<p>The present invention relates to a fronthaul system having improved transmission efficiency between separable base stations and equipment thereof and, more particularly, to a fronthaul system which improves transmission efficiency in base stations separated into a digital unit and a radio unit to effectively process data load. According to the present invention, the separable base station converts a transceiving signal into an intermediate frequency (IF) signal, and transmits a feedback signal of a power amplifier at the same time, instead of transmitting a digital signal by using the standard such as a common public radio interface (CPRI) and the like, in order to improve the transmission efficiency and simplify a structure of the radio unit (RU), thereby effectively processing the amount of data transmission which significantly increases between the radio unit (RU) and the digital unit (DU) or between integral base stations including the same, and effectively reducing costs for network construction and maintenance.</p> |
