Radio frequency network topology simulating apparatus

The invention discloses a radio-frequency network topology simulation device, which is used for simulating and verifying network characteristics between at least one transmitting terminal and at least one receiving terminal. The device comprises a noise generating device and at least one first radio-frequency processing device connected with the output end of the noise generating device; and the first radio-frequency processing device comprises a first integrated unit which is used for receiving and outputting radio-frequency signals of the transmitting terminal and noise signals of the noisegenerating device after the integrated processing. Through controlling the mode that a noise signal level is larger than a space radiation level of the transmitting terminal, space radiation signals of the transmitting terminal are drown out by the outputted noise signals, so the topology connection state between the transmitting terminal and the receiving terminal can be controlled, an almost real radio-frequency simulating environment is provided for the transmitting terminal and the receiving terminal on the connection of a radio-frequency channel, the network characteristic between the transmitting terminal and the receiving terminal can be further simulated and verified in a short distance (such as indoor), thereby saving manpower and material resource.
