The general term for this approach is Carrier Sense Multiple Access, or CSMA for short.

这种方法总称是载波侦听多路访问，简称 CSMA。

A satellite ping of her GPS coordinates provided by her carrier would make Laura a digital dot on their computer-screen street maps.

由劳拉载波提供GPS卫星声脉冲将使她成为一个小点，出现在他们脑屏幕上街道地图上。

When the 1.5 second computer wakes up a moment later, it’ll see the carrier is in use, and will wait for the other computer to finish.

片刻后 1.5 秒计算机醒来时，它会看到正在使用载波，并等待一台计算机完成。

Many computers can simultaneously sense the carrier, hence the “Sense” and “Multiple Access”, and the rate at which a carrier can transmit data is called its Bandwidth.

许多计算机可以同时感知载波，因此有“感知”和“多路访问”，而载体可以传输数据速率称为其带宽。

This circuitry shifts the carrier wave to a higher frequency when it wants to send a 1 or to a lower frequency when it wants to send a 0.

当路想要发送 1 时，它会将载波移至更高频率；当路想要发送 0 时，它会将载波移至更低频率。

Note that the comparison to a traffic light which emits one color and then another is a little inaccurate because your smartphone's circuitry generates one frequency, called a carrier wave.

请注意， 与发出一种颜色然后发出一种颜色交通信号灯比较有点不准确， 因为智能手机路会产生一种频率，称为载波。

To answer such naysayers a group of physicists at Fermilab have just submitted a paper to Modern Physics Letters A in which they describe how they have built themselves a neutrino-powered telephone.

为了消除类似质疑，费米实验室一群物理学家刚向物理学界权威杂志Modern Physics Letters A提交了一篇论文，论文中描述着他们怎样为自己成功定制了利用中微子载波无线通信话。
