CRFS Built a Map for the Invisible Battlefield
Its rugged blue-and-white boxes do not transmit. They listen - then turn crowded radio noise into locations, alerts and evidence for militaries, regulators and intelligence teams.

Mauna Kea Semiconductors Corporation
Mauna Kea Semiconductors (MKSemi) is a Silicon Valley fabless chip company building what it calls the world's lowest-power ultra-wideband (UWB) technology - the short-range radio that lets phones, wearables, cars and IoT devices know precisely where they are and which direction they're pointing, down to a few centimeters. Founded in 2019 by semiconductor veterans and headquartered in Cupertino/San Jose with engineering hubs across China, MKSemi sells UWB chips, modules and SDKs, headlined by its highly integrated MK8000 SoC, to device OEMs and ODMs chasing precise location, secure ranging and radar-style sensing on coin-cell batteries.
