在移动环境中,3G/WLAN网络双模终端可提供无处不在、带宽可变、服务质量(QoS)可保证的多种高速率业务。
In a mobile environment, 3G/WLAN dual-mode terminals can provide a wide range of services at high rate with variable bandwidth and Quality of Service (QoS) assurance.
因为带宽是唯一重要的可变因素,所以没什么机会可以将这种传送适应用户的连接能力。
Because the only significant variable is bandwidth, there is little opportunity to tailor the delivery to the user's connection capabilities.
无所不在,即时连接,可变带宽。
