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. |
