4G网络畅通使用有两难点

Category : 其他

4G网络使用有两难点,一是终端问题严峻,二是4G网络使用体验能否保障通畅。解决好这俩个问题,作为老牌无线通讯设备行业专家的伊林思科技有以下拙见:

首先,4G网络使用体验能否保障通畅。基站的建设只是网络建设的一部分,要实现完全无缝覆盖的4G网络还有一段时间,即使建设好了,全网的优化也还 需要时间。这也就意味着可能存在4G网络盲区或4G信号不稳定的情况,这时,用户将切换到3G或2G网络。目前来看除了联通的4G网络是由3G平滑过渡 的,可以很方便的进行切换保障用户的使用体验外,移动和电信将很难做到这一点。而一旦基站间切换不好,或者因为用户量大拥挤,移动的网络将切换回2G,电 信需要重新搜寻网络,对于用户使用体验来说简直是灾难。

其次,终端问题严峻。此前在3G时代,不论是中国电信还是中国移动,终端产业链 成熟度一度制约了其3G发展脚步。4G时代,对终端产业链提出了更高的要求,多模多频的手机成为焦点。在具体的手机终端方面,截至目前,TDD手机仅有 20多款,FDD手机140多款,还远远不能满足市场的需求最后,生态环境建设亟需跟上。3G时代,移动互联网获得了蓬勃发展,倒逼运营商走入流量经营的 探索。但是目前4G还只是一条简单的“高速公路”,还不存在真正的“杀手级应用”,目前各家运营商宣传最多的4G应用—“视频”,其实在3G时代已经实现。因而需要开拓明确具体的4G特色应用来塑造新的消费需求引领市场。

最后,致力于工业无线路由的伊林思科技希望3大运营商尽快优化4G网络。给工控行业来个效率上的提升!
