Artwork: Communications satellite. From US Patent: #3,559,919: Active communication satellite, courtesy of US Patent and Trademark Office. These are amazingly complex and expensive machines with tons of electronic bits and pieces jammed into them, but let's not get too bogged down in the detail...
Communication and navigation satellites would be impossible without radio waves, as would modern aviation — an airplane depends on a dozen different radio systems. The WiFi networks that we depend on at work, home and school also rely completely on radio waves for data transmission. The funny ...
Communication satellites are similar to space mirrors that let us bounce communications such as internet data, television, and radio from one side of the world to the other. It consists of three steps that might assist in explaining how it works: Uplink Transponders, and Downlink Consider the ...
While a loss of communication can be a problem in many instances, it's a bigger issue in an emergency situation. Being able to contact loved ones and friends to make sure they are OK is an essential role of mobile phone networks. However, with power cuts able to take down cell towers ...
If you go back to the days of the manual switchboard, it is easy to understand how the larger phone system works. In the days of the manual switchboard, there was a pair of copper wires running from every house to a central office in the middle of town. The switchboard operator sat in...
