All electronic devices generate what is called “radio noise” in the form of unwanted random emissions that can create low level of interference to radiocommunications systems. It can be considered as a form of pollution of the radio spectrum that degrades the performance of radio receivers. The increasing use of electronic devices in everyday life means that radio noise will likely also be increasing.
It is important to quantify radio noise and understand its impact on spectrum users. This report provides an update on Ofcom’s ongoing radio noise measurement campaign. Our campaign focuses on radio noise in indoor environments, and the comprehensive approach we have undertaken makes this study the first of its kind in the UK and beyond.
One of Ofcom’s principal responsibilities is to secure the efficient use of spectrum in the best interests of all UK consumers and enabling wireless services in the wider economy as set out in our Plan of Work. This requires an in-depth understanding of spectrum use in the UK and how certain factors such as radio noise including unwanted emissions can have an impact on its quality.
