It typically manifests as a sharp spike on monitoring tools and can cause line errors or even completely disrupt broadband connections.
This additional noise can overpower the ADSL signal, leading to reduced speeds or total loss of synchronization with the exchange.
For instance, the incident in Aberhosan (reported by BBC and CNN) involved an old television that, when turned on, emitted electrical interference in the frequency range used by the village’s broadband network, thereby disrupting the service.
[2] Detecting and identifying sources of electrical interference in telecommunications systems, particularly broadband networks, is a critical aspect of maintaining reliable communication services.
Field tests, including walkdowns or walkabouts with portable equipment such as spectrum analyzers, allow engineers to detect interference sources in real-time.
This approach is effective in cases where interference is related to the activation of household appliance or other electrical devices operating on timers.
Collaborative identification, engaging with local residents or users to gather information about the usage of electrical devices can be pivotal in identifying interference sources.
