随着智能终端的兴起及无线数据应用业务的丰富,无线通信系统中的数据用户数大幅增加,数据内容不再限于传统的文字或者图像,未来用户对高清晰度视频、手机电视等多媒体业务的需求越来越多,导致无线网络流量呈现出爆炸式增长的态势。根据市场机构预测,未来10年,无线数据业务将增长500~1000倍,平均每年增长1.6~2倍,这对无线通信系统的网络容量提出了更高的要求。
面向未来,移动互联网和物联网业务将成为移动通信发展的主要驱动力。第五代(5th Generation,5G)移动通信系统将满足人们在居住、工作、休闲和交通等多种区域的多样化业务需求,即便在密集住宅区、办公室、体育场、露天集会、地铁、快速路、高铁和广域覆盖等具有超高流量密度、超高连接数密度和超高移动性特征的场景,也可以为用户提供超高清视频、虚拟现实、增强现实、云桌面和在线游戏等极致业务体验。与此同时,5G还将渗透到物联网及多种行业领域,与工业设施、医疗仪器和交通工具等深度融合,有效满足工业、医疗、交通等垂直行业的多样化业务需求,实现真正的“万物互联”。
