WIDEBAND REMOTE UNIT FOR DISTRIBUTED ANTENNA SYSTEM
First Claim
1. A method comprising:
- receiving, via an uplink path of a wideband remote unit of a distributed antenna system, wideband signals comprising an uplink RF signal and a leaked downlink RF signal, the uplink RF signal having an uplink signal power and the leaked downlink RF signal having a downlink signal power greater than the uplink signal power, wherein the leaked downlink RF signal is from a downlink RF signal transmitted by the wideband remote unit;
converting, by the wideband remote unit, the received wideband signals to a first digital RF signal that represents the uplink signal and to a second digital RF signal that represents the downlink signal; and
transmitting, by the wideband remote unit, the first digital RF signal and the second digital RF signal to a unit of the distributed antenna system in communication with a base station.

Abstract
Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.
