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.

On the contrary, the more sunny days are, the more Vietnamese stars tend to promote these types of costumes more strongly. Each beauty has a different variation, creating extremely interesting additions. “Walk” around the street style of the famous series of beautiful women, the girls will find many suggestions for the ideal mix of clothes, “not touching”. Ha Thu F5 pairs a shirt and jeans by choosing wide-leg pants with torn knees, combined with a crop top. The pair of “powerful” items helped the beauty show off her slim waist, revealing her toned abs and highlighting her stylish style. Dong Anh Quynh “plugs in the box” with a wide white shirt and torn jeans. The secret to making her outfit more eye-catching is to drop the collar randomly, only the front half and not buttoning the sleeves. With flared jeans, Karen Nguyen chooses a plaid shirt with a fitted silhouette. Adding a short bag and high heels is that she has a retro-sounding mix. Van Mai Huong turns the shirt into an outerwear, layering it with crop tops and denim shorts, enhancing her healthy figure. If you love the dynamic style but don’t want to reduce the femininity, women can mix pink sleeveless shirts with flared pants like Kim Dung, adding sneakers is enough. Ky Duyen wrapped a T-shirt into a crop, paired it with wide-leg jeans, showing off her “ant” waist and highlighting her liberal look. Crop top and pants are mixed by Toc Tien with extremely “quality” high heels. Small handbags and mirrored eyeglasses are unique accents for the female singer’s street style outfit.

Crop top is paired by the supermodel with wide-leg pants, combined with sneakers and a cap, excellently “cheat” age. Tieu Vy’s ideal 3-round advantage is cleverly exploited with a tight cut-out shirt, mixed with white flared pants. The beautiful small handbag, bright yellow tone, is an accent accessory that makes the set even more outstanding.

Anthony and his wife invited 9 people to a luxurious gala dinner at their apartment. Snacks such as fruit jelly are contained in large syringes, while drinks are poured into boxes labeled Pfizer, Moderna or Johnson & Johnson – 3 companies that provide Covid-19 vaccines, according to NY Post. “We waited too long to meet everyone. It’s time to have fun again,” Anthony said. The party was planned by celebrity event organizer Amanda Orso. Orso said she has coordinated similar events in other cities like Miami, Florida. “It’s not too ostentatious or cheesy, but elevated to a more elaborate party,” Orso said. Laurence Anthony’s party was nicely decorated. Photo: NY Post. Like Laurence Anthony, Karina Freedman (51 years old, from Manhasset, Long Island), owner of two skin care clinics, also plans a “vaccination party” for mid-May 2021. “Everyone can finally get together and celebrate. Surely everyone will be very happy,” Freedman shared. Freedman plans to give attendees gift bags containing healing crystals with the wishes “Be happy, stay healthy, good luck”. While many people hire event planning services to assist with planning, others only do small parties with relatives and friends. Leticia Rossi and Guilherme Baglioli (living in Austin, Texas) moved into a new home in January 2020. Due to the pandemic, the young couple could not hold a housewarming party. When their areas reopened from March 10 according to Governor Greg Abbott’s decision, Rossi and Baglioli joined a group of close friends for a dinner at home. All had previously been vaccinated. “We finally got to hug and talk to each other. It’s good that everyone is at peace,” Rossi wrote on his personal Instagram page. However, experts say that gathering and partying at this time is too early and risks a stronger outbreak. Although vaccination has been widely conducted and the number of new cases has decreased, the Covid-19 epidemic is still raging in many places across the United States, according to The Guardian. In early March 2021, despite criticism from the US Centers for Disease Control and Prevention (CDC), Alabama, Texas and Mississippi still decided to lift epidemic prevention restrictions, according to the CDC. BBC. Florida beaches are packed with people. Photo: Reuters. In Florida, many young people flock here to party and celebrate spring break when the state lifts anti-epidemic measures. Quite a few people said they were “not in the at-risk group”. Therefore, they are not concerned about Covid-19. And in Las Vegas, after a long closure, pool parties are “covering” again as more and more people are vaccinated. “Four months ago, Las Vegas was like a ghost city. Now pool party participants have to distance themselves. We are required to wear masks outside the pool area,” Alyssa Waggoner (25 years old) told Insiders.

With headquarters in London, UK, the OneWeb company intends to deploy a total of more than 650 satellites in the lower orbit of the Earth, in order to provide users on the ground with high-speed Internet 24 hours a day. day through contact satellites. The company is also competing with billionaires Elon Musk and Jeff Bezos in the race to cover high-speed internet via satellite to anywhere in the world, especially in remote areas. This is the third time the Russian side has launched the OneWeb satellite beam into Earth orbit after the previous two missions took place in December 2020 and March respectively at Vostochny space airport with 36 satellites per launch. The first six satellites of OneWeb were launched from the Guiana launch site in France in February 2019, and last year, the company launched 68 more satellites from Baikonur launch site, Kazakhstan.

5G networks will play a leading role in China’s mobile economy in 2020. On April 19, China’s Ministry of Industry and Information Technology achieved its first achievements in the process of building the world’s largest 5G system. Target 600,000 5G base stations this year By the end of February, China had built a total of 792,000 5G base stations, with the number of mobile terminals connected to the network reaching 260 million. The ministry also estimated that 5G mobile phone shipments in China will account for 80% of total shipments in the second half of this year. China’s mobile network speed ranks fourth among 139 countries and regions, an official who is the Vice Minister of Industry and Information Technology of China said, accompanied by quoting data from a metrology organization. international. China aims to build more than 600,000 5G transmitters by 2021. The Ministry of Industry and Information Technology will shift its focus from “coverage and dissemination” of 5G networks to “improving speed and quality”. China also plans to build a “dual gigabit” network infrastructure that covers urban areas and towns where conditions are met for three years, and promotes the construction and deep coverage of the network. 5G on demand in an orderly manner, the ministry said. 5G creates enormous direct economic production value 5G network creates a driving force for many other industries and fields to develop together. According to the whitepaper on 5G development and the socio-economic impact of technology released by the China Academy of Information and Communication Technologies, the 5G industry created enormous direct economic value during the year. 2020. According to the Chinese white paper, by 2020, the 5G network directly leads to an economic production value of 810.9 billion yuan (about 125 billion USD). The white paper stated that the industry directly generated 189.7 billion yuan in economic value added (EVA) and indirectly generated 2.1 trillion yuan in total production value for the year. 2020. 5G also indirectly brought in about 760.6 billion yuan of EVA last year. “Of the more than 800 billion yuan, half is generated from mobile phone terminals, while about 200 billion yuan is invested in building the Internet,” said Duong Kiet, Owner Chinese telecom company China Mobile, said at a forum of the Uncle Ngao Asia Forum Annual Meeting. Meanwhile, Mr. Ho Hau Con, Vice Chairman of Hoa Vi Technology Corporation, China, said many of these industries have actively promoted 5G application, including healthcare and manufacturing.

Break boundaries in Internet access Elon Musk’s project of covering the Internet around the Earth has begun for users to sign up for testing. You can be one of the first to use this service even while living in Vietnam. Starlink’s ambition is to use 12,000 low-end satellites to cover the Internet to every corner of the globe. So far, this project has been successful in covering all over the Americas with a total of 1,261 satellites in orbit. The billionaire Elon Musk’s satellite Internet project also targets Vietnamese users. Currently, Starlink started allowing users to pre-order to use the service. Accordingly, when accessing the website of Starlink, users can easily choose familiar cities of Vietnam such as Hanoi, Ho Chi Minh City, Hue, Da Nang, Hai Phong, Can Tho … to register for history. use this service. Startlink will start providing satellite Internet services to users in Vietnam in 2022. However, to be one of the first users, users have to pay a fee of 99 USD (about 2.3 million VND) to “book”. Payment will be made via international cards such as VISA, Master Card. The kit offered will include a Starlink satellite pan, WiFi router, power supply, cable, and rack. In case of change of mind, Starlink will refund the deposit to the user. Assoc.Prof.Dr Pham Anh Tuan, Director of the Vietnam Space Center, said that Starlink is a satellite constellation project, in which thousands of small satellites are launched into low Earth orbit (abbreviated as LEO – Low Earth Orbit), located 550km from the ground. Internet signals will be shot from satellites straight down to receivers on the ground, then these devices will broadcast the signal through the local system or directly via wires connected to the customer’s Starlink router. The strength of satellite Internet is breaking down distance limits. Hilly areas, islands, complicated difficult terrain … still have simple internet access Satellite Internet works similarly to cable Internet, except that the system has more moving elements. When the customer accesses, the data request will be transferred from the computer to a satellite internet pan. This pan will broadcast a data request to a satellite orbiting the Earth. At this point, the satellite will send the received request to the ISP. The data is transmitted from the carrier to the satellite, then from the satellite to the satellite Internet pan, down to your router and into the computer. The more satellites, the more stable the signal. These satellites act like base stations, except that they are not obstructed by topographic space. Competition between suppliers According to Assoc.Prof. Dr. Pham Anh Tuan, the appearance of the SpaceX provider will create fierce competition from today’s telecom businesses. However, the bigger problem is that we do not have legal bases to manage cybersecurity for foreign suppliers. Therefore, in the coming time, there will be a need to consider legal frameworks to manage network information security, avoid bad and negative information, affecting socio-economic security. Assoc.Prof.Dr. Nguyen Huu Thanh, Director of the Institute of Electronics and Telecommunications, Hanoi University of Technology, this technology will create a big competition with network operators. Currently, Vietnam’s Internet is also relatively good, has coverage in remote areas, islands, but not as flexible as satellite Internet. Starlink is faster than optical fiber depending on the provider, but it is known that the bandwidth of the satellite Internet is very large, so it will compete greatly with current providers. The important point to compete here is the fee charged by the satellite internet provider, if it is too high, it will also be difficult to attract users. According to Assoc.Prof. Dr. Nguyen Huu Thanh, when the entire Starlink satellite system is put into orbit, this service will provide almost global coverage to populated areas. Users using the service only need to buy a pan to catch the waves, like a pan to watch TV. As for cybersecurity, if we talk about hacker intrusions and users, each person must be equipped with tools to protect themselves. Therefore, this problem is the same as with Vietnamese carriers only. The most important thing is to have fair competition policies, otherwise this market will be lost to foreign hands According to experts, Starlink can have coverage to the country or not depending on the country’s regulations. Currently, many countries have allowed Starlink to operate, but China and Russia will require the service to comply with special rules if they allow Starlink to broadcast on their own frequencies. Some countries prohibit the purchase, sale and use of ground-mounted Starlink receivers. In Vietnam, to manage satellite Internet, it is necessary to soon have appropriate regulations. In terms of feasibility, the cost of Internet services from the orbital satellite cluster is as low as that of Starlink is still 7-8 times higher than the price of fixed broadband Internet service in Vietnam. In the case of being deployed in Vietnam, satellite Internet service will be the solution to the problem of Internet coverage in areas with divided terrain such as hills, islands … In addition, the provision of satellite Internet services using low-orbit satellite beam technology promotes the development of the maritime and aviation industries.

The technology giants like Amazon, SpaceX, OneWeb continuously pour money to invest in satellite Internet. Photo: TechCrunch In recent years, satellite broadband is becoming an increasingly popular way to connect to the Internet. Major space companies are also in the race to build ultra-high-speed Internet services through orbiting satellites. Now, the field is forming a model similar to the “Seven Warring Heroes”. The companies are all moving towards a common goal: competing to be the biggest brand in broadband satellite and SpaceX’s position with Starlink dominance is being challenged. SpaceX’s Starlink project SpaceX boss – Elon Musk Of all the companies, SpaceX is the one involved with the most satellite launches. Its Starlink project has more than 1,350 satellites in orbit and plans to launch 42,000 satellites by mid-2027. Eventually, SpaceX hopes to have thousands of satellites around the Earth to establish a global network. Starlink’s Beta “Better than Nothing” was launched last October and attracted more than 10,000 users in six different countries. Starlink’s business model connects customers directly with satellites without the intervention of telecom companies between the two parties. Users register for Starlink service through the website. Once the order is accepted, Starlink will send the hardware set to the customer, which includes a tripod, WiFi router and satellite antenna. Monthly subscription fee is $ 99, and maximum download speed can reach 210 Mbps. Starlink is expanding rapidly and plans to install antennas on vehicles and connect them to satellite networks. According to the test of Internet analytics service developer Ookla, the download speed when using SpaceX’s satellite Internet is 95% faster than the normal Internet in the United States. Project Kuiper from Amazon The Amazon project is named Kuiper In 2018, Amazon’s Kuiper Project was revealed. At that time, government documents showed that the tech giant was working to build global space-based Internet services. The goal of the project is to launch 3236 satellites into a 630 km long orbit, very close to the 550 km altitude of the Starlink satellite. In January of this year, the US Federal Communications Commission approved the Kuiper Project to launch Amazon satellites into space before July 2029, and connect them to antennas on Earth to provide translation. Internet service. As of July 30, 2026, 50% of the project’s satellites will operate. Like Elon Musk, Jeff Bezos, the boss of Amazon, also owns a private rocket and space service company called Blue Orgin. Although no specific plans have been announced, the company is believed to be in charge of bringing the Kuiper satellite into orbit. OneWeb The Soyuz-2.1b carrier missile carries 36 OneWeb satellites that take off from the launch pad of the Vostocini launch pad. OneWeb is a UK owned broadband satellite provider. It currently has 146 satellites in orbit, 1,200 km from the ground and plans to launch a total of 648 satellites to provide global Internet service. In November last year, the company got out of bankruptcy thanks to the British government and India’s Bharti Group. OneWeb hopes to provide Internet services to the entire UK by June. Its latest service will cover the highest latitudes in the world, including Alaska, Canada, Greenland, Russia and Nordic countries. This British company provides a B2B model, provides satellite Internet to telecom companies, then the telecom companies deliver services to customers. Both SpaceX and OneWeb launched satellites into space on March 25, clearly showing a race between the world’s two leading powers in space technology. Hughes Net Satellite team Hughes Jupiter 2 Hughes Net is the largest satellite Internet provider in the United States. It relies on geostationary orbit (GEO) satellites 36,210 km away to transmit the Internet back to earth. The main difference between a satellite operating in low Earth Orbit (LEO) and a geostationary satellite is that GEO satellites can cause delays in video calls and public calls. other technology. However, the GEO satellites are in a fixed position, so unlike LEO satellites, they will not travel in orbit but target a specific area. The Hughes Network has more than 1.5 million users and six satellites in orbit, covering different areas of North America, South America and Canada, including Mexico, Brazil and Chile. The last satellite that Hughes launched was in June 2018 and its goal is to put another satellite, called Jupiter 3, into orbit by the second half of 2022. It is said that this will be a commercial satellite. the biggest ever. Hughes’ satellite service costs range from $ 59.99 to $ 149.99 per month and download speeds of 25Mbps. The kit is priced at $ 249.99, and the installation costs $ 199. The company also offers public WiFi hotspots for rural Latin America for people who cannot afford subscription fees. Telesat Daniel Goldberg, CEO and President of Telesat, Canada’s satellite operator Telesat has 15 GEO satellites at an altitude of 35,000 km above Earth. The company also plans to build an LEO Internet called “LightSpeed”. The first 298 satellites built by Thales Alenia Space are scheduled to launch in early 2023 and provide global services by 2024. According to reports, Goldberg confirmed at the 2021 LEO Satellite Digital Forum on April 6 that the LightSpeed ​​project would cost $ 5 billion. This is much cheaper than the projects of SpaceX and Amazon, which are more than $ 10 billion. Goldberg recently stated that Telesat has the best pricing in the market. In 2019, Telesat signed a launch agreement with Blue Origin to use New Glenn rockets to send LEO satellites into orbit. David Wendling, Telesat’s chief technology officer, revealed that the company has three other startups underway. ViaSat ViaSat application on smartphone ViaSat is headquartered in California, USA, operates five GEO satellites at an altitude of about 35,000 km from the Earth’s surface. The company will put three extremely powerful GEO satellites into orbit by the beginning of 2022 and achieve globalization goals until 2023. ViaSat also plans to put 288 satellites into orbit LEO by 2026. ViaSat executive chairman and co-founder Mark Dankberg said the GEO and LEO satellites would complement each other. ViaSat is working hard to create a “multi-orbit satellite Internet where users can seamlessly use GEO satellites and LEO satellites.” In December 2020, Viasat asked the FCC to study Starlink’s potential environmental impact. In response, Musk wrote on Twitter: “Obviously, Starlink is a ‘threat’ to Viasat’s profits.” Eutelsat Eutelsat is Europe’s satellite operator with 39 GEO satellites at an altitude of 46,000 km. The company now provides Internet services to the regions of Europe, Africa and the Middle East, and plans to launch another satellite called Konnect VHTS to cover the rest of Europe. Michel Azibert, Executive Vice President of Eutelsat, said: “Konnect VHTS will change the rules of the game and allow Eutelsat to seamlessly deliver powerful Internet services to users at prices comparable to the above operators. ground.” Azibert says Eutelsat’s satellite service “is much lower than Starlink, very well suited to the rural markets we’re targeting in Europe, the Middle East and Africa.” Eutelsat was founded in 1977 and launched its first satellite in 1983.

Accordingly, 5G users will be able to use another carrier’s network in places where their service provider does not have coverage. The Ministry of Science and ICT said telecom carriers will test network sharing systems before the end of the year and aim to fully phased in by 2024. Remote areas selected to provide 5G network sharing are sparsely populated, with a population density of 92 people / km2, while areas that do not share 5G networks have a population density of 3,490. person / km2. The move to share 5G networks comes as South Korea is racing to establish 5G coverage nationwide, with network equipment currently installed in major cities. In July 2020, the three major South Korean carriers pledged to invest up to 25,700 billion won (23.02 billion USD) to upgrade the network infrastructure by 2020. As of February 2021, South Korea has 13.66 million 5G subscribers, accounting for about 19% of the country’s total mobile network subscribers. South Korea was the first country in the world to commercialize 5G networks in April 2019.
