Problems solved by technology

The main problem of MoCA is: its design bandwidth is 50MHz, which cannot meet the requirements of the TV channel bandwidth of my country's TV system at 8MHz
In addition, MoCA requires that the adjacent frequency band of 50MHz cannot be used, which leads to low system efficiency
Moreover, it is designed for the home network, not fully suitable for the application requirements of broadband access
