Marvell enters the 6G cycle from a position of strength that is quietly eroding. The company supplies the custom baseband silicon at the heart of the non-Chinese RAN — OCTEON Fusion processors and OCTEON DPUs sit inside Nokia’s ReefShark chipsets and Samsung’s massive-MIMO base stations. That franchise defined Marvell’s role in 5G. It does not obviously survive into 6G intact, and the company’s maneuvering over the past year reads as an attempt to convert a declining incumbency into something more durable.
