日本欲打造隐形光纤:WiFi提速10倍

当然,我们也不用太过激动,因为这项新技术及其声称的速度还没有被同行评审过。不过,如果这项技术真的能够可行,这个发送器将是实现WiFi连接速度提升至目前的10倍的关键所在。

另外,要想理解为什么新的发送器会如此之快,我们需要了解一下WiFi的工作原理。简单地说,我们的路由器会将数据以电磁波的形式发送出去,手机、平板电脑和笔记本电脑等设备会在接收电磁波之后将它再转换成信息,这就是数码设备通过WiFi连接互联网的过程。电磁波有着不同的波长,而我们目前的发送器发出的电磁波的波段为千兆赫兹(GHz),标准路由器的波段在5GHz左右,高速局域网的连接则高达60GHz。一般情况下,频率越高,波长就越短,这也意味着更快的连接速度。

据报道,该日本团队已经能够发送波长小于一毫米的电磁波,它的频率在275到305GHz 这个范围内。值得一提的是,一旦电磁波的频率超过了300GHz这条界线的话,我们就进入了太赫兹波段。这个波段跟其他波段相比显得更加通畅,就像是在所有飞机的上方飞行一样。研究人员说,他们目前已经能够利用太赫兹波段在多个通道中实现100Gbps的数据发送速度。而随着技术的进一步完善,他们相信能够将这一速度提升到万亿比特/秒。

来自广岛大学的首席研究员Minoru Fujishima表示:“我们目前的无线数据速率通常为百万比特/秒,但是我认为我们很快就能够在太赫兹无线技术的帮助下实现大幅度提升,达到万亿比特/秒的级别。”

他补充道:“这种极端的速度目前仅存在于光纤中,我想把光纤的速度带来空气中,而我们已经朝着这个目标迈出了非常重要的一步。”当然,太赫兹波段的使用也存在一定的限制,除了短波发送器的开发工作很困难之外,这些高频信号的有效范围通常都比较小,并且穿透物体的能力也更弱。

虽然这项技术的实际应用仍然需要解决许多问题,但是我们知道发送器是由硅制成的,这意味着它可以很容易就集成到目前的技术中。
