CB Radio

We often think, what if all the satellites and communication towers shuts down? There are few ways to still communicate and find out what’s going on around nearby area. Some of you might know what CB radio is, but those of you who don’t know what it is may question. How does it work? And don’t we need satellites or towers to communicate? The answer is no, we do not need satellites or towers. This old technology only uses an antenna which gets the signal out and the other is a receiver, which scrambles a signal from the antenna. People in today’s society still use this technology, people who travels a lot outside of a network area. So, this technology is also effective even though some people might have never used it.

Here is a link of a short video, that shows how CB radio works.

  1. The fact Citizens' Band radio or CB is still in use today shows that some of the "old" technology is still relevant today. A short range form of communication which can be used by anyone with the right equipment. The advancements in technology have made the CD smaller and increased the range and number of channels. Mostly used by truckers and emergency personnel. There is a culture of people who communicate through the CB. CBs have made their mark in movies, songs, even well know phrases. Funny the first thing that comes to mind when I hear of a CD Radio is the movie " Smokey and the Bandit" and the phrase "10-4 good buddy".
