Staff working in the GSM and WiMAX technology divisions in several countries, including the United States and the UK, are being given their pink slips and P45s.
Nokia Siemens wants to improve its competitiveness "as a standalone entity" and ended talks about a possible stake sale to private-equity investors.
Nokia Siemens paid $975 million for the Motorola assets, which include wireless technologies based on the CDMA standard used by Verizon Wireless and Sprint Nextel as well as some Asian carriers.
According to Reuters, the company will also transfer as many as 1,200 former Motorola employees internally as it reorganises the acquired GSM and WiMAX networks businesses.
There's that WiMAX doing well again, then.
Nokia Siemens had about 73,000 employees worldwide at the end of the second quarter.
