Nokia Siemens Networks (NSN) is to close its factory in Bruchsal, Germany, with 650 jobs due to go, reports Reuters.

A spokeswoman for the company said the workers at the plant, which is around 125 km south of Frankfurt, were informed about the plan earlier this week. The first workers are due to leave in the next three to six months.

The joint venture between Nokia and Siemens announced a significant restructuring in November 2011 in a bid to cut EUR1 billion in costs by the end of 2013.

Measures included cutting 17,000 jobs, 23 percent of the global workforce, and selling off various business units as the company moves to specialise in mobile broadband.

In the past year, NSN has sold its WiMax unit to NewNet Communication Technologies, its Expedience proprietary fixed wireless broadband business to CN Tetragen, its fixed line broadband access unit to Adtran and microwave transport business to DragonWave. It was in talks to sell its business support systems division in September.
