摘要
华数依据NGB的发展要求,以传统广播电视大带宽、高速率、广覆盖特点为依托,辅以U频段无线双向技术,以建设有线、无线、卫星互联互通和智能协同覆盖网络为目标,面向广电网络一体化业务需求,重点研究有线无线融合接入技术,创新性地提出NGB-W双向交互信道技术,以广播大塔与交互小塔的协同覆盖、广播与双向交互业务协同传输的方式构建NGB-W一体化无线网络,合理实现有线电视网络、无线广播网、无线宽带数据网的优势互补,为实现广播电视网向广播电视数据网的发展演进提供技术支撑。
The Wasu on the basis of the development of NGB, with large bandwidth, high speed, wide coverage characteristics of traditional radio and television as the basis, combined with U wireless technology to build a two-way, wired, wireless and satellite interconnection and intelligent cooperative overlay network as the goal, the radio and televi- sion network integration business needs, focus on the integration of wired and wireless access NGB-W technology, pro- posed two-way interactive channel technology innovation, construction of the integration of NGB-W wireless network to broadcast tower and tower interactive collaborative coverage, broadcasting and two-way interactive service coopera- tive transmission, reasonable to achieve complementary advantages of the cable TV network, wireless network, wireless broadband data network, to achieve the development of radio and television networks to broadcast television data net- work, provide technical support.
