C-Netz

The Radio Telephone Network C (German: Funktelefonnetz-C, abbreviated as C-Netz), was a first generation analog cellular phone system deployed and operated in Germany (at first West Germany) by DeTeMobil (formerly of Deutsche Bundespost Telekom, currently Deutsche Telekom). It utilized the C-450 standard, originally developed by Siemens AG, and was the third and last update of a series of analog mobile phone systems used primarily within Germany, superseding the B-Netz and the A-Netz before it. It has been decommissioned, replaced by both the newer D-Netz and E-Netz systems, both based on GSM standards (which are digital) and operating on 900 MHz and 1800 MHz bands respectively.

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. This differs from previous systems used in Austria (A-Netz, B-Netz) that were based on German standards.
