HELSINKI (Reuters) - Cell phone market leader Nokia unveiled a new short-range
wireless connection on Tuesday that is smaller and more energy-efficient than
current Bluetooth technology and can be used in devices such as watches.
The new radio technology, dubbed "Wibree," can work alongside Bluetooth short-
range wireless connections but use just a fraction of the power.
"It's up to 10 times more energy efficient than Bluetooth," Bob Iannucci, head
of Nokia Research Center, told a news conference.
Nokia said it had worked for five years to develop the technology and would pu
t it through a standardization process along with a number of other wireless t
echnology firms. When Wibree has become a standard, the technology would be av
ailable to anyone at the same reasonable terms.
"Our aim is to establish an industry standard faster than ever before by offer
ing an inter-operable solution that can be commercialized and incorporated int
o products as quickly as possible," Iannucci said.
Like Bluetooth -- used to link cell phones with headsets, computers and printe
rs to transfer calls, calendar items, documents, songs and pictures -- Wibree
provides a radio link of up to 10 meters (30 feet) between devices.
LINKING SMALLER DEVICES TO PHONES
Because of their low energy consumption, Wibree radio chips will make it possi
ble and efficient to connect phones and other electronics devices to low-power
watches, sports sensors, wireless mice or health monitors, which often have n
ot been able to use Bluetooth technology due to its power demands.
"Bluetooth is widely used in phones. Smaller devices around the phone is where
the big problems are, and we want to create the link there," Jani Tierala, bu
siness development manager at Nokia Research Center told Reuters.
"We believe that the use-cases are relevant enough to enough firms to see the
value in this," he said.
Nokia said it expected the first commercial version of the standard to be avai
lable during the second quarter of next year, while products using Wibree shou
ld follow soon after that. Nordic Semiconductor said it will be ready to ship
Wibree chips by the second half of 2007.
Nokia expects devices currently connected by Bluetooth will get a dual Bluetoo
th-Wibree chip, while devices that are not connected now will use a Wibree-onl
y chip.
Bluetooth technology was invented by Ericsson in the 1990s and subsequently gi
ven away to the market as an open standard.
"Bluetooth is clearly not suited to some of the cooler applications like intel
ligent jewelry, watches -- a less power hungry, smaller, cheaper solution will
open some interesting new opportunities," said Ben Wood, director at UK-based
Collins Consulting.
While Bluetooth is looking for ultra high frequencies above 6 gigahertz for fa
ster connections, Wibree will operate in the 2.4 gigahertz band, sharing it wi
th many technologies.
Wibree technology would eventually add a few cents on top of current prices fo
r Bluetooth chips, Iannucci said.
Finnish-based Nokia said companies working with it on defining the standard ar
e Broadcom Corp., CSR Plc, Epson, Nordic Semiconductor, Taiyo Yuden Co. Ltd an
d Amer Sports unit Suunto.
"I guess the challenge is getting industry-wide support for yet another wirele
ss standard, given the overwhelming number of standards in play at the moment
its hard to see how companies can justify the R&D commitment to all of them,"
said Wood.
