Let’s explore the technology behind mobile communications.Watch the video from “Learn Engineering” to learn more on “How does your mobile phone work?”
Mobile phones communicate with cell towers that are placed to give coverage across a telephone service area which is divided up into ‘cells’. Each cell uses a different set of frequencies from neighbouring cells, and will typically be covered by 3 towers placed at different locations.
The cell towers are usually interconnected to each other and the phone network and the internet by wired connections. Due to bandwidth limitations each cell will have a maximum number of cell phones it can handle at once.//wikipedia
