Wireless LAN topologies
We can configure wireless LAN in many different topologies, depending on how we want to use the LAN. In wireless LAN, each computer broadcasts in the air rather across the wires. Here are described few examples of wireless topologies:
Adhoc (Wireless Peer to Peer): The data, in this topology, is broadcasted to all the nodes in proximity. But is accepted only by that system for which it is intended for. This is useful only if we are sharing files and printers within a group of client systems.
Infrastructure (Wireless Access Point): In this topology the client computers can be configured to communicate directly with access point. No system communicates directly with its peer. His type of topology is useful for point to point connections between different buildings where access point acting as gateway to internet.
Multiple wireless access points and roaming: Every wireless network can be configured as separate cell. Then multiple cells can be joined as Managed Wireless LAN. The Access Point of each cell functions as a bridge. In this course of action it passes all the data of one cell to another without changing any node’s MAC address. This allows users to roam around cells without losing continuity of communication.
