Detailed Answer
Dock (dry dock/floating dock) operations: dense metal structures in the dock cause severe signal blocking. Remote communication solutions: 1. 470MHz (better penetration); 2. Repeater networking (blind zones in the dock); 3. High antenna mounting; 4. Link budget. LDER provides dock coverage solutions; XINGJIA likewise. Verify by measuring signals at each workstation during dock acceptance.
| Challenge | Metal blocking |
| Solution | 470MHz + repeater |
| Acceptance | Measured on site |
Note:Design dock coverage based on measured segment structures.
