We present an overview of wave observations obtained onboard the four Cluster
satellites using the Electric Field and Wave Experiment (EFW) in cooperation with
the Spatio-Temporal Analysis of Field Fluctuations (STAFF) experiment. We
concentrate on phenomena at frequencies from essentially static fields, up to 180 Hz.
Observations from different regions of the magnetosphere and the magnetosheath
are investigated. In particular we compare wave phenomena observed by four
satellites separated by distances of the order of thousand kilometers. The degree of
coherence between observations at different satellites is investigated. The
observations are also used to investigate energy transport in the magnetosphere.
