US 2003/0152057 A1 · Temporal alignment of CODEC data with wireless local area network RF slots

Abstract

A wireless local area network (WLAN) transceiving integrated circuit services voice communications in a WLAN with at least one other WLAN device. The WLAN transceiving integrated circuit includes a WLAN interface, an input buffer, a transcoder, and a processor. The WLAN interface wirelessly communicates with the at least one WLAN device to receive packetized audio data from the at least one WLAN device. The input buffer operably couples to the WLAN interface and receives the packetized audio data from the WLAN interface. The transcoder operably couples to the input buffer and receives the packetized audio data from the input buffer. The transcoder converts the packetized audio data to Pulse Code Modulated (PCM) audio data and outputs the PCM audio data to a coupled audio COder/DECoder (CODEC). The processor operably couples to the WLAN interface, the input buffer, and the transcoder. The transcoder outputs the PCM audio data to the audio CODEC such that the PCM audio data is substantially temporally aligned with Radio Frequency (RF) slots of the WLAN interface.
