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.

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.
