ABSTRACT
Today’s mobile operators are facing a strong competition environment. The cost to build, operate and upgrade the Radio Access Network (RAN) is becoming more and more expensive while the revenue is not growing at the same rate. With the rapid adaptation of wide screen smart phones in the market, the mobile Internet traffic is surging, while the ARPU (Average Revenue Per User) is flat or even decreasing slowly, which impacts the ability to build out the networks and offer services in a timely fashion. To maintain profitability and growth, mobile operators must find solutions to reduce cost as well as to provide better services to the customers.
