Understanding Wireless and Mobile Networks helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Wireless and Mobile Networks in detail
Wireless networks send data using radio waves instead of cables. Wi-Fi connects devices to a local network through a wireless access point, using standards such as 802.11, and Bluetooth links devices over short distances. Mobile (cellular) networks use base stations in cells, with generations 3G, 4G and 5G offering faster speeds and lower delay.
Wireless is convenient and flexible, but it is generally slower and less reliable than wired connections, can suffer interference and is easier to intercept, so encryption (WPA3) and strong passwords are essential. Signal range and number of users affect performance. Mobile networks enable the Internet of Things and smartphones.
How the interactive helps you understand Wireless and Mobile Networks
Watch the network in the interactive. Use any sliders or buttons it offers to change the values and see how the network responds.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Wireless and Mobile Networks.
Real-life uses and examples
- Recognise Wireless and Mobile Networks in an app or device you use every day.
- Apply Wireless and Mobile Networks when you design a small program, website or spreadsheet.
- Explain Wireless and Mobile Networks to someone new to computing by comparing it to a familiar process.
Common mistakes to avoid
- Using the term without being able to say what the computer actually does.
- Testing only the normal case and forgetting the edge cases.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
