Will raising the phone in the sky help increase the signal of a cellular signal?

We often encounter weak phone waves. The reason may be due to many factors such as when the terrain is difficult to catch, where people are too crowded like concerts . And in such situations, the first thing people often do is raise the phone to the sky , hope to get the wave.

But is this action really useful?

In the talk on this topic, Lin Zhong, a professor of electrical and computer science at Rice University, said 'no'. He said, around us, phone waves are almost identical. Raising your hands high will not help change the signal quality, but going around may help, especially in cities.

Mobile waves in cities are also affected by high-rise buildings, so moving even a little can change the quality of cellular signals.

The conclusion is, do not hold up the phone anymore, that does not help to add any wave lines.
