Smart wearable devices are not new, especially driven by the low price strategy of a certain meter. The early curiosity has been transformed into a substantial purchase. But with the increasing number of users using the device, I found that many of my friends are not very clear about how to maximize their smart value, and some of the small partners even went into the wrong zone. Below, I will summarize the four common misunderstandings of using wearable devices. Come and see if you are recruited.
Myth #1: Going 10,000 steps to lose weight will succeed!
Positive solution: exercise is not enough aerobic exercise!
Most of the smart bracelets on the market mainly feature sports and fitness functions. Through the built-in multi-axis sensor (three-axis, four-axis, six-axis, etc.), the bracelet can identify the user's motion state and record the motion data. Users can adjust their personal habits based on stored data to achieve the ultimate goal.
It is reasonable to say that there is nothing wrong with this, but in real life, I found many friends around me that they think that as long as they have walked 10,000 steps today, the amount of exercise is enough. But scientific research shows that walking alone can't help us achieve fitness or weight loss. Only by doing aerobic exercise can we really achieve our goals.
Aerobic exercise
First of all, give everyone a little knowledge of science. What is aerobic exercise? Aerobic exercise refers to physical exercise performed by the human body with sufficient oxygen supply. The measure of aerobic exercise is the amount of exercise in which the heart rate is maintained at an appropriate value. Common ways of exercising include walking fast, walking slowly, swimming long distances, cycling, etc. That is to say, only walking with a heart rate at an appropriate value is considered aerobic exercise. (Appropriate heart rate appropriate formula: for the general population. Target heart rate = (220-age) * (60% - 80%) 60% -70% of which is mainly used for fat loss; 70% - 80% is mainly used to improve cardiopulmonary function )
Treadmill exercise
So what are the benefits of aerobic exercise? Scientific research shows that aerobic exercise can increase the amount of hemoglobin in the body, improve the body's resistance, improve the working efficiency of the cerebral cortex and cardiopulmonary function, and the fitness effect is remarkable. For people who are losing weight, a reasonable diet plus aerobic exercise, weight loss will be more effective.
It can be seen that even if you walk 10,000 steps or 20,000 steps every day, you may not be able to achieve fitness and weight loss. Targeted aerobic exercise, and then use the monitoring function of smart wearable devices to assist, in order to achieve twice the result with half the effort. This not only realizes the value of smart devices, but also fulfills our goals.
Myth 2: Is the smart device only GPS?
Positive solution: GPS, A-GPS, base station positioning, Wifi positioning multiple positioning combined method
Away from the children around the parents, the friends who are exploring the outside, they have a common need, that is, accurate positioning. Precise positioning means that personal safety is guaranteed and the danger of unknowns can be avoided in time. The smart wear field has been developed to this day, and the smart watch worn on the wrist has become a good choice for users because of its good portability and accurate positioning function.
Garmin Fenix3 uses multiple positioning
When it comes to positioning, the first reaction of many of us is GPS positioning. GPS positioning is one of the earliest development methods, and the recognition is indeed very high, but this does not mean that smart wearable devices only use this method. In addition to GPS positioning, the comprehensive use of A-GPS, base station positioning, Wifi positioning and other methods makes the positioning of smart watches more accurate.
Positioning diagram
A variety of nouns are definitely looking at you, so I use the form of a table to briefly talk about their principles and advantages and disadvantages. It can be seen from the table that various positioning methods have advantages and disadvantages, and the combined use effect is better. And although there are positioning functions, depending on the user group and purpose, the positioning method is also different.

For example, children's smart watches that protect children's safety are mostly used in urban areas and at home, so GPS positioning and base station positioning are used, which is the positioning method of AGPS. For the friends who often work in the field, multiple GPS positioning methods are used. More practical.
According to different needs, smart watches will be designed into a variety of positioning methods, and we should also choose to suit their needs when choosing, otherwise the effect will be greatly reduced.
An ADSL filter separates the analogue voice-frequency signals from the ADSL (broadband) data signals(Broadband being defined as data transfer greater than 128KBPS.)
If ADSL filter/splitters are not used, the ADSL data signals are heard as "noise" on any equipment connected to the "normal" telephone-line. Apart from being annoying during a telephone conversation, there is the possibility that the additional ADSL signals may cause problems with alarm-units (etc) that may be connected across the line.
This ADSL-interference is illustrated in the diagram below that shows how the unfiltered ADSL data signals appear across the "standard" telephone equipment.
