What is 'interference' in wireless communications?

Interference in wireless communications refers to an external signal that disrupts the transmission of data. This disruption can result from various sources, such as other electronic devices, physical obstacles, or even environmental factors that negatively impact the intended signal. When interference occurs, it can lead to diminished signal quality, increased error rates, and reduced overall performance of the communication system.

Understanding interference is crucial for professionals in the field, as it affects the reliability and efficacy of wireless networks. Identifying and mitigating interference sources—such as using frequency selection, adjusting power levels, and implementing better antenna designs—are key strategies in maintaining optimal communication performance.
