DETERMINING NOISE LEVELS IN FREQUENCY BAND(S) IN DISTRIBUTED ANTENNA SYSTEMS AND ADJUSTING FREQUENCY BAND(S) OF COMMUNICATIONS SIGNALS IN RESPONSE, AND RELATED COMPONENTS, SYSTEMS, AND METHODS

摘要

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 are therefore adjusted to be provided outside of frequency band(s) having unacceptable noise levels. Using frequency bands outside of high noise level bands improves system performance (e.g., the signal-to-noise (S/N) ratio) in the distributed antenna system.
