5G is basically the 5th generation of the cellular network. The cellular network industry has a global wireless standard that we used to communicate throughout the world. And this is the new generation of the network that enables as to virtually connect with everything around the world which also includes various devices, objects, and so on.

5G plans to use a technology called massive Mimo. Even though it usually causes interference, this uses something called beamforming.

With beamforming, you can direct the signal to the receiver’s direction instead of broadcasting the signal. And coupled with the higher frequency waves that 5G uses, means this technology can reach speeds that no one ever thought possible for the wireless network.

5G is without a doubt one of the biggest investments for the years to come. The technology started its breakthrough at the later stage of 2018. It not only offers a massive improvement in the Department of speed but also connects billions of devices worldwide with the perfect balance of speed, cost, and latency. 

How does 5G technology work?

Now that we know what 5G technology in 5g guide, let us also see how this works. First, let’s talk its spectrum.

Just like 4G LTE, 5G technology operates on a wide range of radio spectrum allotments but is capable of running on a wider range than current networks. The most common form of 5G being used is Sub-6, and mmWave.

Sub-6 refers to 5G that operates at a frequency below 6GHz. All carriers have some form of Sub-6 network, primarily because 4G LTE currently runs on these lower frequencies. For example, T-Mobile has its low-band 600MHz spectrum and its previously Sprint-owned 2.5GHz both in use for 5G.

Sub-6 spectrum is significant in the rollout of 5G, because of the fact that these lower-frequency radio waves can travel long distances and penetrate walls and obstacles. That means that carriers can deploy much larger networks without having to build hundreds of cells in every city.


mmWave (millimeter wave), which refers to the ultra-high-frequency radio waves, between 30Ghz and 300Ghz, that are used to supercharge 5G connections and deliver download speeds of multiple gigabits per second. Early on, Verizon relied exclusively on mmWave for its 5 G network, though the carrier has now started deploying Sub-6 networks too. While mmWave connections can deliver superfast download speeds, the high-frequency radio waves can’t travel long distances and can’t really get through obstacles — for the most part, even a window or leaves of a tree can block the connection.

That means to make a robust mmWave network, carriers need hundreds, or thousands, of small network cells in every city. Essentially, mmWave network deployment often comes down to having to build little networks around every corner of a building. So why bother? Well, mmWave can handle an incredible amount of data, and an incredible number of users simultaneously. That makes it better for densely populated cities, as well as places like stadiums and arenas.

All of the major carriers are deploying mmWave networks, but to date, those superfast connections are limited to a few downtown areas in major cities. It’s expected that mmWave networks will get more robust, but only time will tell how long that actually takes.

How fast is 5G?

how fast is 5g

  • Pinnacle data rate: 5G will offer altogether quicker data speeds. Pinnacle data rates can hit 20Gbps downlink and 10Gbps uplink per versatile base station. Psyche you, that is not the speed you’d insight with 5G (except if you have a committed connection) — it’s the speed shared by all clients on the cell, and surprisingly at that point, it’s high.
  • Real World 5G speed: While the pinnacle data rates sound pretty noteworthy, real speeds will not be something very similar. The spec calls for client download speeds of 100Mbps and transfer speeds of 50Mbps.
  • Latency: Latency, the time it takes data to go starting with one point then onto the next, ought to be at 4 milliseconds in ideal conditions, and at 1 millisecond for use cases that request the most extreme speed. Think self-driving fender bender frameworks.
Some more!
  • Efficiency: Radio interfaces ought to be energy effective when being used, and drop into low-energy mode when not being used. Preferably, a radio ought to have the option to switch into a low-energy state inside 10 milliseconds when not, at this point being used.
  • Spectral efficiency: Spectral efficiency is “the optimized utilization of spectrum or bandwidth so the most extreme measure of data can be sent with the least transmission errors.” It’s normal that 5G ought to have a somewhat improved spectral efficiency over LTE, coming in at 30bits/Hz downlink and 15 pieces/Hz uplink.
  • Mobility: With 5G, base stations should uphold development from 0 to 310 mph. This implies the base station should work across a scope of antenna developments — even on a fast train. While it’s effectively done on LTE organizations, such mobility can be a test on new mmWave organizations.
  • Connection density: as far as connection thickness, 5G ought to have the option to help a lot more connected devices than 4G LTE. The standard states 5G ought to have the option to help 1 million connected devices for each square kilometer. That is an enormous number, which considers the large number of connected devices that self discipline the Internet of Things (IoT).

The specific requirements of 5G technology 

requirements of 5g

5G is the new generation of silver network standards that has to follow some specific requirements. 

  • To start things off, the first requirement of 5G is to provide a data rate of up to 10 Gigabit per second. And this ensures around 10 to 100 times improvement in speed over the previous generation of the cellular network. 
  • The 5th generation of the network is required to have a latency of 1 millisecond. 
  • Have a 1000 times bandwidth per unit area. 
  • The availability of 5G must be more than 99.99%.
  • Must ensure 100% coverage for the user. 
  • The energy usage on equalizing the network must be reduced to 90% from the previous generation of networks. 
  • Must ensure up to 10-year battery life for various low-power IoT devices. 

Advantages of 5G over 4G 

Needless to say, the 5G ecology is far superior to 4G in various standpoints. 

advantages over 4g

Increased capability 

After the shift from 3G to 4G, we saw a massive changing speed on various mobile broadband services. The main goal of 4G was two focus on speed. But the investment in 5G is much more than that. 

The end goal of 5G is to create a more unified system and capable platform. As a result, we will be able to experience a mobile broadband service that is far superior to the previous generation. It will also ensure there are critical communication and massive IoT designs. This technology introduces a wide range of models and some of the newest ways in which we can utilize the interconnect. 

Improved spectrum 

The 5th generation of the cellular network is designing such a way that it can utilize almost every bit of the spectrum available on various law mid to high bands. This is one of the biggest improvements we see from 4G. 

Improved speed 

This one is a no-brainer. Whenever we think about what is 5G, the first thing that comes into our mind is a network with better speed. And it is perfectly true. 

5G offers a significantly faster transfer rate than 4G. We can see up to 20 Gigabit per second at big data rates and at least more than 100 megabits per second as average data transfer rates. And this improved speed alone knocks 4G out of the park. 

Improved latency

Another one of the biggest advantages we get from %G is its significantly lower latency than 4G. As a result, we get to witness some of the most instant and real-time communication systems. With an end-to-end latency of alone 1ms, the sky is the limit.

 Improved Capacity

Another big perks of the 5G are its improved capacity over its previous counterparts. With 5G, you get support for over 100 times the traffic capacity for your system.

Is 5G safe?

There are many conspiracy theories found on the internet that blames 5G for many health hazards. But are they true? Let us find out.

The 5G waves that are used throughout the world falls in the microwave band. And microwaves are known to heat objects as they pass through them. But the level of wave used for 5G is totally harmless when it comes to heating.

The radiofrequency might have a low wavelength, but the wave level is so low that it is impossible to cause any harm to health.

The power level of the 5G transmitter is even lower than the 4G technology. So the radiation exposure will be even less. So if you are wondering if 5G is safe, the answer is an absolute yes.

Economic impact of 5G

When the idea of 5G was first created, everyone knew that it is bound to have a huge impact on the world economy. And this turned out exactly how we thought it would. 

5G offered massive economic benefits throughout the world. And we can see it from the instrumented modeling analysis of 5G on the United States economy. 

In brief, 5G is estimated to offer more than 15 million jobs. The job sectors created from the advancement of the 5G bill provide all kinds of jobs including part-time, full time and various temporary project jobs. 

The estimated sales growth of the US economy can drive up to almost 2.7 trillion due to 5G. It is estimated to increase the US GDP by almost 1.5 trillion, which is even bigger than the annual GDP of more than 94 percent of the world. 

5G phones 

what is 5G phones

Unlike the previous years, the 5G phones are now becoming mainstream. You and get your hands on a 5G phone or only 500 U.S. dollars. The next goal of 5G is to utilize the C bend that AT&T and Verizon promise to turn on this year. 

Right now, the iPhone 12 series, the Samsung Galaxy is 21, the LG wing and the Google Pixel 5 have C band. 

As there is a various band of 5G, low and mid bends are comparatively much less expensive to implement on the phone. but for the case of high band 5G, it gets costlier. 

The author of the phone plays a big role in properly utilizing the 5G technology. Last year the One+ 70 pro and One+ 8 went through vigorous software updates. This made sure that the phone can offer better performance on low band 5G. 

but the great news is, companies like Huawei, oppo, realme, Xiaomi, and many others are offering 5G phones also. They are not designed to work on the 5G network that the US uses. The main target of that phone is to use the European and Asian 5G mid-band networks. 

Applications of 5G

Now that we know what is 5G , it is time to take a look at all the 5G applications in this 5g guide. This will provide us a good idea of what this game-changing technology has to offer 

Automatic vehicles

You haven’t heard it already, automatic vehicles are one of the most impressive applications of 5G technology.  We all know that automatic vehicles at the future. And he’s going through its breakthrough. The reason why automatic vehicles are not mainstream yet is due to the barrier it faces. And 5G is here to make all these barriers and turn this vision into a reality.

With 5G, an autonomous vehicle will be utilizing a network with massively decreased latency. As a result, vehicles will be able to respond to changes almost 100 times faster than ever.

For an automatic vehicle, it needs to automatically respond to various changes and objects instantaneously. It has to accomplish instantaneous receiving and sending off information in milliseconds who effectively shift or break the car with purpose. This may include various types of information like roadsigns, the car in front, people, hazards, etc. 

For instance, if a car is moving with a speed of 50 kilometers per hour, with 4G technology, it will be able to avoid crashes and break automatically at a distance of 4 feet distance. But with 5G the minimum traveling distance while breaking will go down to almost 4 inches. and this could be the difference between life and death. 

Industrial automation 

One of the other main applications of the 5G network is industrial automation. With automation in the industry, you will need less manpower, have increased wireless flexibility, and can reduce the cost of application by a significant amount. The industrial automation that we can see today mainly uses cable networks. 

The Wi-Fi network does not provide enough control and mobility with a range to be used in industrial automation. With 5G you will be able to go fully wireless and run smart factories much more efficiently. 

With the integration of 5G, we’ll be able to see an industry where people and robots can work together and be in constant communication. This human-machine partnership will shift the industry to a much more efficient and futuristic path that we need.

Augmented reality

One of the most exciting and crucial aspects of 5G is its effect on the Internet of Things. While we currently have sensors that can communicate with each other, they tend to require a lot of resources and are quickly depleting 4G data capacity.

With this kind of technology, speeds and dramatically higher capacity limits, the IoT will be powered by communications among sensors and smart devices (here’s MTC again). Compared to current smart devices on the market, MTC devices will require fewer resources, since huge numbers of these devices can connect to a single base station, making them much more efficient.

Final thoughts

From enhanced mobile broadband, massive IoT applications two critical communication systems, 5G is here to make a strong statement. 

Now that you know what is 5G, he will also be glad to know that this is already here. Various global operators have already launched 5G networks for commercial use. Over 70 countries worldwide have already diploid such networks. 

So here’s to a new era of communication technology. Soon enough we will be able to see 5G everywhere. And it promises to change the way we see our life and work. Hope this brief 5g guide helped you with a great exposure of knowledge !
