Abstract
In this paper, the energy saving on mobile communication repeater is studied. DB(Dual Band) small repeater, which is currently used in the field for indoor coverage, is adopted as a test unit. For reducing the power consumption, PFC (Power Factor Correction) is included on SMPS (Switching Mode Power Supply) of the DB small repeater. The test results show that approximately 38.9% of the power consumption is reduced comparing with the repeater without PFC. It means that approximately 230.43kWh per unit can be saved annually.
