Tips

usage

低频 has a strict technical sense (low-frequency electromagnetic / sound waves, typically 30-300 kHz in radio terminology) and a colloquial business sense — 低频消费 ('low-frequency consumption,' i.e. things people buy rarely, like houses or cars), contrasted with 高频消费 (groceries, coffee). The opposite is 高频 (gāopín, high-frequency).
