#Why Bluetooth use is on the rise Bluetooth has been with us for around 15 years.

Named after Denmark's King Harald Bluetooth Blatand, who reigned in the 10th century AD, it is a technology that everyone is aware of on their computers and phones,

yet not many people choose to use. As a means of allowing devices to talk to each other cheaply and wirelessly over short distances,

it has tended to stay largely in the shadows, leaving the limelight to the technologies it connects.

Now however, with the rapid growth in the use of mobile and sensing technologies along with the release of an updated version of the system,

and predictable technology,#says Professor Roch Guerin, Chair of Computer science and Engineering at Washington University, St louis."Bluetooth targets lower transmission ranges and data rates than wi-fi,

Bluetooth Smart, launched in 2011, includes a smarter power management system that allows it to turn on,

As a result, machines using Bluetooth that previously ran for a few months on a coin cell battery,

"Bluetooth classic is for sending steady streams of voice and audio,#says Suke Jawanda, Chief Marketing Officer of the Bluetooth Special interest Group (SIG),

which owns and licenses Bluetooth technology.""Bluetooth Smart is about sending packets of bits and data to applications.#

#Life changinghealthcare is cited frequently as one area that hasn't witnessed the radical transformations underway elsewhere as a result of the ongoing digital mobile revolution.

The growth of novel personal medical sensing technologies, many of which use Bluetooth, could soon change this.

Earlier this year, a Silicon valley-based start-up called Scanadu sought to raise $100, 000 on the crowd-funding site Indiegogo.

In fact donors pledged over $1. 6 million, making it the most funded project in the site's history.

The product description may have helped: the Scanadu Scout is described perhaps best as something approaching a real version of the medical tricorder wielded by Star trek doctor Leonard"Bones#Mccoy.

This data is transmitted via Bluetooth to users'phones or tablets. With recent advances in technology such as Bluetooth, we are now able to build medical devices that weren't possible just a decade ago#.

#at an affordable price using existing infrastructure of smart phone telecoms#says Scanadu's CEO Walter de Brouwer."

"For people who live far from hospitals, in places like Africa, this could be life changing.#

which is sent wirelessly via Bluetooth to an Android app, can be forwarded automatically to doctors. Bluecell is still a few years from commercialisation."

"We chose Bluetooth because of its wide distribution in consumer devices, #says Jacopo Olivo, one of the researchers."

"It's an interesting way that Bluetooth can interact with the biotech industry.##Other personal health sensors that use Bluetooth include the Cardiopad,

an electrocardiography (ECG) machine developed to monitor heart activity in patients in remote areas of Cameroon,

and sends that information directly to an ipad app via Bluetooth. By cross-checking this data against a database

Sensors could be linked via Bluetooth to sprinkler systems to automatically optimise moisture levels. The ability to use just the right amounts of water and fertiliser to produce a good harvest without wasting resources can improve crop yields and rural incomes.

Bluetooth is also being used to help those in agriculture in other ways. Kenyan mobile tech company Virtual city has developed Agrimanagr

an app designed to speed up and automate the flow of information and reduce costs for farming businesses.

electronic scales are used to transmit the weight of produce via Bluetooth to a mobile phone which records this in farmers'accounts on a cloud-based server.

#This system could of course be done without Bluetooth, but being wireless makes it easier.""Out in the rural areas,

With Bluetooth, our devices do that, and can work for 12 hours without electricity.##Bluetooth can also provide new ways of communicating in rural settings where internet access is unavailable or out of reach for the poor.

Gary Marsden, a computer scientist at the University of Cape town, developed Big board, an electronic notice board that disseminates information wirelessly and for free.

Users take a picture of an icon they are interested in with their phone and send it via Bluetooth to a nearby device which sends them the information they want.

Files can be pictures text, video or audio. Potential applications include distributing information on health, job offers or entertainment.

and the internet create and share content. This includes a solar-powered phone charging station and a Bluetooth-based local version of Dropbox

designed to allow off-grid communities to share and store information in a variety of formats.

Bluetooth Smart, like its older sibling, may be a relatively straightforward radio wave-based transmission technology. But as we devise more and more ways to benefit from ever greater connectivity between the people, other living organisms, objects and our environments,

it seems to be getting smarter by the day. If you would like to comment on this article

#Beating battery drain Stream video on your smartphone or use its GPS for an hour or two and you ll probably see the battery drain significantly.

As data rates climb and smartphones adopt more power-hungry features battery life has become a concern.

Now a technology developed by MIT spinout Eta Devices could help a phone s battery last perhaps twice as long

The primary culprit in smartphone battery drain is an inefficient power amplifier a component that is designed to push the radio signal out through the phones antennas.

Prepared to send sizeable chunks of data at any given time the amplifiers stay at maximum voltage eating away power more than any other smartphone component and about 75 percent of electricity consumption in base stations#and wasting

This means smartphone batteries lose longevity and base stations waste energy and lose money. But Eta Devices has developed a chip (for smartphones)

and a shoebox-size module (for base stations) based on nearly a decade of MIT research to essentially switch gears to adjust voltage supply to power amplifiers as needed cutting the waste.

When trialed in a base station last year Eta Devices module became the first transmitter for 4G LTE networks to achieve an average efficiency greater than 70 percent Dawson says.

Eta Devices has entered also conversations with major manufacturers of LTE-enabled smartphones to incorporate their chips by the end of next year.

Dawson says this could potentially double current smartphone battery life. Besides battery life Dawson adds there are many ways the telecommunications industry can take advantage of improved efficiency.

Eta Devices approach could lead to smaller handset batteries for example and even smaller handsets since there would be less dissipating heat.

and Twitter to name a few. In the mobile marketeta Devices commercial success is in part a product of engineering ingenuity intersecting with business acumen at MIT.

At the time I was suffering as everyone else was from my iphone running out of battery at lunchtime Astrom says.

The iphone was only a year old but you could see how much data traffic would explode.

A paper detailing the technology was presented at that year s IEEE Radio frequency Integrated circuits Symposium. That Deshpande Center grant was big in terms of the funding

A few major smartphone manufacturers are now using envelope tracking (ET) which adjusts voltage to power amplifiers on the fly.

But by adjusting that voltage continuously ET efficiency falls apart for 4G LTE and 802. 11ac (Wifi) wireless standards even up to 20 MHZ bandwidth.

ETADVANCED in contrast already accommodates ultrahigh bandwidths used by newer communication standards such as LTE Advanced (up to 80#megahertz) and the next-generation Wifi standard (up to 160 megahertz).

) Prepping for future communication standards is one thing that s helped the company thrive Dawson says.

pulling it slightly toward the leak site. That distortion can be detected by force-resistive sensors via a carefully designed mechanical system (similar to the sensors used in computer trackpads),

and the information sent back via wireless communications. Detecting leaks by sensing a pressure gradient close to leak openings is a novel idea

Depending on several site factors, this produces anywhere from 30 to 400 kilowatts of electricity. Treated wastewater exits the reactor with 80 to 90 percent of pollutants removed,
