3 big deals happened at Nokia. They sold the devices business to MS. They acquired the Siemens half of Nokia Siemens Networks. They acquired Alcatel Lucent (French Alcatel and American descendant of Bell Lucent) and merged it with what was NSN. They sell every component of the modern networking stack from 5g antennas to undersea cables.
Outside China, though, Ericsson now claims to serve more operators than just about any other vendor. Ekholm today put Ericsson's share of the market for radio access network (RAN) products at 39%, excluding China, telling analysts it has grown from just 33% when he took over in 2017. Fifty percent of 5G traffic outside China runs over Ericsson, he said, while 16 of the world's top 20 operators are using its 5G core.
