in that field.

First to come were likely to be devices with only ultra low power versions, followed by some which combine both Bluetooth wireless connections.

Jari Honko, analyst at eQ Bank in Helsinki, said Nokia appeared willing to share some ideas "in order to avoid fragmentation of that particular market".

"It seems Nokia sees it as wise not to keep some technology for itself, (avoiding the) danger that some competing company should create some competing technology," Honko said.

Shares in Nokia were down 1.3 per cent by 1236 GMT, compared to a DJ Stoxx technology index off 1.1 per cent.

Bluetooth is used to link cellphones with headsets, computers and printers to transfer calls, calendar items, documents, songs and pictures.

It was invented by Ericsson in the 1990s and subsequently given to the market as an open standard.

While Bluetooth operates with ultra high frequencies above 6 gigahertz for faster connections, Wibree is intended to operate in the 2.4 gigahertz band, and the two would be able to work in parallel.

Nokia said companies that had contributed to developing the standard included Broadcom Corp, CSR Plc, Epson, ItoM, Nordic Semiconductor, STMicroelectronics, Taiyo Yuden Co Ltd, Texas Instruments and Amer Sports unit Suunto.
