Wireless network:

  • In computer network, the wireless network uses wireless data connections for connecting network nodes.
  • It is a process by which telecommunications network, business installations and homes avoid the costly process of introducing cables to provide connection between many equipment locations.
  • Example of wireless network include Wireless Local Area Networks (WLANs), cell phone networks, satellite communication networks and wireless sensor network.

Explanation of Solution

Operation of wireless network in infrastructure mode:

  • Infrastructure mode is a networking framework of 802.11 that uses access point to communicate with each other.
  • With the use of infrastructure mode the wireless devices can communicate with each other.
  • The operation of infrastructure mode where each wireless hosts are connected to the large network through base network which is termed as access point.

Mode of operation:

  • If the network is not in the infrastructure mode, it is consider as an ad-hoc mode of operation.
  • The ad-hoc mode communicates each other without the help of access point.

Difference between mode of operation and infrastructure mode:

Mode of operation

Infrastructure mode

This device is used to communicate each other directly.

The wireless devices can communicate with each other in the infrastructure mode.

The access point is not used here to communicate with each other.

Infrastructure mode need access point to communicate with each other.

Ad-hoc mode communicate only with other ad-hoc devices.

The access point controls wireless communication and offer many important benefits over an ad-hoc network.

Security is less in ad-hoc mode when compare with infrastructure mode.

It support high level security, possibly faster data transmission speeds.
