Lesson 3 Wired and wireless networks

Curriculum > KS3 > Unit > Lesson

This lesson explores the different wireless technologies, and how bandwidth varies between these technologies. Learners will discuss the mobile technologies of 3G, 4G, and 5G. Learners will develop an understanding of the term ‘bandwidth’ and test the performance of their own internet connection. Learners will also develop an appreciation for online activities that are bandwidth-heavy, before moving on to explore the advantages and disadvantages of wired and wireless networks. By the end of the lesson, learners should be able to identify whether a wired or wireless network should be used in a number of given scenarios.

Learning objectives

  • Compare wired to wireless connections and list examples of specific technologies currently used to implement such connections
  • Define ‘bandwidth’, using the appropriate units for measuring the rate at which data is transmitted, and discuss familiar examples where bandwidth is important
