All objects in nature always transfer heat in the form of electromagnetic waves and particles as long as the temperature is above absolute zero. This way of transmitting energy is called radiation.
Objects (gases) radiate outward regardless of temperature. Object A can radiate to object B, and object B can also radiate to object A. This term is usually used for ionizing radiation.
Wireless landline, also known as TD business treasure, is a telephone terminal tailored for small and medium-sized enterprises and individuals. TD business Abao terminal can not only make phone calls normally, but also send and receive short messages and read aloud by voice. No wiring, easy to carry.
Question 2: Will the wireless fixed telephone really have strong radiation? In fact, this issue was not put forward recently, and it triggered a lot of discussions in this area shortly after the launch of wireless products; Now is a world full of radiation, which is absolutely true. The radiation source is getting closer and closer to our daily life-in the past, it was only the high-voltage power equipment in the factory, then the substation equipment in the community, then the TV set, monitor at home, and then the portable mobile phone are also included in the radiation source, so it is expected to discuss the radiation problem of wireless network products.
But before introducing the radiation of wireless network products, I want to talk about the radiation of mobile phones first. Nowadays, many people use mobile phones every day, and there are almost no reports that they are worried about the radiation of mobile phones. We urge everyone to use them as little as possible. However, you may forget that a few years ago, there was another news that caused a strong debate in China-a short message about a medical institution, saying that the radiation of mobile phones could easily lead to brain cancer. In fact, the radiation of mobile phones is far less than that of microwave ovens, but why are people so worried when using microwave ovens, but so worried when using mobile phones? It's very simple, because the mobile phone is next to your head and the microwave oven is in the kitchen, so when talking about radiation, we should also consider the use of the product: wireless networking products are generally placed on the ground when working, and will not be close to the human body, so if it does not have strong signal transmission power, it will not cause harm to the human body.
Speaking of this, some friends will ask: So how big is the power of wireless network products?
According to the tests of various research institutions, at a distance of two feet, an 802. 1 1b transmitter can generate about 2 microwatts per square centimeter (that is, one millionth of a watt per square centimeter) with the roughest calculation method and the highest transmission frequency. What is the concept of this data? Let's compare it with some reference objects: in our daily life, the radiation generated by TV and broadcasting equipment is about per square centimeter 1 microwatt (so the radiation of 802. 1 1b equipment is only twice this data). Of course, we won't feel any discomfort in such an environment, but what about the radiation emitted by mobile phones? According to the test, the transmission power of CDMA mobile phones currently used in the market is about1.55w to1.07W, while the transmission power of GSM mobile phones is1.49W at the highest and 0.22W at the lowest, which is n times larger than that of wireless network equipment. However, we still use mobile phones every day, so why should we worry about the radiation problem of wireless network equipment?
In fact, the FCC of the Federal Communications Commission of the United States has stipulated that as long as the radiation of wireless network equipment is limited to 0/000 microwatts per square centimeter/kloc, it is safe. Therefore, even if multiple wireless devices are used in a room at the same time, it will not cause direct harm to the human body (of course, there may be some indirect effects, but there is no clear research report from any research institution to confirm the existence of this problem).
In addition, the popular 802. 1 1g actually has a lower radiation index than 802. 1 1b, so there is no need to worry too much about using wireless products. If you really feel uneasy, you may wish to refer to the guidance of some experts:
One: Try to stay away from electromagnetic radiation in daily life. If you really can't leave, try to shorten the time of close contact.
Second, the installation of stainless steel screen window has good shielding effect and can reduce radiation by dozens of times.
Eat foods rich in vitamin A, vitamin C and protein, such as carrots, kelp, cabbage and animal liver, to strengthen the body's ability to resist electromagnetic radiation.

In addition, my advice to you is to put an end to the use of mobile phones, which are placed far away from home.
Question 3: To what extent does the wireless fixed telephone radiate? 1. "Wireless fixed telephone" is an ordinary mobile phone. In order to approach the communication effect of the fixed telephone as close as possible, its transmission power has reached the maximum limit of the national standard, and its radiation value even exceeds the national standard. During the call, the radiation is greater, and the radiation amount is about 3 times that of standby.
Question 4: Is there radiation on China mobile wireless landline? Wireless fixed telephone is to make a mobile phone look like a fixed telephone, plug it in and put it at home as a wired fixed telephone. Because this wireless fixed telephone does not need to be wired through a hole in the wall, it can be used anywhere by plugging in the power supply. Generally, the phone will be sent as soon as it is stored, and the phone bill is also cheap. So recently, many families have removed the wired fixed telephone at home and replaced it with this convenient and fashionable wireless fixed telephone. As everyone knows, this change replaced a clean and radiation-free fixed telephone, but invited a healthy invisible killer at home. The Ministry of Industry and Information Technology stipulates that this kind of wireless fixed telephone, as a supplement to wired fixed telephone, can be developed in a limited way where telephone lines are not covered or not completely covered, but only TD-SCDMA system (i.e. low-radiation CDMA system) can be used. At present, China Mobile's TD-SCDMA national network has not been built, so almost all the wireless fixed telephones developed before are GSM, with low frequency and large radiation. Because it is a relatively fixed mobile phone and uses alternating current, it is not necessary to consider the battery standby problem, but also to consider the call effect as close as possible to the fixed phone, so its transmission power is often the maximum of the national standard limit, even exceeding the national standard radiation value. Buying such a wireless fixed telephone at home is to introduce an invisible radiation killer. Its transmission power is equivalent to 5 PHS outdoor base stations. Super radio waves are released in your home 24 hours a day. The proliferation of wireless fixed telephones is caused by the disorderly competition between mobile operators and fixed operators in the communication industry.
Question 5: Will the wireless landline radiate when not in use? The radiation you are talking about should be electromagnetic waves. At present, the electromagnetic wave products on the market are harmless, so don't worry. Don't believe that electromagnetic radiation harms people, only particle radiation harms people, because that is nuclear radiation.
Question 6: Does the mobile wireless landline have radiation? There is radiation, but there is only a weak point.
Generally speaking, the radiation of wireless landline is not as big as that of mobile phone. Any communication electronic product will have a little radiation more or less.
Question 7: Does the fixed telephone of the wireless landline at home (telecom) radiate? Hello:
The wireless landline at home has radiation, which is too small to cause harm to human body. Please feel free to use.
I hope my answer is helpful to you. If in doubt, please continue to consult us.
Question 8: Is the radiation of telecommunication wireless landline large? The wireless landline of telecom uses CDMA network, and this radiation is even smaller than the mobile phone you use, which is basically negligible.
Question 9: Does the wireless landline with card have radiation? Wireless fixed telephone is to make a mobile phone look like a fixed telephone, plug it in and put it at home as a wired fixed telephone.
