5G广播,eMBMS,FeMBMS,三网融合在3GPP Release 14 中提出的FeMBMS 是对3GPP Release 14 前版本中eMBMS 的进一步演进.相较于eMBMS 中最多60%的无线资源可用于广播业务,FeMBMS 中接近100%的无线资源可用于广播业务.FeMBMS 是迄今第一个提出利用传统的高功率高塔(HPHT)等广播基础设施提供地面广播服务的移动通信技术...
第四,应用要求高。5G之前的eMBMS,需要内容提供商、终端侧、网络侧都需要配合,应用起来比较麻烦。 场景需求不强烈,网络部署成本高,应用不方便等都制约了eMBMS的发展。需求不强烈,应用少,而网络成本高,运营商没有意愿部署广播能力;网络能力不具备、应用要求高,导致广播业务创新无法进行。这成了一个循环,所以eMBMS的广播...
All spotlights are on the latest generation of mobile communications 5G lately and talk about 6G has already emerged. There have been tons of interest on the subject of broadcasting radio and TV channels in 5G. The implications will undoubtedly be enormous when millions of smartphones and tablets...

在高速发展的移动互联网和不断增长的物联网业务需求共同推动下,要求5G(5thgenerationmobilenetworks)具备低成本、低能耗、安全可靠的特点,同时传输速率提升10到100倍,峰值传输速率达到10Gbit/s,端到端时延达到毫秒级,连接设备密度增加10到100倍,流量密度提升1000倍,频谱效率提升5到10倍,能够在500km/h的速度下保证用...
而eMBMS(Evolved MBMS)是3GPP Rel-9协议提出的应用在LTE网络上的增强型广播多播技术,支持更大的带宽,能提供更多的频道和更流畅的多媒体内容,用户体验也更好。eMBMS能够显著地降低运营商在LTE网络上同时向多个用户提供诸如视频、音频等高带宽内容的成本。在Rel-10中,eMBMS新增了计数(counting)功能和接纳控制(admission...
针对LTE的演进多媒体广播多播服务(eMBMS:Evolved Multimedia Broadcast Multicast Service),主要目标是:指定使用长循环前缀(例如大于33.33µs)的方式,以在用于大型SFN时延扩展环境(例如15km或更大的站点间距离)的混合单播/eMBMS载波中使用,从而确保在同一载波上共存传统前缀和新前缀,同时实现至少2 bps/Hz的频谱效率。
