Computer Engineering professor Lin Zhong from Rice University explained that if at some point the quality of mobile communications has deteriorated, you should not stand still and raise your cell phone up to your outstretched arm. From this, the signal strength will not change. The fact is that the cellular network is distributed almost evenly around us, and therefore it is worth changing your location somewhat, that is, moving a few meters from the place where the signal is weak or completely absent. This rule will be the same in the city, in the park, and in the country house, unless, of course, mobile communication is generally supported in the area. In cities, communication is deteriorating due to buildings that affect how the signal reaches the device. The specialist is surprised at why people decided that mobile communications would improve if the cellular device was lifted up.
