Of late, network congestion is one of the most talked about topic in the telecoms industry has is attributed to the overwhelming growth in data consumption. According to Cisco, all around the world, mobile data traffic is expected to double every year through 2014. With such massive demands for data, industry stakeholders are looking at various measures to cope with the increase and mitigate congestion issues. There is an assortment of solutions to combat congestion, ranging from high investment to cost-effective and short-term to long-term. In this paper, Greenpacket puts forth a cost-effective, immediate and long-term solution to network congestion - data offloading. We examine a typical cellular operator's network structure, congestion points and total cost of ownership (TCO) and next, outline a calculation model (based on an Asia Pacific cellular operator) to demonstrate how much operators can save by offloading data to a secondary network such as WiFi. Data offloading directly impacts 36.5% of a network's TCO. As such, operators can potentially* save USD 14.4 million/year or USD 72 million over 5 years through data offloading.
