With the rapid development of wireless broadband communication and the swift progress in the Internet industry, mobile Internet is showing a booming trend with its unprecedented way to change people’s social lives and lifestyles, and it has become one of the necessary means for modern human information interaction. Traditional wireless communication is mostly based on ground-based cellular communication. However, 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 developing rapidly. The resulting space–air–ground integrated mobile Internet will become an information bridge for human beings to understand, enter, use, and develop space in the future.

Since the birth of wireless communication, the shortage of spectrum resources has been the biggest bottleneck restricting its development. The efficient use of spectrum resources and the development of the corresponding spatial multidimensional cooperative transmission technology have brought new growth points for future wireless communication and also provided theoretical and technical guarantee for the healthy development of the space–air–ground integrated mobile Internet in the future. This chapter will outline the characteristics and development history of ground-based, air-based, and space-based wireless communication.
