Smart wearable, also called wearable devices, there are four main features: 1, wear comfortable or even senseless; 2, the use of the process should not interfere with normal life; 3, the appearance should be suitable for the use of occasions and environments; 4, lightweight, wireless is the most basic requirements.
Now there are a lot of smart wearable products, there are smart glasses, smart bracelets, cervical rings, brain rings, beauty eye masks, baby pajamas and so on, which are more widely used in the field of health.
In the Internet era, Wi-Fi is as ubiquitous as the oxygen in our lives. It is the most widely used wireless network transmission protocol today, carrying more than half of the world's traffic, and Wi-Fi is an all-encompassing term used to describe the evolving 802.11 family of protocols.
And the Wi-Fi Alliance, the organization driving the development of Wi-Fi, has simplified Wi-Fi names through numerical nomenclature, such as Wi-Fi6 corresponding to 802.11ax, Wi-Fi5 for 802.11ac, and Wi-Fi4 for 802.11n.
The arrival of 5G opens up the era of the Internet of Everything, like autonomous driving, smart city, remote medical care, smart wearable, etc., are all application scenarios of IoT. In order to better meet the needs of this type of market, the Wi-Fi Alliance has introduced the Wi-FiHaLow certification program, which provides a wider coverage distance and lower power consumption.
Wi-FiHaLow is a certification standard based on IEEE802.11ah technology, and is also a low-power Wi-Fi technology tailored for the IoT market.
As we all know, low-power transmission standards for IoT also include ZigBee, Z-Wave, Bluetooth, and Thread. the drawbacks of ZigBee and Z-Wave are their lower bandwidths, and both are less resilient when it comes to setup. ZigBee, for example, is not capable of frequency hopping, which makes it susceptible to interference during network deployment. Therefore, ZigBee is not suitable for IoT or M2M applications (industry-specific terminals) where the RF environment is unstable. Wi-FiHaLow, on the other hand, can connect up to more than 8,000 devices in a single node, and also has a certain level of anti-interference capability and wall penetration.
As for Bluetooth, its drawback lies in the communication distance, which is usually no more than 10 meters. Wi-FiHaLow, on the other hand, has a maximum transmission distance of 1,000 meters.
As a kind of long-distance wireless transmission technology, Wi-FiHaLow's low-power consumption and long-distance characteristics, in addition to industrial IoT, drones, security monitoring and other fields, can also be used for smart wearable devices.
Currently, mainstream smart wearable devices can be roughly categorized into three main types: TWS, smart watches and smart glasses. The first is TWS, and consumers usually care more about the sound quality, noise reduction, and range of the headphones before they buy TWS headphones.
For better portability, TWS headphones are basically made smaller, about the size of a thumb. With the limited size, TWS headphones need to cram a lot of components inside, including audio units, noise-canceling chips, batteries, and so on.
Now, the vast majority of TWS headphones on the market can basically reach 5~8 hours of single-use time. To further improve the battery life of TWS headphones, manufacturers have two approaches: one is to increase the battery capacity; the other is to introduce fast charging technology.
While it's not difficult to increase battery capacity, there are many problems with this simple and brutal method, such as with the increase in battery capacity, the volume of the battery will also increase, which will also make the headset cavity part of the headset larger and heavier, which not only sacrifices some of the portability attributes, but also affects the headset's wearing comfort. Moreover, adding more features to the TWS will also speed up the rate of battery consumption.
As for the introduction of fast charging technology, it doesn't fundamentally solve the problem of TWS headphones' battery life, as users need to put the headphones into the charging case and wait for 5 minutes before they can continue to use them for another hour. The Wi-FiHaLow low-power feature helps to improve the battery life of the TWS headphones, and although it's not hard to bring a qualitative improvement, at the very least, it's a bit better than before.
Second is the smartwatch. AppleWatch, for example, can operate independently from a cell phone through the e-SIM function, and has a dedicated app store where users can download apps according to their own needs, which can't be done without mobile cellular data and Wi-Fi.
The biggest bottleneck of traditional Wi-Fi is the problem of power consumption, which is the biggest problem of Wi-FiHaLow.
Wi-FiHaLow's performance in terms of power consumption, due to the use of 700~900 lower frequency, as well as narrower channel occupancy width, so that the power consumption and Bluetooth, ZigBee and other short-range wireless transmission technology is on the same level.
That is to say, whether you are downloading and installing apps or using apps that require internet connection for a long time, smartwatches that support the Wi-FiHaLow standard will have a lower power consumption performance, which corresponds to an increase in battery life.
Lastly, smart glasses. Now, the more common smart glasses on the market have two types for home or outdoor use, the former is mainly used for audio-visual entertainment, such as watching movies, playing games, etc.; the latter is more inclined to receive calls and listen to songs.
And Wi-FiHaLow supports long-distance transmission, multi-device connectivity, better wall penetration, and stronger anti-interference, in addition to its low-power features. For home-based smart glasses, if the router is located in the living room, the WiFi connectivity will deteriorate when you use it in the room. Plus if you're not the only one in the house and the router doesn't support Wi-Fi6, using smart glasses may affect the user experience due to network congestion issues. If home-based smart glasses support the Wi-FiHaLow standard, all of the above problems might be solved.
For outdoor smart glasses like Huawei's Eyewear, the biggest problem is the stability of the network connection. For example, when using outdoor-type smart glasses to listen to songs in application scenarios with complex signals such as subways and public transportation, the device may be interfered by external signals, resulting in frequent disconnections. Compared with traditional Wi-Fi and Bluetooth, Wi-FiHaLow has a stronger signal anti-interference ability, which can significantly reduce the interfering nature of external signals on smart glasses.
In fact, compared to smart wearables, Wi-FiHaLow is more useful in laying out the AIoT market. For example, smart security, due to Wi-FiHaLow maximum transmission distance of 1,000 meters, and support for up to 10,000 devices at the same time access to the same connection point, large shopping malls only need to build a Wi-FiHaLow access point in one location, you can cover all the monitoring cameras within one kilometer to support the standard. For merchants, the layout of security monitoring costs will be lower.
And Wi-FiHaLow helps to improve the smart home experience. At this stage of the smart home, the experience is not too good, either often disconnected, or by other devices in the home signal interference, resulting in high latency for actual use. If the smart home all support Wi-FiHaLow standard, then these problems may be solved.
In fact, Wi-FiHaLow is not a new technology, as early as 2016, the Wi-Fi Alliance has announced this standard, just no manufacturers are willing to follow up, until the domestic Zhuhai Taixin Semiconductor launched the world's first production chip based on the Wi-FiHalow standard, but the application scenarios do not have much to do with the average consumer.
To be honest, Wi-FiHaLow in the positioning, and Wi-Fi6 more or less overlap, after all, the indoor application scenarios, the difference is not big. In contrast, Wi-FiHaLow is more suitable for outdoor scenes. It's clear that the Wi-Fi Alliance made the right decision to announce the standard again at this point in time.
However, given the previous progression of the standard from announcement to chip mass production to commercialization, vendors may not have followed through and launched related products as much. Although the Wi-Fi Alliance to join a number of manufacturers, including upstream chip makers Intel, Qualcomm, etc., downstream terminal brand manufacturers, including Microsoft, Apple, Huawei, etc., but the Wi-FiHaLow standard will be applied to the field of smart wearable, ultimately depends on the manufacturers are willing to, after all, there has been a "lesson learned "

Huawei Hongmeng system driverless technology in the world's most advanced, you will buy this kind of car?
Huawei's driverless technology is still very powerful, watched that video, ten minutes down the hand did not touch the steering wheel, in the alley encountered a sudden burst out of the electric car and pedestrians also did not have an accident, and the old driver is no different.
But if this technology is installed on a production model, I'll probably buy it and experience it, but I certainly won't dare to drive with driverless technology. There are a few reasons for this:
1. Driverless technology relies on map data. Although the Huawei driverless video looks awesome, but the car is so familiar with the road, mainly because of the map data entered beforehand, where there are red lights, the realization of the dotted line on the ground, the width of the road and so on a number of columns of information, have been entered into the computer. Driverless just follow the existing map, although the cars and pedestrians on the road appear in real time, but with the Kirin 990A's computing power, as well as a few laser sensors on the car, it can be completely coped with.
But on the flip side, it would be impossible to make this car so perfectly driverless if you drove it to a completely new city. So if this technology can only be used in a limited number of cities, then the utility is greatly diminished.
2, driverless liability issues to be recognized. Driverless the biggest change is the power to drive the car to the computer, although from the Huawei driverless video, this technology has been very advanced, but the complexity of the road conditions in modern cities, sometimes even if you keep careful driving, it is inevitable that accidents will occur. In case of an accident, is the responsibility on the vehicle owner or the computer? From a common sense point of view, the responsibility for vehicle accidents must be attributed to the person sitting in the driver's seat, but if this really happens, the driver will certainly feel innocent, and some people will feel that if they are driving, they may be able to avoid accidents, thus casting doubt on the reliability of driverless.
So existing driverless cars must be equipped with a safety officer during road tests to ensure safe driving. And in many cases, because the safety officer must remain mentally focused at all times, he or she will instead find the driverless more tiring than driving the car themselves.
3, driverless also involves ethical and moral issues. In some special driving scenarios, sometimes it is impossible to avoid accidents. For example, on the highway in front of the fog, and suddenly encountered road blockage, in the case of can't brake in time, there is a school bus carrying students in front, and a truck carrying goods. If in the must tailgate and have a choice, the human driver will certainly choose to tailgate the truck, but if left to the judgment of the driverless, the result is difficult to speculate.
Overall, driverlessness is still a very immature technology, and it can only be used as a demonstration of a technology that can't be practically applied in everyday driving situations. Of course, driverless technology is still useful in some aspects, for example, many cars are now equipped with automatic braking, which is also based on the principle of using sensors to determine the distance of the object in front of you, and to operate instead of braking in case the driver doesn't brake in time. Some of them can also actively avoid sideways incoming traffic and recognize traffic signs. So the prospect of driverless is still very broad.
Huawei Hongmeng operating system driverless technology is the world's most advanced automatic driving system, I buy a car, I definitely prefer this kind of car.
Huawei and BAIC New Energy Automobile on April 17, officially released the first ARCFOX (Extreme Fox) brand driverless car _ "Extreme Fox Alpha S Huawei HI version", the ordinary plate 388,900 yuan, 429,900 yuan of advanced plate.

If the current car change, you can consider
What smart wearable devices are worth recommending, and what are the advantages and disadvantages of each

What technologies are used in the intelligent upgrade of Vanguard AN***HEALTH EV?
The main use of visual AI recognition technology combined with the intelligent central control system to detect whether the rider has a fixed-point directional parking and return, standardize the wearing of safety helmets, and whether there are violations of people, and guide the rider to safe and standardized riding, to crack the management problem of the operator of the **** enjoyment of the e-bike.
What are the advantages of smart wearable devices?
Wearable devices, i.e., a portable device that is worn directly on the body, or integrated into the user's clothing, or accessories.
Intelligent wearable devices, is the application of wearable technology for daily wear intelligent design, development of wearable devices in general. Such as glasses, gloves, watches, clothing and shoes and so on. Mainly combined with the Internet of Things, cloud computing, with the Internet era to follow the development trend, to create intelligent, commoditized wearable devices, now just like the new century, "favorite".
In summary, there are four major advantages:
One, wearable devices are more convenient to operate. Like a smartphone compared to the PC can be more portable, wearable smart devices compared to other mobile devices is not only more portable, in the use of more convenient, it can almost completely rely on the body's natural movements to achieve the operation, such as through the blink of an eye to take a picture, waving the hand to open the recording and so on. This is obviously more enticing than holding your hands to the device buttons, swiping, flipping through menus, and searching.
Two, wearable devices are carried 24 hours a day. Although smartphones are popular, it is always impossible to hold at night to sleep, but watches, wristbands and other wearable devices can be. Of course, holding and sleeping is not considered an advantage, however, the ability to carry characteristics around the clock is conducive to the convenience of continuous health or medical monitoring of the user. In addition, through the skin vibration for silent sleep wake-up, etc. 24 hours a day, close to the characteristics of the wearable device is not easy to be stolen or lost.
Third, wearables are more beautiful and stylish. Many people buy iPhone 5, because of the fashion is beautiful to be attracted, rather than take into account the powerful features, and even some purely for the vanity of showing off to meet, the real use of the function is still limited to call and send text messages to chat, less use of other software. I believe that the future production of smart necklaces, smart earrings or smart bracelets, better than no practical use of jewelry. Naturally do not rule out the use of jewelry, gold and diamonds inlaid wearable devices, which is the first choice to show off the rich.
Four, wearable devices to enhance human capabilities. With the rapid development of cloud computing, wearable devices to bring the user's computing power will be extremely powerful. As wearable devices are almost integrated with the human body, the powerful computing ability brought by them is like a birthright, just like every human being has superpowers. It is not difficult to imagine: do not need to open the phone, open the browser, blink your eyes, you will be able to know tomorrow's weather; sweep a glance at the English newspaper, you can appear in the instant translation of the results; standing outside the shopping malls, see if there are merchants in the discounts; sitting in the car, you can see ten kilometers away from the road conditions of course, there are many other advantages, the ofweek wearable device network hope to adopt
