The principle behind cell phones, transmitting waves modulated with sound signals (see methodology) was first seen in radio communications developed in the 1920s. However the potential of this [[Cellular technology|technology]] was not realised for many years, and the move towards the networks used today did not begin until 1947, when Bell Laboratory engineers Douglas Ring and Rae Young proposed using hexagonal grids with base towers at the corners (rather than in the centers) to allow communication. This creation of the "cellular concept" resulted in increased research into the possibility of evolving commonly used 2-way radio communication into real time speech.
