Nokia is a Finnish telecommunications equipment company founded in 1865 as a paper mill, which became the world's largest mobile phone maker in the 1990s before selling that business to Microsoft in 2014. It now supplies network infrastructure to operators and enterprises, covering radio access equipment for mobile networks, optical and IP routing for transport networks, fixed broadband access, and a technologies division that licenses its cellular patent portfolio. Headquartered in Espoo and listed in Helsinki and New York, it runs Nokia Bell Labs as its research arm and has been expanding into data centre networking as operator spending has slowed.
