Describe the structures needed for landline and cell phone systems and compare their advantages and disadvantages.

Here's the breakdown for Activity 4.6:

1. Structures required for each phone system:

• Landline phone system:

  • Landline telephone set
  • Telephone cables (e.g., copper wires, fiber optic cables, undersea cables)
  • Telephone exchanges (central offices)
  • Telephone poles (for overhead cables) or underground conduits

• Cell phone system:

  • Cell phone (mobile device)
  • Cell towers (base stations/relay towers)
  • Network infrastructure (linking towers, switching centers)
  • Satellites (for broader coverage, as shown in the diagram)
