Who is primarily responsible for the majority of ingress?

Ingress refers to unwanted signals or noise that enter a communication system, which can severely impact data quality, cause disruptions, and degrade overall performance. The customer is primarily responsible for the majority of ingress because many common sources of ingress can be traced back to the customer's environment.

For instance, customers often have various devices within their premises, such as wireless networks, antennas, and electronic equipment, which can generate interference. Additionally, improper installation of customer-end equipment, such as faulty connections or inappropriate cabling, can also introduce ingress. Environmental factors specific to the customer's location, such as nearby sources of electromagnetic interference, further contribute to this issue.

While service providers, equipment manufacturers, and installation technicians all play significant roles in ensuring a quality installation and minimizing ingress, it is ultimately the customer’s responsibility to maintain their environment and equipment to reduce potential sources of interference.
