Abstract
An OFDMA scheduling device receives a data stream from a network router and can identify audio packets based on metadata. The OFDMA scheduling device is aware of the number of the wireless devices connected to it, and can determine a resource unit (RU) allocation for each of the wireless devices based on the payload of the wireless devices. The OFDMA scheduling device can also determine a modulation and coding scheme (MCS) for each of the wireless devices based on the received signal strength indicator (RSSI) value and any feedback data received from each of the wireless devices. Based on the RU allocation and MCS determination, the OFDMA scheduling device can send a downlink OFDMA frame to the wireless devices, notifying them of their respective RU allocations and the MCS to be used while receiving audio packets from the OFDMA scheduling device.
