Sample Answer

 

 

 

Wireless Local Area Networks (WLANs) operate in two primary modes: Infrastructure and Ad-Hoc. Each mode has its own characteristics, advantages, and limitations.

Infrastructure Mode

In Infrastructure mode, devices communicate with each other through a central access point (AP). The AP acts as a bridge between devices, relaying data packets and managing network traffic.

Components:

  • Wireless Access Point (AP): A device that provides wireless connectivity to other devices.
  • Wireless Network Interface Cards (WNICs): Devices like laptops, smartphones, and tablets equipped with WNICs can connect to the AP.

Drawbacks and Limitations:

  • Single Point of Failure: If the AP fails, the entire network becomes inaccessible.
  • Configuration Complexity: Requires careful configuration of the AP and network settings.
  • Limited Range: The range of the network is limited by the AP’s coverage area.

Ad-Hoc Mode

In Ad-Hoc mode, devices communicate directly with each other without the need for a central access point. This mode is often referred to as peer-to-peer networking.

Components:

  • Wireless Network Interface Cards (WNICs): Devices must have WNICs to establish direct connections.

Drawbacks and Limitations:

  • Limited Range: The range of the network is limited by the wireless capabilities of the devices.
  • Lower Throughput: Compared to Infrastructure mode, Ad-Hoc mode typically offers lower data transfer rates.
  • Network Management Challenges: Ad-Hoc networks can be more difficult to manage and configure.

In Summary:

While Infrastructure mode offers better performance, security, and scalability, Ad-Hoc mode is simpler to set up and can be useful for temporary or small-scale networks. The choice of mode depends on the specific requirements of the network, such as the number of devices, the desired range, and the level of security required.
