This is probably this probably consumes 30 watts, 30 joules per second is my rough guess.

产生误差的平均速度是每秒4米。
The average speed for errors was 4 meters per second.

在给定信号强度和噪声水平的情况下,以比特每秒为单位给出的最终限制是无差错通信的最大绝对速率。
The resulting limit, given in units of bits per second, is the absolute maximum rate of error-free communication given signal strength and noise level.
