The results of this internationally supported new generation of wireless Internet are much more significant than most people would imagine,as the steps forward are much greater than the case between previous generations of wireless systems.Whereas between 2G and 3G wireless systems the rate of data transfer barely rose a few Kbps (千字节每秒) and was accompanied by few other major advances.With the arrival of the latest generation the bar (缓冲地址暂存器) has been raised several Mbps (兆比特每秒) and furthermore several other advantages have been presented.It means that the fourth generation mobile users will be able to capture signals in a broader variety of locations and circumstances,not being cut off simply because they have hopped from one network to the next.
Ultimately,the fourth generation mobile Internet means a vast readjustment(再调整) in the way people live their personal and professional lives,offering them the kind of mobility that they have always hoped for.And as the fourth generation capabilities are spread over increasing parts of the country,starting in the nation's largest cities and spreading out wards from there,it will in the near future be possible to roam from coast to coast without losing one's connection for even a second.
