时代在变,用户的需求也在发生变化,运营商提供服务的范围、方式与程度也应该随之变化。对运营商而言,4G带来的变化主要体现在通信网络上。一是网络速度更快。4G网络支持100Mbps~150Mbps下行带宽,速度是TD-SCDMA的35倍,是WCDMA的14倍。二是通信质量更高。4G时代对高速数据和高分辨率多媒体服务的支持远高于3G时代,通信品质也有所提升。三是网络更加智能。可以实现网络的智能疏导、管控和分发等智能管道能力,使差异化服务成为可能。
Times are changing and the needs of users are changing. The scope, methods and degree of service provided by operators should also change accordingly. For operators, the changes brought by 4G are mainly reflected in the communications network. First, the network faster. 4G network supports 100Mbps ~ 150Mbps downlink bandwidth, speed is 35 times of TD-SCDMA, is 14 times of WCDMA. Second, higher quality of communication. 4G era of high-speed data and high-resolution multimedia services support much higher than the 3G era, communication quality has also improved. Third, the network is more intelligent. It can realize intelligent pipeline capabilities such as intelligent grooming, control and distribution of networks, and make differentiated services possible.
