Ionosphere and communication
WebRadio Communication and the Ionosphere. The ionosphere is a region in the upper-atmosphere that meets space (exosphere). A mixture of free electrons and ions (known as "plasma") is created when solar radiation ionizes gases 80 to 600 km above the surface of the earth. The high densities of free electrons significantly affect radio communication. Webionosphere is used for radio communication and navigation asitreflectslong,medium,aswellasshortradiowaves.
