In a SON, a new femtocell added to a micro-network actually learns from the other femtocells already on that network – optimizing its own implementation without requiring manual installation. The femtocells on a SON are in constant communication, and they autonomously can recognize and adapt to changing environmental situations, maintaining a high level of quality of service (QoS). Because there are multiple femtocells on the micro-network in communication, if one goes down, there are three or four nearby that become aware of this environmental change and instantly can pick up the lost coverage. Thus, a SON femtocell micro-network offers a robust solution with built-in redundancy.
