We always see this network mast everywhere but have you ever wonder what work they do for us? Your mobile phone's network is working away in the background every time you update your Facebook status, make a call or send a text. Our network delivers billions of voice calls, messages and megabytes of data every year, and we understand that all of that communication is important to you.  So we take network matters seriously . How do I get coverage? Mobile phone networks are made up of thousands of masts, which are located all over the UK. At the top of each mast, there's an antenna. This is the part that sends and receives signals. Each antenna creates an area of coverage between 100 metres and 10 kilometres. The most powerful antennas are called macrocells, and they're located on tall masts on top of buildings or in fields. They create a large area of coverage. Busy areas are boosted with smaller microcells, which are located inside things like road signs, flag...
