The Inventor of Cordless Phones

The name Teri Pall may not be familiar to many ears, but her invention is used by ears worldwide.  Pall, a jazz musician, innovated cordless phone communication in 1965, a technology that works when a base station sends out radio signals to a handset.  The signal sent by the phone was very low frequency, originally 1.7 MHz, and worked within a limited range.

Security for low frequency phones was a concern for users.  In the modern era, cordless phones function on higher frequency, which expands the area in which the phone user can move.  In addition, the higher frequency provides both quality sound and greater security.  In 1994, the Federal Communications Commission (FCC) allowed companies to manufacture phones at 900 MHz, and later 2.4 and 5.8 GHz.

Cordless phones are a small miracle of convenience for consumers.  Whereas older phones were bulky and user mobility was restricted, cordless phones allowed for free movement.  It’s an innovation that changed the way we look at phone communication.
