What is 5g ?
Here we will discuss about 5g in 5g network architecture. Each new generation of wireless networks offers faster speeds and much practicality to our smartphones. The terribly initial 2g cell phones allow us to send text messages for the first time, 3G put us online and 4g delivered the speeds we usually imagine today, however, as many users reconnect, 4G networks have reached their limits. Users need even more data speed on their mobile devices. We are now moving towards 5G, a next generation and advanced version of 4G mobile networks. It will be ready to handle a thousand times more traffic than current networks and will be up to ten times faster than 4G LTE.
Just imagine downloading associated HD movies in a second and watching even 8k 4K movies seamlessly. 5G will be the key enabler for many new services like virtual reality, gaming and internet of things services and many more.
Basically, the 5G network architecture or we can say that 5G technologies consist of 5 current technologies that rise as a base of 5g. Millimeter waves, small cells, massive MIMO, beamforming and full duplex.
Millimeter wave in 5g network architecture:
The best mm wave technology from your smartphone and the different electronic devices in your home use terribly specific frequencies in the frequency spectrum, generally those that are below six GHz, however these frequencies are starting to receive a lot of crowded operators that will only squeeze such a large amount of bits of information over an identical amount of radio frequency spectrum.
As many devices come back online, we are planning to start seeing a lower service and many native connections is to open a new property so that researchers are experimenting with transmission in shorter mm waves that fall between thirty-three hundred. Spectrum section has never been used before to mobile devices and the gap suggests that a lot of information measures for everyone, however there is a metric unit of capture that linear waves cannot travel well through different buildings or obstacles and that they tend to be absorbed by plants and rain to induce this disadvantage.
We want the technology to span two small-cell networks Today’s wireless networks consider high-powered giant cell towers transmit their signals over long distances, however please note that higher frequency millimeter waves have a longer time to go through obstacles, which implies that if you go backwards you lose your signal.
Small cell network 5g network architecture:
Small cell networks would solve that victimization downwards thousands of low power mini base stations, these base stations would be closer than the old towers forming a kind of relay equipment to transmit signals around obstacles, this can be particularly useful in cities because the user touched back associated obstacle his smartphone would mechanically switch to a new base station on a greater variety of his device, allowing him to maintain his association.
Massive MIMO in 5g network architecture:
MIMO means that today’s multiple input and multiple output 4g base stations have a couple of dozen antenna ports that handle all cellular traffic, however large MIMO base stations will support a couple of hundred ports, this could increase the capacity of today’s networks for an element of In fact, twenty-two or many large MIMOs come with their own challenges.
Beamforming in 5g network architecture:
Today’s cellular antennas transmit information in each direction directly from these crossover signals and can cause serious interference that takes us to the technological range. Four-beam beamforming is a kind of traffic signaling system for cellular signals instead of transmitting in all directions that would allow a base station to send an attention flow to a particular user, this accuracy avoids interference and it’s more inbound and outbound knowledge flow directly here, however it works, let’s say you’re in a very large group of buildings and you’re trying to create a call. Its signal bounces off nearby buildings and intersects with different user signals within the space, a large MIMO base station receives all those signals and tracks the temporal order and also the direction of their arrival, then uses signal processing algorithms to specifically triangulating where each signal returns and tracing the simplest transmission path back through the air to each phone will typically even bounce individual packets of information in different directions to different buildings or objects to stay signals from meddling with one another the result’s a coherent data stream sent solely to you which ones brings us to technology range five full duplex.
Full duplex in 5g network architecture:
If you have ever used a walkie talkie, acknowledge that speaking requires listening and speaking shifts, that is quite communication. Today’s cellular base stations have the same function; a basic antenna will only do one job at a time. Transmitting or receiving this is often thanks to a principle known as reciprocity, which is the tendency for radio waves to move back and forth on an identical frequency to capture this. It helps to consider a kind of wave of a loaded train with the knowledge of the frequency. Traveling is like the train track and if there is a second train making an attempt to travel the wrong way on an identical track, it will induce some interference until then, the response has been to take over the train stake turns or place all the trains on completely different tracks or frequencies.
