Operators of 4G-LTE cellular data networks face an uphill battle against rapidly increasing data usage and declining ARPU. Increased sales of iPhones, Android smartphones, tablets, and notebooks with embedded 3G/4G capabilities are all taxing the macro networks for scarce capacity resources. This exponential growth of data traffic is forcing operators to evaluate mid to long term migration strategies to LTE while in need of short term strategies to relieve their congested macro networks. On top of these clear and present dangers to the day-to-day operations of the network, operators are faced with increased scrutiny from shareholders to prove that a pure LTE overlay deployment will provide a positive ROI as well as an improved customer experience.
