Problems solved by technology

In the traditional way, ISCS cannot confirm whether COCC has received the ferry data, nor can it measure the transmission time of all ISCS data, nor can it adjust the data transmission method according to the data application requirements of COCC
The traditional transmission method is suitable for applications with small data volume and low data quality requirements; for massive ISCS real-time data transmission with strict data quality requirements, the traditional method cannot guarantee the data quality, the transmission time cannot be measured, and the COCC side cannot respond to the demand fatal flaw
