Detailed Answer
Repeater: a device that receives and forwards remote control signals to extend communication coverage. Needed when: 1. Very large areas (port yards/large workshops >200 m); 2. Signal blind spots (inside dock sections/behind segments); 3. Multi-obstacle environments (dense shelving). The repeater must be on the same frequency band as the remote and paired. Lider offers repeater solutions; Xingjia too. Repeaters add delay (~20 ms) — use with caution in latency-sensitive applications.
