What can signal interference lead to in telecommunications systems?

Signal interference in telecommunications systems can lead to decreased customer satisfaction because it negatively impacts the quality and reliability of the service provided. When interference occurs, it can cause dropped calls, poor voice quality, slow data speeds, and connection issues. As a result, users experience frustration and inconvenience, leading to a lower overall satisfaction with the service.

Increased data transfer speeds and improved network reliability are counterproductive outcomes in the context of signal interference. Interference disrupts communication rather than enhancing it, thus leading to a poorer experience for customers. None of the options suggesting that interference could provide beneficial effects, such as improved reliability or increased speeds, are valid in this scenario.
