WebRegions with higher concentrations of ions and free electrons occur at several different altitudes and are known, as a group, as the ionosphere. There are three main regions of the ionosphere, called the D layer, the E layer, and the F layer. WebThe 'F2' layer plays a major role in the ionospheric propagation of radio waves of the HF spectrum.
