  4. TELECOMMUNICATION NETWORKS • 1) Home to a Home using landline phones: • Same Area Code • Different Area Code

  5. TELECOMMUNICATION NETWORKS • 2) Cell Phone to Cell Phone • Same Cell Tower Area • Different Cell Tower Area

  6. TELECOMMUNICATION NETWORKS • 3) Landline to a Cell Phone

  7. TELECOMMUNICATION NETWORKS • 4) Cell Phone to Satellite Phone

  8. Telecommunications • What is Telecommunications? Give some examples for both pre and post electricity: • How do landline phones work? • How do cell phones work? What type of waves do they use? • What are the different components of the cell phone system? • How does a satellite phone work? • How do you think features like text messages, GPS, and internet work on cell phones?
