OFDMA is based on the idea of frequency-division multiplexing, which is a method to transmit multiple data streams over a channel.

OFDMA是根据频分多路传输系统的思想，这是一种在一个频道上传输多个数据流的方法。

In wireless technology, collision occurs when two transmitters transmit at the same time with the same modulation scheme on the same frequency.

在无线技术中，冲突发生在两个发射器在相同的时间、相同的频率发送相同的调制方式。

These leads will have to be sufficiently short to transmit very high frequency signals, which tend to radiate away as microwaves if the lead is too long (by 2015, chips will work high in the gigahertz band).

ADS-B promises to make air traffic control easier, cheaper and in many ways safer by allowing planes to transmit their locations by radio frequency instead of depending on towers to use radar to track and coordinate them.
