Cellular Networks
Foreword
Section titled “Foreword”This documentation started as an excuse to finally understand why phones magically work when you shout into them on a bus, and it quickly grew into “let’s try to demystify as much networking stuff as possible.” It will wander beyond cellular networks, but 1G (and friends 2G, 3G, 4G, 5G) will get extra love, with some parts going much deeper than any sane “for dummies” book probably would.
Everything here is written as a personal learning project, so expect a mix of big-picture explanations, oversimplifications, and occasional rabbit holes where a small detail gets an entire page. This is not official, peer‑reviewed, standards‑body‑approved documentation, and it will almost certainly contain errors, bad jokes, and outdated facts. Read at your own risk: the author takes no responsibility for any misunderstandings, misconfigurations, or confused looks you might get while trying to explain this to your friends.
