其实世界上还没出现真的4G.
In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabit per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users)
2008年3月,国际电信联盟无线电通信部门(ITU-R)为4G标准的要求指定一组命名的高级国际移动通信(IMT-Advanced的)规范,设置4G服务在100兆比特每秒峰值运算速度要求第二个(兆位/秒)移动通信(如火车和汽车)和每秒1千兆位(Gbit / s的)为低移动通信(如行人和固定用户)
Since the first-release versions of Mobile WiMAX and LTE support much less than 1 Gbit/s peak bit rate, they are not fully IMT-Advanced compliant. (from wikipedia)
由于移动WiMAX和LTE支持1 Gbit / s的峰值速率远低于第一个发布版本,它们并不完全符合IMT-Advanced的标准。 |
