(English Abstract)
Ubiquitous makes it possible to expand a short-distant wireless communications infra and provide various services. Especially, it is very important to develop multimedia contents service technology through ZigBee and WPAN technology. But because the data transmission rate of IEEE 802.15.4 Standard ZigBee is low, there are many barriers for multimedia contents services. In this paper, to improve ZigBee that has the limitation of transmission rate in IEEE 802.15.4 Standard, an upgraded model to 1Mbps through MAC Layer remodeling is designed. And Zigbee-based broadcasting multimedia contents services system is designed and implementation to provide the service in Ubiquitous environment.
