#Wi-fi Aware enables location-based apps without GPS, cell service A new Wi-fi technology will soon let smartphones

and other Wi-fi enabled devices easily find each other and communicate without a cellular or internet connection or GPS.

Wi-fi Aware is a way for devices and apps to scan their surroundings for other devices

and apps they might want to connect to and exchange small messages before making a more solid Wi-fi connection.

Some uses suggested in a promotional video including: Finding someone to play a game with on a subway train.

The new technology was announced this week by the Wifi Alliance, a collaboration of companies involved in making

or selling Wi-fi devices or components, including Apple, Microsoft, Sony, Intel and Samsung. Location-based services have been billed as a convenient way to target information to people, such as shoppers,

In Wi-fi Aware-certified devices, the service runs continuously in the background, looking for services

users who find what they're looking for can establish a more solid connection via Wi-fi,

or Wi-fi Direct, which allows some devices to connect directly without an internet connection. Regular Wi-fi has sometimes been blamed as a battery drain in smartphones

but the Wi-fi Alliance says Wi-fi Aware operates in a very power efficient way"through a unique process of discovery

and synchronization, establishing a common'heartbeat'".'"Works indoors, in crowds It's billed as working well even indoors somewhere GPS doesn't work very well,

Wi-fi Aware will also work in crowded places like concerts and protests without a cellular, Wi-fi or GPS connection.

Its range is similar to that of a regular Wi-fi connection several dozen metres. So far, the Wi-fi Aware technology has been incorporated into a wireless chips from Broadcom, Intel, Marvell and Realtek."

"Wi-fi Aware closes many of the gaps preventing other technologies from offering a rich experience where users can fully engage with the world around them,

"said Clint Brown, director of product marketing for Broadcom Corp.,in a statement. Existing technologies used for location-based services all have weaknesses.

GPS doesn't work well indoors, regular Wi-fi is not very power efficient, NFC has an extremely short range,

and Apple's ibeacon, based on Bluetooth Low energy (BLE) is designed to work only with Apple devices. ibeacon:

How much privacy would you give up for a coupon? This week, Google announced its own competitor to ibeacon, known as Eddystone,

which can be compatible with any Bluetooth Smart device, regardless of whether its Apple, Android,

Kevin Robinson, director of product marketing for the Wi-fi Alliance, said another advantage of Wi-fi Aware over beacon technologies is they offer only one-way conversations."

"Wi-fi Aware enables a two-way conversation that doesn't rely on the cloud.""For example, he said,

But Wi-fi Aware would let the app ask about wait times at that and nearby security checkpoints o

A company called Energous is on hand at CES with a demo of its new wireless power system known amusingly as Wattup.

It uses a mix of Bluetooth and RF to combine the convenience of wireless power with the security of a wireless network.

Devices that want to receive power from the hub announce their presence via Bluetooth 4. 0. Wattup then uses that connection to direct the wireless power signal to the device.

It operates in the same unlicensed spectrum as Wifi, which makes me wonder about possible interference in busy wireless environments.

Some experiments in long-range wireless power have forced simply brute their way through this problem to the point that they actually heat up the air around the transmitter.

That Bluetooth connection is used to focus a tight cone of electromagnetic waves on the target, and it can even track the device and recalibrate as needed.

so why not your wireless power network? The Bluetooth tether that is used to direct beam-forming can also authenticate devices.

Wattup can operate in protected mode where only authorized devices can connect, or in public access mode where anyone with the hardware can soak up some electrons (controlled via an app).

#Indian-Origin researcher uses Wi-fi to power camera In a first such demonstration, an Indian-origin researcher has developed a system that uses Wi-fi Internet signals to beam power to remote

the system is known as power-over-Wi-fi. The idea is simple in concept. Wi-fi radio broadcasts are a form of energy that a simple antenna can pick up.

Until now, Wi-fi receivers have all been designed to harvest the information that these broadcasts carry. Talla simply connected an antenna to a temperature sensor

placed it close to a Wi-fi router and measured the resulting voltages in the device and for how long it can operate on the remote power source alone.

Even more ambitiously, the team also connected a camera to their antenna. This was a low-power sensor capable of producing 174×144 pixel black and white images,

we charge a Jawbone device in the vicinity of the power-over-Wi-fi router from a no-charge state to 41 percent charged state in 2. 5 hours,

#Patient safety driving increased RFID use in hospitals The University of Vermont Medical center in Burlington, Vt.

announced recently that five million medications have been tracked using radio frequency identification technology. Adam Buckley, MD, interim chief information officer and chief medical informatics officer at UVMC, said any time a system allows a hospital to track reliably from ordering through dispensing through administration at the bedside,

A vial of the drug Glycopyrrolate with a strength of 1mg/ML became the five-millionth RFID-tagged dose at UVMC tracked by Kit Check, a Washington, D c,

Karen Mcbride, UVMC's director of pharmacy services, said that patient safety was the main reason for utilizing RFID technology."

and that the RFID kit technology essentially eliminates that possibility. The way Mcbride explained it,

preparation and administration, said Kitcheck"has succeeded out of the gate"by applying RFID tags to anesthesia kits, already operational in over 100 hospitals.

Neuenschwander noted that in the past RFID companies thought at a universal rather than a macro level,

For example, MEPS Real-time Inc. a company that offers a suite of Intelliguard RFID Solutions, has shifted its from focus from macro to micro RFID solutions,

and track bullets throughout hospitals'pneumatic transport tubes with RFID. RFID vs. barcode Despite the progress RFID has made in the hospital setting, the debate over

which technology will sustain over the long hall, RFID or bar code, is ongoing among industry experts.

According to Neuenschwander, each technology has its advantages and disadvantages. Barcodes, he said, are less expensive data carriers than RFID chips.

And RFID chips have higher read-failure rates than bar codes.""Proximity reads are an advantage when

I want to read everything that is in a kit, as opposed to handling and scanning items one by one,

Why RFID hasn't been applied to drug packaging for point-of-care verification scanning? Neuenschwander said that he doubts

if RFID chips will ever displace barcodes on drug packages any more than on cereal boxes in grocery stores.

Rather, he contends that RFID will augment printed codes on a select number of items."

however, RFID is more than just a mirage on the frontier, he said:""RFID has materialized finally beyond prototypes to products that are live in hospitals today,

"said Neuenschwander. UVMC's Buckley said that people are going to figure out the best way to leverage RFID technology."

"Whether it will be the best way to leverage it or whether the price will be cost-prohibitive

"Going forward, UVMC said that its next step is to talk to Kitcheck about leveraging similar RFID technology in the OR setting."
