Internet 5g has already begun an evolutionary step in many countries, learn how it can reach you and how online behavior will change.
Each new wireless network generation provides our smartphones with faster speeds and more functionality.
One guy brought us the very first cell phones to let us call, 3G took us online for the first time, and 4G provided the speeds we enjoyed today.
But as more users come online 4G networks have reached the limit of what they are capable of at a time when consumers need their smartphones and tablets to have even more information.
Now we’re going to the next mobile phase of 5G. It can handle a thousand times more traffic than the networks of today and it will be up to 10 times faster than 4 G LTE.
Imagine downloading an HD movie in less than a second and then letting your imagination run wild 5G will be the basis of virtual reality.
5G Internet how to install
We can’t even imagine autonomous driving the Internet of Things and stuff. But what a 5G network is exactly.
The truth is that experts are not able to tell us what 5G is because they don’t even know it yet.
But at the moment five brand new technologies are emerging as the foundation for the formation and full duplex of 5G millimeter waves of massive MIMO small cells. Technology for the first time.
On the radio frequency spectrum, no one millimeter waves your smartphone and other electronic devices in your home using very specific frequencies.
Typically those under six gigahertz. But these frequencies are starting to become more crowded.
Carriers can only rely on the same amount of radio frequency spectrum as so many bits of data as more phones come online. We will begin to see slower service and more connections dropped.
The alternative is to open some new property in order for researchers to experiment with broadcasting on shorter millimeter waves.
Those that drop between 30 and 300 gigahertz this spectrum segment has never been used for mobile devices before and opening it means more space for everyone.
But it’s a catch. Millimeter waves can not travel well through buildings or other obstacles, and to get around this problem they tend to be absorbed by plants and rain.
Today’s wireless networks rely on large high powered cell towers to transmit their signals over long distances, we will need technology number two small cell networks.
Yet note that higher frequency millimeter waves are more difficult to travel around barriers, which means you lose your signal when you step behind one.
Small cell networks would use thousands of low-power mini base stations to solve this problem.
Such base stations would be much closer to each other than conventional towers which form a kind of relay team to communicate signals around obstacles.
This would be particularly useful in cities as a user moving behind an obstacle his smartphone would automatically switch to a new base station in a better range of his device that would allow him to maintain his connection.
My MO my MO stands for multiple input multiple outputs next up technology number three massive.
The 4G base stations of today have about a dozen antenna ports that handle all cellular traffic but massive my. About 100 ports can be supported by base stations.
This may increase today’s networks ‘ capability by a factor of twenty-two or more.
My move comes with its own complications, of course, massive. Today’s cellular antennas simultaneously broadcast data in all directions and all those crossing signals caused serious interference. That is what takes us to engineering.
Forming the number four beam farming is like a traffic signaling system for cellular signals rather than transmitting in all directions.
It would allow a base station to send a specific user a focused data stream. This accuracy prevents interference and makes it much more efficient.
This means that stations can handle more incoming and outgoing data streams at once, this is how it works.
Say you’re in a building cluster and you’re trying to make a phone call, your signal is ricocheting off the surrounding buildings and criss-crossing the area with other user signals.
A massive base station from MIMO receives all these signals and keeps track of their arrival timing and direction.
It then uses algorithms for signal processing to triangulate exactly where each signal comes from and trace back to each phone the best transmission route through the air.
Sometimes it will also bounce individual data packets off buildings or other objects in different directions to stop signals from interfering with each other. The effect is a continuous flow of data sent to you alone.
That is what brings us to technology. Number five full duplex if you’ve ever used a walkie talkie, you know you’ve got to talk and listen for turns in order to communicate.
It’s kind of a drag. Today’s mobile base stations have just the same holding up a basic antenna that can either transmit or receive only one job at a time.
This is due to the principle of reciprocity, which is the tendency of radio waves to travel along the same frequency both forward and backward.
To understand this, it helps to think of a wave like a train loaded with data that the frequency on which it travels is like the train track and if there is a second train trying to travel in the opposite direction on the same track you will get some interference.
The solution up to now was to have the trains take turns or put all the trains on different tracks or frequencies.
But by working on reciprocity, you can make things much more efficient. Researchers used silicon transistors to create high-speed switches that carry these waves ‘ backward roll.
It’s kind of like a signaling system that can reroute to train momentarily in order to overtake one another.
That means on each track there’s a lot more to be done. It’s a lot quicker. Many of the kinks are still being worked out with millimeter waves forming massive MIMO small cell networks and full duplex. In fact, all of 5G is still an ongoing work.
It will probably also include other new technologies and it will be a whole other challenge to make all these systems work together.
