We study magnetic fluctuations at sub-ion scales and down to sub-electron scales using Helios/SCM measurements in the inner Heliosphere and Cluster/STAFF data at the Earth's orbit. Using these data we test the generality of the kinetic spectrum at different radial distances from the Sun. Then, in the time domain, and using the wavelet transform, we study the nature of magnetic fluctuations, which form the kinetic spectrum. Finally, we plan to comparer our results with the Parker Solar Probe/FIELDS measurements in the inner Heliosphere.
