Proposed FCC rules may smooth path to 5G wireless tech for US.


Mobile network traffic is heading in a direction that pleases many in the wireless industry. The Federal Communications on Thursday proposed new rules in wireless frequencies above 24 GHz.

The FCC news release read: “The FCC took steps today to maintain United States leadership in wireless by proposing new rules for wireless broadband in wireless frequencies above 24 GHz. These proposed rules are an opportunity to move forward on creating a regulatory environment in which these emerging next-generation mobile technologies – such as so-called 5G mobile service – can potentially take hold and deliver benefits to consumers, businesses, and the U.S. economy.”

It was previously assumed physical and tech limitations
could not support mobile service in these bands. New tech developments may allow the use of these high frequencies for mobile applications – like 5G service – with significantly more capacity and faster speeds for next generation mobile service.
Building off of years of successful spectrum policy, this NPRM proposes to create new flexible use service rules in the 28 GHz, 37 GHz, 39 GHz, and 64-71 GHz bands. The NPRM proposes to make these bands available using a variety of authorization schemes, including traditional wide area licensing, unlicensed, and a shared approach that provides access for both local area and wide area



HoloGrams new way to view our world.


As a student of electronics, I had to learn visualising the things, things that can be just drawn or not be seen by eyes. i had imagined electron fighting with each others and electricity and signals flowing. But Today I got a shock with this news of Microsoft HoloLens. It uses the Holograms and just change the world we look digitally. I cant express what it can do so I share the l;ink visit it and see a glimpse of future of our digital generation.

3D printing- Its more than just copying.


Last week china had made a history by printing 10 houses of 300 feet heights in 24 hrs, using 3D printers , and scientist had made a tumour model for study of typical concepts of this tumour using same technology. Lets know what and how about this technology here.

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, is a mechanized method whereby 3D objects are quickly made on a reasonably sized machine connected to a computer containing blueprints for the object. The 3D printing concept of custom manufacturing is exciting to nearly everyone. This revolutionary method for creating 3D models with the use of inkjet technology saves time and cost by eliminating the need to design; print and glue together separate model parts. Now, you can create a
complete model in a single process using 3D printing. The basic principles include materials cartridges, flexibility of output, and translation of code into a visible pattern.
3D Printers are machines that produce physical 3D models from digital data by printing layer by layer. It can make physical models of objects either designed with a CAD program or scanned with a 3D Scanner. It is used in a variety of industries including jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education and consumer products

The model to be manufactured is built up a layer at a time. A layer of powder is automatically deposited in the model tray. The print head then applies resin in the shape of the model. The layer dries solid almost immediately. The model tray then moves down the distance of a layer and another layer of power is deposited in position, in the model tray. The print head again applies resin in the shape of the model, binding it to the first layer. This sequence occurs one layer at a time until the model is complete.

Smart lights to enlight your shopping experience


Phillips recently introduced a system that connects in-store LED lights with consumers’ smart phones. Using a downloadable app, people will be able to locate items on their shopping lists or get coupons as they pass products on the aisles. Retailers can send targeted information such as recipes and coupons to consumers based on their precise location within stores, while gaining benefits of energy-efficient LED lighting, says Philips.

“The beauty of the system is that retailers do not have to invest in additional infrastructure to house, power and support location beacons for indoor positioning. The light fixtures themselves can communicate this information by virtue of their presence everywhere in the store,” said Philips Lighting’s Gerben van der Lugt in a statement.

The company is demonstrating the retail lighting system at the EuroShop retail trade show in Düsseldorf, Germany, this week. Philips is already testing it with an undisclosed number of retailers.

The system uses Visual Light Communications (VLC) to talk with consumers’ smartphones. Unlike the wireless protocols Wi-Fi, Bluetooth, and Zigbee, which use radio waves to send information, VLC relies on the store lights to transmit data to the camera on a smart phone in fast pulses. The lights blink at frequencies that are undetectable by people, according to LEDs Magazine.

There are already a number of other efforts aimed at adding communications and sensors to LED light fixtures. Last year, researchers at the University of Strathclyde in the U.K. demonstrated LED lights with optical communications, which they call “Li-Fi.” That setup was able to operate at gigabit-per-second speeds, according to a BBC article.

Startup ByteLight has developed a system similar to Philips’ retail lighting network. It also uses light pulses to communicate with consumers’ smart phones in stores. Other companies, such as Silver Spring Networks, in Redwood City, Calif., have developed street lights with sensors and radios that allow city managers to remotely monitor traffic density or air quality.


The New York Times today reported that the airport in Newark, New Jersey, is operating smart lighting systems with cameras that make it easier to monitor the facility. The lights allow personnel to spot long lines, look at license plate numbers, and potentially send alerts about suspicious activity.

But these smart lighting systems, while powerful, are raising concerns about privacy and whether new policies are needed to address this emerging technology. “There are some people in the commercial space who say, ‘Oh, big data—well, let’s collect everything, keep it around forever, we’ll pay for somebody to think about security later,’ ” Justin Brookman from the Center for Democracy and Technology told the Times.

In the case of Philips’ retail lighting application, consumers would have to download an app, which indicates their willingness to have their movements tracked. But as lighting and other everyday items such as thermostats and streetlights are equipped with sensors and wireless networking, it raises new questions about what is an acceptable amount of monitoring and data collection.

Businesses have a good economic incentive to network their lighting. By connecting lights with occupancy and daylight sensors to building management systems, they can greatly reduce electricity use—and energy costs—in commercial or institutional buildings.

Regardless of whether retailers adopt Philips’ smart lighting system, one thing is clear: the mobile phone in your purse or pocket is just one of a growing number of connected, smart devices in our daily environment.


Red Tacton: Beginning of Human Area Networking


Red Tacton is a new Human Area Networking technology that uses the surface of the human body as a safe, high speed network transmission path. Red Tacton uses
the minute electric field emitted on the surface of the human body. Technically, it is completely distinct from wireless and infrared .A transmission path is formed at the moment a part of the human body comes in contact with a Red Tacton transceiver. Physically separating ends the
contact and thus ends communication Using Red Tacton, communication starts when terminals carried by the user or embedded in devices are linked in various combinations according to the user’s Communication is possible using any body surfaces, such as the hands, fingers, arms, feet,
face, legs or torso. Red Tacton works natural, physical movements.


Using a new super-sensitive photonic electric field sensor, Red Tacton can
achieve duplex communication over the human body at a maximum speed of 10 mbps
The Red Tacton transmitter induces a weak electric field on the surface of the
body. The Red Tacton receiver senses changes in the weak electric field on the surface of the
body caused by the transmitter .Red tacton relies upon the principle that the optical properties of
an electro-optic crystal can vary according to the changes of a weak electric field. Red Tacton
detects changes in the optical properties of an electro-optic crystal using a laser and converts the
result to an electrical signal in a optical receiver circuit. The transmitter sends data by inducing
fluctuations in the minute electric field on the surface of the human body. Data is received using a
photonic electric field sensor that combines an electro-optic crystal and a laser light to detect
fluctuations in the minute electric field.

The naturally occurring electric field induced on the surface of the human
body dissipates into the earth. Therefore, this electric field is exceptionally faint and unstable.
The photonic electric field sensor developed by NTT enables weak electric fields to be measured
by detecting changes in the optical properties of an electro-optic crystal with a laser beam.


Sono : your next step to noise free indoor environment.


If you’re the sort that needs peace and quiet to get anything done, escaping the noise pollution of every day life — regardless of where you’re located — is no easy task. A white noise machine can help, but in the end it’s still electronic noise, and unless you can afford a fancy sound system, the noise often sounds unnatural. A new device that sticks onto your window, Sono, will not only cancel real-world noise, but isolate the noises you’d prefer to hear, if any.

That means the soothing sounds of chirping birds and the wind rustling through trees would make its way across the street and into your bedroom (even the horn of vehicles down the street is at its maximum). You could put on some noise-canceling headphones, but then you’ll have a huge pair of headphones tying you down; music doesn’t do the job white noise does, either. With Sono, you can stick the device right on your window, and fiddle with some settings to either cancel out noise entirely, or cancel out the specific noises that are drowning out the peaceful ones.

As you may have guessed, Sono does sound too good to be true within the realm of modern day technology, and it isn’t a product you can go out and purchase at the moment. Rather, it’s a concept created by Austrian industrial designer Rudolf Stefanich.  Sono works by vibrating a window in a pattern counter to the vibrations caused by the ambient noise, essentially turning the surface into a noise-canceling speaker. During prototype testing, Sono’s transducer used active noise canceling to successfully lower the audio signal by 12 decibels — which would probably do a good job of blocking out quieter sounds in the 30-80 dB range, but you’d still definitely hear traffic and other loud sounds.

The device employs concentric broadband antenna rings, and can be charged through WiFi signals or the standard electric outlet, so your noise shield won’t unceremoniously lower in the middle of the night.

The strength of Sono is not that it can cancel out obnoxious ambient noises, but can still filter pleasant ambient noises through. So, not only can you still get the chirping birds and rustling leaves from that park across the street, but the sounds are natural — not some recreation on your phone that sounds very digital. Though Stefanich’s device is more of a concept than a tangible item, the theory behind the device was successfully tested with that aforementioned prototype. Sono  environment is a finalist for the James Dyson Award, so it’s also getting a fair amount of recognition. Until Stefanich’s device can get production funding — and more testing, considering it sounds like it employs a dark magic to achieve the noise-filtering result — we’ll have to stick to our tinny-sounding white noise smartphone apps.


Micromax LapTab is here for you



In a first for an Indian phone company, Micromax showed its latest gadget – LapTab – at Consumer Electronics Show in Las Vegas on Monday. Micromax has built LapTab in partnership with Intel, which is pushing these hybrid devices capable of supporting both Android and Windows 8.1.

While more companies from across the world will come out with similar tablets – or maybe you can call them laptops that transform – Micromax is among the first companies in the world to prepare this hybrid device.
LapTab will launch in India in February. But the product is ready for the prime time.

In terms of hardware, there are two elements to LapTab. The first is the tablet. It has a 10.1-inch screen with a resolution of 1280×800 pixels. The screen shows decent colours but doesn’t match the contrast or richness of colours found on high-end tablets like Nexus 7 or iPad. Brightness too is on the lower side and could be an issue if you use the device under direct sunlight.

The tablet has a plastic body and does feel a bit cheap. But thankfully, there are no loose parts and there is no bending and creaking. Given it is all plastic, LapTab doesn’t feel too heavy in hand. In terms of connectivity and ports, there are lots of options. HDMI port is there and so is the micro USB 3.0 port, which is similar to the one found on Galaxy Note 3 and is backward compatible with micro USB 2.0. There is also a slot for microSD card. The tablet supports Wi-Fi and Bluetooth.

In terms of internal hardware, LapTab is well equipped. It is powered by a dual-core Intel N2805 processor. It runs at 1.46GHz and is fast enough, considering it is powering a device that has full version of Windows. The internal storage is 32GB or 64GB. LapTab has 2GB RAM.

The device has a touch sensitive home button with Windows logo.

The other part of the hardware is a keyboard cover. The build quality of cover feels slightly better than the tablet. The keys are nice and offer good amount of ‘clicky’ feel considering it is a thin cover. This is a pleasant surprise. However the finish of the plastic case attached to the keyboard could have been better. Its corners have sharp edges and taking out or putting the tablet back in the case takes some effort.

There is still a month to go so it is possible that Micromax will fix these minor flaws.

The keyboard and the plastic case connect with a flexible synthetic band, which can also act as a tablet stand, similar to how Apple’s official cover for iPad functions. There is a magnet inside this band and it attaches to the back cover of LapTab to form a stand.

While using LapTab, we tried both Android and Windows 8.1. When the device boots up, users get around 10 seconds to make a choice between Android and Windows. If you don’t select any OS, then the device boots in the OS that was running on it earlier. If you boot into Android, you get the familiar (almost) stock user interface of Ice Cream Sandwich aka Android 4.2.

The performance of the device is good though lack of tough glass makes the screen feel a bit less touch sensitive. But scrolling through lists and installed apps and pinch-to-zoom during web browsing is mostly smooth. Just to try out the hardware, we ran GeekBench 3, an app that measures theoretical performance of a processor, on LapTab. The device scored 599 points in single core benchmark and 1001 in multi-core. The single core score, which is more important, is above average. It is around 300 points less than the best performing mobile processors like Qualcomm Snapdragon 800. But it is almost 200 points better that the MediaTek processor found in phones like Canvas Turbo score. The multi-core performance is, however, average.

Under Windows too we found that LapTab performs well and without any significant lag. Almost all Windows applications are supported.

To summarize, LapTab is an intriguing product. Its utility is not yet apparent because hybrid devices tend to sacrifice some of the simplicity associated with tablets. Unless we use the device for a longer duration it is difficult to say if it offers more convenience than a standard tablet or a laptop or not.

There is also the matter of price and battery life. Without knowing the price and battery life of LapTab it is difficult to ascertain its value.

Rahul Sharma, Micromax co-founder who is in CES to show LapTab to media, believes that LapTab makes a lot of sense, especially for Indian consumers. “You don’t have to carry two devices… you can carry just one. LapTab is a laptop when you want the power of a laptop and it’s a tablet when you seek the convenience of a tablet,” he says.
