Origins (1847–1978) , was produced by Siemens-Reiniger. Siemens Communications traces its origins to the company
Siemens & Halske Telegraph Construction Company (German legal name: Telegraphen-Bauanstalt von Siemens & Halske) founded by
Werner von Siemens on 12 October 1847. Based on the
telegraph, his invention used a needle to point to the sequence of letters, instead of using
Morse code. In 1848, the company built the first long-distance
telegraph line in Europe – 500 km from Berlin to
Frankfurt am Main – and by the early 1850s the company was involved in building long distance telegraph networks in Russia. In 1867, Siemens completed the monumental Indo-European telegraph line stretching over 11,000 km from London to
Calcutta. In April 2014, the NSN name was phased out as part of a rebranding process. Siemens Enterprise Communications GmbH & Co. KG was split from the enterprise division. Two years later, in October 2008 it merged into a new entity
Siemens Enterprise Communications – a joint venture between Siemens AG (49%) and
the Gores Group (51%) to collaborate across wireless, fixed and enterprise networks. The venture was named Open Communications, and the IP phones it produces are called OpenStage. The Wireless Modules business unit of Siemens Communications (which designs and manufactures GSM and 3G modules for the M2M markets) moved to Siemens' Automation & Drives division, and became a stand-alone entity known as
Cinterion Wireless Modules, later acquired by Gemalto.
