摘要
This paper generalizes the previous mobile communication systems from the first generation to the thirdgeneration, and presents the requirements of the future fourth generation mobile communication system (4G). Thenthe Internet-based 4G system is presented, which breaks through the close structure of the traditional ones. Finally,the key technologies of the Internet-based 4G system are discussed.
