REMOTE ACCESS UNIT AND OPTICAL NETWORK FOR BIDIRECTIONAL WIRELESS COMMUNICATION USING THE SAME

摘要

A remote access unit and an optical network for bidirectional wireless communication using the unit are provided to separately amplify time division channels and frequency division channels to combine or transmit the amplified channels, thereby suppressing generation of nonlinearity of an active element caused by leakage of downlink signals. A remote access unit(300) comprises the followings. An antenna(340) wirelessly transmits downlink data, and inputs wirelessly received uplink data to the inside of the remote access unit(300). A switch(370) outputs downlink time division channels divided among the downlink data to the antenna(340), and receives uplink time division channels divided among the uplink data inputted through the antenna(340). A controller(301) controls the switch(370), in order that the downlink time division channels are not overlapped with the uplink time division channels.
