Abstract
Systems and methods are disclosed for operating a wireless audio network including a plurality of wireless microphone units (e.g., wireless delegate units) and a central access point having a mixer. The wireless microphone units may perform voice detection and level sensing, and make a preliminary gating decision. The central access point may make a final gating decision, determine the granting of wireless communications channels, and generate a final mixed audio output signal.

1-20. (canceled)
A wireless audio system, comprising:a plurality of wireless microphone units each configured to:determine a preliminary gating decision based on at least an audio input signal;and wirelessly transmit an access request based on the preliminary gating decision,wherein the access request is for requesting a grant of a wireless communication channel;and a central access point in wireless communication with the plurality of wireless microphone units, the central access point configured to grant the wireless communication channel for a selected designated wireless microphone unit of the plurality of wireless microphone units, at least partially based on at least one access request received from at least one of the plurality of wireless microphone units.
A wireless microphone unit configured to:detect an audio input signal;determine, based on at least the audio input signal, a preliminary gating decision;
- andresponsive to the preliminary gating decision being a positive gating decision, wirelessly transmit an access request to a central access point, the access request for requesting a grant of a wireless communication channel between the wireless microphone unit and the central access point.
A central access point configured to:wirelessly receive at least one access request from at least one of a plurality of wireless microphone units, wherein the at least one access request is for requesting a grant of a wireless communication channel between the at least one of the plurality of wireless microphone units and the central access point, and wherein the at least one access request is wirelessly transmitted from the at least one of the plurality of wireless microphone units based on a preliminary gating decision determined based on at least an audio input signal detected by the at least one of the plurality of wireless microphone units;
- andgrant the wireless communication channel for a selected designated wireless microphone unit of the plurality of wireless microphone units at least partially based on the at least one access request received from the at least one of the plurality of wireless microphone units.
