Editing West Berlin (section)

==Post and telecommunications==
West Berlin had its own postal administration first called {{lang|de|Deutsche Post Berlin}} (1947–1955) and then {{lang|de|[[Deutsche Bundespost Berlin]]}}, separate from West Germany's {{lang|de|[[Deutsche Bundespost]]}}, and issuing its own postage stamps until 1990. However, the separation was merely symbolic; in reality, West Berlin's postal service was completely integrated with West Germany's, using the same [[Postal codes in Germany|postal code]] system.<ref>[https://books.google.com/books?id=aMgiAQAAIAAJ&q=%221000+Berlin%22 ''Guide to World Commodity Markets''], John Parry, Kogan Page, 1982, page 174</ref>

West Berlin was also integrated into the West German telephone network, using the same international dialling code as West Germany, [[+49]], with the [[area codes in Germany|area code]] 0311,<ref>[https://books.google.com/books?id=3EbrAAAAMAAJ&q=vorwahl+westberlin+0311 ''Der Kunsthandel''] {{Webarchive|url=https://web.archive.org/web/20220327030117/https://books.google.co.uk/books?id=3EbrAAAAMAAJ&q=vorwahl+westberlin+0311&dq=vorwahl+westberlin+0311&hl=en&newbks=1&newbks_redir=0&sa=X&ved=2ahUKEwjL6fqk9sfzAhUyQkEAHVYQDH4Q6AF6BAgCEAI |date=27 March 2022 }}, Volume 63, A.

In order to reduce eastern wiretapping of telecommunications between West Berlin and West Germany, microwave radio relay connections were built, which transmitted telephone calls between antenna towers in West Germany and West Berlin by radio. Two such towers were built, one antenna in Berlin-[[Wannsee]] and later a second in Berlin-[[Frohnau]], finished on 16 May 1980 with a height of {{cvt|358|m|0}}. This tower was demolished on 8 February 2009.<ref>{{Cite web |url=https://structurae.net/structures/richtfunkmast-berlin-frohnau |title=Richtfunkmast Berlin-Frohnau (Berlin-Frohnau, 1979) |access-date=7 October 2016 |archive-date=9 October 2016 |archive-url=https://web.archive.org/web/20161009144801/https://structurae.net/structures/richtfunkmast-berlin-frohnau |url-status=live }}</ref>
