为用户提供其所需无线容量,是当今一大技术挑战,也是一个需要兼顾各技术的议题。

我们需要更广阔的频谱,还要充分利用所有的频谱类型——既包括授权频段,也包括非授权频段。一项重要解决方案就是LTE Unlincensed(非授权频段LTE),即通过多种技术聚合,将4G LTE的优势扩展至非授权频段。

不同于授权频段主要供指定用户使用,非授权频段是一种任何人都可以用来部署无线通信系统(只要满足监管要求,如电力等)的无线电波。包括各类系统,如Wi-Fi、蓝牙、无线电话和车库门遥控开关,其中大部分使用的是2.4 GHz波段。

非授权的LTE将使用5GHz非授权频段,并与Wi-Fi新变体分享。该技术在5GHz频段下众多可用的非授权渠道中进行选择,从而避开Wi-Fi用户。但在非授权LTE和Wi-Fi必须共享同一信道的非典型情况下,两种技术也可以和平共存。

这个技术可以通过图表展示,但我们觉得,由一群世界级的杂技演员来演示的话,会更有趣。
