The popular American band smoker group posted the news on Twitter. That night, at the Chase stadium in San Francisco, which can accommodate 10,000 people, fans held 5G phones and watched augmented reality effects floating and cracking on the screen.
The signal strength is really moving. After all, the Silicon Star could not find the mobile phone signal in the crowded shopping mall of the Black Five, and the clerk would only regret to say, “Too many people, the network bandwidth is so low.”
Verizon, the collaborator of the smokers’ group concert, can be said to be very hard. In the past year, the four major mobile operators in the U.S. have vie for and grab the 5G network with great momentum, intensively playing the title momentum: “Verizon’s 5G network covers parts of 31 cities and meets the 2019 target” “T- Mobile claims its 5G network covers 200 million Americans “…
Behind the operator’s dazzling hype, mouse users have felt a bit of embarrassment in the US commercial 5G start.
5G speed mystery
But for the daring mouse users, the biggest selling point of 5G is undoubtedly speed.
But the speed of 5G signals in the United States is a mystery.
It is sometimes fast. Electronic enthusiasts are searching for 5G signal towers on the streets of Chicago, and have measured a download speed of 1.25G per second, with an average of more than 500 megabytes. Compared with the download speed of more than 200 megabits per second for 4G signals, this speed is very excellent.
But sometimes it is very slow. For example, AT & T’s low-band 5G network now covers at least 32 million people. On the other hand, the measured average download speed of the AT & T low-band 5G system is 77.7 trillion and the upload speed is 18.11 trillion. The nationwide Galaxy Note 10+ phone running on AT & T has an average download speed of 61.7 trillion and an upload speed of 10.35 trillion.
This is a bit embarrassing, it seems that nothing is faster than 4G. In this battle for 5G, the four major operators have played a lot of tricks in terms of coverage and speed.
T-Mobile has described itself as “the first 5G network covering the United States.” But a user needs to travel to Miami to try 5G because T-Mobile does not have a 5G signal in the Bay Area.
T-Mobile has been ridiculed. Its current average download speed on the 5G network is 61.25 trillion, which makes T-Mobile the slowest 5G operator and slower than many 4G networks around the world.
What is worth paying attention to is the strategy of 5G promotion by American operators, which is divided into low frequency band, middle frequency band and high frequency band to roll out 5G network. Operators do not have the capital to launch extremely fast 5G network signals in all regions.
Just like Verizon’s 5GUWB, this is a true high-band 5G signal mark. It is the frequency band that 5G can play the most speed and passion, but also the frequency band that can achieve more than 1G download speed.
But high-frequency millimeter waves have many limitations. For example, millimeter waves can only travel a short distance, about 1,000 feet, and they will be obstructed by walls, leaves, and human bodies. The signal on rainy days will also be bad. Therefore, its application scenario can only be in densely populated cities, and 5G cellular relays must be installed in buildings and in each city block.
The media estimates that installing repeaters on 13 million telephone poles can provide 5G speeds to more than half of the US population, with installation costs of approximately $ 400 billion.
However, large-scale installations of cellular repeaters in rural areas where the population is sparsely populated may not even pay for them. So these areas are more suitable for low-band 5G. A low-band 5G tower can serve customers within hundreds of square miles and even cover remote and rural areas.
Unfortunately, a large portion of Americans live in sparsely populated suburbs. Beyond that, IF 5G will be the best choice for 5G distance and performance. At the same time, Verizon also reminded users that 5G signals in the mid-band may be similar to 4G.
Have you changed your 5G phone?
Another big issue that troubles mobile phone users in 2019 is whether to change to a 5G phone or buy an iPhone 11.
If you live in a big city in the U.S. and are not bad money enthusiasts, there are usually only two options in front of you: Samsung Galaxy Note 10 Plus 5G is priced at $ 1300, while OnePlus 7T Pro 5G Mclaren is priced at $ 900.
But in order to use 5G signals, YouTube bloggers need to drive to the nearest city with 5G signals, and look for these areas with fast 5G signals, specifically to the streets of Lincoln Park in Chicago and the streets around Bryant Park in New York City. I walked a few streets with a 10,000 yuan cell phone and looked for a 5G signal with my cell phone.
At that smoke and ghost concert, although Verizon turned on 5G signals at the San Francisco Chase Center, only selected participants could access the network and watch the band perform through an augmented reality lens.
No wonder the slightly conscientious technology media are dissuading consumers from buying 5G phones in 2019.
When electronic enthusiasts posted out-of-the-box photos of 5G mobile phones on Reddit, netizens were dismissed:
“5G is currently very unreliable, only used in a few cities, and can only be fully utilized outside the direct line of sight of the signal tower. In another 1-3 years, the signal should not be a problem.”
“What’s wrong with spending more than $ 200?”
Samsung Galaxy Note 10 Plus 5G is a well-deserved star, appearing frequently in videos of tech influences testing 5G signals. Samsung Mobile announced this month that it has sold 6.7 million 5G phones in 2019. Although it consumes a lot of power and is prone to overheating, the tyrants still spend a lot of money.
However, China’s 5G mobile phone sales have reached 17 times the United States. But even analysts in the United States have acknowledged that the United States is afraid to lose to China in rolling out the 5G war. China ’s signal base station construction speed and capital preparation will be more ideal than American operators …
It is said that in China, whether or not to replace 5G mobile phones is another matter.
The reason for persuading the party is: Don’t compare speed with infrastructure madness.
5G does take some time to roll out, but it’s like “When the aunt selling vegetables at the market knows that Bitcoin makes money to enter the market, it’s time to withdraw from the currency circle!” Competition between companies has begun.
In 2020, the goals shouted by operators and enterprises are: reducing the price of mobile phones, increasing network speed, and finding more 5G application scenarios.
According to CNET, AT & T and T-Mobile will each provide at least 15 5G phones this year. At least one of these devices may be an iPhone, which is expected to use Qualcomm’s modem for 5G connectivity by the end of 2020.
Durga Malladi, general manager of Qualcomm 5G, also said at the Qualcomm Summit: There will be new devices with 5G, such as 5G-based notebook computers. Verizon and Amazon Cloud Services announced an edge computing partnership.
However, the application scenario of 5G still seems a bit monotonous, because most of the examples cited in the promotion are all the key technologies of the new Internet of Things will be connected together, remote robot surgery, autonomous vehicles on the road.
5G chronic poison?
It is not just the lack of funds that hinders the development of 5G in the United States, but also folk science.
In Chicago, where the 5G network has been laid, residents have organized anti-5G teams to fight the 5G signal, and petitions to stop the development of 5G.
The slogan of the petition is amazing: “The new 5G signal is coming, and it will kill us all. This is not a joke!” More than 30,000 people have signed.
Although “aside from the dose, toxicity is a hooligan”, according to this logic, eating kimchi may also cause cancer.
But in the United States and internationally, a series of petitions against 5G are also vigorously launched.
The petitioner has a clear understanding of the future brought by 5G: we will have “smart” houses, “smart” enterprises, “smart” highways, “smart” cities, and autonomous vehicles. From refrigerators and washing machines to milk cartons, combs and baby diapers, almost everything we own and buy will include antennas and microchips and will connect wirelessly to the Internet. Everyone on the planet has instant access to ultra-high-speed, low-latency wireless communications from anywhere on the planet, even in the rain forest, central Ocean, and Antarctica.
“Despite widespread denial, there is endless evidence of the harmful effects of RF radiation on life. Clinical evidence of human illness and injury, experimental evidence of damage to the DNA, cells and organ systems of various plants and animals, and epidemics Scientific evidence shows that the major diseases of modern civilization (cancer, heart disease and diabetes) are largely caused by electromagnetic pollution, and a literature base of more than 10,000 peer-reviewed studies has been accumulated. “
“If the telecommunications industry’s 5G plan is realized, then no one on the planet, no animals, no birds, no insects, and no plants can avoid being exposed to RF radiation levels 24 hours a day, 365 days a year. It ’s hundreds of times, there is no chance of escape. These 5G plans have the potential to cause severe, irreversible effects on humans and permanent damage to all ecosystems on the planet. “
Although there is nothing to say about this kind of judgment, the influence of public opinion has been very wide. Even under the promotion of the popular band such as the smoke and ghost group, fans are talking about the legality of the chronic poison of 5G base stations.
“Smoker songs and 5G are slowly killing me, and I won’t go to the concert.”
