Second post

In 1926 Bell Labs and the British Post Office engineered the first two-way conversation across the Atlantic. The first commercial transatlantic telephone call was between New York City and London and occurred on January 7, 1927.

While the term "wireless" in this context means radio and can refer to any telephone that uses radio waves (such telephones have existed since 1915: see "Hello, Hawaii, How Are You?"), it is primarily used for cellular mobile phones. In the United States wireless companies tend to use the term wireless to refer to a wide range of services while the cell phone itself is called a mobile phone, mobile, PCS phone, cell phone or simply cell with the trend now moving towards mobile.
