5G is a fifth generation of cellular network and is going to be a successor of 4G that enabled LTE technology with its blazingly fast internet speeds. But why do we need next generation if 4G sufficiently fills the needs of personal users? You see, with the rapid growth of IoT (the Internet of Things) and increasing digitalization of our world, the current infrastructure doesn’t keep up with exponentially growing inter-device communication and right now suffers from vast technical constraints. 5G is going to be a solution to this problem. It will allow to manage almost thousand times more traffic than 4G and at the same time will be almost ten times faster. However, the implementation of such technology is by no means a trivial task, to fulfill the promises researchers must first overcome many issues and meet with technical requirements. Fortunately over the last 2 years we’ve managed to resolve most of these problems and it is expected that 5G will come in late 2020.
So what lies behind the technology of 5G?
Millimeter waves – Currently all electronic devices use electromagnetic waves between 3kHz and 6GHz. However this frequency spectrum is getting filled up pretty quickly with the sheer amount of transmitted data. That is why 5G wants to widen its bandwidth up to 300GHz. Unfortunately, higher frequencies have smaller effective distance as are easily absorbed and cannot penetrate building walls.
Small Cells – are small radio access nodes that help to provide network service to end users. Their range is between 10 meters to 2 kilometers and they are meant to increase network access in densely populated urban areas that cannot be sustained by microcells alone. With many of these devices installed in towns and buildings they will resolve the problem of millimeter wave inefficiencies.
Massive MIMO –(Multiple Input Multiple Output) is an enhancement of current MIMO technology, that conventionally uses two transmit and receive antennas to operate network communication. With this upgrade transmitters will significantly improve throughput, network capacity and coverage.
Beamforming – Will allow devices to stream data directly towards a recipient. This will prevent wave interference and make data communication way more efficient, thus allowing the transmission station to handle more devices at once.
Full Duplex – Radio transmitters cannot receive and send data on the same frequency because of wave interference. This results in doubling amount of used up bandwidth for a single connection. To solve this problem researchers came up with special device that allows to intelligently coordinate transmission and reception of data on the same frequency.
Questions:
1. Is 4G LTE enough for your personal needs, do you need almost 10x faster 5G internet speed?
2. How do you think the world will change with the increase of IoT devices?
3. Have you ever heard about 5G or maybe been involved in a project with that technology?

I believe it will change slowly like it does now. IoT allows to automate many simple repetitive tasks that are usually done by people. I think everyone can image a warehouse managed by many devices and robot instead of people.
I've read about it, but for me it's just an upgrade so I'm not interested in it especially.
IoT solves many current world problems and makes our life much easier. In my humble opinion, it's much more profitable than AI.
I heard about 5G technology. I also heard about many protests around it. This topic induces mixed feelings. I completely disagree with those who want to prohibit it. I love to see how fast technology is developing.
When it comes to IoT I think it might change the future and help many people with everyday tasks. It will take few years from now but I think it is the future of the world and will be common in a few years.
I have heard about 5G from someone but I didn't read anything more about it. As every new technology there are some people who thinks it will help in a future and others who think it will be problematic and will lead to some problems in the future.
I think that the future concerning IoT devices is really interesting and some of those new technologies could become very useful, but it means that we are getting more and more dependent on technology which could be dangerous in some cases.
I've heard about 5G, but I wasn't familiar with all those details mentioned by you.
I think the world will change in many ways and IoT will help people in everyday tasks, help to save time and energy by doing things for them. Im excited to see how it will develop in the future.
I have heard about 5G and I have read an article or two about it but I never was that interested in this topic to go deeper and gather more information
IoT will change everything: smart technologies will bring business savings, security and innovation.
The great demand for the Internet, it is constantly growing, the increase in coverage, as well as the speed of data transmission will affect the bandwidth. Today, a lot of equipment is being tested to ensure users have a stable Internet experience.
Actually, I have no idea how the world will change but I hope life will become easier and more pleasant.
Yes, I have heard about 5G lots of times and that Japan was the first country that started using this cellular network but can’t say nothing more about this topic.
Personally, I am not interested in wireless network or IoT, so I am not aware of any new projects in this field.
Certainly, improving the quality and speed of the link will allow better implementation of IoT devices, but I do not think that 5G will revolutionize this area.
I've heard about this technology before, but I did not implement any project related to it.
Unfortunately, I have not heard about 5G, but in my opinion if something should be improved, I am in favor and support this.
and as for IoT I did not delve into the IoT device, but I think that the world evolves so quickly that it will be needed and people will make the most of it, and maybe even in the future.
2. I think most processes will be automated, accelerated. You should not expect big changes, because at the moment it’s more like DIY entertainment than full-fledged products that can drastically change the world.
3. Of course, I heard about it, but I did not participate in any projects using this technology. Nowadays more people learn about 5G. It is no secret that at this moment several countries make tests of a new generation of communication.
I think that the world will probably change for better with an increase of IoT devices because our life will be much easier with it. It will help us with our daily tasks and much more things that maybe We are unaware of now.
Neither I have never heard about 5G (until now) nor have been involved in a project with that technology.
LTE is pretty fast, but phone is quickly discharged and because of it I use 3G. For my everyday needs it’s enough.
After increase of IoT device will be fewer fires related to the fact that somebody forgot turn of some device. Also will decrease number of thefts in flats or houses, because I think that in future your smart home will understand who is in apartment and call to police in it’s unknown person.
But on the other hand IoT device not such secure as they must be. For example botnet Mirai. It’s a botnet which infect IoT device and make the biggest DDOS attack at the world. It infect devices because users don’t change standard passwords and Mirai easily hack it.
I’ve already heard about 5G and I think it’s great step to digital future.
In my opinion increment of IoT devices will be profitable for all. These devices will do many things for us and solve problem so that we wouldn't have to worry as much.
One disadvantage in my opinion could be our safety. If we are surrounded by so many intelligent things we will be more vulnerable to hacks.
I've heard before about 5G a little bit, but I wasn't curious enough to check more information or get involved with any project related to it.
2. It will definitely improve our life and it will make it easier. Of course, our privacy will be dead but I am fine with that as long as my fridge knows when I should order grocery shopping.
3. I have heard about the 5G for the first time in the following video: https://tiny.pl/gz6b1. It was not the best source of knowledge about this topic, but it was pretty funny.
As for IoT, I'm worried about privacy - it's already very difficult to protect your personal information, and I fear than the advent of IoT devices will only make that more difficult.
2. I think it will change the use of IoT devices scientifically. Not as cause of it but being part of its evolution. For me the most important will be improvements in communication between autonomous cars. It is great path for that technology that can improve everyone comfort and safety
3. I’ve read about it on some medium article. Never been involved on any project but I would try if I had more time, maybe after college
With rise of IoT devices we will more and more adapt Japan like , South Korea like internet standards where most of the time internet itself is free but providers ear their money by seizing the opportunity of having more users.
5G was a mystery to me before this article, mostly because there are no sensible data plans in Poland and there wont be anytime soon .
IMO 5G will bring a lot of changes to IoT devices. Improvement in communication between every devices will force us to go further into it. Every day technology is evolving and we need to evolve with it. I believe big changes in every part of our life is coming with changes in technology.
About 5G I heard few times and also read a bit. I've never beed involved on an project, but who knows, maybe soon?
There is going to be a new type of hackers who will make your fridge lock itself if you open wrong email on your phone that happen to be connected with all your devices in home. Just imagine being able to hack someones toaster. And believe me, people are going to try hack everything the can.
No, never. I have heard about IoT but not about 5G. I have barely seen any difference between 3G and 4G.
IoT will revolutionize home industry for example there will be no physical lights switches. Lights will turn on and off automatically There will be some out outlets for old equipment, smart blinds for windows. Well everything will be smarts, and hopefully it will work together.
I’ve heard there was a protest in Poland against 5g but except that It would be all.
2. I don't think that'll be big improvement for smaller shops, cause it will only affect terminal's work. But for bigger organisations which are using self-teaching machines it will be big improvement. Those machines may gather information faster = less time spent on teaching = more money cause time=money. haha :D
For customer: it would be a big improvement for cloud systems I belive and more users will use that technology.
3. I've never been involved in a project related to 5G :/
Today, I am slowly noticing that the 4G network does not keep up with users' needs. I personally don’t need faster network now, but in a few years it may be too slow, it's good to know that soon we will have an improved and faster network.
I think that along with the development of this technology the Internet will be much cheaper, not only the mobile one, but also the stationary one. It will also be possible that people who did not have access to the Internet now will have this easier to get.
I have never delved into the topic of 5G, it was good to read it here, I can’t wait for the technology of everyday life to be developed.
The market of all smart devices is growing really fast. That means that more data is being sent through the network. But I think it will take some time until we will need higher internet speed for that stuff.
I heard about the 5G before but I have never been involved in any project related to it.
"How do you think the world will change with the increase of IoT devices?"
I think that it will certainly improve everyday activities. For Example:
When a user arrives home and his car communicates with the garage to open the door and in the enterprise, smart sensors located in a conference room can help an employee locate and schedule an available room for a meeting, ensuring the proper room type, size and features are available.
"Have you ever heard about 5G or maybe been involved in a project with that technology?" - Only from your article :)
My opinion on the author's second question is that the world will not change. The target provider for the population will change. Soon we will be completely wireless.
Yes, we all heard about the new technology and look forward to implementing it. And I'm waiting.
Have you heard about 5g? of course, I am a programmer that specializes in mobile technologies, but I have not tried to play 5g yet.
I think that IoT improves our everyday life and it's growth can only be beneficial for everyone.
I haven't heard about 5G before. Personally I still felt like LTE was introduced not so long ago so I am glad that this technology is improving at such a rapid pace. It affects many aspects of my life so this is certainly important for me.
I think that people are exaggerating with that. When they saw a faster option than they have then it turns out they need that. For example, 20mb Internet is enough for surfing but I know people who are having 300mb option for that. That's horrible! It's example of consumerism.
I have never heard about 5G because it's not my interest. I know that Internet exist and I'm very happy with that :)
IoT devices will change the world and pretty fast. Smart homes gradually fill the market, smart city technologies are being introduced into big cities. But, question about privacy is still open.
I have heard about 5G in news , but directly I haven't been involved in projects with this technology, maybe in one day.
I think that with the growth of devices world will change very much. I have read a lot of articles on this subject and specialists have very big doubts about the security associated with smart-houses, IoT, because some devices cease to be supported and updated over time. All it takes is that someone finds a bug in the code and can break into any device based on this system. In addition, many experts believe that artificial intelligence can be dangerous for humans
No, I have not heard or participated in a project related to 5G technology.
I think we need to enhance our technologies, and it'll never be "too fast".
2. How do you think the world will change with the increase of IoT devices?
I think the world becomes a better place, when your home is secured with small sensors, your car knows who sit in drivers chair, your phone will show messages only to you.
3. Have you ever heard about 5G or maybe been involved in a project with that technology?
I think everyone in Poland heard about 5G, because of the strange protests against it.
I'm not interested in IoT. I want to leave in an old fashioned way. I like when a fridge is just a fridge and my lamp is only giving a light. I don't want to talk with furniture in my house.
I have no projects connected with 5G internet and I hope that I won't have that type of projects in the nearest future.
The second question is too ambiguous for me. Sure, the world will change. However, I think it’s not related to 5G at all. Most IoT devices operate on low-energy Bluetooth protocols in order to maintain stable connections and save power. The explosion of IoT will only cause BLE to become more popular and will have no effect on cellular networking.
I have heard of 5G only at the university and only as trivia. After reading the blog post, I admit the advancements look impressive and I can’t wait for them to be standardised in the market.
I don't see any reason to prefer slower connection than faster one. I think that 4G LTE is already quite comfortable but if we have faster connection why not use it?
2. How do you think the world will change with the increase of IoT devices?
I think that for last few years we could watched fast growth of computers and smartphones. I think that in the next few years will be work on improvment common things like vacuum cleaners, electric toothbrushes, irons etc. Everything will be connected to the internet and we will be able to manage it by our smarthpone.
3. Have you ever heard about 5G or maybe been involved in a project with that technology?
I have heard about 5G but I have to admit that I don't know much about technical details. I know that it is faster solution than 4G but that's everything what I already know about it.
4G LTE is enough for me, but I don't mind something faster. Right now it's weird for me, that sometimes LTE is faster than normal wired connection. The main advantage for me of LTE is the availability - it's almost everywhere, and you have access to everything instantly.
2. How do you think the world will change with the increase of IoT devices?
It can be only better - I think that it will revolutionize the way we live right now. Imagine the situations, when device will let you simplify a lot of daily routine things.
3. Have you ever heard about 5G or maybe been involved in a project with that technology?
I've heard something about it, but it wasn't that much. Main thing that I've heard is that people think, that it can harm their health - I think that this is not true, and sometimes people act like they live in a Flinstones age.
The world is changing all the time, not even from year to year, and more and more IOT items are going out from week to week. More and more interesting things, I'm curious what will happen next.
I've heard about this technology, but it's hard for me to say something about it.
Would I like more? Of course I would, because why not? I’m using my mobile devices all the time, mainly on surfing the Internet. But you know, it’s not that simple. We will need a whole new infrastructure and new things = lot of money.
I think that IoT is going in great way. It solves many problems and maaaany services will benefit from it.
Yes, I heard about it, but I wasn’t involved in any project with that technology.
2. We can see a lot of IoT devices now for example looking on smart homedevices all connected to the internet like bulbs, toothbrush, vacuum cleaners, electric sockets and so on. Also wearable like smartwatch and in the future maybe something like Intel Vaunt: https://www.theverge.com/2018/2/5/16966530/intel-vaunt-smart-glasses-announced-ar-video
Some devices can increased our free time. In my opinion this is the main advantage.
3. I knew about 5G, but without technical details and I haven't been involved in any project with this tehnology.
I think that with the increase of ioT devices it will simply be more dependent on electricity and all this technology. People will not be able to cope with the situation when technology fails. I've never heard anything about 5G technology. Honestly, I have to catch up.
Noone knows how IoT world would impact on us - humans. For sure it will change some of the aspects of our lives like transport or how we keep our house clean.
I have heard about 5G, but as far as I remember at the time when I heard about it, I was at the very early stage of development.
But I want to have 4G LTE speed everywhere. I mean that there a lot of territories where you have 3g only or even H.
With the increase of IoT devices, everyday life in this world will become even more comfortable. With the growth of AI, the possibilities of IoT devices is growing too. And I will always have work as a Data Scientist :)
Yes, I have heard about 5G. But just only heard and nothing more else.
Technology will go further in our life and take much more space in our life. Smart things are already doing it but it's still kind of outside of our life and IoT will allow it to be symbiotic
It's quite popular but the most gains is for telecom companies.
