1 ene 1965 año - First Cordless (Wireless) Phone
Descripción:
The first cordless phone model was developed by a Jazz musician named Teri Pall. In 1965 she invented a version of the cordless phone with a range of two miles. It operated using low radio frequencies. Unfortunately she could not sell her invention because the radio signals interfered with aircraft. She sold her idea and rights for the cordless phone to a manufacturer who could modify it for practical use.Añadido al timeline:
