Intel’s long lasting schizophrenic relationship with cellular chips has ended with its decision to cease manufacturing 4G and 5G modems in the wireless wire area network (WWAN) business (see separate short story this week). Such chips went into notebooks, for which Intel will continue to make CPUs and rely on Taiwan’s MediaTek for modems in future. The move appears to mark Intel’s judgment that anticipated volumes of 5G chips for notebooks are too low to justify continued investment, as wireless connectivity itself becomes commoditized and the added value resides in chips or accelerators for the applications. But while it may reflect Intel’s ultimate failure to establish a stronghold in the wireless semiconductor market it also highlights the changing dynamics of…
