Nokia unveils better Bluetooth wireless connection
HELSINKI - Mobile phone market leader Nokia unveiled a newshort-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 put it through a standardisation process along
with a number of other wireless technology firms. When Wibree has become a standard, the technology
would be available to anyone at the same reasonable terms. "Our aim is to establish an industry standard
faster than ever before by offering an inter-operable solution that can be commercialised and incorporated
into products as quickly as possible," Iannucci said. Like Bluetooth -- used to link cellphones with headsets,
computers and printers to transfer calls, calendar items, documents, songs and pictures -- Wibree provides
a radio link of up to 30 feet between devices.
LINKING SMALLER DEVICES TO PHONES
Because of their low energy consumption, Wibree radio chips will make it possible and efficient to connect
phones and other electronics devices to low-power watches, sports sensors, wireless mice or health monitors,
which often have not 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, business development manager at Nokia Research Centre 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 available during the second quarter of next year,
while products using Wibree should 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 Bluetooth-Wibree chip, while devices that are not connected now will use a Wibree-only chip. Bluetooth
technology was invented by Ericsson in the 1990s and subsequently given away to the market as an open
standard. "Bluetooth is clearly not suited to some of the cooler applications like intelligent jewellery, watches --
a less power hungry, smaller, cheaper solution will open some interesting new opportunities," said Ben Wood,
director at U.K.-based Collins Consulting. While Bluetooth is looking for ultra high frequencies above
6 gigahertz for faster connections, Wibree will operate in the 2.4 gigahertz band, sharing it with many
technologies. Wibree technology would eventually add a few cents on top of current prices for Bluetooth chips,
Iannucci said. Finnish-based Nokia said companies working with it on defining the standard are Broadcom
Corp., CSR Plc, Epson, Nordic Semiconductor, Taiyo Yuden Ltd and Amer Sports unit Suunto. "I guess the
challenge is getting industry-wide support for yet another wireless 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.
Shortwave broadcast transmissions cut back
Radio broadcasters are increasingly cutting back on their shortwave transmissions, according to a new report
published in the International Herald Tribune. The report, written following the demolition of 13 shortwave
radio antenna towers in Spain, suggests that many radio broadcasters are increasingly moving away from
shortwave to new forms of communication such as Internet radio and podcasting. Some companies are
considering phasing out shortwave altogether. Even BBC Word Service -- the leading international radio
broadcaster -- is reviewing its shortwave services. But fans of shortwave have leapt to the technology’s
defence. They argue that it is one of the most reliable means of communication and highlight how it has
allowed broadcasts to be heard by people in repressive countries even when FM and internet broadcasts
have been blocked. During the Cold War, international broadcasters used shortwave to spread their message
over the Iron Curtain. The history of shortwave can be traced back to 1927 when Dutch company Philips
Laboratories undertook shortwave broadcasts from Eindhoven to the Dutch East Indies. To see the
