Vodafone UK's high-speed network is state-of-the-art, the result of billions in investment over the last five years. But how do all the parts fit together?
The coronavirus crisis is bringing home to people just how important our mobile and fixed line broadband networks are in keeping the UK connected.
Our introductory guide explains how they all work.
The Radio network
Let’s start with the most visible part of the network – masts and antennas. Whether 2G, 3G, 4G or 5G, they use radio waves to transmit voice calls, texts and internet data to and from our smartphones and other devices.
The broadcast area of each mast has to overlap a little with the next one along. This helps ensure that, even when you move out of range of one mast and into the range of another, your calls don’t drop and your mobile data continues to send and receive uninterrupted.
Masts and antennas come in all shapes and sizes, not just the lattice towers that are the most visible. To find out more about masts – why they have to be where they are and so on – read our Q&A.
