B-Netz was an analog, commercial mobile radio telephone network that was operated by the Deutsche Bundespost in Germany (at first only West Germany) from 1972 until 1994. The system was also implemented in neighboring countries Austria, The Netherlands and Luxembourg. The B refers to the fact that it was the country's second public mobile telephone network, following the A-Netz. The B-Netz would eventually be superseded by the technically superior C-Netz, which was put into operation on May 1, 1985.
