Abstract
Aspects of the subject disclosure may include, for example, receiving, by a network element of a distributed antenna system, a clock signal, a control channel 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 clock signal synchronizes timing of digital control channel processing by the network element to recover instructions from the control channel. The instructions in the control channel direct the network element of the distributed antenna system to convert the first modulated signal at the first carrier frequency to the first modulated signal in a first spectral segment. Other embodiments are disclosed.
