Traditional wireless communication mainly uses ground-based wireless communication systems. However, with the rapid development of wireless communication systems, it is increasingly requiring higher spectrum utilization, greater system capacity, more flexible network coverage, and lower construction costs. With the continuous improvement of aerospace technology and the rapid growth of the types and quantities of space-based and air-based platforms, the space–air–ground integrated information network consisting of satellites, stratospheric balloons, and various aerospace vehicles is developed. This chapter mainly summarizes the characteristics and development process of the ground-based, air-based, and space-based wireless communication systems. In the following chapters, we will elaborate on the space–air–ground integrated cooperative transmission theories and key technologies.
