A high Bit Error Rate (BER) is often a direct consequence of poor connections within a network, and ingress is a significant factor contributing to this issue. Ingress refers to unwanted signals from external sources entering a communication system, which can disrupt the integrity of the data being transmitted. This interference can manifest as noise, leading to an increased likelihood of errors in the received data.

When there are poor connections, such as loose cables or corroded connectors, ingress can more easily affect the signal quality. The unwanted signals can introduce distortion and noise that degrade the clarity of the received data, thereby increasing the BER. This results in more bits being received incorrectly, impacting overall network performance and reliability.

Bandwidth, frequency modulation, and echo can also affect communication systems, but they do not directly correlate as strongly with issues stemming from poor connections as ingress does. Bandwidth pertains to the capacity of the transmission medium and does not inherently create errors due to poor connections. Frequency modulation involves the method of transmitting data and may not be influenced by the quality of the physical connections in the same way. Echo, primarily a result of reflections in the transmission medium, can create confusion in signal interpretation but is less directly related to connection quality compared to ingress.
