Abstract:munication to the development of society and people' s lives have a huge impact. Back in the seventies, people began to study the munications. In contrast with the wired munication, munication has not set up a transmission line cable, from the distance constraints, transmission distance, communication and flexible benefits, and fiber optic technology, wireless technology, multimedia technology, synchronous digital hierarchy (SDH), Asynchronous Transfer Mode (ATM), software technology to these new Our technology-based information infrastructure construction, human society will advance to the information age. This article analyzes the advantages and disadvantages of radio, and explore the future development trend of munications
Key words:munications technology;Trend
