(一) Communication distance

Scenario:
Due to the distance between the airport and the airport, it is impossible to use radio equipment for instant communication.

Solution:
The radio gateway is set up in each airport. Through the network, the airport and the airport can communicate in real time through the existing radio equipment.

(二) Communication blind spot

Scenario:
The port container yard would be easily shielded by radio signals due to stacked containers.

Solution:
Use traditional radio and PoC IP radio, and solve the problem of radio being shielded through 4G network.
