| Abstract: The wireless communication is highly deployed due to it convenience of mobility. The wireless local area network, WLAN is dominated by IEEE802.11 standard. Wired local area network (LAN) is the network backbone of the WLAN. Almost all the new desktops’ motherboard are equipped with the Ethernet connecter and all new notebooks are equipped will IEEE802.11 WLAN. This evoked us to develop a wireless audio transceiver that compatible with IEEE802.3 and IEEE802.11 protocols. The VHDL modelling is done to model transceiver that convert the audio signal to IEEE802.3 packets to be transmitted through IEEE802.3 and IEEE802.11. The VHDL is selected to model the transceiver and VHDL is defined in IEEE as a tool of creation of electronics system because it supports the development, verification, synthesis and testing of hardware design, the communication of hardware design data and the maintenance, modification and procurement of hardware [1]. The transceiver consists of two individual modules, the transmitter and the receiver. The original audio signal is segmented to UDP packets that compatible with the IEEE802.3 protocol. The audio packets are broadcasted out through wireless access point (AP). After the audio packets received by the wireless clients through IEEE802.11 and IEEE802.3, the receiver will convert the audio packets back to audio signal. By broadcasting the data packets, all receiving speakers will be able to receive the data packets and convert the digital bits into audio wave. This gives the user the flexibility to place as many speakers as they want. The Cyclic Redundancy Check algorithm is not included in the transceiver because audio steaming is real time application, there is always not enough time to retransmit the audio packets that are corrupted. The proposed transceiver achieves 12kbps and sufficient to support audio streaming. | ||||
