We talk a lot about environmentally friendly mobile phone technology, but we don’t explain how it all works, but now is the time to get into it.

We go through the technology from sound, what’s going on inside your phone, how it sends the signal out, to towers and how they work. The cell network is probably the most important part of the mobile phone network in terms of its environmental impact. Then, you’ll learn how phones receive signals, how that signal is translated into sound again.

At every stage, we look at its environmental impact and how we can improve mobile phone technology so it’s a more environmentally friendly part of our lives.

As a warm-up, the BBC have a few interesting pages about mobile technology. Although they’re aimed at teenagers studying for their GCSE examinations, they’re a great way to get a simple introduction to the subject.

Start off with their page about technology through time. It explores mobile devices up to the smartphone.

Next on your list should be their overview of mobile communication technology. They perform a 4G vs 5G comparison, describing them as mobile broadband. 5G does indeed promise speeds much faster than those available with the fastest home broadband in the UK, though other countries have had faster speeds both at home and on the phone for years.

Check them out and boost your knowledge of mobile phones and how they work with the network.
