In Monthly Notices of the Royal Astronomical Society publish It has been told in the study that by using the signals of the mobile tower, aliens may be able to find us. Significantly, in the last decade, a network of mobile phone networks has been laid on the earth. For this, every country has installed millions of radio transmission towers, which are also commonly known as mobile towers.
Because of the presence of millions of mobile towers on our earth, some part of the radio signals emanating from them also goes into space. The study says that if aliens also have technology and are equipped with capabilities related to radio astronomy, then signals emanating from Earth can be detected in a dozen light years or less.
According to a report, the maximum leakage of radio signals is from military radar. After that comes the number of mobile phone towers, because their number is increasing. However, aliens will be able to reach us only when they are technically resourceful. The study does not say how likely the aliens are to have hi-tech technology. Research says that if there are aliens in the star system closest to Earth, they can detect radio signals from cell phone towers.
