DEFINITION OF NETWORK MODEL WIRELESS LAN :: AD-HOC MODE AND INFRASTRUCTURE

Introduction Model Wireless Network

Network models Wireless Local Area Network consists of two models jenis.yaitu ad-hoc and infrastructure models. Actually, almost the same wireless LAN network to a LAN network cables, but each node in the WLAN uses a wireless device to be associated with the network, the nodes in the WLAN using the same frequency channel and SSID which indicates the identity of the wireless device. What distinguishes LAN cable networks, wireless networks have two models that can be used: Infrastructure and Ad-Hoc. Infrastructure configuration is the communication between each PC via a WLAN access point or LAN. Ad-Hoc communication is direct communication between each computer by using the tool wireless.Penggunaan both modes depending on the need to share data or other needs with a wired network.

mode wireless LAN ad hoc network
Ad-Hoc wireless LAN is a network model is very simple, because the ad-hoc does not require access pointuntuk host can interact. On each host quite memilikitransmitter and wireless receiver that can communicate directly with each other. Disadvantages of this model is is the limited range, the computer can not communicate with computers on the network using a network cable. In addition, the coverage area of this model is limited to the distance between the second computer.

Infrastructure mode
If the computer on the wireless network wants to access a wired network or shared printer, for example, then it should use the model jaringanwireless infrastructure In the model access point infrastructure to serve the primary communication function on jaringanwireless. The access point transmits data on a PC with a certain range in an area. Additions and layout settings access point can extend the range of Wireless LAN in Wireless infrastructure network model this.
