Interesting facts about mobile communications. Did you know about this? ..
Mobile communication has firmly entered our lives and has become absolutely familiar. But there are many facts that most of us do not even realize. Here are some of them. Kostenko Maxim, Shutterstock.com Cellular or Mobile? Is soup and food the same? On the one hand – yes, on the other – not really. Anyone understands that soup is a type of food. A mobile phone is a device with the help of which we can stay in touch, moving within a certain territory, as opposed to a stationary one. Therefore, a mobile phone, a satellite telephone, and a cellular phone familiar to everyone, which can be used within the coverage area of a cellular network, can be attributed to mobile phones. In this case, the communication between the subscribers’ phones is maintained by means of base stations, which, like cells, are scattered throughout the country or region.

This means that a cell phone is simply a type of mobile phone. But practically the number of satellite and radio telephones in the world is incomparably smaller than the number of cellular ones. And we often use these names as synonyms. 100% coverage is real! Most cell phone owners faced a situation when, being in a sparsely populated area, they found themselves outside the network coverage area. Unfortunately, operators cannot afford to deploy base stations in such areas due to their financial unprofitability. In such cases, satellite communication comes to the rescue. The principle of its operation is similar to the functioning of cellular communication. Only the role of base stations is performed by artificial satellites of the Earth.
Some satellite operators have such an extensive satellite network that they cover the entire Earth with their services, including the North and South Poles. But, unfortunately, such pleasure is expensive. The simplest satellite phone with a minimum set of functions costs no less than the modern flagship cell phones of famous brands. This is not to mention the cost of service … your smartphone is more voracious than a refrigerator! After reviewing the technical documentation for both devices, you will say that the power consumption of the refrigerator is ten times higher. But the refrigerator is limited only by the consumption of electricity from the home network. And when using a cell phone, energy is needed not only to recharge the device, but also to service base stations, servers, Internet communications, etc. Therefore, on average, for one smartphone, as calculated in the investment consulting group Digital Power Group, 360 kWh per year, and about 320 kWh per year per fridge. Like this! More megapixels – better photos? Surely, many were faced with a situation where the quality of a photo on a phone with a camera, for example, in 3 megapixel turned out to be higher than with a camera in 5 megapixel. The thing is that this characteristic (resolution) simply shows the number of pixels of the image. The higher the resolution, the larger the photo can be printed. But the image quality is also influenced by the size of the matrix on which the image is projected. The larger it is, the clearer the picture is. Therefore, paradoxically, but of the two phones that have the same matrix size, it would be better to take one that has lower resolution (less than Mp). Unfortunately, the vast majority of manufacturers in the technical documentation do not indicate the size of the matrix of the camera phone. Why then is everyone chasing megapixels? The fact is that most often with the increase in resolution, manufacturers use larger matrixes. But this is not always the case …
