Abstract
A base station system for mobile communication between a mobile terminal and a base station controller, the base station system utilizing a digital modem unit for receiving a signal to be transmitted to the mobile terminal from the base station controller, framing the received signal according to a frame format for transmission different than an Ethernet specified data format, the frame format being a predetermined remote RF (radio frequency) unit frame, the digital modem unit transmitting a plurality of the remote RF unit frames in series over an Ethernet using twisted pair cable, at least one remote RF unit hub receiving the remote RF unit frames transmitted by the digital modem unit and distributing the received remote RF unit frames to a plurality of remote RF units via the Ethernet using twisted pair cable, and the plurality of remote RF units producing a deframed signal by deframing the remote RF unit frames received from the remote RF unit hub, modulating the deframed signal to an RF signal, and transmitting the RF signal to the mobile terminal, wherein the remote RF unit frames are divided into a traffic frame for use in transmitting traffic data, which is transmitted and received by the mobile terminal and a control frame for use in transmitting a control address and control data, the control address differentiating the plurality of remote RF units from one another, the control data containing a command to control operation and functions of the plurality of remote RF units.
