Challenge

Selectively poor communication or network cellular signal for some carriers on board. But the crew and passengers need the full signal of all carriers on the sea.

Solution

  1. Selected a best possible 5.5-7dBi high gain omnidirectional donor antenna with pole or wall mounted;
  2. Made the correct 1/2 coaxial cable connectors;
  3. Well controlled the length between donor antenna and the booster within 20-60 meters, and the curvature cannot be greater than 60°;
  4. Placed the signal booster in the right position, better heat dissipation and power connection. We chose the full carriers, full band booster with every two ports for outdoor and indoor antennas;
  5. Ensured the diameter distance between indoor ceiling antenna and outdoor omnidirectional donor antenna bigger than 12 meters, preventing from self-circulating amplification;
  6. A three-joint splitter was applied for this case. One point was connected to the booster, while the other was split into three joint linking to different indoor antennas on each floor.

Result and Effect

Before: RSRP -96, RSRQ -9, SINR 9.0

After: RSRP -59, RSRQ -8, SINR 9.0
