today's smart wear market, in addition to the adult users of the conventional smart watches and smart bracelet, child intelligence The wearable market has also become the object of attention. The new term began, many parents in addition to the children to purchase a variety of learning supplies, in addition to the traditional school bags, stationery and guidance books, this year, the opening of the school has a new upsurge:
a telephone watch for children. Children's telephone watches are welcomed by their parents with their strong positioning, telephone and micro chat functions, and many brands of telephone watch sales are breaking through the million mark.
children's smart wear products represented by children's watch watches, compared with conventional smart watches or smart bracelets, are more like a new kind of need because it solves the problem of child safety that worries parents, and improves Parent child communication, so children's call watch has become an essential part of today's children. However, there are many kinds of children's call watches on the market, which make many parents feel helpless.
recently, relevant negative news reports about children's smart positioning watches have aroused everyone's concern. There is a certain amount of radiation in children's telephone watches, which may affect children's development. Some parents who are unaware of the truth are panic. Is there any hidden danger to children's health and safety by electromagnetic radiation from children's telephone watches? Is there a scientific basis for this statement? The little ray will give you a discussion today.
as long as people live in places with signals, light, and electricity, there will be electromagnetic radiation. For example, the electric lights, phone, phone, mobile phone, computer, TV, microwave oven, hair dryer and so on every day will produce electromagnetic radiation, even the ubiquitous mobile communication signal tower around you will produce electromagnetic radiation, just invisible to the naked eye. According to the introduction, the WHO (WHO), since 1996, has organized more than 60 countries and several international organizations to carry out the global "international electromagnetic program". It took 10 years to carry out comprehensive health risk assessment of electromagnetic radiation in life, including childhood cancer, adult cancer, depression, suicide, cardiovascular disorders, Infertility, dysplasia, immune system variation, neurobiological effects and neurodegenerative diseases. Finally, the WHO expert group concluded that there is no actual health problem in the electromagnetic radiation commonly encountered by the public. That is to say, the radiation absorptivity is within the national safety standard, and there will be no problem.
and the majority of children's call watches sold on the market are using GSM communication technology, working in the 900MHz and 1800MHz bands, which belong to the category of non ionizing radiation. This kind of radiation, within a certain range of energy intensity, only produces tiny thermal effects on the human body, which does not exist in danger of destroying the stable structure of the chemical bonds of the organism. Broadly speaking, in the same environment, the electromagnetic field intensity of children's call watch and ordinary mobile phone is the same.
children's telephone and watch radiation mainly comes from the antenna, including the external antenna and the built-in antenna. The radiation of the telephone watches produced by the regular manufacturers is generally in accordance with the national standard. According to the report of the authority's testing report, the radiation of regular children's telephone watches is far less than the national standard of 2 watts / kg. That is to say, as long as the radiation value is less than or equal to the national standard value, it is safe to comply with the national standard. As we all know, cell phones are directly attached to the ears and are closer to the brain, while children's telephone watches are 10-15 centimeters away from the head. The radiation of children's telephone watches is smaller than that of mobile phones. Of course, it is not ruled out that some of the dirty phone watches will exceed the standard radiation, and parents are advised to buy regular factory products through regular channels.
at present, many domestic brands have produced Smart Phone Watches with telephone functions. A wearable device with children to carry and communicate at any time is also essential for parents and children themselves. It seems that such a new need still exists. On the basis of the child's normal learning, the child's call watch can be considered for the child on the basis of no additional game and entertainment function.
