Model of Wireless Telecommunications Network Infrastructure Sharing & Benefit-Cost Analysis

China has entered a new era of Mobile Internet. There is a growing need for operators to drive down cost of capital assets or infrastructure deployed for telecom services. This has been expressed in recent times by many operators, on basis of mutual, agreements, to consider sharing infrastructure. This study aims at exploring the value of infrastructure sharing as a means of achieving cost efficiency and revenue assurance. The study seeks to explore the five principal network infrastructure sharing models, and build a mathematical model to analyze the Benefit-Cost of the infrastructure sharing as well as recommend an improved or enhanced framework and give some theoretical suggestion.
