Abstract
Aspects of the subject disclosure may include, for example, receiving, by a network element of a distributed antenna system, a reference signal, an ultra-wideband 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 instructions in the ultra-wideband 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. The reference signal is received at an in-band frequency relative to the control channel. Other embodiments are disclosed.
