Optimization of coverage and capacity of Self-Organizing Network in LTE

The Self-Organizing Network (SON), introduced as part of the 3GPP Long-Term Evolution (LTE) is a key driver for improving Operation and Maintenance (OAM) of the mobile networks. The goal of SON is to simplify the network management by auto-configuration and auto-optimization. Optimization of coverage and capacity is one of the high-level SON use cases. This paper provides some background of SON principles and presents a model that illustrates the SON optimization of coverage and capacity. Based on input parameters, better coverage in this model is ensured by automatic adjustment of antenna tilt.
