About the Company

Nokia

Makes network gear for carriers and data centers

Nokia makes the equipment and software that mobile carriers, cloud companies, and businesses use to run networks, from cell-tower radios to fiber links between AI data centers. From 1998 to 2011 it was the world's largest mobile phone maker; it sold that business to Microsoft in 2014, and HMD Global, a separate company, makes Nokia-branded phones under license. Its network unit sells optical systems that send data over fiber, internet routers, and broadband gear, and its mobile unit sells radios and the core software that runs 5G networks. Nokia earns money from equipment and service contracts and from licensing its patents to phone makers and carmakers. It was founded in 1865 as a wood pulp mill and is based in Espoo, Finland.
