CO-SITE INTERFERENCE IN RADIO NETWORKS
CO-SITE INTERFERENCE IN RADIO NETWORKS

Summary/Abstract: The radio spectrum is a limited national resource, essential for some governmental applications and increasingly important for a series of non-governmental applications. RF co-site interference has been around since the advent of wireless communications equipment and the problem is getting worse as the need for new RF/Microwave communication systems grow. It has become more important than ever to have an understanding of RF co-site interference, what the terms mean and what tools are available to address the problem. One thing is certain; RF co-site interference is not going away and will become worse over time as new wireless systems proliferate the environment. The article addresses the issue of radio resource allocation when using a large number of emission and reception sources for means of communication and non-communication in a small area. Locating several emission sources in the same site leads to different types of disturbing signals: emissions outside the bandwidth, harmonics and intermodulation. The article categorizes and describes these sources, presents the results of measurements distinguishing them, as well as the results of implementing some protective measures.
