Adhoc Adhoc A peer-to-peer (P2P) network allows wireless devices to directly communicate with each other. Wireless devices within range of each other can discover and communicate directly without involving central access points. This method is typically used by two computers so that they can connect to each other to form a network.

AP Based TechnologyAP Based Technology

The more common type of topology that allows access to wired network resources is the infrastructure topology. In this topology, APs are added to a switch, which provides connectivity to wireless stations

Point to multipointPoint to multipoint

This is used to connect a LAN in one building to a LANs in other buildings even if the buildings are miles apart

Why Wi-Fi?

Setup Cost – Reduced cabling required

Flexibility – Quick and easy to setup intemp or permanent space

Scalable – Can be expanded with growth

Freedom – You can work from any locationthat you can get a signal

Lower total cost of ownership – Because ofaffordability and low install cost

GPSGPSThe GPS consists of three parts: the space segment, the control segment, and the user segment. GPS satellites broadcast signals from space, which each GPS receiver uses to calculate its three-dimensional location(latitude, longitude, and altitude) plus the current time.
