The IEEE 802.15.4 LR-WPAN specifies low cost, low energy, low rate transmission of 20~250 kbps and mostly within 10 meters of diameter. Its specification of PHY and MAC layers can be used as the lower layers of ZigBee technology. As many applications for short range, wireless networking environment have been developed, the need for voice transmission over the IEEE 802.15.4 LR-WPAN has been also increased. This paper studies the possibility and effectiveness of voice transmission over the IEEE 802.15.4 LR-WPAN by intensive simulations using ns-2 simulator, and shows several use cases as its applications by their implementations.
