Abstract

Aspects of the subject disclosure may include, for example, receiving, by a network element of a distributed antenna system, a reference signal and a first modulated signal at a first carrier frequency, the first modulated signal including first communications data provided by a base station and directed to a mobile communication device. The element converts the first modulated signal at the first carrier frequency to the first modulated signal in a first spectral segment based on an analog signal processing of the first modulated signal and utilizing the reference signal to reduce distortion during the converting. The network element wirelessly transmits the first modulated signal at the first spectral segment to the mobile communication device. Other embodiments are disclosed.
