The Radio Telephone Network C (German: Funktelefonnetz-C, abbreviated as C-Netz), was a
C-Netz was active from 1985 to 2000, with certain areas until 2001. Since then, all consumer cellular phone services in Germany are digital-only.
The dialing code for the C-Netz was 0161, which is no longer in use. As a result, users were not able to transfer their numbers to GSM networks when the C-Netz was shut down. Austria used an unrelated system with the same C-Netz name which instead utilized the NMT standard.[1] This differs from previous systems used in Austria (A-Netz, B-Netz) that were based on German standards.
Timeline
The C-Netz was officially introduced in 1985 (with unofficial trials in 1984) to replace the existing B-Netz/B2-Netz system used in Germany at the time. Due to problems with the B-Netz mobile networks, early adoption of C-Netz was very high, especially in rural areas which had lacked prior B-Netz coverage. However, like other first-generation analog systems, it suffered from poor call quality and was susceptible to eavesdropping. The system was built up in West Germany and West Berlin, but following German reunification in 1990, was rapidly built up in the new German states.
By December 1988, the service had grown to nearly 100,000 customers, and reached a peak user base of around 800,000 in the early 1990s. It remained popular throughout the decade as a preferred system for mobile car phones, particularly rural
