Active network management methods for ensuring live voice quality

Active management of a data network facilitates the high-quality live broadcast of captured digital audio from multiple client devices present in a venue. In various aspects, the system includes a network hub. The network hub transmits and receives data from a plurality of the client devices which may be personal mobile devices. A network manager component manages communications of the client devices with the network hub. The network manager uses measured dynamic network parameters and determines conditions for maintaining audio quality according to configurable rules. The dynamic network parameters may include device qualification(s), live measured audio quality of service metrics, and unwanted data packets. In various aspects, dynamic authentication and de-authentication of client devices as well as data transmission throttling of client devices are techniques utilized for active network management. The network manager maintains audio quality for the client device configured or selected to broadcast over the public address system.
