The US has a rather slow 5G rollout. Photo: NetEase Since the advent of 5G technology, US carriers have been slow to deploy 5G networks. The main reasons are limited spectrum resources available for 5G, cumbersome deployment of 5G devices, and lack of killer applications for 5G services. The media often uses words like “fast” to describe 5G speeds, but the speed of 5G wireless network rollout in the US has nothing to do with the word. Over the past three years, the prospect of 5G wireless networks has been the focus of major media reports. But for most Americans, the real 5G that can achieve the desired effect is yet to emerge. Although all the major wireless carriers in the country claim that their 5G services have covered the entire US, industry analysts argue that this so-called 5G service is not much different from the US. 4G. According to market research firm Evercore ISI, most Americans may not enjoy 5G service that is significantly faster than current wireless communication networks. “Overall, it is expected that between late 2021 and late 2023, truly better 5G services will cover two-thirds of the US population,” said James Ratcliffe, an analyst at Evercore ISI. The first batch of mobile phones that support 5G networks was launched in mid-2019, according to Ratcliffe, in the most optimistic scenario, wireless network operators will be able to provide “real” 5G services to 2/3 of the US population in the next 30 months. Meanwhile, the first mobile phone to support 4G network was released in 2010, and the US 4G network was basically rolled out 18 months later. Analysts, academics and former industry executives say a combination of factors has resulted in a relatively slow rollout of 5G networks in the US. Some of these problems are related to network infrastructure: high-speed network transmission frequency bands and signal coverage are limited. Moreover, the new network equipment that needs to be on the shelves to deploy 5G networks is relatively cumbersome. In addition, many new devices are not made in the US, so the time to purchase the device will be longer. Industry observers also point out that the current 5G network still lacks breakthrough applications, and cannot stimulate user demand and promote the spread of services such as mobile video in 4G networks. John Roese, chief technology officer of Dell Technologies and a former executive at companies like Huawei and Nortel, said that although wireless operators have recently invested billions of dollars in 5G networks, when Because their revenue in 5G-related businesses is not stable, they may not be able to accelerate the construction of new networks. According to Mr. Roese, wireless network operators have had disappointing returns when investing in 4G networks. He said that the main beneficiaries of 4G networks are technology companies that provide applications and other services through the network. “So wireless operators are very cautious about this.” Limited frequency range Photo: Sina To meet the large traffic that 5G networks have to transport, carriers need to open “highways” for data. The spectrum is similar to the real estate that the government grants to carriers through auctions to build highways. The more land they have, the more lanes they can open for faster 5G and easier access. Currently, 5G networks mainly transmit data through low-band, mid-band and high-band. High-band (mmWave) aka millimeter wave has the highest data transfer rate and largest bandwidth, but the smallest coverage. Low band has wider coverage but slowest transmission speed. Finally, the mid-band is considered to be the balance between coverage and transmission speed. Companies like Verizon, AT&T, and T-Mobile all claim that their 5G networks now cover more than 200 million Americans, enough to meet US demand. However, most of these networks rely on low-band radio waves to complete coverage, and network transmission speeds are limited. Wireless network operators are currently focused on capturing mid-bands and have invested a lot of money in recent tenders for these resources. But the main problem facing these companies is that most of the mid-band bands have been occupied by US government agencies and other agencies, mainly for military communications and meteorological services. . Until now, wireless network operators could only use a fraction of the mid-band resources. US government agencies are also aware of the lack of mid-band resources. Earlier this year, the US auctioned a total of $81 billion in mid-band licenses, and plans to hold another auction this fall. When operators were preparing to roll out 5G nearly 10 years ago, they generally believed that 5G networks would primarily use high-frequency radio waves, said Stefan Pongratz, analyst at Dell’Oro Group. . This portion of the spectrum resource is essentially unused. But Pangraz says that rolling out a 5G network using millimeter waves requires building more base stations, which will certainly take time to increase deployment density of base stations. He said that until recent years, the US turned its attention to mid-band radio waves as a way to roll out 5G networks faster. Where is the profit point? Photo: Justin Hall Comics Brian Kelley, an associate professor of electrical engineering at the University of Texas at San Antonio, said the lack of disruptive applications is another major factor hindering the rollout of 5G networks. Mr. Kelly, who was an engineer at Motorola, said: “It can be said that this is the biggest factor that can stimulate the speed of 5G deployment.” According to analyst Craig Moffett, the 3 main advantages of 5G networks are faster data transmission (100 times faster than 4G), support for a large number of simultaneous connections, but also significantly improved response speed between devices. device is connected. “There isn’t a single revenue model that can combine these three advantages. It’s not even clear if consumers are willing to pay more for faster video downloads,” Moffett said. Moffitt said that because 5G networks can seamlessly connect sensors and other IoT devices, companies will likely be the first adopters of 5G services. He said that 5G networks “can be considered the next generation of Wi-Fi wireless networks, which are faster, more secure and can connect more devices”. But Moffett said the question is: “Will wireless operators build their own 5G networks for enterprises, or will the enterprises themselves deploy them?” This is important, he says, because if businesses choose to deploy their own 5G networks, wireless operators may lose the associated revenue and not be able to invest more money in building infrastructure. 5G layer. Device problem Currently, in the world, there are 5 companies that have successfully produced network equipment for 5G, none of which is in the US. Photo: Sina 5G networks are very different from 4G, in part because 5G networks need to transmit data at a higher frequency band. This means that upgrading 5G networks requires different technologies and devices. Evercore analyst Ratcliffe says installing new equipment can require finding a suitable location, obtaining the right permits, and even digging up roads and laying fiber optic cables to transfer data at high speeds between base stations. Gazzola, chief executive officer of Atlanta-based infrastructure company Bennett & Pless, said it is expected that by 2022, the construction work needed to bring wireless communication networks to 5G standards will increase. . However, the epidemic and technical obstacles have delayed progress. Equipment availability is also a common issue faced by wireless network operators. Dell’s Rose said that when 4G was first introduced around 2010, there were about a dozen technology vendors offering wireless networking equipment, including Canada’s Nortel and America’s Motorola. Today, there are only five major players in the global network equipment market: Nokia, Ericsson, Samsung, ZTE and Huawei. “Two in China. One in Finland, one in Sweden and one in Korea.” These suppliers are all located outside the US. Worse still, 5G network equipment requires computer chips while the chip industry has been struggling recently to cope with supply shortages.

2G network will be “wiped out” by Korea Previously, in July last year, SK Telecom officially stopped providing 2G network service, while another Korean mobile operator, KT Telecom, stopped providing 2G network service since 2012. due to the rapid development of advanced mobile network generations and the significant decrease in the number of 2G network users. 2G mobile service started operating in Korea in 1996 based on the world’s first commercial code-shared multiple access network built by SK Telecom. The number of 2G subscribers nationwide surpassed 20 million in 2006 but began to decline after the country commercialized 3G and 4G networks in 2003 and 2011, respectively. It is known that by the end of March 2021, the number of 5G mobile network subscribers in Korea has reached 14.48 million, accounting for 20% of the total 71.1 million mobile subscribers, according to data from the Ministry of Information Technology. trust this country.

5G smartphones expected to grow by 130% this year năm The pandemic has changed everything, and the needs of users in the smartphone market have also changed. The strong growth of 5G in countries around the globe also leads to a slowdown in demand for 4G devices, and 5G devices will record strong growth and gain a lot of user interest. The smartphone market has returned to growth from last year and continued to grow in the first half of this year, said Ryan Reith, IDC’s vice president of global mobile device tracking. In addition, the price of 5G devices continues to decrease as 5G Android devices will drop 12% year-on-year in 2021, which is a great pressure for Apple devices as its prices are still higher than other devices. others. IDC also expects growth through 2025, with a 5-year compound growth rate of 3.7%. The smartphone market will not be affected by the lack of semiconductors such as automobiles, computers and consumer technology categories. In addition to 5G Smartphones, IDC also reports on the PC market this year. Desktop, laptop and workstation shipments are expected to increase this year despite ongoing semiconductor shortages. IDC’s new forecast in the Worldwide Quarterly Personal Computing Device Tracker says PC shipments are expected to grow 18.1% to 357 million units this year.

The price is 3 times cheaper, no owner needed Specifically, the best-selling cheap 4G SIMs on online markets are usually VinaPhone’s D500, VD149 SIM, Viettel’s V90, V120 SIM, Vietnamobile’s unlimited 4G monthly SIM card or MobiFone’s MDT250A SIM. These are cheap packages, usually in the form of a 1-year package that does not need to be recharged. The convenience of these SIM lines also lies in the fact that users do not need to register the subscriber’s own owner, just buy it and perform the activation operation, the SIM will always be used without the owner’s information. Cheap 4G SIMs that don’t need to be registered are sold widely on online markets. About the price, the same package that the carrier collects monthly from prepaid or postpaid users, these cheap 4G SIMs have cheaper monthly rates, even without monthly payments, just buy SIM card can be used continuously for 12 months. For example, with Viettel’s V120 package, this network operator collects a monthly fee of 120,000 VND per month from registered users, but when using a cheap 4G SIM on the network market, the price of this package is only 90,000 VND per month. month. Deeper reduction can include SIM VD149 of VinaPhone. Instead of paying 149,000 VND per month like a regular SIM, users of cheap 4G SIMs buying on the online market only have to pay a one-time payment of about 680,000 VND to buy a SIM, which can be used for 12 months. This price is equivalent to more than 56,000 VND a month, nearly 3 times cheaper than the price offered by the network operator for the same package. According to the advertisement of online merchants, a cheap 4G SIM is a type of SIM suitable for technology car drivers, students, and users who need to use 4G continuously with large capacity and cheap price. A quick survey shows that the price of this type of SIM ranges from less than 100,000 VND to about 700,000 VND depending on the package and network operator. After ordering a cheap 4G SIM above, Zing quickly receive goods and use SIM immediately, no need to register any subscription information. When looking up subscriber information, the system from the network operator returns information that the subscriber owner is a person named Long in Tra Vinh with the accompanying CCCD number. Also according to the seller, users can send their CCCD information to register the owner for peace of mind to use the SIM for a long time. Share with Zing , a telecommunications expert said that in addition to the risk of being fined for using junk SIMs, buyers and users of non-original SIM cards are also likely to be scammed, buying unusable SIMs such as end. “Besides, when sending information to register the SIM owner purchased online, users are also likely to have their information stolen to register for other non-original SIMs. Most likely cheap 4G SIMs sold on the Internet. The network is also pre-registered using the information of previous customers,” he said. Strongly scan for junk SIM In order to have a “clean” database to deploy new services, the authorities and network operators are stepping up the cleaning of telecommunications junk, including spam SIMs, spam messages and spam calls. Previously, the Ministry of Information and Communications (TT & TT) asked the carriers to directly connect the database of subscriber information registration with the Department of Telecommunications. In addition, develop and apply criteria to prevent suspicious activity on the distribution channel such as not allowing activation at night, activation frequency exceeding 1 subscriber/minute, 100 subscribers/day, registration Sign more than 3 subscribers/1 number of papers. The Ministry of Information and Communications and network operators are stepping up the search for junk SIM and other telecommunications waste. Photo: Ngo Minh. Also according to the regulator, the carriers also deployed an artificial intelligence (AI) matching tool to identify portraits and documents using artificial intelligence (AI) across the entire distribution channel to prevent the use of documents. invalid, use photos instead of real people… Network operators including Viettel, VNPT and MobiFone also offer strong solutions to combat spam such as stopping the sale of network adapters at authorized dealers, stopping the right to connect subscriber numbers of authorized dealers from June 1. 2020. Instead, businesses will focus on selling SIMs and registering subscriber information at their telecommunications service providers. According to the provisions of Clause 1, Article 2 of Decree 49, the act of using someone else’s documents (even if they are lent) or transferring the registered SIM card to another person for use without re-signing the contract will be subject to administrative fines up to 500,000 VND. In addition, according to the Department of Telecommunications, when there are violations of the law, cases related to mobile subscriber numbers are used by individuals or organizations in the name of the subscriber, but not directly but to be used by the person who violates the law, the person in the name of the subscriber is responsible for explaining and proving his innocence when requested by the authorities, even having to bear joint criminal responsibility. if this violation causes serious consequences.

The 5G variant of the Galaxy A22. The camera system on the product includes three cameras, with a 48 MP main camera combined with a 5 MP and 2 MP secondary camera, but the specific function is unknown. However, based on what happened before with the Galaxy A series, it is likely that these secondary cameras will work as macro and depth respectively. On the front, the Galaxy A22 5G phone will have a 6.4-inch screen with Full HD + resolution. Samsung has opted for LCD technology over AMOLED, which explains its use of a side-mounted fingerprint scanner. To support 5G, it uses the same MediaTek Dimensity 700 chip as on the recently launched Realme 8 5G. There is no word on RAM and internal storage yet, but it will have a 5,000 mAh battery. Realme launched a smartphone with 5,000 mAh battery, 33W charging, 90Hz screen, 6 GB RAM, priced at more than 4 million VND As for the Galaxy A22 4G, the LTE variant of this product is very similar to the 5G version but there are some important differences both inside and out. For example, the screen is still 6.4 inches, but the resolution is reduced to HD + and the V-shaped notch has been moved to a U. Waterproof smartphone, S888 chip, 12 GB RAM, 240Hz screen, 2,000 nits brightness The 4G variant of the Galaxy A22. Interestingly enough, Samsung has also ditched LCD technology in favor of an AMOLED display with thinner bezels. That has allowed the company to add an in-display fingerprint scanner, as opposed to the 5G variant. Inside, the device integrates the Helio G80 chip like on the Galaxy A32 4G instead of Dimensity 700, but the battery is still 5,000 mAh. Detailed photos of Asus ZenFone 8 Flip: ‘super terrible’ configuration, 5,000 mAh battery, 90Hz screen, rotating camera, priced at more than 22 million The rear camera part is also a bit different from the 5G variant when it equips up to four cameras, including 48 MP, 5 MP, 2 MP and 2 MP respectively for main, ultra-wide, macro and camera functions. deep. See the waterproof smartphone, the world’s best screen, S888 chip, 12 GB RAM, ‘super big’ camera Both the Galaxy A22 4G and A22 5G are expected to be announced in the coming months, even weeks. Their prices have not been announced yet, but the images shown above show they come in four color options, including Black, Purple, White and Green.

This fake website used logos and was designed with many colors that are quite similar to the official website of Viettel, causing many customers to confuse that this is the official website. Interface of fake Viettel website to sell 4G SIM cards. At the bottom of the website, the operator is also specified as Viettell Trade and Import-Export State Company Limited. Business registration number 0102831022 by the Department of Planning and Investment of Hanoi for the first time on 25/01/2006. In which, word Viettel is written with 1 letter “l”. Besides, while Viettel Group has changed the whole brand identity, this fake website still uses the old corporate brand identity. “The Vietnam Counterfeit Information Processing Center warns the online community not to use the service of this fake website. The case will be transferred to the authorities for consideration and handling in accordance with the law”, the unit this said. Recently, on many online markets, groups about SIM cards recently appeared to advertise for 4G SIM cards with up to 1 billion GB of high-speed capacity with a fee of less than 100,000 VND. Exchange with Zing MobiFone representative affirmed that all posts on social networks related to the distribution of 4G SIM cards with a capacity of up to 1 billion GB with low rates are scams. Currently, this network operator does not have any SIM types and packages like the ads above. The representative of the operator affirmed that users should not buy SIM from the above objects as well as recommending that customers can refer to the most accurate products and services at MobiFone stores as well as through main sales channels. other business formula. With the use of unknown SIMs as above, the operator representative said that users may have the possibility of leaking personal information or buying a SIM that cannot be used even after paying full payment for the object.

Regarding the tariff, these 4G SIMs are advertised only need to pay 25,000 – 50,000 VND per month. This is a very cheap fee for 1 billion GB of 4G high-speed capacity. Currently, carriers sell popular 4G packages at VND 70,000 / month with a capacity of no more than 4 GB. Posts about 4G SIMs have 1 billion GB of high-speed capacity per month and cheap rates are rampant on internet markets. Contact one end of each selling SIM type, Zing receive a quote of 99,000 VND for the SIM in which the package has not been activated, activate it by itself when receiving the SIM or 150,000 VND for the activated SIM, only use it. Also as noted, all 1 billion GB 4G SIM card advertising posts use MobiFone’s SIM embryo image. Exchange with Zing The representative of MobiFone confirmed that all posts on social networks related to the distribution of 4G SIM cards with a capacity of up to 1 billion GB with low rates are scams. Currently, this network operator does not have any SIM types and packages like the ads above. The representative of the operator affirmed that users should not buy SIM from the above objects as well as recommending that customers can refer to the most accurate products and services at MobiFone stores as well as through main sales channels. other business formula. With the cases of using the SIM of unknown origin as above, the representative of the carrier said that the user may have the possibility of leaking personal information or buying a SIM that cannot be used even after paying full payment for the object. In addition, the Telecommunications Department said that according to the provisions of Clause 1, Article 2 of Decree 49, the acts of using papers of other people (including being loaned) or transferring their registered SIMs to others to use. Failure to re-enter the contract will be subject to an administrative fine of up to 500,000 VND. In addition, when there are illegal acts, cases related to mobile phone numbers, which are held by the individual or organization under the name of the subscriber, but not directly used by the operator, but to the operator. violating the law of use, the person under the name of the subscriber owner is responsible for explaining and proving his innocence when requested by the authorities, even jointly liable for criminal action if this act Causing serious consequences.

Send a petition to Ho Chi Minh City Women’s Newspaper, Ms. TBC – in Thu Dau Mot city, Binh Duong province – said that she had just been stolen by an object, appropriated more than 58 million dong in credit card. Ms. C. said, on March 2, she saw the phone displaying a message “unable to call”. The next day, she went to VNPT Binh Duong Business Center to check and rebuild a new sim, but the staff said that the sim card was not damaged, it was still working in two directions; “Cannot call” may be caused by phone malfunction. A fake message on the network operator calling for users to upgrade to a 4G sim. Phone subscribers need to be very wary of this kind of message – Photo: Provided by Competition and Consumer Protection Department On March 4, she asked to renew a new sim and a new one to work properly (listen, call). On March 12, when she accidentally read an article about the theft of money from her credit card, she immediately logged into her Fe Credit credit card account to check, and discovered that the money in the account was completely withdrawn in the form of purchase payment. Suspecting that her sim information was leaked during the sim remake process, Ms. H. came to complain at VNPT Binh Duong Business Center, just learned on March 2, there was a transaction to replace her sim card in Ho Chi Minh City. “I live in Binh Duong, have never made a transaction to replace my sim card in Ho Chi Minh City. VNPT Binh Duong Business Center also confirmed to only perform one SIM replacement transaction in Binh Duong. Thus, there is a fraudster who falsified my papers to perform a sim replacement transaction in Ho Chi Minh City and then appropriated property “- Ms. C. said. Not long ago, Dang Thanh Hai – in Ho Chi Minh City, the owner of a Viettel subscriber – suddenly blocked his mobile phone number, then was withdrawn 30 million dong from his bank account. Mr. Vu Minh Nhat – in Hanoi, the owner of a Mobifone subscriber – also had his sim stolen and then hacked into his bank account, losing 74.8 million dong via online payment. In the above two cases, the fraudster used a notarized copy of the identity card (ID card), went to the phone store (also the agent of the network operator) to register the procedure. In the case of Mr. Hai, the employee does not compare the copy of ID card with the original ID card; In the case of Nhat, the staff did not see the original ID card, nor did they require the latest contacts to verify. Recently, Thanh Hoa City Police, Thanh Hoa Province prosecuted seven subjects for counterfeiting ID cards according to customer information and then pasted their photos, to transaction points of network operators such as Viettel, Vinaphone to report the loss of their sim cards. suggest to redo the sim with the old number After being granted phone numbers from the carriers, the subjects used fake IDs and stolen phone numbers to make unsecured loan contracts from Fe Credit with loans from 20-70 million VND, appropriating a total of 500 million dong. The network operator can not be indifferent In the case of Ms. TBC, the representative of Vinaphone’s mobile phone network admitted, Vinaphone staff made a mistake in the process. Rather, in order to be reissued (in case of no sim), the subscriber must present his ID card, fill out an application form to reissue the sim, provide five outgoing and five dialed phone numbers. come. But the transaction staff in Ho Chi Minh City did not ask the replacement sim (the fraudster) to present ID card, just provide five phone numbers to call out and call. As a result, the fraudster easily obtained the sim of Mrs. C. and then appropriated more than 58 million dong in the credit card. Why does the fraudster know the five dialed and dialed numbers of the sim owner? According to Mr. Vo Do Thang – Director of Athens International Security and Network Management Training Center – the crook can use many of his own sims to phone, send text messages to the subscriber owner to call back and easily get the list. these calls. The situation of sim theft is happening more and more, but the network operators have not changed the sim re-issuance process as well as require transaction staff to be more cautious in re-issuing the sim, in order to ensure safety for customers. According to Mr. Vo Do Thang, the easy re-issuance of sim cards has created a gap for the fraudster who steals the sim. Employees often check for passport or not check, while counterfeiting ID is not difficult; Furthermore, they also have no inspection skills so it is difficult to detect tampering. “If the network operator takes one more step, such as issuing a password when issuing the sim for the first time, there is a secret question that only the subscriber knows, using artificial intelligence to detect the sim owner’s face … Having forged papers, it is not possible to steal the sim card ”- Mr. Vo Do Thang proposed. The representative of Vinaphone added that this company had collected information related to the theft of Ms. C.’s sim and transferred it to the police station to assist the victim. According to FeCredit Finance Company, because Mrs. C. was not at fault in this case, she is not responsible for the lost credit card amount. Why do I lose money in credit card when I lose my sim card? Most of the victims in the sim lost cases are stolen money by fraudsters by making online payments. Three factors are required to pay for online purchases: First, a mobile phone number – the credit card holder must register this number with the bank to authenticate transactions and receive bank notices. Second is the card number (the serial number printed on the front of the credit card). Third is the OTP authentication code (one-time password) sent via registered phone number with the bank. According to Mr. Vo Do Thang, the victim’s credit card number has been stolen by the fraud before, the sim theft is just the last step to steal money. After the sim is stolen, the fraudster will take the victim’s credit card number to pay online, then use the sim to receive the OTP code. Therefore, not everyone who loses their sim card will lose money in their credit card, in their bank account, only when they have revealed their credit card or account information before that the fraudster can steal the money. The victim’s credit card information may be exposed during previous online transactions by entering fraudulent websites, being infected with malicious code on the phone to steal card information or possibly due to The credit institution does not guarantee security. According to Mr. Vo Do Thang, criminals just need to steal credit card information, steal sim cards, and get OTP codes to steal money in the victim’s account shows that it is a great risk. Online payment processes of most credit institutions are still lax. “In this situation, the most important card users need to closely protect their card and account information, to avoid providing it to strangers. Absolutely do not visit strange websites or open attachments that are sent to unknown origin to avoid being installed with malicious code. Should be equipped with anti-virus software, anti-software with self-copy function (Trojan), keyboard manipulation monitoring programs (Keylogger), equipped with firewall protection … (According to Women HCMC)

6G technology will appear around 2030 Mr. Eric Xu also noted that Huawei is currently working to determine the key specifications of 6G technology, and the company may soon release a white paper on 6G. “We are working with other players in the mobile industry to determine what 6G really is,” added Mr. Eric Xu. Maybe in the near future, we will release our 6G white paper “. Mr. Eric Xu stated that the future development of 6G will depend on potential use cases that need the support of this technology. “If Huawei or the global industry has limited imagination and if we can’t come up with a compelling use case for 6G, then maybe 6G won’t be necessary. If all the use cases for 6G that the industry will come up with could be supported by 5G or 5.5G then we wouldn’t need 6G. Then we may need to wait for our next generation, who might be smarter than us and have different needs. They may come up with some use cases that only 6G can handle. That will be where 6G can find its value… ”, analyzed Eric Xu. In preparation for the next generation of mobile technology, the Chinese government has begun researching 6G technology. According to Chinese state media reports, government agencies and research institutes had initial meetings with the aim of establishing research and development groups. 6G technology National level. China’s Ministry of Science and Technology said it would set up two working groups to carry out 6G research activities. Meanwhile, earlier this week, the German government said it plans to finance up to 700 million euros ($ 833 million) for research on 6G technologies by 2025. In a statement, the Ministry of Education Education and Research The German Federation (BMBF) said it started Germany’s first research initiative on 6G technology this week. Besides China and Germany, many other countries in the world have also planned and invested in the research and development of 6G technology such as the US, Korea, Japan, France and Finland.

In addition to a number of corporations such as Samsung Electronics, LG Electronics of South Korea and Huawei of China, most recently, Apple (the US technology corporation) also announced to recruit engineers to participate in research and development. to develop wireless technology next generation 5G. According to current research directions, the theoretical speed of 6G network will be one Tb / s, about 100 times higher than the theoretical speed of the 5G network (10 Gb / s). The new technology will also have broad coverage and be more energy efficient than the previous generation. Most importantly, 6G hopes to solve the limitations of current 5G networks. Specifically, even though it is considered as an Internet of Things (IoT) network, 5G still has a long way to go to achieve universal universality due to its limited ability to transmit signals at a height of many thousand meters. ground or deep below the ground or seabed. Meanwhile, 6G is research-oriented to meet both intelligent connectivity, deep connection, heterogeneous connection and everywhere. On the other hand, although 5G network has helped people make good use of artificial intelligence (AI) technology to optimize, distribute resources and process data, the forecast 6G network can do better by making AI becomes intelligent with the processing speed close to the human brain. 6G will integrate the new physical, digital, and services worlds to deliver stricter network performance metrics (KPIs) than 5G. However, the development of 6G networks is still just beginning and the end result will depend on speed of deployment and consensus on the technologies to deliver the ultimate standard. Experts say that the next 10 years will be a period for research and 6G will start to be commercialized from 2030. In the process of deploying previous generations of mobile networks such as 2G, 3G or 4G, Vietnam often lags behind the world. As for 5G networks, we are now starting to perform tests with the expectation of entering the first groups of countries to deploy the technology. But according to experts, in fact, Vietnam is still quite far away from the world in terms of research capacity and deployment methods in the telecommunications sector. Therefore, even though all countries have the same opportunity in terms of time to lead the research and deployment of 6G networks, not all countries have enough potential in science, technology as well as finance. join the race for core technology of 6G right now. Instead of racing to research core technologies, we should take advantage of other existing strengths to catch this wave, such as: Focusing on research and production of terminals for 6G; researching in-depth in the control and optimization of the 6G network system; research on AI technology for management system, data processing in 6G network system; blockchain security research (blockchain) … to solve the safety problem in the new network system. This may be a medium and viable market for Vietnam in the future.
