A jazz musician named Teri Pall invented a version of the cordless phone in 1965 but could not market her invention, as its 2-mile (3.2 km) range caused its radio signals to interfere with aircraft communications. In 1968, she sold her rights to the cordless phone to a manufacturer who modified it for practical use.
Who was the inventor of the first mobile phone? The technology was invented in the 1920's which was in essence a very large walkie-talkie that could transmit 100's of miles. The inventor was Reginald Fessenden. The technoloâ¦gy became handheld in 1946 thanks to engineer's from Bell Labs with ATT being the first carrier.
