the indoor covering device includes: the signal source is used for generating two paths of first communication signals; one of the two paths of first communication signals is sent to a combiner, and the other of the two paths of first communication signals is sent to a second antenna unit; the combiner is used for receiving the one-path communication signal; combining the one-path communication signal with a second communication signal to obtain a first combined signal; sending the first combined signal to a signal receiving unit; the second antenna unit is configured to radiate the other path of communication signal to the terminal; the communication system of the first communication signal is different from that of the second communication signal;
the signal receiving unit is used for receiving the first combined signal; sending the first combined signal to a first antenna unit;
and the first antenna unit radiates the first combined signal to a terminal.
7. The passive indoor subsystem of claim 6, wherein the indoor covering means further comprises:
the power amplifier is used for amplifying one path of communication signal in the two paths of first communication signals;
the amplified one-path communication signal is used for the combiner and a second communication signal to be combined to obtain a second combined signal and sending the second combined signal to the signal receiving unit, so that the signal receiving unit radiates the second combined signal to a terminal through the plurality of first antenna units.
8. The passive room subsystem of claim 6,
the information source is specifically configured to: under the condition that the number of the passive indoor distribution systems is N, generating 2N paths of first communication signals; n is a positive integer greater than 1; and sending N paths of communication signals in the 2N paths of first communication signals to a combiner, and respectively sending the other N paths of communication signals in the 2N paths of first communication signals to N second antenna units.
9. The passive room subsystem of claim 6,
when the information source is arranged in a first scene, the second antenna unit is a directional antenna.
10. The passive room subsystem of claim 9,
when the information source is arranged in a second scene, the second antenna unit is an omnidirectional antenna;
wherein the second scene is different from the first scene.
