Helsinki - Nokia, the world's largest maker of mobile phones, Wednesday said it planned to concentrate its mobile research and development to fewer sites in Finland and introduce temporary layoffs to counter lower demand.
The site for mobile research and development in the city of Jyvaskyla, was to be closed by the end of 2009, impacting some 320 employees, the group said.
Research and development sites were to remain in Tampere, Oulu, Salo and the greater Helsinki area.
