24 GHz legacy bands phased out; 77/79 GHz codified as global standard
Automotive Radar Market 2025 to 2032: ADAS Mandates, Electrification and the Shift from Optional to Essential →Regulators are transitioning remaining legacy 24 GHz systems exclusively to aftermarket replacement, codifying 77 GHz and 79 GHz mmWave bands as the global high-resolution sensing standard. Buyers should also note structural migration toward radar-on-chip (RoC) and 4D imaging radar, the latter projected at a 79.2% CAGR from USD $0.42 billion in 2026 to USD $4.33 billion by 2030.
Severity: how big the impact would be if this plays out.
Likelihood: how probable the engine judges it is to happen or persist.
Spend exposed: the share of your annual category spend this flags.
Audit current programs for any 24 GHz radar dependencies and plan migration to 77/79 GHz platforms
Legacy-band sourcing windows are closing as regulators restrict 24 GHz to aftermarket use only.
