These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Wireless networks use radio waves or other wireless methods to connect devices without cables.
- Wireless networks provide flexibility and mobility, but may have limitations, like interference and security risks.
Keywords
Wireless local area network - a network that connects devices wirelessly using radio waves within a limited area
Wi-Fi - network protocols that allow devices to communicate over a local network using radio waves
Bluetooth - a standard for wireless technology that is used for exchanging data over short distances
Common misconception
Wireless networks are always better than wired ones because they don’t use cables.
Wireless is more convenient, but it can be slower, less secure and more prone to interference. Wired connections are often better for speed, stability and data heavy tasks.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
