Which of the following might indicate the presence of signal interference?

Signal interference can manifest in various ways that directly impact the quality and reliability of wireless communication. In the context of the options provided, both loud audio during calls and frequent disconnections can be clear indicators of such interference.

Loud audio during calls suggests that there may be unwanted noise or disruption interfering with the signal transmission. This could stem from radio frequency interference, where other electronic devices or signals are disrupting the clarity of the voice transmission.

Frequent disconnections are another common sign of signal interference. This situation typically occurs when the signal strength is compromised, causing the connection to drop unexpectedly. It might be due to obstacles in the environment or competing frequencies that reduce the effectiveness of the signal.

Thus, the combination of both loud audio and frequent disconnections serves as a comprehensive indicator of potential signal interference, making the choice that includes both A and B the most accurate response regarding identifying issues related to wireless communication quality. The option indicating that nobody reports issues would imply that there are no noticeable effects of interference, which contrasts with the presented indicators of signal problems.
