The invention relates to a dual-mode analog networking unit and a multi-level dual-mode analog networking system. The dual-mode analog networking unit includes a user electric meter, a dual-mode comprehensive wave trapper, a signal access antenna, a signal output antenna, a carrier attenuator, a wireless attenuator and a combiner. The user electric meter has a carrier wireless dual-mode communication module. The dual-mode comprehensive wave trapper has a power input end, a coaxial input end, a power output end and a coaxial output end. The power output end is connected with the user electric meter and the coaxial output end is connected with the carrier attenuator. The signal access antenna is connected to the coaxial input end. The signal output antenna is connected to the wireless attenuator. The combiner is connected to the carrier attenuator and the wireless attenuator. The dual-mode analog networking unit realizes an independent carrier channel and a wireless channel between nodes in a network, and solves a problem that a carrier signal and a radiofrequency signal in the dual-mode communication analog network are difficult to separate. Further, the structure of analog networking system is simplified and cost is reduced.
