In 2011, Harald Hass, a scientist at the University of Edinburgh, proved that with a single LED could transmit more data than a phone mast. Haas said that an LED bulb can use Internet to transmit ultrafast way.
It has been four years since its discovery, but it was until 2015 when tested outside laboratory.
technology was called Li-Fi and tests in 2015 have incredible results, as it has been shown that lifi can be up to 100 times faster transmission than WiFi.
The expectations have been surpassed, as is has achieved transmission speeds of up to 1GB of data per second.
Literally, with this technology the data communication is carried out through light and can certainly revolutionize the way the world uses Internet in the near future.
It has already been proven that the Li-Fi works on mobile and companies like Samsung and LG, and other electronics manufacturers are already interested in making smartphones with light sensors Li -Fi.
Another advantage of this new technology is that it has proven to be safer than WiFi and not interfere with other systems, so it could be used safely in an airplane for example.
The Li-Fi technology uses visible light for this transmission and only uses a light emitting diode LED
With the Li-Fi lamp would have two functions:. providing light and ensure connectivity to the router (router).
The introduction of Li-Fi in everyday life, will begin to do gradually.
Initially, this will be used in conjunction with wifi, which will create faster and secure networks.
Researchers are working on the adaptation of existing devices to be compatible with Li-Fi.
For now there is a pilot project, creating a Li-Fi network to have Internet in offices. PureLifi addition, the company created by Haas and his team, offers a secure implementation of wireless access and the French company Oledcomm Li-Fi and installed in hospitals.
This technology is just beginning to show its potential, because in Oxford University have achieved to 22GB per second.
WhatsApp enabled the option to free calls between its users
The voice calls or video calls for free from smartphones WhatsApp revolutionized communication.
The free instant messaging applications to revolutionize the smartphone arrived form of communication between people. In such a growing and market hundreds of competitors, WhatsApp became the world leader and in 2015 gave a big surprise to users.
At the end of March 2015 was realized something many already expected and others believed impossible. WhatsApp made available an update in which the option to make free voice calls between users of the application included
The simple fact of offering voice calls over IP to more than 700 million users, free it was a sociological and technological milestone.
This offered a great advantage of communication for people who are in different countries and even for those who simply want to reduce their call charges each month.
The option also offers the possibility to make video calls from smartphones with others who have WhatsApp application. However, when the option began to be used many users began reporting that calls consumed too much data, or quickly reduced the amount of Internet data available to use per month.
In July 2015 , WhatsApp incorporated a low-power mode data voice calls, which can be activated in the configuration. Today WhatsApp voice calls are already key global communication.
Lily, the drone following its user and records
The drone follows the wearer a device location.
It is increasingly common to use drones ( UAVs) in the world and in 2015 an invention brought to another level. This is called “Lily Camera”, a device weighing only 1.3 kilograms. Unlike other drones that are designed only to fly, “Lily Camera” automatically focuses on a target.
The minidrón not take control tablet or application to manage remote, as it works with the System Global Positioning System (GPS) tracking bracelet that must take whoever wants to be recorded by “Lily Camera”.
The camera takes pictures at a resolution of 12 megapixels, records videos in sizes of 1080 and 720 pixels, and stores them in MP4 format on a micro SD card. To start flight “Lily Camera” is thrown into the air and land it is pressed a button on the scanner. The bracelet has an accelerometer and position sensors that determine the speed and trajectory of the individual wearing it.
Lily reaches a speed of 40 mph and rises to a height of 15 meters. Both ‘Lily’ as the locator are waterproof, something ideal for recording extreme sports.
Safety Truck, which prevents the truck accidents
The truck carries a screen showing the road.
Each year worldwide die more than a million people in traffic accidents, according to statistics from the World Health Organization (WHO). So constantly work on new ways to reduce risks while driving is one of the greatest challenges facing automakers.
In 2015, the South Korean electronics firm Samsung unveiled its project called “Safety Truck” . The concept is simple, but revolutionary
a camera is installed in the front and four giant screens behind
These screens show, united in one image what the camera captures.. The road and what’s in it. This prevents the drivers behind the truck try to pass when cars coming in the other lane, and thus one of the most common forms of accident is avoided.
It’s like the trailer to become clear . When the car is placed behind the truck, four giant monitors allow the driver to see how traffic flows ahead of these giants of the road and safely calculate the time to overtake. In addition, it anticipates braking and collisions with obstacles on the road, as animals or trees.
Oculus Rift virtual reality helmet
Who uses the hull is immersed in virtual reality.
For years, the chance to swim in virtual reality was just a dream movie, but now it’s finally here.
In 2015 was presented the invention Oculus Rift, a virtual reality helmet developed by Oculus VR, which in its time as an independent company invested $ 91 million to make the invention work.
The helmet Oculus Rift was presented in June 2015 and are already several companies working on similar projects.
This invention will allow users to be “trapped “in virtual reality, either in video games and other interactive activities.
confirmed that Oculus Rift begin to be sold to the public in early 2016.
The retail model of Oculus Rift initially operate with a command of Xbox One and will have a minimum bid of eight games. The company also develops the project Oculus Touch drivers whose own developing prototypes Half Moon has named and designed specifically for the user to interact with objects and people in a virtual reality.
Revolution of cars that drive themselves
Until NASA working on these prototypes.
In 2015 the autonomous car, or conducting themselves alone, they ceased to be controlled laboratory experiments or environments.
Last October the company Peugeot Citroen proved an autonomous vehicle in the streets and roads of France, where normally circulated conventional cars with their drivers. The prototype successfully ran 580 kilometers. It was from Paris to Bordeaux without driver intervention. He even overtook other cars and did speed changes.
The rise of these autonomous vehicles is such that even Nissan and NASA working on the development of these, like Google.
modular Smartphones, armed by the user
The Ara project will be launched in 2016.
Put together a smartphone at will and is a real possibility for the user.
The buyer can now decide what type of camera, keyboard, screen or speaker will have your smartphone.
These smartphones are called “modular telephones”, are assembled as modules from which you can choose the user to arm the smart phone to your taste.
Since last month October 2015, in Europe several users who made their orders have begun to receive the Fairphone 2, which is armed to his will.
If you want to change a piece, like the camera, just remove a module and They buy one and put it on your smartphone. This implies an advantage, either to replace damaged parts or to update your phone without buying a new one.
Google is also working on modular smartphones, work they have called “Ara Project”. He was going to put on sale in 2015, but to provide better decided product to be distributed in the market until 2016.
Researchers tested several cars can be hacked
Chris Valasek (left) and Charlie Miller (right) exposed the vulnerability of several vehicles that could easily be hacked by experts.
In July 2015 researchers did shake the automotive industry, after demonstrating that a car could hack away and take control.
This tested it researchers Charlie Miller and Chris Valasek, who conducted the kidnapping remotely hacking a Jeep Cherokee driven by a news reporter.
Among the vehicles vulnerable to such attacks are the Jeep Cherokee, Chrysler 200 and Dodge Ram, according investigation disclosed.
Hackers can cut the brakes, turn the engine off the road and upset all the electronics.
After this, they were sent to review more than one million cars to try to correct the vulnerability.
The place where you could make these hacks was in the United States.
The problem was caused by a fault in the Uconnect wireless service that connects these cars network Sprint cell phone.
“Right now I could do that to each vehicle Chrysler in the United States on the Sprint network,” Miller said in an interview, after demonstrating how they could hack vehicles. The researchers did not rule out other types of vehicles, which they did tests, can be hacked too.
In 2013, Miller and Valasek had already proven how could hack a car, but then needed to be at his inside and physically connect a laptop to the dashboard.
But now that wireless connectivity is in almost all cars in the United States can hack from afar. With a laptop carts were searched in the Sprint network that have the Uconnect system. Within seconds, they were able to get into any “system of info-tainment” of these vehicles.
They begin to use floating skateboards
In the 1989 movie, “Back to the Future II”, Marty McFly, It starring Michael J. Fox, traveled to the future, to October 21, 2015 to try to fix what would be his life. In one scene, chasing McFly to hit him, but escapes using a floating skateboard.
In that year, 1989, that scene seemed impossible to become reality, but just in 2015, as “predicted “Film, the company Lexus unveiled its prototype Slide, a floating skateboard.
In August 2015, Lexus revealed that built a special park for demonstrations. The floating skateboard coat on a special track and uses multiple magnetic superconductors cooled with liquid nitrogen to work.
The Slide weighs about nine kilograms and its operating time is about 20 minutes.
After this time, it’s back to cool the magnet for about 10 minutes. That is, at least for now, the skateboard can not float on any surface, but the achievement of creating a floating skateboard, regardless of the surface, is seen as a breakthrough that sets the course for future popular use.
increase artificial intelligence Watson
Watson is a computer system capable of answering questions in natural language artificial intelligence. It was developed by the IBM Corporation.
Answer the questions through a database stored locally, whose information comes from several sources, including encyclopedias, dictionaries, news articles, and external databases.
In 2015 IBM acquired the company to integrate its technology AlchemyAPI to Watson and increase intelligence system, making you learn from conversations, digital text and photographs.
successfully installed with smart pavement
The routers are installed under the floor.
When the invention “Smart Pavement” (Intelligent Floor) many believed it was a ridiculous idea was presented, but now there are British people, Chesham, who became the first to have wifi installed beneath its streets.
The pavement is intelligent initiative services company Virgin Media, which, with this facility, ended its pilot. The installed wifi offers a speed of 166 megabits per second, or seven times higher than the average speed in the UK, is free and covers the entire city center. What you do is install routers in the underground and the entire system is rainproof.
Now the big cities plan to have this invention.
The first smartphone holographic world
Usually the first smartphone with holograms.
Each year takes place in Las Vegas, Nevada, United States “Fair Consumer Electronics” (Consumer Electronics Show (CES) and in 2015 an invention dazzled everyone and so was the winner of the show: it is the first holographic smartphone . Is Takee 1 Technology Being Chinese company.
This smartphone can control our device “touching” holographic images that linger in the air.
It also allows viewing images, applications or videos holograms, giving a three-dimensional view (3D).
Red Star was built using Linux, a free and open source platform that can be freely modified by users and it was designed that way to make it as accessible as possible.
