Times when information was transmitted by signal fires, drums or pigeons have gone. Nowadays, all the information is transmitted both by wire and without them. But the most traditional way of communication is still a call on a mobile phone. And although we are all so used to calling or answering a call, there are myths about mobile communications. Here are 7 of them:
Communication in the aircraft does not work from ground base stations
Exactly. The technology of using cellular communication on board of the aircraft differs from the ground one, as the aircraft receives a signal from the satellite to its own base station. Therefore, to make a call or send an SMS message, you need to install your own compact low-power base station in the cabin. However, it is not done due to the high cost of such a station.
Communication in transport becomes worse due to the traffic
This is a mistake. The fact is that the speed of your movement does not affect the quality of communication. Just on different sections of roads may be different data rates, which depends on the coverage of a particular operator.
Neighborhood with base stations is dangerous
The maximum safe radiation level must be taken into account. The farther from your mobile phone is the base station, the more powerful the level of radiation coming from the phone itself, even in standby mode. So on the contrary, the closer you are to a cellular station, the less power your phone needs, and therefore less radiation.
Communication becomes worse during a thunderstorm
This is only partially true. Because weather conditions are unpredictable and can be reflected in different ways on mobile communications. This can be due to the banal disconnection of the power cable of the station, and the demolition of the tower by strong winds. During the rain, the frequency range may deteriorate. In fact, in this situation, everything depends on the scale of the weather.
Bars show the quality of the signal: the more, the better
It’s not true. The fact is that the “sticks” in the mobile phone displays the signal strength to the nearest base station. The quality of the network these so-called “sticks” do not affect.
If you can not call the right subscriber, it is not due to poor signal quality of the network, it’s because the number of devices serviced by the tower is much larger than usual, simply put, the limit of subscribers in the network is exceeded.
Operator’s phones and towers emit radiation! We are irradiated and we will die!
Radiation and mobile communication are different things. Mobile communication works with radio waves but they are in the area of non-ionizing radiation! They are followed by infrared light (thermal radiation) and visible light. As you can see, mobile communication has nothing to do with radiation.
Mobile phones emit a field that gives you a headache, you can’t sleep, everything hurts, nothing happens, and everyone gets cancer and dies!
The electromagnetic field is a special form of matter through which the interaction between electrically charged particles. Base station radiation is much less powerful than a telephone in hand. The fact is that the base station does not shine a narrow beam directly into the phone, but “smears” all its radiation in the space around it and the signal strength drops rapidly with distance from the station. So this myth is not true.
