The first wireless conversation ever occurred in 1880 when Charles Sumner Tainter and Alexander Graham Bell invented the photophone. However, though great efforts have been made to improve cellular networks in terms of support for new and innovative services, greater number of subscribers, higher speed, and larger bandwidth, very little has been done to update the security of cellular networks. endobj All Rights Reserved.
