Cell Phone

A mobile radio telephone, often in an automobile, that uses a network of short range transmitters located in overlapping cells throughout a region, with a central station making connectionto regular telephone lines. Also called cellular telephone. The cell phone system was introduced in 6-17-1946. Today's communication industry would not be what it is without the contributions made by Richard H. Frenkiel and Joel S. Engel. The big break through came when AT &T lab researchers Frienkiel and Engel divided wireless commnications into a series of cells, then automatyically switched colors as they moved sotyhat each cell could be reused. On june 17 1946 a driver in St. louis, Missouri, pulled out a handset from under his car's dashboard, placed a phonecall and made history. It was the first mobile telephone call.Mobile phones are used for variety of purposes, including keeping in touch with family members, conducting business, and having access to a telephone in  the event of an emergency.
