How to get the best Wi-Fi signal in your house

It’s hard to underestimate how fundamental Wi-Fi is to so many of us these days. Whether we’re watching movies on Netflix, streaming music on Spotify, or downloading every science paper on the web for free, that signal in your home is what keeps us connected to the all-knowing, all-seeing Internet. Yeah, there’s mobile data too, but it can’t compete with home broadband for value when it comes to heavy, ongoing data consumption.

Which is why it’s kind of funny that so many of us take for granted where we place our Wi-Fi router in our homes. After all, you’re paying for that fast data connection to travel a pretty significant distance to your house or apartment, so it’s silly to throw the maximal quality and speed of the signal away because you unwittingly chucked your little digibox in an inopportune location after unboxing it.

It might be common sense to some, but as April Glaser writes at Wired, it’s helpful to think of your Wi-Fi router’s signal strength in terms of its radius of broadcast. That signal extends out in every direction from the router, meaning you should ideally place the device in a central location in your home. Otherwise, if you store it up one end of your pad, you’re really just handing over your quality coverage area to your neighbour, your garden, or the street out front.

Of course, depending on your home and where the phone/data ports in your house are located, that could be easier said than done. The solution then is to consider running some Ethernet cable – which you can buy in some pretty crazy-long lengths – to your router, letting you place it pretty much anywhere in your home you want. (It’s worth noting that connecting your PC or Mac to your router directly via Ethernet will also ensure a faster connection than what Wi-Fi allows.)

As Wired points out, the same principle applies to multiple storeys. If you can place the router as close to the vertical middle of your home, that could improve the signal’s reach overall.

Another thing to bear in mind is walls. Any solid structure can impede Wi-Fi signals, and while the technology can impressively permeate things like walls some of the time, they’ll still have an impact on the signal.

Because of this, place your router in as open a location as possible, away from brick or concrete walls if you can – and similarly avoid the floor, which will block in part any Wi-Fi waves directed downwards.

As we’ve mentioned before, other electronics in your home can interfere with the frequency of your Wi-Fi too, so try to keep your router away from things like TVs, microwaves, cordless phones, and any other kinds of devices that broadcast wireless signals as part of their regular operation.

Don’t forget about your router’s antenna either. Not all router models include an external antenna you can manipulate, but if yours does have one – by all means, manipulate it! Seriously, the angle and direction of your router’s antenna will have an impact on the way it broadcasts radio waves, and it could make a noticeable difference in your home.

Which brings us to our last point. When you’re playing around with Wi-Fi, it’s a good idea to bring a little scientific measurement into the equation. There are plenty of apps and websites that help you measure the download and upload speed of the device you’re currently using, so when you’re trying a new router placement or configuration, take the time to prove to yourself that your new setup is better than your old one – for at least the locations in your house where you’ll most often be needing good data speeds. Good luck!

Here you can get a better Wifi router if you need one.

Internet at speeds of 1Gbps by use of LED bulbs

Imagine a technology, which could connect you to the Internet at speeds of 1Gbps, by simply using LED bulbs, free from any waves with potentially harmful effects on the body.

That is precisely what Li-Fi offers. It is a technology in the development phase and is planned to be used first in businesses and then in homes.

Li-Fi, which stands for Light Fidelity, is a wireless communication technology based on the use of the light spectrum.

It sends data by switching the current to LEDs off and on at a very high rate, and is invisible to the human eye.

Safe technology

Li-Fi has many advantages, starting with the absence of radio waves, which could be harmful to health in the long term, and electromagnetic interference.

Also, the Li-Fi spectrum is around 10,000 larger than Wi-Fi’s, making it possible to connect more users together at the same time.

Furthermore, as light cannot pass through walls, there can be no automatic connection from one room to another. But it also means that piracy from outside sources becomes impossible.

In terms of speed, Li-Fi looks highly promising. It could theoretically achieve speeds of 1Gbps, which is faster than the most recent Wi-Fi standard (802.11ac).

Researchers at Oxford University in the UK have achieved speeds of 224Gbps in the lab, which is a record, but it is not likely to become the norm in homes.

In France, several Li-Fi connection experiments are currently underway, mainly in business settings led by specialist companies such as Oledcomm and Lucibel. Velmenni, an Estonian start-up, has already carried out tests in homes.

One of the preconditions for Li-Fi to become commonplace is for the whole environment (companies, public places, housing, etc.) to be equipped with LEDs and for mobile phones to have light sensors compatible with this new technology.

A camera has successfully been powered using spare Wi-Fi signals

Researchers in the US have tweaked a regular Wi-Fi router and made it capable of continuously powering a battery-free surveillance camera. Even better, their work didn’t interfere with the router’s data transfer speeds.

The breakthrough could help researchers overcome one of the main challenges when it comes to the development of new technology – including the Internet of Things, which aims to put a chip inside all our household appliances and bring them online: how do we keep everything powered up without lots of cords?

Researchers have long known that the electromagnetic waves broadcast by Wi-Fi routers could be harnessed for energy as well as sending information, but the challenge was finding a way to do this reliably and continuously. A team from the University of Washington in the US has now accomplished this by simply changing the way a router broadcasts. They’re calling their new approach ‘power over Wi-Fi’ or PoWi-Fi.

“The ability to deliver power wirelessly to a wide range of autonomous devices and sensors is hugely significant,” writes MIT’s Technology Review. “PoWi-Fi could be the enabling technology that finally brings the Internet of Things to life.”

In the past, scientists have never been able to harness enough Wi-Fi signals to power anything of much use. But the team’s big break came when they attached a simple antenna to a temperature sensor in order to see how much power they could get from a nearby router.

They found that the resulting voltages produced by the Wi-Fi signals were never high enough to cross the operating threshold of around 300 millivolts. But they often came close.

The problem, they realised, was that Wi-Fi routers don’t continuously blast out electromagnetic waves, they send them out on a single channel in bursts. But by programming a router to broadcast noise across a range of Wi-Fi channels even when it wasn’t transmitting information, they were able to pump out enough signals that their antenna could then use to provide continuous power to electronic devices.

Using their prototype, the team managed to show for the first time that they could not only run battery-free temperature and camera sensors using Wi-Fi signals from a distance of six and five metres respectively, they also proved that they could charge a range of coin-cell batteries at distances of up to nine metres.

They then took their system into six metropolitan homes to show that the set-up worked in real life, and didn’t interfere with data transfer speeds. The results are published over at

The question that needs to be answered now is how these routers interfere with other signals in the area. “Having a router next door that is blasting out signals on three Wi-Fi channels might not be everybody’s idea of neighbourly behaviour,” writes MIT’s Technology Review. “It is worth pointing out, however, that if this kind of interference turns out to be a problem for current routers, it is one that could be solved in future generations.”

The next step is further testing on these routers under a range of different conditions to make sure they really can help to provide us with regular power for our devices while we browse the Internet. And if that’s the case, then it could seriously change the way we power up our homes. We can’t wait.

A Glimpse into the Future: What to Expect from Smartphones in the Next 10 Years

Believe it or not, smartphones are rapidly approaching their 20th birthday, and they have certainly changed since their inception. Between their video streaming capabilities and their effectiveness in hosting a variety of  iPhone app award winning programs, smartphones allow their users to do virtually anything while out and about. Still, there is room for improvement, and the future certainly looks promising. Although it is hard to know for sure what developers have up their sleeves, the following features could be available the next time you are ready to upgrade your phone.

Bendable screens

Although the latest smartphones currently boast a fairly large screen, most users would agree that if they want to watch a movie or play a video game, they would prefer to do so on their television. However, that could all change with bendable screens; Organic Light-Emitting Diode technology is just around the corner, and it will allow screens to be super-sized in comparison to today’s smartphone models. In addition, this technology will open the door to a number of other inventions, some of which are already being researched. For example, Nokia is working on a smartphone that can either be worn like a watch or used in a more traditional manner, depending on the user’s preferences.

Tiny projectors

Just over two years ago, the Samsung Galaxy Beam came onto the market boasting a Digital Light Projection WVGA projector. What good is a smartphone with this capability? Well, there is a possibility that the device will be able to double as a gaming console. Users will simply need to project their game onto a flat wall or other compatible surface and use their voice or their body as a controller. The biggest problem with this idea, though, is that it would be very taxing on your smartphone’s battery. In addition, the projector would have to be small, which means that it might not be able to project the necessary amount of light to get a clear picture. However, it is certainly a possibility for the future.

Better voice control

Siri changed the way that users look at their smartphone. Although voice control wasn’t necessarily a new feature, it didn’t work very well when it simply utilized sound waves to determine a command. Instead, Siri takes both syntax and diction into account, paving the way for a seamless voice control feature in the future. That’s exciting, because it will encourage users to interact with their smartphone in increasingly complex ways.

The future of the smartphone certainly looks bright. It may come at a cost, however; a device packed with the features mentioned above definitely won’t be cheap. In addition, these features could make users even more attached to their smartphones than they are now, which isn’t necessarily a good thing. Still, the benefits seem to outweigh the costs, and the developments in the industry are definitely exciting.

New Charger For All Mobile Devices In A Bag Called Phorce


Phorce is a new bag that can be used as a charger for your Smartphones and MacBooks. Phorce is the new bag that can be transferred from a backpack to a briefcase and you can stop worrying about losing it.


Never again run out of power while on the go, lose your bag, or carry multiple bags to store all of your gadgets. Phorce is the world’s first smart bag that powers all your devices (including MacBooks), connects to your smartphone via Bluetooth, transforms from a backpack to a messenger or a briefcase, and prevents you from losing it. This triple-threat smart bag will be launched through a Kickstarter campaign this week.


The bag, was constructed using the latest in technology and design, was the brainchild of entrepreneur Marijn Berk, a Kauffman Foundation scholar whose previous venture created an affordable solar-charging solution for the developing world, and James Jeffrey, a designer with more than 10 years of experience in the bag industry. They aim to raise $150,000 through their Kickstarter project so that Phorce can be released internationally.


Phorce is designed for those who’ve experienced great difficulty carrying tech equipment and staying connected while traveling extensively in the air and on the ground.


Additionally, the bag comes with an Android and iOS application that allows you to talk to your bag by connecting your phone to your Phorce bag via Bluetooth. This app lets you gauge the power that’s left in your device through an intuitive graphics display on your screen that also shows you the exact number of remaining charges for all your devices. Additionally, this feature sends a notification to your phone if you leave your bag behind, so you can quickly run back to grab it.


Whether you’re at a meeting and need a briefcase, carry heavy items and need a backpack, or need your hands free to bike to work, Phorce can transform from a messenger bag, to a backpack, to a briefcase in a matter of seconds, with no additional equipment needed. At the airport, the Phorce bag has a special opening that allows it to slide over the telescopic handles of your trolley bag, making it easy to get to the gate on time. The bag is compact and light-weight but can transform into a bigger bag, thanks to its expansion zipper that gives you 240 cubic inches of extra space.


The bag includes protective padding, a custom-made water-resistant fabric, and waterproof zippers to protect your gear from shocks, drop and rain. A special fabric inside the pockets helps clean your devices for fingerprint-free displays.

New Technology Can Improve The Connections Of Public WiFi By 700%

Researchers at North Carolina State University have reached a new software that can solve the problem of crowded Internet connections in the public places.

The new software can be added to existing network setups, the researchers said. Existing systems work by transferring data through a single channel. But they can become clogged when too many requests are sent by users all attempting to access the WiFi network at once.

They can attempt to prioritise data to be sent back to users – which are needed in order to display services such as websites – but that, in turn, slows down new requests by other users, often meaning that pages become slow or even impossible to load.

But the programme developed by the researchers at North Carolina State University solves that by monitoring the amount of traffic passing through a WiFi connection and sorting and prioritising it where a backlog is detected. In doing so, the software – called WiFox – smooths the flow back and forth of traffic, speeding up the connection for more people.

The research team said they used a real WiFi system capable of handling 45 users to test the system. They found that the more users on it, the more the new program improved data throughput performance. Improvements ranged from 400 per cent with approximately 25 users to 700 per cent when there were around 45 users.

This translates to the WiFi system being able to respond to user requests an average of four times faster than a WiFi network that does not use WiFox.

Their paper, “WiFox: Scaling WiFi Performance for Large Audience Environments,” will be presented at a conference in Nice on December 10. The paper was co-authored by Jeongki Min, a Ph.D. student at NC State, and Dr. Injong Rhee, a professor of computer science at NC State. The research was supported by the National Science Foundation.

AEG Is The Possible Building Blocks Of Earth Primary Genetic Material

Scientists from USA and Sweden reached for a new discovery proving that the AEG is probely the building block of the primary genetic material even prior to the DNA. The team reached that AEG in cyanobacteria which are one of the most primitive organisms on earth.

The answer may be AEG, a small molecule that when linked into chains forms a hypothetical backbone for peptide nucleic acids, which have been hypothesized as the first genetic molecules. Synthetic AEG has been studied by the pharmaceutical industry as a possible gene silencer to stop or slow certain genetic diseases. The only problem with the theory is that up to now, AEG has been unknown in nature.

A team of scientists from the United States and Sweden announced that they have discovered AEG within cyanobacteria which are believed to be some of the most primitive organisms on Earth. Cyanobacteria sometimes appear as mats or scums on the surface of reservoirs and lakes during hot summer months. Their tolerance for extreme habitats is remarkable, ranging from the hot springs of Yellowstone to the tundra of the Arctic.

To determine how widespread AEG production is among cyanobacteria, the scientists analyzed pristine cyanobacterial cultures from the Pasteur Culture Collection of Paris, France. They also collected samples of cyanobacteria from Guam, Japan, Qatar, as well as in the Gobi desert of Mongolia, the latter sample being collected by famed Wyoming naturalist Derek Craighead. All were found to produce AEG.
Professor Leopold Ilag and his student Liying Jiang at Stockholm University’s Department of Analytical Chemistry analyzed the same samples and came up with identical results: cyanobacteria produce AEG. While the analysis is certain, its significance for studies of the earliest forms of life on Earth remains unclear.


Why Holoscreen Technology Will Lead Us into the Future of TV Displays

What Is Holoscreen Technology?

The holoscreen is a distinction of a technology known as holoprojection technology. The purpose of this technology is to display holo-signals. However, rather than projecting an image with three dimensions, holoscreen technology represents a usual screen in the format providing images in two dimensions. It has the exception of space and weight because it supports flat and solid screens. You can attach this screen to the wall of your room.

What Is So Special About Holoscreen Technology?

Holoscreen technology provides tech-savvy users with a new dimension in TV screens. For instance, if you want to watch your favorite movie on a flat screen, then nothing can beat the experience provided by holoscreen televisions.If you are looking for a deal, you can get all of Dish’s Spanish channels from Latino Satelite’s Latino Max deal.

Though it is quite difficult to believe, many observers are of the opinion that holoscreen technology will lead its users into the future of TV displays. In fact, professionals in the same field are showing their interests and passion to work further to offer holoscreen technology to the public in the near future. For this reason, engineers and researchers have already made plans to work on this emerging technology.

When it comes to proving the potential of holoscreen technology as the future leader in TV displays, professionals have already come up with different examples. Their work mainly shows the efforts in technology and innovation shows.

Claro is a TV show that has shown this latest innovation to people. Of course, it seemed to be impossible at first because it is hard to believe this at first sight. This is why the technology depicts an entirely new dimension of innovation. Claro amazed viewers by using a thin glass pane. Here, it used a projector at its right angle so that there is no way for light to enter, leading to show a clear picture.

When viewers saw the clear picture, they were speechless because the quality of this technology applied in TV displays was simply outstanding. This gives a futuristic look to anybody who sees it for the first time. If you are looking for different channels while watching TV, then you can get all of Dish’s Spanish channels from Latino Satelite’s Latino Max deal.

There are a variety of holographic displays. Among many, one such type of holographic displays is Chooptics360. This type is quite close to that of 3D Holographic imaging. You can see this technology from any angle without compromising on clarity. Regardless of choosing angles, you can view it from any side and still find its picture quality perfect.

If you want to know the effectiveness of holographic TV displays, then an ideal way to do this is to view it from all angles. Once you do, you will not notice a single distraction in the picture quality as you can see the picture from all sides. However, LED televisions still need to improve their viewing angles. This indicates that it has been a great improvement for TV displays using holoscreen technology.

Usually, people look for latest technologies when they go for purchasing a television. Since the holoscreen technology promises to grab the attention of many, it is expected to be preferred by a lot of people. This is because watching TV shows and movies from a holoscreen TV display provides an entirely different experience to multiple viewers. Obviously, you cannot get the same experience from your traditional TV.

It is important to know that holoscreen technology is not limited to TV displays only. Due to the extended utility of this technology, there are other areas too which require the use of this technology. Besides the electronics industry, other industries that can benefit from holoscreen technology are military, computer gaming, or medical.

When it comes to playing computer games though holoscreen technology, you will experience a different way of interaction as you do with your computer. If it is about playing online games, you can have so with more fun by choosing the 3D style of holoscreen technology. Though the computing world is vast, holoscreen technology can align well to this in the near future.

Although different people have positive opinions about the holoscreen technology, we cannot know what will happen in the future in terms of its usage. However, the current scenario shows that you should expect more from it in the future. In addition, developers and engineers seem to be passionate about increasing its presence in TV displays in the future.

Nano Technology

Carbon nanotubesNanotechnology may be able to create many new materials and devices with several applications in energy production, medicine,  organic materials and electronics.

Recently there has been many applications using nanotechnology also known as nanotech.

Carbon nanotubes, graphene and their compounds presents electrical properties for organic materials, and electronic applications such as photovoltaics, sensors, semiconductor devices, displays, conductors, smart textiles and energy conversion devices (e.g., fuel cells, harvesters and batteries).

Applications of Carbon Nanotubes and Graphene for electronics applications

Depending on their chemical structure, carbon nanotubes (CNTs) can be used as an alternative to organic or inorganic semiconductors as well as conductors. In addition to their high conductance, they can be transparent, flexible and even stretchable. Here, applications are for displays, replacing ITO; touch screens, photovoltaics and display bus bars and beyond. CNTs will be able to provide high performing devices which can ultimately be made in low cost manufacturing processes such as printing, over large areas. They have application to supercapacitors, which bridge the gap between batteries and capacitors, leveraging the energy density of batteries with the power density of capacitors and transistors.

Graphene, a cheap organic material, is to be used in some applications as a significantly cheaper printed conductor compared to silver ink. Graphene and its compounds are increasingly used to make transistors that show extremely good performance.

Nanofibers that could be used to manufacture clothing and textiles.

With their latest invention engineers will be able to make clothing that could power different portable devices. It is worth mentioning that thanks to nano-sized generators with piezoelectric properties the nanofibers have the ability to transform energy from mechanical stresses, stretches and twists into power. Thus, if used in clothing, the nanofibers could make use of body movements to power gadgets.

Nano-nose to help identify illnesses
Nanoparticles are used by U.S. researchers to ‘smell’ the scent of illnesses in fluids of the body. The researchers used nanoparticles of gold with different coatings to distinguish among different proteins and detect the illness, as reported by the New Scientist.

The ‘nano nose’ uses a system of six receptors, each one consisting of a solution with gold nano particles not larger than 2 nanometers, each one having a different coating too. Nitrogen atoms form the organic molecules which make up the coating of the nanoparticles.

A “nano-needle” with a tip about one-thousandth the size of a human hair, pokes a living cell causing it to quiver briefly. Once it is withdrawn from the cell, this ORNL nanosensor detects signs of early DNA damage that can lead to cancer.
