First, preface: 229 yuan! Give consideration to design and performance

In recent years, the popularity of the Internet is really staggering. Not only wireless network, but also the development of home fixed network is almost by leaps and bounds.

When I was in middle school, I still used dial-up Internet access at home. At that time, it took me an hour and a half to download Crossing the Fire Line with less than 1GB. Look at today, even the average family, the broadband speed is above 100M, and it can be satisfied to have 300M or 500M m.

At the same time, the speed-up and fee-reduction of fixed-line network has promoted the development of router industry. Nowadays, almost all mobile phone manufacturers are involved in the router industry, among which Xiaomi router is the largest and the earliest one.

When I was in college a few years ago, I used a certain route of Xiaomi in my dormitory. However, although Xiaomi mobile phone was very hot at that time, the attention of router accessories was not very high because the Mijia ecological chain had not yet appeared.

Today, the author took a look at an online mall. Xiaomi has sold more than 1 million routers, and the sales of other routers are also hundreds of thousands.

With such a large volume and so many years of technical accumulation, Xiaomi is no longer constrained by the traditional router development model, and some recent routing products basically bring some creativity and new ideas in function or appearance.

For example, Xiaomi Routing Mesh released at the beginning of this year can realize 3-channel hybrid networking of 2.4G WiFi, 5G WiFi and power line. Another example is Xiaomi Router HD, which is designed with all-metal body and equipped with 1TB HD streaming media hard disk.

Of course, due to the positioning of these two products, the price is not acceptable to all consumers (1299 yuan /999 yuan). Perhaps it is in view of this situation that the product we want to evaluate today — — Xiaomi router AC2100.

It is worth noting that its price is only 229 yuan, so what will happen to Xiaomi router AC2100? Let’s start today’s evaluation.

Second, appearance: minimalist cylindrical design, ventilation and super heat dissipation.

↑ ↑ ↑ Xiaomi routing AC2100 packaging box

↑ ↑ ↑ The specific information of the router is printed on the box.

↑ ↑ ↑ Xiaomi routing AC2100 fuselage front, using a minimalist design.

If you look closely, you can see that there are two indicator lights at the lower slot, namely the network status light and the system indicator light.

The black cylindrical shape gives people a heavy feeling, but it feels completely different in the hand. The whole plastic material makes its actual weight only 620 grams. Because there is a gap inside the router, the shell of the router will hear the empty echo when it is knocked.

↑ ↑ ↑On the back of the router, from top to bottom, there are four network cable sockets, power interface and reset key respectively.

There is only a minimalist Xiaomi Logo on the top of the router, and there is a circle of cooling holes on the periphery.

The cooling holes at the bottom echo with the top to form a chimney-type heat dissipation, and the heat dissipation efficiency will be higher by going straight up and down. In addition, the gray circle at the center is non-slip rubber.

↑ ↑ ↑ Fuselage details

Xiaomi routing AC2100 also comes with a gigabit network cable, which is very conscience.

↑ ↑ ↑ The standard power adapter of the router has an output of 12V/1A.

Third, signal strength: 200㎡ super-large space full coverage.

Xiaomi router AC2100 does not display the two signal bands of 2.4GHz and 5GHz by default like most routers now, but displays them separately. (as shown below)

After the router network is set up, it will provide two frequency bands, 2.4GHz and 5GHz, and mobile phones can be connected separately.

The advantage of this is that the two do not interfere with each other. When connected to 2.4GHz, the wall penetration performance is better and the coverage is farther; When connecting the 5GHz band, under the 802.11ac technology, the interference will be smaller and the speed will be higher, which is suitable for watching high-definition videos and playing large games.

If you are used to the combined display of 2.4GHz and 5GHz, the dual-frequency terminal can automatically select the optimal frequency band, and this function can be turned on in the Wed management background.

— — Signal strength test

In daily use of wireless routers, we pay most attention to the signal strength, which directly determines the user’s experience.

We usually use Wi-Fi at home. Under normal circumstances, the signal strength is 60dBm to 80dBm, which can meet the daily use of surfing the Internet and browsing video music. It can be stable above 60dBm, and there are few jams when playing games.

When large files need to be transferred, the requirements are slightly higher, and the dBm value should be above 40.

We tested the signal strength of Xiaomi routing AC2100 this time, which imitated the daily home environment. The wireless router was placed next to the TV in the living room, and three rooms with different distances were selected as test locations.

Here, the author chooses a house of about 100 square meters and a Xiaomi MIX3 as the Wi-Fi signal testing equipment.

↑ ↑ ↑ Schematic diagram of house type, with points A, B and C as test positions.

Let’s look at the test results:

The above picture shows the signal strength measured by Xiaomi MIX3 at positions A, B and C respectively.

The average signal strength of test point A is -23dBm, and the WiFi connection rate is stable.

The average signal strength at point B is -48dBm, and the signal is weakened by one grid.

The average signal strength at point C is -68dBm, and there is one grid of WiFi signal.

Judging from the test data of the above three points, the test range of 100㎡ in the author’s home is obviously not enough. After all, Xiaomi AC2100 mainly focuses on the large apartment of 200㎡!

After that, the author chose the further elevator D. At this time, the mobile phone began to choose to connect to the 2.4GHz band. Under the 2.4GHz network, the average signal strength measured here is acceptable, which is -70dBm, but the average delay is over 300ms, so it is absolutely impossible to play games at this distance.

— — Transmission rate test

For a router, in addition to signal strength and coverage, transmission rate is also an important link that has to be considered.

In order to have a deeper understanding of the transmission rate of Xiaomi routing AC2100, the author still tests under the same test link and conditions.

The test software is "Speedtest", which is a professional APP for testing the signal transmission speed on mobile phones. It can detect and calculate the download speed and upload speed.

From the test results of our 300M Unicom broadband, the actual download speed reached 332Mbps and the upload speed reached 33.4Mbps without partition, and the best performance of my home routing was basically the same.

At point C, which separates the two walls, its download speed can still be maintained at 169Mbps.

Judging from the actual test results, Xiaomi routing AC2100′ s wall penetration ability and network effect are satisfactory. According to the official data, Xiaomi Routing AC2100 can connect up to 128 devices, so in addition to family use, small and micro enterprises with more members can fully meet the demand.

V. Power consumption test: the peak value does not exceed 5W, and the power consumption lasts for ten days!

Although the power consumption of routers can’t be compared with that of household appliances, we hardly choose to turn it off in daily life, and the accumulated power consumption can’t be underestimated.

We tested the Xiaomi routing AC2100 with a power consumption tester. When four mobile phones are connected, the power consumption of Xiaomi routing AC2100 is about 4.7W.

According to the full-load power conversion of 4.7W, it takes 213 hours, or about 9 days, for Xiaomi to consume one degree of electricity through AC2100. That is to say, under the condition of full load for 24 hours, 1 degree of electricity can be used for nearly 10 days.

Sixth, summary: 100 yuan to 1,000 yuan high school low price full coverage.

All students who have used Xiaomi routing know that one of the advantages of Xiaomi routing is the linkage with Xiaomi smart home devices.

We have also said that many people, even if they are not Xiaomi mobile phone users, must have used the products of Mijia Eco-chain more or less. Just like the author, unconsciously, there are not only Mijia electric toothbrush at home, but also Mijia weighing scale, smart desk lamp, and so on.

Usually, mobile phones are often used to manipulate these devices. In the past few days, when using Xiaomi to route AC2100, the author also found a very useful small function, that is, when modifying the WiFi password through Xiaomi WIFI APP, the router will automatically synchronize to Xiaomi smart home devices at home. Although this function sounds simple, it is absolutely necessary for students who have multiple Xiaomi smart devices at home.

Xiaomi routing AC2100 also has some practical functions, such as Netease UU accelerator, anti-rubbing network, red envelope Wi-Fi, etc. We have seen most of them before, so I won’t repeat them here.

— — finally

When evaluating millet products, especially non-mobile phone products, we can’t avoid the price.

The price of Xiaomi router AC2100 is 229 yuan, and its positioning is closer to that of Xiaomi router Pro(449 yuan), both of which are advanced routers with high cost performance, taking into account avant-garde design and good performance.

The significance of the sale of Xiaomi router AC2100 is that Xiaomi router has completed the full coverage of high, medium and low prices from less than 100 yuan to more than 1,000 yuan.

If you want to choose an entry-level router, 59 yuan Xiaomi router 4C and 99 yuan Xiaomi router 4A can be selected.

If you have a big room at home, you can choose 999 yuan Xiaomi router Mesh or 1299 yuan Xiaomi router HD, with exquisite shell and super performance. Friends who have special needs for network storage will definitely like it.

　　[Talking about health]

　　Love of beauty is nature, and health and safety are the premise. Recently, the basic laws and regulations of China’s cosmetics industry have ushered in major changes in the past 30 years — — The Regulations on Cosmetic Supervision and Management was officially issued by the State Council, and the Regulations on Cosmetic Hygiene Supervision, which has been implemented for 30 years, withdrew from the historical stage.

　　In November 1989, China issued the Regulations on Hygienic Supervision of Cosmetics, which came into effect on January 1, 1990. Over the past 30 years, China has developed into the second largest cosmetics market in the world, with more than 5,200 cosmetics manufacturers. However, the rapid development has also brought some problems, such as illegal addition of banned substances, fake and inferior products, and safety of raw materials, which have hidden health concerns under the beautiful appearance. What changes will the new regulations, which will come into effect on January 1, 2021, bring to the cosmetics industry? How to make our beautiful career healthier? The public is full of expectations.

　　As a chemical industrial product that directly acts on human body, cosmetics bring us beauty, and at the same time, health and safety must be guaranteed. Only when you have health can you talk about beauty. However, some unhealthy phenomena in China’s cosmetics industry have brought hidden dangers to the health of beauty lovers — —

　　Illegal addition of prohibited substances that may be harmful to health, unauthorized preparation of cosmetics by beauty salons, fake and inferior products counterfeit well-known brand products, false publicity and even claims of medical functions, and emphasis on packaging and publicity rather than technological innovation … …

　　We want to be beautiful and healthy and safe. A few days ago, the "Regulations on the Supervision and Administration of Cosmetics", which received much attention, was officially promulgated. This also means that the "Regulations on Hygienic Supervision of Cosmetics", which has been implemented for 30 years, will end its historical mission. The new regulations not only adapt to the new situation, but also solve old problems. Among them, there are many highlights worthy of attention.

　　Highlight 1: Intensify the crackdown on "grey areas", and illegally adding prohibited substances can be fined up to 30 times the value of the goods.

　　In recent years, with the rapid development of China’s cosmetics industry, illegal addition and other illegal phenomena are more prominent. In the first half of this year, National Medical Products Administration issued a number of notices about problematic cosmetics. Most of these notified cosmetics are counterfeit or detected prohibited substances. According to media reports, some inferior cosmetics counterfeit well-known brands, or improve short-term effects by adding banned substances such as hormones, which have become "hidden rules" and "gray areas" of the industry.

　　In 2018, Taizhou City, Jiangsu Province investigated and dealt with a case of illegal addition of prohibited ingredients to extra-large cosmetics. Illegal people buy cosmetics raw materials with illegal banned ingredients from multiple channels, or add a large number of banned ingredients such as betamethasone, mercuric chloride, metronidazole and chloramphenicol to facial masks, whitening and acne-removing cosmetics, and sell them to thousands of beauty salons, cosmetics stores and tens of thousands of consumers in more than 20 provinces across the country through semi-finished products, branded products and finished products. Local regulators said that the case profoundly exposed the long-standing "hidden rules" of the cosmetics industry.

　　Compared with the old regulations 30 years ago, the new regulations have intensified the crackdown on various illegal acts and enhanced the deterrent power of the law. Yang Zhanxin, deputy director of the Comprehensive Planning Department of Hebei Provincial Market Supervision Administration, noticed that there are 18 articles on punishment for illegal acts in the new regulations, which is twice as many as the old regulations; The content of the law is also more detailed, covering all kinds of illegal situations.

　　"The new regulations combine the law enforcement practice in the past 30 years and the outstanding problems in the current cosmetics market. Anyone who sets prohibitive provisions and compulsory provisions for producers and operators has set legal responsibilities in the legal responsibility part." Yang Zhanxin pointed out.

　　The new regulations comprehensively use punishment measures such as confiscation, fine, order to stop production and business, revocation of licenses, and market and industry bans to crack down on illegal activities. Take fines as an example. In the past, the base of fines was "illegal income", but now it is adjusted to "value of goods", and the amount of fines has been greatly increased. For example, in the case of illegal activities such as engaging in cosmetics production without permission, from the old regulations, "a fine of 3 to 5 times the illegal income can be imposed" to "a fine of more than 15 times and less than 30 times the value of the goods".

　　Moreover, the provisions on "punishing people" for illegal acts have been added. The legal representative or principal responsible person, the directly responsible person in charge and other directly responsible personnel of a serious illegal unit shall not only be fined, but also be prohibited from engaging in cosmetics production and business activities for life.

　　For example, in cracking down on counterfeiting and illegal addition, the new regulations make a series of new provisions: cosmetics producers and operators are required to establish and implement a record system for incoming goods to ensure the traceability of products; For illegal acts such as illegally adding substances that may endanger human health, a maximum fine of 30 times the value of the goods can be imposed, and even cosmetics production and business activities can be banned for life. The new regulations also provide clear penalties for behaviors such as making cosmetics and changing the use period of cosmetics without authorization by beauty salons and hotels that were not clearly defined in the old regulations.

　　In addition, the new regulations also emphasize that the regulatory authorities can take emergency control measures to order the suspension of production and operation and issue safety warning information for cosmetics that cause human injury or have evidence that may endanger human health.

　　"This gives the so-called ‘ Grey zone ’ It sounded the alarm. " Professor Dong Yinmao of Beijing Technology and Business University said in an interview with the media.

　　Highlight 2: "Let good steel be used on the blade" to ensure the safety of cosmetic raw materials more scientifically.

　　According to the new regulations, cosmetics refer to daily chemical industrial products that are applied to human surfaces such as skin, hair, nails and lips by rubbing, spraying or other similar methods for cleaning, protecting, beautifying and modifying. As a chemical industrial product directly acting on human body, safety is the bottom line of cosmetics. In addition to illegally adding prohibited substances, if there are problems with the raw materials of cosmetics themselves, it will also bring hidden dangers to the health and safety of consumers. Safety of raw materials is an important prerequisite for the safety of cosmetics.

　　"Generally speaking, cosmetics are a mixture made of a variety of raw materials according to the formula ratio, and most of this preparation is a physical mixing process, and few chemical reactions are involved. Therefore, the safety and function of raw materials directly affect the safety and performance of finished cosmetics. " Xu Liang, member of National Medical Products Administration Cosmetic Standards Expert Committee, explained.

　　Compared with the old regulations, an important change in the new regulations is to emphasize risk management, that is, to implement different levels of classified management according to the level of security risks. Preservatives, sunscreens, colorants, hair dyes, freckle-removing and whitening agents and other high-risk new raw materials must be registered with the drug supervision and administration department of the State Council before they can be used. Other new raw materials only need to be put on record.

　　Moreover, there is also a "safety assessment period" for new raw materials — — Within 3 years after the new raw materials for cosmetics are put into use, the registrant and the record holder of the new raw materials shall report the use and safety of the new raw materials to the drug supervision and administration department of the State Council every year. If there are security problems, the registration will be cancelled or the record will be cancelled. No safety problems occurred after the expiration of 3 years, and it was included in the list of used cosmetic raw materials formulated by the drug supervision and administration department of the State Council.

　　The new regulations also stipulate that, according to the development of scientific research, if there is a change in understanding of the safety of cosmetics and cosmetic raw materials, or there is evidence that cosmetics and cosmetic raw materials may be defective, the regulatory authorities may order the registrants and filers of cosmetics or new cosmetic raw materials to carry out safety re-evaluation or directly organize safety re-evaluation. Re-evaluation results show that cosmetics or cosmetic raw materials can not guarantee safety, the registration or filing shall be cancelled, and the regulatory authorities shall include them in the list of raw materials prohibited from being used in cosmetics production and announce them to the public.

　　It is worth noting that the new regulations require the establishment of a cosmetic risk monitoring and evaluation system to monitor and evaluate the risk factors affecting the quality and safety of cosmetics. Song Hualin, a professor at Nankai University Law School, believes that through risk monitoring and evaluation, judging the risks contained in cosmetic raw materials, products, production and operation processes and labels, we can have an overall grasp of the safety situation of cosmetics and understand the main problems existing in the safety and quality of cosmetics.

　　Knowing where there are problems can better carry out targeted supervision. The new regulations point out that risk monitoring provides a scientific basis for formulating risk control measures and standards for cosmetic quality and safety and carrying out cosmetic sampling inspection. Moreover, the national cosmetic safety risk monitoring plan is implemented, and the varieties, projects and regions to be monitored are clearly defined. Song Hualin believes that this can "let good steel be used in the cutting edge" and allocate risk supervision resources more scientifically and reasonably.

　　Highlight 3: Encourage the technical innovation of cosmetics, and give the products with new functions a broad space for development.

　　In fact, classified management is not only conducive to safety supervision, but also conducive to the innovation of cosmetic technology.

　　The domestic cosmetics industry has been criticized for its lack of technological innovation in product efficacy. Without innovation, we can only make a fuss about packaging such as advertising. In Xu Liang’s view, many cosmetics companies don’t work hard on technology, but attract consumers by "arranging stories".

　　Xu Liang analyzed that according to the composition characteristics of cosmetics, the innovation of cosmetics mainly depends on the innovation of raw materials, especially the development and innovation of functional raw materials and raw materials that contribute to the improvement of cosmetic dosage forms. However, in the old regulations, new cosmetic raw materials were registered and managed as a whole, and the evaluation scale was not refined in combination with the characteristics of cosmetic raw materials. Enterprises declared a new raw material, "even if it is only a polymer with no skin penetration ability or edible common vegetable oil, it often needs to supplement the information many times, resulting in the average time for the declaration of new raw materials being several years".

　　"On the one hand, the enthusiasm of enterprises to declare new raw materials is affected. On the other hand, new raw materials that have been proved to have good performance and are widely used in the world cannot be used in Chinese cosmetics, which has also increased the gap between Chinese cosmetics and foreign companies in technology and innovation to some extent." He said that the cosmetics update cycle is fast, which requires enterprises to continuously introduce new products to the market.

　　According to the new regulations, ordinary new raw materials for cosmetics are put on record, which simplifies the use procedure. Dong Yinmao believes that the new regulations have changed the long-standing difficulty in approving new raw materials. The establishment of the new raw material filing mode has opened up a brand-new mode for enterprises to innovate and develop new raw materials, and given a broad space for innovation and development of products with new functions.

　　The new regulations encourage the innovation of cosmetics enterprises not only in the management of new raw materials, but also clearly put forward that the state encourages and supports the research and innovation of cosmetics; Encourage and support the use of modern technology, combined with China’s traditional advantageous projects and characteristic plant resources to research and develop cosmetics.

　　Xu Liang believes that this is good for the healthy development of the whole industry, because "one has no technical strength and only passed ‘ Arrange a story ’ Companies that attract consumers will not do it for a long time. " Dong Yinmao also believes that the new regulations "make enterprises committed to the research of cosmetic raw materials, production technology and product innovation see hope".

　　Highlight 4: Cosmetic efficacy claims must have scientific basis and accept social supervision.

　　Innovation is not enough, and propaganda is coming together. It is not uncommon to make false and exaggerated propaganda on the efficacy of cosmetics and mislead consumers. Some cosmetic practitioners even have the idea of drugs, promoting cosmetics as magical products with medical effects.

　　According to media reports, in January this year, on the train from Rizhao, Shandong Province to Jinan, someone sold a cosmetic called "Baicao Cream" as a medicine to passengers. The salesman claimed that the product can relax muscles and promote blood circulation, relieve pain, and also treat skin diseases, mosquito bites and other symptoms, describing this cosmetic as magical.

　　A few years ago, the concept of "cosmeceuticals" was very popular in China. Cosmetics are next to drugs, as if the efficacy of the products is more guaranteed. However, in January 2019, National Medical Products Administration clearly pointed out that it is illegal to claim the concepts of "cosmeceuticals" such as "cosmeceuticals" and "medical skin care products" for products registered or filed in the name of cosmetics.

　　The new regulations issued this time further clarify the false propaganda behaviors such as claiming medical functions. The new regulations clearly point out that cosmetics labels and advertisements must not express or imply that products have medical functions, and must not contain false or misleading contents.

　　Moreover, the new regulations stipulate that the efficacy claims of cosmetics should have sufficient scientific basis, and the literature and research data on which the efficacy claims are based should be published and accepted by the society. In other words, whether cosmetics are effective and why they are effective must rely on science.
