现代通信走过了数字化、综合化、光纤化的路子后,正向智能化、宽带化、个人化方向发展。人们对通信的需求已不再是仅仅打个电话,而是要求能在“任何时候、任何地点同任何人快速通信”。因此,实现多种通信媒体,多种通信手段,多种通信工具,一人一号的通信,是未来通信发展的必然趋势。
After the digital communication, integration and optical fiber have passed the modern communication, we are moving toward intelligent, broadband and personalization. The need for communication is no longer simply a phone call, but requires quick communication with anyone “anytime, anywhere.” Therefore, the realization of a variety of communication media, a variety of means of communication, a variety of communication tools, one number one communication is the inevitable trend of future development of communications.
