## Abstract

Methods, systems, apparatuses, and computer readable media for providing a network analysis system are disclosed. An example of a system for providing a network analysis system includes at least one satellite device configured to monitor wireless network traffic to determine at least one network communication event, generate an event message based on the at least one network communication event, and transmit the event message. The system also includes a controller device configured to receive the event message, determine an identity of at least one device communicating during the network communication event, determine a network status based at least in part on the identity of the at least one device, and provide the network status via an interface.
