  As wireless systems grow rapidly worldwide, one of the most important things,
wireless systems designers and service providers faces is interference.
Interference decreases coverage, capacity [1], and limits the effectiveness of
both new and existing systems. It is very difficult to avoid because wireless
communications systems must exist together in extremely complex signal
environments. These environments are consisting of multiple operating wireless
networks [2]. At the same instant, new technologies and signal sources in
Wireless Local Area Networks (WLANs) and digital video broadcasting are
jeopardized to wireless communications service. This article provides a survey
and analysis of interference in Wireless Network and provides a taxonomy.
