Even if you have some knowledge about computers and technology in general, wireless routers can still be a mystery. OK, we all know what Wi-Fi means, but in most cases, other terms like Parental controls, Guest networks, UPnP, and similar are unknown for most of us. Well, we are here to help and make some things clearer for those buying a new wireless router.
This article will guide you through the necessary things you need to pay attention to when buying a new wireless router. In the end, you should be able to choose the best one, which will provide an excellent Internet experience.
When it comes to wireless routers, we can say that they have different signal ranges. When the signal is strong and you are in the covered area, you will be able to enjoy the best browsing speeds. On the other hand, if the signal is weak because you are not in the optimal range, you can expect slow speeds, problems when connecting to the wireless network, and so on.
This can be pretty annoying. Having problems with the signal strength because of short-range can be prevented if you do some measuring first. In order to determine the preferred signal range, it is best to position yourself at the center of the place you are going to use the router in and measure the distance to the furthest position you are going to need a signal.
Generally speaking, this is the required signal range, but the signal range mentioned on the router is not always correct. For that reason, it is always better to get a router with a higher signal range. 20-40% more is usually enough.
Depending on the internet activity, your router will be more or less stressed. To be more precise, it is not the same whether you are playing Fortnite online or just reading through some recipes or checking your Facebook account. During your research for the best router, one of the terms you will hear quite often is “band”.
There are single and dual-band routers, and since we are looking for the best router, we should opt for the dual one. Of course, this doesn’t mean that the single band router won’t work well; it’s just that dual-band routers are better when it comes to online gaming, streaming movies, listening to your favorite songs using Spotify, and so on.
Just like with smartphones, the price of the router increases with some additional features. The thing is that maybe you will easily find a way to use a specific feature in a more affordable wireless router. Still, on the other hand, if you pay for a high-priced router and you don’t really need that feature, you are practically wasting money. This is why you need to think about what you really need from your wireless router.
Do you need to set up a guest network or control the time your kids spend online? If yes, then it is good to pay for these features since they are easily accessible when you log in to the wireless router. However, if you are just interested in Netflix and Facebook, you will be more than satisfied with a cheaper router without these features.
It would be nice to get all the features we need, but in most cases, our budget is the biggest obstacle here. A pretty good wireless router can cost around $150, and in most cases, even more. Since we know how many devices depend on our internet connection, we can say that the router is a pretty important device in any household. However, you shouldn’t think that a more expensive router will make your Internet speed faster. Therefore, just stay with the features you need the most and don’t go crazy.
Quick Summary – How To Choose The Best Wireless Router
- Measure the distance for the best signal range and increase it by 20 to 40%
- Depending on your internet usage, choose a single band or dual-band router.
- Find the router that has all the features you really need
- Choose a router that fits your budget but doesn’t be afraid to spend some extra cash for something you are going to use for a long time in the future.
As you can see, it is not that difficult to find the best wireless router for you. However, before purchase, we strongly recommend you check some customer reviews. By doing this, you can easily see whether there are some specific problems with the router you are planning to buy. Good luck!
Scientists fold the Smallest Microchips ever from Graphene
New developments from physicists from the University of Sussex could lead to faster electronic gadgets. The physicists have created tiny microchip-like objects using ‘nano-origami.’ They foresee phones as well as computers operating many thousand times faster.
The researchers worked with 2D materials, including graphene. They used structural defects within the materials to build the microchips.
These defects affect the properties of the materials, both nano-mechanical and electronic.
The researchers pinpointed the effects of defects like grain boundaries, collapsed wrinkles, and folded wrinkles using Raman mapping and atomic force microscopy.
Graphene acts as a transistor when some distortions are folded into graphene. Transistors are the basic ingredient of electronics. When a graphene strip is folded like that it acts like a microchip.
The graphene strip in question is around 100 times tinier than normal microchips.
Lead researcher Dr. Manoj Tripathi explains the mechanism: “Instead of having to add foreign materials into a device, we’ve shown we can create structures from graphene and other 2D materials simply by adding deliberate kinks into the structure. By making this sort of corrugation we can create a smart electronic component like a transistor or a logic gate.”
The technique relies on Moore’s Law, a law which stipulates that the total sum of transistors within an integrated circuit doubles every two years.
Academics and leaders in the industry have warned that Moore’s law may not necessarily apply for transistors similar in size to silicon chips.
Graphene is a material that provides a possible alternative to silicon and can help to conserve Moore’s law. The researchers are the first to create a microchip using folded graphene.
Said Professor Alan Dalton: “We’re mechanically creating kinks in a layer of graphene. It’s a bit like nano-origami. Using these nanomaterials will make our computer chips smaller and faster. It is absolutely critical that this happens as computer manufacturers are now at the limit of what they can do with traditional semiconducting technology. Ultimately, this will make our computers and phones thousands of times faster in the future.”
“This kind of technology – ‘straintronics’ using nanomaterials as opposed to electronics – allows space for more chips inside any device. Everything we want to do with computers, to speed them up, can be done by crinkling graphene like this.”
Now the researchers are hopeful for further developments in sustainable technology because this process does not require additional materials and can go on at room temperature. It saves energy.
AMD Acquires Xilinx for $35 Billion
AMD has finally confirmed that this week it will be acquiring FPGA maker Xilinx for $35 billion. Xilinx makes FPGA or Field Programmable Gate Array chips. Rumor had it that AMD was buying Xilinx for $30 billion.
FPGA chips can be reconfigured for a wide variety of specialized tasks. These chips are in high demand within the automotive industry, cellular base stations, and other vertical markets. They are programmed to carry out specific tasks.
To analysts, the move means that AMD is boosting its Artificial Intelligence capability to keep up with competitor Nvidia in working with Machine Learning as well as Inference.
According to Semico Research, Xilinx’ Machine Learning and Artificial Intelligence capabilities will be a boost for AMD as it moves into AI and ML.
AMD will be in a position to diversify and penetrate new markets that they are yet to get into and which would require massive investments. These are markets like Telcom, Industrial, and Automotive.
Both AMD and Xilinks had invested heavily in their data centers, and the new acquisition means that AMD is in a better position to compete with Nvidia.
The deal reflects the steady growth of AMD stock from $2 five years ago to $78.88. The company is worth $100 billion.
In going for an all-stock deal, the company has avoided taking on debt which can potentially harm the company.
AMDA is following the example of Intel which acquired Altera in 2015 for $16.7 billion. Altera was the top competitor for Xilinx before the acquisition; which did not turn out well for Intel, due to leadership issues.
The coming together of Xilinx and AMDA is a unification of two companies that can easily complement each other’s strong points.
The deal is the fruition of years of talks between the two companies. The Xilinx leader will remain on board after the merger.
Self-Erasing Chips could Enhance Security and Curb Counterfeits
Scientists from the University of Michigan are experimenting with self-erasing chips that make it easier to tell when an electronic device has been tampered with.
The self-erasing chips are capable of sending alerts whenever someone tampers with a sensitive shipment.
The chips were built with a new material that temporarily stores up energy reserves and emits a different color of light as it does so. The chip will erase itself within days using blue light.
At the moment, it is difficult to tell whether counterfeiters have tampered with an electronic device. The device may still operate normally but will be providing a third party with information, according to Assistant Professor Parag Deotare.
A self-erasing bar code on the chip will enable the owner to know when someone opens it and installs a listening device, for example. Bar codes on circuit boards and integrated circuit chips can provide evidence that the items were not tampered with in transit.
The bar codes can also be built to last longer so that they are written into the device for example as software authorization keys.
Researchers laid a three atom-thick semiconductor on a layer of molecules on azobenzenes which shrinks when it comes into contact with Ultra Violet light. These molecules will in turn pull on the semiconductor so that it emits light in longer wavelengths.
You can only read the message when you are looking at it under a specific kind of light. Researchers are also interested in this material as a medium for transmitting secret messages. The message will self-destruct after a while, but it can also be illuminated with blue light which will erase it.
Upon stretching, azobenzene gradually dissipates its stored energy over 7 days as long as it remains in the dark. When exposed to light, this period becomes shorter, and the erased chip can be used to record a different bar code or message.
The semiconductor is very much like nanomaterial but it can emit light in specific frequencies.
Jinsang Kim, a professor of material science and engineering designed the material together with Da Seul Yang, a doctoral student of macromolecular science and engineering. They coated it with the molecules by floating a layer of Nano molecules in water and dropping a silicon wafer into the water so that it comes out coated with the molecules.
Next, the researchers will be working to create a similar material that preserves the message intact for longer than a week and this will improve its use for anti-counterfeit measures.
The Air Force Office of Scientific Research is funding the research, and the University of Michigan is pursuing patents and commercial partners to take this technology to the market.
