VHDL modelling of the wireless audio transceiver through IEEE802.3 and IEEE802.11

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.
