Detailed Answer
Construction sites have many wireless interference sources (walkie-talkies, cell towers, other equipment); safeguards: 1. FHSS frequency hopping (standard on LIDEER, the core of anti-interference); 2. Clean 470 MHz band; 3. Independent pairing; 4. Optimized receiver antenna placement (away from metal). With multiple tower cranes on one site, FHSS + independent pairing guarantee no mutual interference.
| Interference | Walkie-talkies/base stations |
| Countermeasure | FHSS + 470 MHz |
| Multi-crane | Independent pairing |
Note:On multi-crane sites, verify pairing isolation one by one.
