Abstract
Provided are an indoor distribution system and a signal transmission method. The system includes an access unit, an extended unit, a first coupling unit, and at least one remote cascaded chain. Each remote cascaded chain includes at least one second coupling unit and at least one remote unit. The at least one second coupling unit in each remote cascaded chain is cascaded, and each remote unit is respectively connected to a corresponding second coupling unit. The first coupling unit transmits a radio-frequency signal transmitted by the extended unit to the second coupling unit. The second coupling unit transmits a radio-frequency signal of input power to the remote unit connected to the second coupling unit according to a coupling value. The remote unit adjusts the power of the radio-frequency signal from the input power to the output target power and output the adjusted radio-frequency signal.
