It can be understood that the networking device for NSA provided by the embodiment of the present invention belongs to a part of a wireless communication system, and belongs to the fact that a 4G baseband processing device and a 5G baseband processing device share a radio frequency unit to implement transceiving of antenna data. This networking device includes: a first baseband unit 10, a second baseband unit 20, and a mixed-mode rf module 30, wherein,

the second baseband unit 20 is configured to process at least 5G baseband data, and the first baseband unit 10 is configured to process other baseband data different from the 5G baseband data;

the second baseband unit 20, as a 5G baseband processing device, may process at least 5G baseband data, and the first baseband unit 10, as another baseband processing device, may process 2G/3G/4G baseband data, where the units may be one baseband processing device or a plurality of baseband processing devices.

A first communication link is constructed among the first baseband unit, the second baseband unit and the mixed-mode radio frequency module;

the first baseband unit 10 is configured with a first communication link to the mixed-mode rf module 30 via the second baseband unit, in order to implement information transmission different from 5G baseband processing devices, such as 4G baseband processing devices and rf devices, and the information that can be transmitted includes signaling, baseband data different from 5G and corresponding antenna data. Implementation of the first communication link may enable transmission of other baseband data on the 5G baseband processing device. A second communication link is constructed between the second baseband unit and the mixed-mode radio frequency module;
