Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of 19.42 Mbps. But by comparison 5G promises gigabit (千兆) speeds.
“5G is one of those signs, along with artificial intelligence, of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need high speed.
Augmented reality glasses (AR实境眼镜) and virtual headset (虚拟现实耳机) haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.

【推荐1】SOURCE Global is one of the many companies around the world harvesting water from the air. Named Hydropanels, its devices are powered by built-in solar panels (太阳能电池板).
Atmospheric water generators (AWGs), like SOURCE’s, are machines that produce water from the surrounding air. These devices have been around for about ten years and traditionally they’re based on condensation — cooling water vapor (蒸汽) to collect water drops. This process, however, can use a lot of electricity and only work in places with a high amount of water contained in the air. These are what caused SOURCE to develop a more flexible and practical solution.
Its solar panels power a fan that draws in the air. Inside the device, the air travels through a special material that traps the water vapor to produce water. As it is collected, chemical elements, magnesium and calcium, are added to the water to improve its taste and provide possible health benefits.
In Dubai, where the company’s largest water farm is located, it produces 1.5 million liters of water every year. SOURCE has fixed its Hydropanels around the world at hospitals, schools and worksites that have difficulties accessing water. SOURCE plans to create a plastic-free bottled water brand (品牌) and sell it to hotels and holiday centers at about the same price as other bottled water brands. Its next partnership will be in Saudi Arabia’s Red Sea coast, where a development company is aiming to build 18 hotels that will serve SOURCE’s water.
Over 2 billion people live in countries experiencing high water stress and while many companies working on AWGs hope their devices will help solve this problem, that would be unlikely, according to Keith Hays with Bluefield Research, a company that addresses water challenges. High upfront costs mean it takes around 10 years for AWGs to be cost-competitive, he says and they generally produce a small part of the water that a well or seawater desalination (脱盐) system can supply. Vahid Fotuhi with SOURCE understands the challenges, but he says that Hydropanels help reduce the use of plastics and the environmental footprint, and their selling points remain strong.

【推荐2】Since time immemorial, people have been searching for the fountain of youth. Surprisingly, the dream of human immortality is, according to some scientists, not so far out of reach.
Professor Brian Cox, Google’s Ray Kurzweil, and Tesla head Elon Musk all agree on not only the possibility of human immortality but also that it is not too far away. The solution, they say, is something called the “technological singularity”
The singularity is a combination of humankind with computers, namely uploading the contents of one’s brain onto a hard drive. In that way, a person’s consciousness can stay alive after a physical body gets worse. This is based on the idea that a human brain is simply a machine, and there is, according to Professor Cox, “no reason at all why we cannot simulate (模拟)human intelligence,” using a computer.
Although Professor Cox did not say when the singularity would occur, Google’s Ray Kurzweil predicts that the singularity will happen as early as 2045. By 2100, he says, human body parts will be replaceable by machine parts. Further, by uploading our brains onto a computer, we will be able to toy with it, and become “able to expand the scope of our intelligence a billion fold.
Elon Musk agreed with the assessments of the other scientists, even going so far as saying that the chances that we are not in a computer simulation right now are “one in billions”.
Google is preparing for a future where you can download personalities onto robots. For example, you might be able to download onto your robot a celebrity personality, or of the personality of your deceased grandmother. The search engine giant filed a patent for this download process recently. So they definitely believe that the singularity is just around the corner. All you have to do is hold on until 2045, and soon you can effectively live in the cloud.

【推荐3】Tablets（平板电脑） are useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand? Now something like a tablet-shaped but foldable（可折叠的） phone is about to become available. In February, Samsung and Huawei both introduced foldable phones, the Galaxy Fold and Huawei Mate X separately, to the public for the first time. Mobile phone use has entered the “foldable future”, the Verge noted.
The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want but still fit easily into the pocket. The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers, which could help increase available space to the maximum. In a keynote address, Justin Denison, Samsung’s senior vice president, called the foldable screen “the basis for the smartphone of tomorrow”. “It’s a blank canvas (画布) for us to do something beautiful together,” he said.
So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of ten foldable screens produced were defective or unusable. Today, that 10 percent rate has been improved to almost 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17, 500 RMB. That's a price that few people will be able to afford.
But if the foldable device isn’t going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry expert told The Verge, “Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom.”

【推荐2】Dazzling (眼花缭乱) with their bright colors and eye — catching displays, fireworks light up our night skies during the holidays. However, these crowd -pleasers can have some damaging side effects. Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals — as well as some humans.
The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead — all found in fireworks — have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin (毒素) limits of the United States Clean Air Act.
Once all those chemicals come back down to the ground, they can cause problems too. Debris (碎片) from the fireworks falls to the ground, where animals can bum their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources. Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started:
Sky lanterns — a tradition that originated long ago in the most-populated Asian country.
Party crackers — a favorite in the United Kingdom — give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers.
Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns (号角) and blow up a storm!

【推荐3】In most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters (怪兽). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.
Many teenagers like electronic games so much that they can’t stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked “fire”. They develop pains in their fingers because of the constant pressure. They play and play so that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: The muscles of the wrist and arm become so inflamed and swollen (肿胀的) that they press against the bones. This condition is what doctors now call “Space Warrior’s Wrist”.
Other strange aches and pains are also likely to affect the elbows and shoulders. Another even more alarming problem is shown by the case of a 17-year-old girl which was recently in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness and fell to the floor.
Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.

【推荐1】China’s three major mobile operators on Thursday started their long-awaited 5G service plans with users in dozens of cities. China Mobile,China Unicom and China Telecom announced their monthly 5G plans with prices ranging from 128 yuan to 599 yuan, almost at the same time.
The 5G services are now being used in 50 cities, including Beijing, Shanghai, Guangzhou and Shenzhen. The expectation for the new communication technology has long been high. The three major mobile operators already registered over 10 million wannabe 5G users before the official start.
The country is expected to have over 600 million 5G users by 2025, covering nearly 40 percent of the global total, according to Sihan Bo Chen, head of GSMA Greater China.
Major phone makers are jumping on the broadband wagon (马车). Eighteen types of 5G smartphones were brought out in the first three quarters of this year, and about 787,000 5G phones came into the market, according to a research institute with the Ministry of Industry and Information Technology (MIIT).
Bloomberg News reported that bringing 5G services out to the world’s biggest population should give a push to China’s digital economy, including makers of telecommunications equipment, platforms and applications for the internet of things, autonomous (自动) driving and factory automation. It’s the kind of head start that will be expensive at first but could pay off well into the future.

【推荐2】5G wireless networks are ready to power the cities of tomorrow. However, exact implementation (实施)of 5G will vary from city to city, with each city having its own unique set of priorities, requirements, and objectives.
Since 5G enables countless service possibilities, cities must develop strategies around their specific needs. Business and civic leaders play a decisive role in this process, helping to drive smart city initiatives and ensuring that key infrastructure (基础设施)elements are in place.
Several urban areas, including Los Angeles, Dallas, Houston, Atlanta, and Chicago, are early to benefit from 5G For operators, these large urban centers offer a critical mass of solid infrastructure to support 5G’s complex technology requirements.
Now, regional and local governments play a critical role in positioning their cities to become early 5G adopters. They have a growing responsibility to streamline the permitting process, change fee structures, and minimize regulator hurdles in order lo enable greater 5G implementation.
Efforts are already in full force by industry players to overcome challenges for a smooth build-out in areas where 5G is needed first. As business leaders take a more active role in ensuring that they are well-positioned to better 5G services, they also increase their ability to transform their organizations into smart companies. Peter Linder, head of 5G marketing for North America at Ericsson, emphasizes the critical role individual leaders can play in making 5G and smart cities a reality. “5G will be introduced in urban areas first, driven by consumer and business’s needs,” he says. “Proactive city leaders appreciate the potential value of 5G for developing smart city solutions and will partner with service providers to speed up vital network development.”
The role of business and civic leaders as stimulators for encouraging 5G adoption is decisive to creating smarter, safer, and cleaner cities. The time is right for urban leaders and business executives (执行官)to work together toward making smart cities a reality.

【推荐3】It’s easy to forget what communications life was like before 4G. Since its introduction around 2010, mobile subscribers using 4G have enjoyed excellent connectivity. They can stream music, videos and movies, even while conducting video chats. But over the next few years, the launch of 5G networks around the world will bring in exciting capabilities that are much more advanced and beneficial.
Due to 5G’s higher connection speed, mobility and capacity, this next-generation network is expected to enable innovative software for a range of advanced applications. For example they permit surgeons to perform microscopic surgery from remote locations.
Communications service providers (CSPs) will continue to support existing networks while they invest in new infrastructure (基础设施) to support 5G. In a recent blog, Jean-Pierre Brulard, VMware senior vice president, writes: “For CSPs, it is major project, which is why it is likely that rather than a pure 5G network, the majority of people will see a blended approach, where 4G is available to deliver basic services, and 5G is introduced for specific tasks.
Brulard adds, “With 5G, companies can access the levels and speed of connectivity they need by taking advantage of the game-changing technologies — such as Internet of Things (IoT), edge computing and AI — that are going to shape the next stage of the digital revolution.”
Processing IoT and AI in an accelerated 5G world means computing, storage and networking need to be done closer to the end user, which is different from the traditional data center method of data processing. Organizations can remotely manage, monitor and secure thousands of locations and millions of diverse devices. This helps to ensure the rapid delivery of the latest apps, containers and infrastructure updates.
5G can lead to better, accelerated access to healthcare and education, and people can enjoy safer driving conditions, among other digitally fueled benefits.
