2. INTRODUCTION The increasing demands of the voice & data end users are driving the development of new networking techniques that accommodate mobile voice & data users who move throughout buildings,cities or countries.

3. wireless networking The term wireless networking refers to technology that enables two or more terminals to communicate using standard network protocols, but without network cabling. Strictly speaking, any technology that does this could be called wireless networking .

7. Kinds of wireless networks 1.Adhoc or peer-to-peer network. 2.Wireless networking with access point.

8. An Ad-Hoc, or Peer to Peer wireless network consists of a number of computers each equipped with a wireless networking interface card. Each computer can communicate directly with all of the other wireless enabled computers.

9. Each computer with a wireless interface can communicate directly with all of the others. Ad-Hoc or Peer-to Peer Networking.

10. Infrastructure wireless network A wireless network can also use an access point, or base station. In this type of network the access point acts like a hub, providing connectivity for the wireless computers.

11. Types of access points Hardware access points. Software access points.

12. Hardware Access Point

13. Software Access Point

14. Wireless Networking Components Stations: A station (STA) is a network node that is equipped with a wireless network device. Access points: A wireless AP is a wireless network node that acts as a bridge between STA and a wired network. Ports: A port is a channel of a device that can support a single point-to-point connection.

18. A wireless computer can "roam" from one access point to another, with the software and hardware maintaining a steady network connection by monitoring the signal strength from in-range access points and locking on to the one with the best quality. Roaming A user can move from Area 1 to Area 2 transparently. The Wireless networking hardware automatically swaps to the Access Point with the best signal.
