Lasers also offer far higher data rates than radio waves.

激光提据传速率也远高于无线电波。

It was like the equivalent to one kilobit per second modem.

这就像是一个每秒传速率为1千比特调制解调器。

A CD, just for comparison, is a little over 1,400 kilobits per second.

一张CD，仅作比较，传速率略高于每秒1,400千比特。

It also poses challenges because we don't have the same sort of data rate or bandwidth available.

这也带来了挑战，因为我们在水下无法获得与陆地上相同据传速率或带宽。

So, basically, TCP can handle out-of-order packet delivery, dropped packets – including retransmission – and even throttle its transmission rate according to available bandwidth.

所以，基本上，传控制协议可以处理乱序据包投递、丢失据包——包括重传——甚至可以根据可用带宽调整其传速率。

A different method that has higher data transfer rates is called phase shift keying, which is significantly more complicated to explain, but we'll try.

另一种具有更高据传速率方法称为相移键控，这种方法解释起来要复杂得多，但我们尽量说明清楚。

Researchers in China recently showed that, using a one-watt LED bulb, li-fi could connect four computers to the Internet at data transfer rates up to 150 megabits per second.

最近中国研究者们发现, 使用一个1瓦特LED灯泡, li-fi就可以以带宽150兆/秒传速率连接4台电脑接入互联网。

There's a UHF that has low data rates and that's for basic commands and telemetry communication and then an S Band which is for higher data rates like actually transmitting the pictures.

有一个UHF频段，据传速率较低，用于基本命令和遥测通信，然后是S频段，用于较高据传速率，比如实际传图片。

In order to avoid wasting power from your smartphone's battery, the frequency and resulting data transfer rates across the network on a chip ramp up and down depending on the requirements of the applications you're running.

为了避免浪费智能手机电池电量，芯片上网络频率和相应据传速率会根据你运行应用需求进行上调或下调。

Also, note that on the DRAM packaging are its capacity in gigabytes, the number of millions of data transfers per second, which is two times the clock frequency, and the peak data transfer rate in megabytes per second.

另外，请注意在动态随机存取存储器包装上会标注其容量（以GB为单位）、每秒据传次（该值是时钟频率两倍），以及峰值据传速率（以MB/秒为单位）。
