From the perspective of telecom industry, a brand-new "post-telecom era" is coming.

With the advent of 3G era and the development of mobile Internet, IT, Internet, media, telecommunications, retail and other industries are accelerating their integration and penetration, and the boundaries of industries are becoming blurred, gradually evolving into a brand-new industrial ecosystem. Telecommunications industry is the core of social and economic informatization, and the times are changing. The author tries to describe this change trend with "post-telecom era" and write down his own thoughts on this change with a pen tip.

In the post-telecom era, there are many new competitors in the telecom market, including emerging Internet companies, terminal manufacturers, radio and television operators and so on. Competition has further intensified. How can traditional operators expand their living space, innovate their business models and get a reasonable return on investment in the process of reform? This is the content of this book.
