Questions and Answers

What is the primary function of cellular networks regarding mobile devices?

  • To reduce the bandwidth requirements of cellular devices
  • To enable mobile communication for devices like smartphones and tablets. (correct)
  • To provide Wi-Fi access to smartphones and tablets.
  • To limit internet access to specific devices.

    • Why are the coverage areas of base stations approximated as hexagonal?

  • Because environmental factors, like terrain and buildings, affect radio signal propagation. (correct)
  • Because square shapes don't provide enough coverage.
  • Because base stations themselves are exactly hexagonal.
  • Because it offers the most visually appealing coverage.

    • What distinguishes smartphones from basic cell phones?

  • Smartphones are larger in size and typically more expensive
  • Smartphones only allow voice calls, not SMS or internet access.
  • Smartphones only use Wi-Fi for internet access

    Study Notes

    Cellular Networks and Mobile Communication

    • Cellular networks enable mobile communication for devices like smartphones and tablets.
    • Many laptops and some tablets rely on Wi-Fi instead of cellular networks.
    • Smartphones often utilize both cellular and Wi-Fi networks.

    Cellular Network Structure

    • Cellular networks divide geographic areas into roughly hexagonal cells, centered around base stations.
    • The hexagonal shape is an approximation due to obstacles affecting radio signals (e.g., buildings, trees).
    • Square shapes are also used sometimes.
    • The area covered by a base station is called a cell.
    • This is why these devices are referred to as cell phones in some regions or mobile phones in others.
    • Cell phones can handle voice calls and text messages (SMS).

    Smartphone Capabilities

    • Smartphones are cell phones with additional features, like Wi-Fi and cellular access for internet use (e.g., email, web browsing).
    • They support various applications including apps, social media, and other services.
    • Cellular networks allow seamless movement between base stations, which enables mobile use of apps and services.
    • Cellular networks connect to public communication networks for internet access.
    • Sufficient bandwidth is present for these operations.
