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

这种方法的总称是侦听多路访问，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.

由劳拉的供的GPS坐标的卫星声脉冲将使她成为一个小点，出现在他们电脑屏幕上的街道地图上。

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，它会看到正在使用，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.

许多计算机可以同感知，因此有“感知”和“多路访问”，而体可以传输数据的速率称为其带宽。

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.

当该电路想要 1 ，它会将移至更高频率；当该电路想要 0 ，它会将移至更低频率。

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， 与出一种颜色然后出一种颜色的交通信号灯的比较有点不准确， 因为智能手机的电路会产生一种频率，称为。

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.

为了消除类似的质疑，费米实验室的一群物理学家刚向物理学界权威杂志Modern Physics Letters A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的无线电通信电话。
