Network routing device, network data transmission method, and network access device

A method, comprising:

• converting a received data signal into at least two baseband signals;
• converting one of the at least two baseband signals into a radio frequency signal by using a first radio frequency unit, and then sending the radio frequency signal by using a first antenna;
• and
• converting another baseband signal of the at least two baseband signals into a network signal that is transmittable in a wired transmission medium, and then sending the network signal to the wired transmission medium for transmission.

A device comprising a second network transmission processing module, at least one second radio frequency unit, a second antenna corresponding to the second radio frequency unit in quantity, and at least one second wired communication module, wherein

• the second network transmission processing module has at least two second baseband signal data interfaces, one second baseband signal data interface is connected to one end of the second radio frequency unit, the other end of the second radio frequency unit is connected to the second antenna, and the other second baseband signal data interface is connected to the second wired communication module;
• the second radio frequency unit is configured to:
• convert a radio frequency signal that is received by using the second antenna into a baseband signal, and then send the baseband signal to the second network transmission processing module through the second baseband signal data interface;
• the second wired communication module is configured to:
• be connected to a wired transmission medium, convert a network signal that is received from the wired transmission medium into a baseband signal, and then send the baseband signal to the second network transmission processing module through the second baseband signal data interface;
• and
• the second network transmission processing module is configured to:
• receive, through the second baseband signal data interface, the baseband signal sent by the second radio frequency unit, receive, through the second baseband signal data interface, the baseband signal sent by the second wired communication module, parse the received baseband signals, and then obtain data carried in the baseband signals.
