Abstract
Determining noise levels in frequency band(s) for communications paths in distributed antenna systems. Noise may be induced in communications paths in distributed antenna system as a result of electromagnetic interference from communications media located in close proximity and/or from other electronic devices. Noise induced on communications media may not be evenly distributed across the frequency spectrum, but instead concentrated in certain portions of the frequency spectrum. The frequency band(s) of communication signals distributed in the distributed antenna systems may be adjusted to be provided outside of frequency band(s) having unacceptable noise levels. In this manner, the communications performance (e.g., the signal-to-noise (S/N) ratio) of communications signals communicated in the distributed antenna systems may be improved.
