The short distance is the on-the-spot channel environmental simulation device of micropower radio communication for the power communication

The utility model discloses a short distance is the on-the-spot channel environmental simulation device of micropower radio communication for the power communication, in the device, the attenuator is connected with attenuator input interface, attenuator output interface and communication interface respectively, the attenuator input interface is used for treating deamplification to the attenuator input, the attenuator be used for to attenuator input interface type treat export the attenuator output interface after deamplification is processd to, the attenuator output interface is used for the output attenuation signal, communication interface is used for receiving the external control signal and offers the attenuator, said application of installation is in the communications network that host node and at least one slave node constitute, and host node and slave node are detected micropower wireless telecom equipment, and the host node is through the one first slave node is connected to said device, through the two a second slave node is connected to the device to this analogizes, is connected to final slave node. The utility model discloses can to the short distance for the power communication the on-the-spot channel environment of micropower radio communication simulate.
