In this activity, students use a model of a satellite dish to investigate how a curved reflector can be used to increase Wi-Fi signal strength as received by a cell phone.

By the end of this activity, students should be able to:

  • describe how a concave satellite dish receives signals from a satellite
  • use a model of a satellite dish using an umbrella and aluminium foil as a curved reflector to increase the strength of a Wi-Fi signal and to locate the position of maximum signal strength.
