With the iPhone 12, it is only a year away from a quarter. At this node, I was lucky to receive the Nelkin magnetic suction and lens painting protective case from ZEALER. Especially in the form of the Guangzhou epidemic, it is very happy to be able to sit quietly in the residence and experience the product slowly. Next, I will share the experience of the whole set of products under the shell film + wireless charging.

iPhone 12 magnetic + lens sliding cover protective shell & film:

Green

1. The skin-friendly is particularly strong, the patented sliding cover lens protection design is easy to use, and the lens ring has a unique heightening to prevent the lens from scratching and dusting.

2. The official display shows that there are 38 built-in magnets, which is convenient for magnetic charging, and the Magsafe is stable when it is sucked in.

3. The inner lining is soft fiber, which can better protect the body. The back is also very simple. 4. The body is surrounded in place, and a relatively protective layer can be felt almost all over the body. However, the same skin-friendly soft glue as the surface is used directly at the interface position and button position of the mobile phone, which is very good for the protection of the product. Will affect the use. 5. It feels a little tight to use. Black Mirror Pro sliding cover goggles: 1. The design is really steel. Looking at the business, it feels like a military industry when holding it. The gap between the sliding cover and the shell is tight, and there is a hidden buckle designed to prevent the lens cover from loosening. 2. The hand feeling is naturally a protective hand feeling. When I put it on my hand, the strong scratching feeling of the original iPhone 12 is gone, but the overall feeling is the kind of friction that is protected in place. It does not increase the friction of the hand and it is durable. Carefully on the ground, nothing happened when I picked it up. This picture was taken after I fell, and there is no trace of falling. 3. Looking at the material, the original side is TPU soft glue, which is very friendly to the button interface, etc., while the back is the PC back shell, which is still very good for product protection. 4. Magnetic attraction is also very powerful. Correspondingly, it will naturally be a little heavier if the material is full. Full screen privacy protection film 1. The packaging is very different. In addition to the film itself, it also brings a small thing similar to paper towels. More importantly, it is the gospel of a handicapped party-the film applicator, which can be applied directly, and it can be applied without too much effort. . 2. 28-degree side anti-peep, anti-fingerprint, full coverage, with dust-proof net, 0.33 slim, sensitive to the touch, very friendly to use, but face recognition occasionally affects. 3. Anti-peeping is really useful, you don’t have to worry about being peeked anymore in daily use 4. Tempering treatment adds another layer of protection for daily use. The official display is composed of oleophobic coating, explosion-proof film layer, Japanese AGC material, and silicone coating, which once again enhances the protection of mobile phones.

Magnetic wireless charger:

1. The casual black Magsafe magnetic charging, smooth arc edge, round and smooth, feels good to use, will not scratch your hands, is also very friendly to mobile phones, will not scratch the mobile phone. 2. It’s easy to stick in place, suck it up immediately, charge it up immediately, and quickly replenish energy. Supports up to 15W, which is very convenient for charging mobile phones. 3. The compact body is close to the original thickness, only 5.2mm. The front is a mirrored minimalist design, and there is only a NIILKIN LOGO on the back. Just simple and capable. 4. Over-temperature, over-voltage, short-circuit and over-current protection, as well as metal foreign body detection, which is particularly friendly when charging mobile phones. 5. Compatibility is particularly good. The mobile phone can be charged, and another interesting thing is that it comes out of the main body, it has a C port, and then another C2C cable, and at the same time I gave a small adapter from the C port to the A port. I like this very much. . to sum up: After a whole set, I found that Nelkin’s product idea is really good. It protects mobile phones in place, and then takes into account all aspects, and meticulously solves all aspects of mobile phone use. I personally recommend it

Some foreign technology experts predict the event will take place on August 3, but it is likely that the event will take place later than expected. Some sources from Samsung said that the Korean technology giant is expected to hold an online event called “Galaxy Unpacked” right in August to introduce two Galaxy Z Fold3 smartphone models. and Galaxy Z Flip3 before officially launching these products at the end of the month. At the event, it is likely that Samsung will also unveil the Galaxy Watch 4 smart watch and Galaxy Buds 2 wireless headset. Galaxy S21 FE smartphone alone will not be introduced at this event but may be. to be marketed next September or October. There is currently no confirmed information about Samsung’s upcoming foldable smartphone, but technology experts predict that the Galaxy Z Fold3 will have a camera hidden under the folding screen and support for the S-Pen stylus. . Particularly, the Galaxy Z Flip3 phone is expected to have a larger rear screen, sharing a protective glass layer with a pair of 3 main cameras including 2 wide-angle lenses and 1 super-wide tube on the outside, especially with a camera on the front. in front of the phone hidden under the screen. Both these foldable smartphone products are expected to be lighter in weight and cheaper in price than their predecessors. The Galaxy Watch4 smartwatch is said to use Google’s Wear OS. Samsung has also previously announced that it will develop a smartwatch platform that merges with Google. Meanwhile, the Galaxy Buds 2 are expected to be cheap wireless headphones, but without the option of active noise control. Technology experts say the early launch of these new smartphone models is to fill the gap of the Galaxy Note series, which Samsung is scheduled to launch in August every year. According to market research firm Strategy Analytics, Samsung was ranked as the world’s top smartphone vendor in the first quarter of 2021 after shipping 77 million smartphones, accounting for 23% of the market share. ./.

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.

Specifically, China accounts for 35% of about 38,000 6G-related patents in the world, or 13,449 patents. In second place is the US with the number of patents accounting for 18%. The 6G network is expected to be 100 times faster than 5G. Photo: PhoneArena. While the US and Europe have launched 6G research projects, strengthening cooperation to ensure benefits, CNIPA said that China has “taken advantage of the technology from 5G networks to continue to be at the forefront”. According to CNIPA, the country of billions should cooperate with a number of Japanese and Korean companies such as NEC, Samsung, and Mitsubishi to “reduce dependence on American and European technology” in some important areas of the 6G network. . Although China leads the world in 6G patents, only one Chinese company makes the list of the top 10 6G enterprises in the world. According to the PhoneArena , the three names holding the most 6G patents include NEC, Daewoo Communications and Mitsubishi. In the areas of artificial intelligence (AI) and terahertz of 6G, China accounts for 75% and 40% of patents globally, respectively. Regarding terahertz in 6G networks, the two largest patent holders are the University of Electronic Science and Technology of China, and China University of Metrology. Although it will take many years to perfect, 6G is expected to bring speeds of terabits, 100 times faster than 5G networks, wide coverage from underwater to space. Some applications of 6G such as immersive augmented reality environment, high-fidelity 3D image display. The speed of 6G brings benefits in many future fields, not only for users but also in the military sector, which is why industrialized countries are vying for the top spot in the research race. 6G. In November 2020, Google and Apple joined “The next G Alliance” (The next G Alliance) with the goal of making the US lead the world in the 6G race, reinforcing the long-term development of the company. 5G network. In February, Apple recruited a number of positions specifically related to 6G, the main work included “researching and designing next-generation wireless communication systems (6G) for wireless networks”, “participating in industry, academic forum on 6G”. In February 2019, former US President Donald Trump also mentioned 6G. “I want to have 5G, even 6G in the US as soon as possible. It’s stronger, faster and smarter than today’s standards. American companies have to work if they don’t want to be left behind,” Trump said. on Twitter. China launches first 6G satellite tinh This 6G satellite will be used to test systems for smart cities, environmental protection, disaster prevention and mitigation.

Recently, the team upgraded the technique to power and program the multipoint biostimulator from a single transmitter. Thanks to new research, electrical and computer engineer Kaiyuan Yang and colleagues at the George R. Brown School of Engineering (Rice University) won an award at the Society of Electrical and Electrical Engineers’ Custom Integrated Circuits Conference death (IEEE). The researchers performed experiments showing that an alternating magnetic field can be controlled by a battery-powered generator outside the body. The transmitter can be mounted on a belt or harness, powering and programming two or more implants at least 60 millimeters away. The implant can be programmed with a delay measured in microseconds. That could allow them to coordinate the activation of multiple wireless pacemakers in individual heart chambers, says engineer Yang. “Our study shows that it is possible to program the implants to stimulate in a coordinated pattern. We sync every device, like a symphony. That gives us a lot of scope in stimulant treatments, whether it’s for the heart rhythm or the spinal cord.” The scientists also experimented using small implants. Each tissue is about the size and weight of a vitamin. Experiments performed on hydra vulgaris rodents have demonstrated that, for at least a short distance, such devices can stimulate two separate hydras to contract. Then, activate a fluorescent tag to respond to electrical signals and respond at controlled amplitudes along the rodent’s sciatic nerve. “A study on spinal cord regeneration showed that multipoint stimulation in a certain pattern helps restore the nervous system. Several clinical studies are underway, but all are using desktop devices. There is no implantable tool that can do this,” said engineer Yang. Lab devices, called MagNI (for electromagnetic nerve implantation). MagNI was introduced early last year as a cordless spinal cord stimulator for power and programming. That means the wire does not need to be passed through the patient’s skin. Because, putting the wire through the skin is a method that can cause infection.

It’s easy to set up, secure, and sophisticated enough to find and adjust different power levels to match the needs of any device. Even during use, it continuously charges devices and as a safety measure, reroutes power as needed. Motorola and Guru have not provided much information about this partnership and when phones using remote wireless charging technology will be available to consumers, but the two will work together to meet the requirements. strict requirements on quality, efficiency of electricity use and safety. Earlier this year, Motorola showed off a demo of a device allegedly called the Motorola One Hyper that charges two Moto Edge phones remotely, but didn’t say if it would work with Guru on the project. Remote wireless charging technology has also been researched by many companies since 2015, such as Energous company researched and claimed to be able to charge phones from about 4 meters away. This year, Xiaomi also introduced Mi Air Charging Technology, which in the future can remotely charge multiple devices at the same time.

In their paper in the journal IEEE Trans Transaction on Biomedical Engineering, the team presented the results of trials on two men with spinal cord injury aged 35 and 63. The system works by connecting a signal generator on the user’s head to an electrode relay in the cortex, through the connection port like wired systems. From there, the tester can move, click and type on the computer keyboard with his or her brain. Transmitter connects to a relay located in the brain cortex, helping people to use wireless computers. Photo: BrainGate. In the test, both candidates were able to achieve typing speed and click accuracy on par with a wired system. At the same time, they can use the system continuously for up to 24 hours at home. “The signals are recorded and transmitted with the same fidelity as a wired system, meaning we can use the same decoding algorithms that we have,” said John Simeral, who leads the team. used with conventional wired equipment ”. “The only difference is that we are no longer physically tied to the devices, which opens up new possibilities for future research,” Simeral added. “With this system, we are able to look at brain activity at home, over the long term, in a way that was previously almost impossible,” said Leigh Hochberg, another team member. This gives us more opportunities to create algorithms that allow people with paralysis to move and work. ” According to the Mashable, The aforementioned study is a significant step forward in the field of neural communication, in which the human brain is directly connected to the computer. Recently, big names in the tech world like Facebook and Elon Musk have also expressed interest in this area. Simple device is placed on top of research candidate. Photo: Radiofiji. In 2020, Elon Musk’s startup Neuralink introduced a pig named Gertrude, with a computer chip implanted in the brain. Or, as before, in 2021, the company also succeeds in implanting a chip into the monkey brain so that the animal can play video games. However, Brown University’s first human study demonstrates that the technology can be used wirelessly, and it wouldn’t be surprising if we find wearable devices that allow people with disabilities to communicate with them. continue and work better in the future.

The Sidewalk was announced by Amazon in 2019 and ready to launch in the middle of next month. Photo: Amazon This is a project that Amazon has been researching and developing for years, it was first announced in 2019. Amazon Sidewalk will connect things like yard lights, pet trackers, or sensors on mailboxes. Sidewalk’s aim is to provide wireless infrastructure for these devices by turning Amazon devices like Echo speakers into connection points that any Sidewalk-enabled device can use. Amazon will use Sidewalk’s low-energy bluetooth connections as a home wifi backup network. On the Echo front, Amazon plans to take advantage of Sidewalk’s low-energy Bluetooth connections as a backup network for your home wifi, which means better stability during device setup and Reconnect to the router faster when you update the network name or password.

Super smart city model on 6G infrastructure. Although 5G technology has not even been widely available to users, a fierce race for the 6th generation (also known as 6G) mobile network between the leading countries in technology has begun. head. “FORGET 5G”, US WANT TO GO 6G In theory, the 6G network could be 100 times faster than the maximum speed of 5G and is expected to provide many technological applications that have long been seen as science fiction. Such as real-time holograms, flying taxis, and the ability of the human body and brain to be connected to the Internet. Until now, the race to 6G is increasing, especially between the US and China. There are even more concerns: 6G is so important that it has become an arms race to some extent. In this tech race, the United States will likely hamper Huawei’s 6G ambitions just as it has proven it is capable of hurting Chinese tech firms in the past. 6G has clearly been on the minds of policymakers in both Washington and Beijing. Former President Donald Trump shared on Twitter in early 2019 that he wanted 6G “as soon as possible”. The development of 6G could give America the opportunity to regain its lost position in wireless technology. Vikrant Gandhi, Senior Director of Information and Communication Technology Frost & Sullivan said: “ The United States missed the opportunity to lead the 5G wireless technology, and this time they are determined to focus on 6G development. Competition for the 6G lead will be much fiercer than 5G. It is easy to see that Washington started with the “Telecommunications Industry Solutions Alliance” called ATIS and launched the Next G Alliance in October 2020 to “elevate North American leadership in technology. 6G “. The members of the alliance including tech giants like Apple Inc., AT&T Inc., Qualcomm Inc., Google and Samsung Electronics Co., of course, never had Huawei. According to Bloomberg, China also took the lead by launching a satellite in November last year to test the transmission of 6G. In addition, telecommunications equipment maker ZTE Corp has partnered with China Unicom Hong Kong to develop a new generation of technology; Huawei also has a 6G research center in Canada. However, in this tech race, the US may hamper Huawei’s 6G ambitions as the country has shown it is capable of detrimental to Chinese technology firms in the past. KOREA AND CHINA HAVE ADVANTAGES IN A 6G RACING Samsung Electronics and Huawei Technologies are two leading names in the deployment of BTS stations, which are important infrastructure of telecommunications networks. According to the Nikkei, Korea and China will have an advantage in the 6G technology race. Japan and the US will have difficulty if they want to catch up with these two countries on 6G. Currently, Samsung is leading in 5G copyright, holding 8.9% of the number of copyrights. Huawei came in second with 8.3%, Qualcomm with 7.4%, while Japan’s NTT Docomo came in sixth with 5.5%. South Korea is hoping to become the first to offer commercial 6G services, with corporations Samsung and LG setting up research centers and the government considering investing 976 billion won (18,687 billion dong) in development projects. Beijing also announced its 6G network research and development program last November, and Huawei launched a dedicated research team. According to Tetsuya Kawanishi, telecommunications expert from Waseda University (Japan), BTS stations are expected to change both quality and quantity to be compatible with the 6G network. Japan currently has about 600,000 BTS, but to properly meet the 6G infrastructure, 1 billion stations are needed, while the world will need 100 billion stations. Theoretically, a 6G network can reach more than terabits per second, 10 times faster than 5G. But in terms of coverage, the transmission distance of 6G base stations will be only 200 m or less, and using shorter wavelengths, smaller antennas. Therefore, lighting equipment, signs or passenger cars can also add BTS to increase the coverage. According to HIS Market market research company, three companies including Huawei, Ericsson (Sweden) and Nokia (Finland) account for 80% of the BTS market share and many companies are racing to develop smart stations. to lead the race in this segment. SUPER EXPLOSION 6G NETWORK CONNECTION Four main orientations on connection are being studied by countries around the world, including: smart connection, deep connection, heterogeneous connection and connecting everywhere. Most likely, the technologies of the future are considered to be included in the 6G network such as optical wireless communications, quantum communications, unmanned aerial vehicles, low-rise satellites … Moreover, artificial intelligence and big data analytics are also included in the 6G network support to ensure network quality goals. Most likely, the technologies of the future are considered to be included in the 6G network such as optical wireless communications, quantum communications, unmanned aerial vehicles, low-rise satellites … Since then, many super smart applications based on 6G platforms such as: smart home will be widely deployed when smart devices are able to connect and control remotely; Intelligent traffic with control systems, autonomous vehicles, flying taxis; Smart city is built on environmental monitoring systems, optimal energy control systems to improve people’s living standards. Augmented reality technology also requires a 6G network. In addition to the objects being 3D simulated and controlled by artificial intelligence, the user experience will be supported by all 5 senses of hearing, seeing, smell, taste, and touch through sensors. With high bandwidth speed, low latency, 6G network will ensure the quality of user experience. The wireless communication features of the 6G network allow the technology of tomorrow to be the brain and computer interface system (BCI) in everyday life. BCI takes signals from the brain and sends them to digital devices, analyzing and interpreting the signals into device control commands. Moreover, integrated satellite network will allow 6G network to have global mobile coverage; convert and upgrade conventional connections into smart ones; integrated power and information transmission, not only allowing information transmission but also wireless power transmission to charge devices.

Businesses have difficulty when the Indian government suspends the license to import Wi-Fi devices According to Reuters sources, India delayed the approval of imports of Wi-Fi modules from China for several months. These include complete electronics like Bluetooth speakers, wireless headphones, smartphones, smartwatches, laptops, all of which contain a Wi-Fi module. The Wireless Planning and Coordination Agency (WPC) under the Ministry of Communications of India has suspended the license since November 2020. More than 80 applications from US, Chinese and Korean businesses are waiting. Even records from some domestic companies have the same fate. Tough stance on Chinese imports comes amid Indian Prime Minister Narendra Modi calling for stronger economic self-sufficiency. His policies have helped spur the assembly of smartphones in the country. Reuters sources believe that the latest move by the government to persuade companies to allocate more electronics production in India. However, technology businesses are faced with a difficult situation: production in India requires a large amount of capital and has to wait a long time to be profitable. On the other hand, the government has imposed import barriers that put them at risk of huge losses. In the past, India allowed companies to self-declare wireless equipment, making it easier to import. However, the invitation rule in March 2019 requires them to seek government permission. Although India is already the world’s second-largest mobile phone maker, analysts and technology experts say the country is not of enough scale or scale for big companies to invest. into manufacturing IT products and smart wearables. Watch out for Chinese technology The delay in WPC licensing also represents a strategy to reduce China’s influence on India’s technology industry, especially following last year’s border clash. This week, Modi’s government removed Huawei from the list of companies tested for 5G, while competitors from Europe and South Korea were allowed. Once 5G starts rolling out here, New Delhi is likely to ban carriers from using Huawei equipment. In 2020, US businesses such as Apple, Cisco and Dell will also be stuck in Sino-Indian tensions when Indian ports “detain” imports from China. At the end of 2020, India tightens papers proving the quality of Chinese goods, slowing down the process of importing iPhones. Currently, once they have obtained the proof of quality, they are stuck at another gate, which is the WPC. Du Lam (Reuters)

Earlier this month, Huawei launched a new generation of wireless headphones called FreeBuds 4i, which integrates many notable equipment at a reasonable price, bringing a new experience to the average user. Compared with its predecessor, the product still retains the “in-ear” design with the long tube, characteristic of True Wireless headphones. The long tube section also makes handling easier than current earbuds. Each headset weighs 5.5 grams, does not cause discomfort despite being worn for a long time. Thanks to being equipped with Bluetooth 5.2 connectivity, the headset connects to the phone quite fast and stable. Meanwhile, the earphone box has an egg-shaped design, weighs 36.5 grams, so it is easy to hold and does not create a sense of need when put in the pocket. However, the box’s sleek design also makes it easier to pick up fingerprints than before. The magnet in the box sucks so hard to get the headphones. The highlight of the Huawei FreeBuds 4i compared to its competitors in the segment is its active noise cancellation. Through a long press and hold, users can enable or disable the active noise cancellation (ANC) of the headphones. The Huawei FreeBuds 4i has 2 noise-canceling microphones – one outward, one inward. The noise resistance of this headset model is quite good, when most of the noise is eliminated, such as horns, blowers, voices, … Besides, FreeBuds 4i also has an extra “Recognition” feature. Users can hear ambient sounds without having to remove the headphones or turn off the noise canceling feature. In addition to active noise cancellation, the battery life is also an impressive point of the product. The headset has a usage time of 6 to 7 hours with the noise canceling on, 10 hours when the feature is turned off. The charging box provides an additional 20 hours of use. Huawei also equips FreeBuds 4i with fast charging, giving users about 4 hours of use with 10 minutes of charging. The product is available in 3 color options: black, white and red. Statistics released by Huawei show that during the first sale from March 27 to April 4, 2021, FreeBuds 4i with 2 versions, white porcelain and carbon black, sold 1,000 units. Next, the company statistics as of April 14, 2021 recorded nearly 2,000 FreeBuds 4i products sold. Huawei says these sales have surpassed all of its ever-present records on e-commerce platforms as well as on retail channels. This also partly reflects Vietnamese users who are in great demand for True Wireless wireless headsets at affordable prices, fully equipped with features such as ANC noise cancellation, long battery life. With FreeBuds 4i lava red version, Huawei oriented this color to target young customers who like the highlight and dynamism, in addition to the two previous colors, white porcelain and carbon black for users. system, likes simple.

Wireless electricity does not emit radiation. This picture seems impossible at first glance but is being realized gradually through an idea called “wireless electricity”. From the Tesla coil From 2021, Powerco, New Zealand’s second largest electricity distributor, will work with start-up Emrod to bring wireless electrical technology to life. It all stems from the ambitious dream of the Serbian engineer, Nikola Tesla. Back in 1899, in the city of Colorado Srpings, USA, Nikola Tesla created a 50m high coil with a current of 12 million volts, called the “Tesla coil”. The coil has an activation switch. Just flip the switch, a flash will flash from the coil, carrying wireless current to light up 200 nearby bulbs. During the test, no one was injured. This experiment hypothesizes that the Earth can conduct electricity by itself without the need for a transmission device. And the technology of transmitting electricity in the air can be quite safe for humans or other living things. After that, Nikola Tesla continued to experiment with electromagnetic induction, discovered by scientist Michael Faraday from the 1820s. According to this experiment, around the electromagnet has a changing magnetic field, creating an electric current in a wire is nearby. Electric currents in a wire create electrical energy in the air, which can exist as a magnetic field. From his experiments, he modified and perfected the Tesla coil, the first system to wirelessly transmit electricity. The Tesla coil consists of two parts: a primary coil and a secondary coil. Each coil carries its own capacitor. The two coils and capacitors are connected by an ignition slot and can produce a spark. In general, the Tesla coil is two open circuits connected to an ignition slot. It needs a source of high voltage messages, passed through a transformer to produce thousands of volts. First, the primary coil will be connected to a power source. It will absorb electrical charges like a absorbent sponge. The primary coil is usually made of copper, a material that conducts electricity well, as it must be able to withstand very large charges and many electric waves. When the primary coil’s capacitor has accumulated a lot of charge, it will escape and create a magnetic field. Magnetic energy induces an electric current in the secondary coil. The compressed voltage through the air between the two coils creates a spark in the air. When the charged charge in the capacitor of the secondary coil rises, it will escape in the form of an electric arc. When this happens, an energy is enveloped between the two coils. The high frequency voltage can light fluorescent bulbs a few feet away without the need for a transmitter. Wireless power network infrastructure Inspired by Nikola Tesla’s invention, New Zealand-based Greg Kushnir founded the Emrod Energy Company. The company plans to deploy wireless power infrastructure. To do this, Emrod uses a system consisting of a power source, a special antenna capable of converting radio waves into electricity, called “rectenna,” the base stations. The transmitting antenna converts electricity into microwave particles. In the area using wireless electricity, Emrod installs base stations fitted with square pads. The microwave particles transmitted to the receiver will be gathered into a beam, leading to the rectenna in the area. The rectenna’s job is to convert the microwaves back into electricity. The reason that the receiver is square is because it needs a large surface area, which helps to collect all microwaves passing through. “We have developed a long-range wireless transmission technology,” said Greg Kushimir. The technology itself has been around for a while. Our project is a continuation of Tesla’s achievements ”. However, Kushimir commented that Tesla can generate alternating current from the Tesla coil but he cannot control the electric beam at a long distance. In contrast, Emrod can keep the electric beams tightly connected, stable transmission thanks to two technologies. First, it must be mentioned is the technology related to transmission lines. The microwaves passing through the collimator are converted into a parallel beam of light. Next, Emrod used metamaterials designed in microscopic samples, highly efficient in microwave reception. The Rectenna acts like an invisible cable. Their job is to transmit electricity to the people. By eliminating the traditional wiring, Emrod can bring electricity to areas with difficult terrain, difficult to access because the infrastructure here does not support electricity networks. This technology also has a positive impact on the environment as people do not have to depend on generators that run on gasoline or oil. Power generation stations can also be quickly installed after a natural disaster. Thus, bad weather does not affect the wireless power transmission system. However, Kushimir expressed the challenge now is communication and public orientation. Like the advent of 5G, many people may oppose this idea due to concerns about the negative effects of radiation. But Kushimir asserted, the wave beam transmitted in the new technology does not emit radiation harmful to humans.

After announcing the Xperia 1 III and Xperia 5 III, Sony did not include the price but very quickly, the Sony website in Russia has pre-ordered these 2 machines. Specifically, the Xperia 1 III sells for RUB 99,990 (about $ 1,300) for the standard version of 12GB RAM and 256GB of memory. While Xperia 5 III is priced from RUB 84,990 (about 1,100 USD), this price includes 20% sales tax and will vary from country to country. This price is said to be expensive because the Galaxy S21 Ultra 256GB is only 6% higher than the Xperia 1 III, but it will take until July 20 to get the device while the Galaxy S21 Ultra is always available. However, Sony in Russia will give away the WF-1000XM3 headset for free when customers pre-order the Xperia 1 III and Xperia 5 III. This true wireless headset retails for $ 229, which is not a bad promotion. Xperia 1 III owns 6.5 inch OLED screen, 4K HDR resolution, 120Hz refresh rate. Snapdragon 888 processor, 4,500 mAh battery capacity support 30W fast charging. It has 4 rear cameras including 12MP main camera, 12MP telephoto camera, 12MP super wide-angle camera and ToF sensor. Xperia 5 III is equipped with 6.1 inch OLED screen, FullHD + HDR resolution, 120Hz refresh rate. The remaining parameters such as the camera, processor, battery capacity and IP65 / 68 standard water resistance are the same as the Xperia 1 III. According to Phonearena
