Abstract:BroadbandWirelessAccess(BWA) has become one of the major directions for the evolution of both broadband access and mobile communications. However, some difficulties emerged during application and industrialization of BWA systems, which call for typical service models, technology innovations and backbone support from broadband Internet. A Broadband Wireless Multimedia (BWM) system is proposed in this paper. The system aims at a new-type “triple-play” BWA network by using the broadband Internet as the core network platform and integrating the terrestrial digital TV broadcasting system and the BWA system with the proprietary intellectual property rights. According to the latest research results, the BWM system is an effective solution to the existing difficulties of BWA systems. Moreover, it is competence in service provision, service coverage, frequency planning, terminal power consumption and cost for network building.
