4G – the mobile network that’s used around the world to make calls, send messages and surf the web. Now there are plans for 4G to be replaced by, you guessed it, 5G – a new, faster network that has the potential to transform the internet. 5G is a software defined network – it means that while it won’t replace cables entirely, it could replace the need for them by largely operating on the cloud instead. This means it will have a 100x better capacity than 4G – which will dramatically improve internet speeds.
For example, to download a two-hour film on 3G would take about 26 hours, on 4G you’d be waiting 6 minutes, and on 5G you’ll be ready to watch your film in just over three and a half seconds. But it’s not just internet capacity that will be upgraded. Response times will also be much faster. The 4G network responds to our commands in just under 50 milliseconds. With 5G it will take around one millisecond – 400 times faster than a blink of the eye. Smartphone users will enjoy a more streamlined experience but for a world that is increasingly dependent on the internet just to function, a reduction in time delay is critical.
A specialized agency at the United Nations that develops technical standards for communication technologies is International Telecommunication Union (ITU). This body proposed rules for radio spectrum usage and telecommunications inter-operability. In 2012, the ITU created a program called “IMT for 2020 and beyond” (IMT-2020) to research and establish minimum requirements for 5G. After years of work, the agency created a draft report with 13 minimum requirements for 5G in 2017.
Self-driving cars, for example, require a continuous stream of data. The quicker that information is delivered to autonomous vehicles, the better and safer, they can run. For many analysts this is just one example of how 5G could become the connective tissue for the internet of things, an industry that’s set to grow threefold by 2025, linking and controlling not just robots, but also medical devices, industrial equipment and agriculture machinery. 5G will also provide a much more personalized web experience using a technique called network slicing. It’s a way of creating separate wireless networks on the cloud, allowing users to create their own bespoke network.
For instance, an online gamer needs faster response times and greater data capacity than a user that just wants to check their social media. Being able to personalize the internet will also benefit businesses. At big events like Mobile World Congress for example – there is a mass influx of people in one particular area using data-heavy applications. But with 5G, organizers could pay for an increased slice of the network, boosting its internet capacity and thus improving its visitors’ online experience. So when can we start using 6G?
Well, not yet and according to some analysts not until 2024. 5G was created years ago and has been talked up ever since. Yet it’s estimated that even by 2022, the network will still lag behind both 4G and 3G in terms of global mobile connections. Its mainstream existence faces multiple hurdles. The most significant of these of course is cost. According to some experts, 6G could cause network operators to tear up their current business models for it to make business sense. In the U.K. for example, 3G and 4G networks were relatively cheap to set up because they were able to roll out on existing frequencies, on the country’s radio spectrum. For 6G to work properly however, it needs a frequency with much bigger bandwidth which would require brand new infrastructure.
Some analysts believe that the extensive building and running costs will force operators to share the use and management of the mobile network.
This has been less of an obstacle for countries like China, who are taking a more coherent approach. The government, operators and local companies such as Huawei and ZTE are about to launch big 5G trials that would put them at the forefront of equipment production for the new technology. That may be at the expense of the West, where there is concern regarding Asia’s 5G progress. A leaked memo from the National Security Council to the White House called for a nationalized 5G network to keep the U.S. ahead of their global competitors. White House officials dismissed the idea, but some experts predict that by 2023 nearly half of all mobile connections in the U.S. will be 5G, a greater percentage than any other country or region. It’s still likely however that much of the West will have a more gradual approach to 5G, driven by competition but with a patchy style of development.
For example, AT&T pledged to start rolling out 5G later this year but in just a handful of cities. For key industrial zones however, it’s predicted the technology will be adopted quickly, while for many in rural areas 5G may be a long way off. But when 5G does establish itself and fulfills its supposed potential, it could even change how we get the internet at home and at work – with the wireless network replacing the current system of phone lines and cables.
It may not happen overnight, but 5G has come and 6G is coming.
6th generation of wireless communication, technically speaking it doesn’t exist yet but that hasn’t stopped the internet from all sorts of wild speculation. Thing is most of the six G info out there is based on a small handful of reports and studies so to help clear up any misconceptions I’m gonna give you a quick rundown of all the things we know for sure about 6G. 2030 Network is going to be look like this as per ITU-T Network 2030 (6G) 6G or whatever it’s eventually called will replace 5G but right now 6G is not a functioning piece of technology and still very much in the research face. The telecom industry is so heavily focused on 5G that it’s been treating 6G like a middle sibling and mom and dad. Big telecom are going to focus on there 5G baby for the foreseeable future. So if the industry is so focused on 5G when will 6G actually launch? Well mobile technology has evolved on a relatively steady basis.One thing is for sure that 6G will be 100 times better than 5G as per initial working by ITU-T and Huawei CEO.
3G came in the early 2000s 4G in the 2010s and 5G in 2020. So it’s reasonable to think that we won’t get 16 until the 2030s. However just because we may not see 6G for 10 years doesn’t mean it’s not being worked on right now just like with 5g most major companies and governments will work on 6G projects and several already are talking about plans. For 6G Network readiness Huawei has its Overview New IP Networking & Intrinsic Security Framework.
Japan has most recently launched its 6G project both Samsung and LG have 6G research centers in South Korea Huawei also reportedly started its six-G research and even in the US, President Donald Trump tweeted in February of 2019 that he wanted 5G and even 6G technology in the United States as soon as possible.
Everyone is already hopping on the 6G bandwagon even the Donald all these different governments and companies are starting to work on 6G but we can not tell yet who will have the fastest 6G. No but that hasn’t stopped experts from guessing. One expert claims 6G could deliver mind-boggling speeds of one terabit per second or 8000 gigabits per second. 100 times faster than that of 5G. Forget using 5G to download just one movie in a few seconds from Netflix. With 6G speeds in just one second you could download the entire stranger things series seven times over or download a hundred and forty two hours of Netflix movies. It’s great to talk about what 6G could do but since it’s just a pie in the sky idea at this point. Why does it matter to you ?
Well it’s going to be like 5G but more so even higher speeds lower latency and masses of bandwidth. Researchers and scientists are even talking about 6G being the network to move away from wires and use our devices as antennas to create a decentralized network that’s not under the control of a single network operator. So 6G could be the generation to take the power away from the big telecom companies and give it to the people. 5G is expected to take tech that already exists like autonomous cars, drones and smart cities to the next level but 6G may bring to life futuristic ideas like the integration of our brains and super computers technology could soon tap into our bodies through something like a contact lens and shows a different world than reality. 6G network slicing is going to be biggest challenge and how the carrier-assist solution can be used for automation, assurance, and optimization of transport slices ?

table of ContentsBasic Concept
6G, the sixth-generation mobile communication standard, is a conceptual wireless network mobile communication technology, also known as the sixth-generation mobile communication technology. The main promotion is the development of the Internet.
The 6G network will be a fully connected world integrating terrestrial wireless and satellite communications . By integrating satellite communications into 6G mobile communications, seamless global coverage is achieved. Network signals can reach any remote village, allowing patients in the mountainous areas to receive telemedicine and children to receive remote education. In addition, with the joint support of global satellite positioning system, telecommunication satellite system, earth image satellite system and 6G ground network, the ground-to-air full coverage network can also help humans predict the weather and quickly respond to natural disasters. This is the future of 6G. 6G communication technology is no longer a simple breakthrough in network capacity and transmission rate. It is more about narrowing the digital divide and realizing the “ultimate goal” of the Internet of Everything. This is the meaning of 6G.
The data transmission rate of 6G may reach 50 times that of 5G, and the delay is reduced to one-tenth of 5G. It is far superior in terms of peak rate, delay, traffic density, connection density, mobility, spectrum efficiency, and positioning capability.
On November 3, 2019, the Ministry of Science and Technology, together with the Development and Reform Commission, the Ministry of Education, the Ministry of Industry and Information Technology, the Chinese Academy of Sciences, and the Natural Science Foundation of China, organized a 6G technology research and development work kick-off meeting in Beijing. The meeting announced the establishment of the National 6G Technology R&D Promotion Working Group and the National 6G Technology R&D General Expert Group .
On November 20, 2019, the 2019 World 5G Conference was informed that China Unicom and China Telecom have respectively launched 6G-related technology research.
In 2019, the world’s first 6G white paper “Key Drivers and Research Challenges for Ubiquitous 6G Wireless Intelligence” was released. The white paper pointed out that most of the performance indicators of 6G will be 10 to 100 times higher than that of 5G. In the 6G era, it is possible to download 10 HD videos of the same type in one second .In 2018, Finland began to study 6G related technologies.
On March 15, 2019, the U.S. Federal Communications Commission (FCC) unanimously voted to open up the ” terahertz wave ” spectrum, with a view to one day being used for 6G services. From March 24 to 26, Finnish Lapland held an international conference on 6G.
The European Union and Russia are also intensively carrying out related work.
Both Samsung Electronics and LG Electronics set up 6G research centers in 2019. On July 14, 2020, Samsung Electronics released the “Next Generation Hyper-Connected Experience” white paper.
On April 8, 2020, the Ministry of Internal Affairs and Communications of Japan announced the strategic goal of establishing 6G main technologies in the country by 2025, hoping to realize the practical use of 6G in 2030.  In the same year, scientists at the Skolkovo Institute of Science and Technology developed a technology and developed equipment for the development of components of Russia’s sixth-generation communication system (6G). The equipment developed by Skolkovo Institute of Science and Technology has opened up new prospects for the development of 6G system components, especially signal converters from terahertz to optical bands. Research in the sixth-generation field is carried out within the framework of the “National Technology Initiative” Wireless Communication Technology and Internet of Things Competence Center. The institute relies on advanced scientific and laboratory facilities and production links with leading Russian companies in the research and development process. The new device allows the simulation of optical radiation with a wavelength of 1.5 microns and an electrical signal with a frequency of 10 GHz.
Related progress: On September 1, 2020, a news report stated that a major breakthrough in the research of terahertz photonics components will help create cheap and compact quantum cascade lasers to achieve 6G telecommunication connections.
When the frequency of the signal exceeds 10 GHz, the main mode of propagation is no longer diffraction. For non-line-of-sight propagation links, reflection and scattering are the main signal propagation methods. At the same time, the higher the frequency, the greater the propagation loss, the closer the coverage distance, and the weaker the diffraction ability. These factors will greatly increase the difficulty of signal coverage. Not only 6G, but also 5G in the millimeter wave band. And 5G solves such problems through the two key technologies of Massive MIMO and beamforming. The signal of our mobile phone is connected to the carrier’s base station, and more accurately, it is the antenna on the base station. Massive MIMO technology is very simple to say, it actually compensates for the loss on the high-frequency path by increasing the number of transmitting antennas and receiving antennas, that is, designing a multi-antenna array. The number of transmitted data can be increased under the configuration of MIMO multiple antennas, and this is the spatial multiplexing technology. At the transmitting end, the high-rate data stream is divided into multiple lower-rate sub-data streams, and different sub-data streams are transmitted on different transmitting antennas on the same frequency band. Since the spatial sub-channels between the antenna arrays at the transmitting end and the receiving end are sufficiently different, the receiver can distinguish these parallel sub- data streams without paying additional frequency or time resources. The advantage of this technology is that it can increase channel capacity and improve spectrum utilization without occupying additional bandwidth and consuming additional transmit power. However, the multi-antenna array of MIMO will concentrate most of the transmitted energy in a very narrow area. In other words, the greater the number of antennas, the narrower the beam width. The advantage of this is that there will be less interference between different beams and different users, because different beams have their own focus areas, these areas are very small, and there is not much overlap between each other. But it also brings another problem: the narrow beam emitted by the base station is not 360-degree omnidirectional. How to ensure that the beam can cover users in any direction around the base station? At this time, it is time for beamforming technology to show its magic. Simply put, beamforming technology is to manage and control the beam through a complex algorithm, making it look like a “spotlight”. These “spotlights” can find out where the mobile phones are gathered, and then focus more on signal coverage. 5G uses MIMO technology to improve spectrum utilization. The frequency band of 6G is higher, and the further development of MIMO is likely to provide key technical support for 6G.
2. The indoor positioning accuracy reaches 10 cm, and the outdoor is 1 meter, which is 10 times higher than 5G;
3. The communication delay is 0.1 milliseconds, which is one-tenth of 5G;
4. The probability of interruption is less than one in a million, with ultra-high reliability;
5. The density of connected equipment reaches more than one hundred per cubic meter, with ultra-high density;
6. Using terahertz (THz) frequency band communication, the network capacity is greatly increased. 
2. Technical difficulties in data collection to consumption.
The development of 5G and 6G is parallel, but the large-scale use of 6G is still far away. In response, Yu Chengdong replied: “6G is in development, it is estimated that it will take another 10 years, and is currently doing technical research and standard research, and it has not yet reached the commercial stage.
“The speed of 6G network will be 100 times faster than that of 5G, almost reaching 1TB per second. This means that downloading a movie can be completed within 1 second, and the control of unmanned driving and drones will be very comfortable. Users even feel There is no time delay.” said Wu Qihui, executive vice dean of the School of Electronic Information Engineering, Nanjing University of Aeronautics and Astronautics.
“Academic circles now have different views on the definition of 6G. 5G is mainly to do the preliminary infrastructure construction for Industry 4.0, and the specific application direction of 6G is still in the exploratory stage.” Chairman of the Communication Branch of the Chinese Institute of Electronics, Nanjing University of Posts and Telecommunications Internet of Things The dean of the college, Zhu Hongbo, said that some experts believe that in the future, 6G will be used in scenarios such as space communication, intelligent interaction, tactile Internet, emotional and tactile communication, multi-sensory mixed reality, collaboration between machines, and fully automated transportation.
Imagine that 6G literally could bring on real-life cyborgs it could make charging your phone out of thin air a reality and 6G coverage could extend over oceans and even into space so when we finally colonize the moon you can still FaceTime with your boring earth friends in other words with 6g science-fiction could become science fact 5G is going to change the way. We communicate over the next 5 years but when 6G is finally ready it could entirely change the way we live. When do you think we’ll see 6G ? give us your prediction in the comments.
The main technical differences between 5G and 6G are expected to be the speed and capacity of the networks. As mentioned earlier, 5G is designed to provide faster and more reliable connections, lower latency, and improved capacity for a greater number of connected devices. Some estimates suggest that 5G speeds could be up to 100 times faster than 4G, with latency as low as 1 millisecond.
6G, on the other hand, is expected to build upon the capabilities of 5G and offer even faster speeds, lower latency, and improved capacity. While it is still early days for 6G, some experts believe that it could potentially offer data speeds that are up to 1000 times faster than 5G, with latency as low as a few microseconds.
In addition to the speed and capacity of the networks, there are also expected to be some technical differences in the way that 5G and 6G networks are designed and implemented. For example, 6G is likely to make use of advanced technologies such as terahertz frequencies, holographic beamforming, and intelligent surfaces, which are not currently used in 5G networks.
It is important to note that the development and deployment of both 5G and 6G technology is an ongoing process, and new advancements and improvements are being made all the time. As such, it is difficult to accurately predict exactly what the technical differences between these technologies will be when they are fully deployed.
