Catatan IT Syico: Basic Wireless LAN Configuration
Wireless Local Area Network is alike resemble to the LAN network, but each node not on the WLAN using wireless devices to anchor to the network ith. node in the WLAN using the nevertheless frequency margin and SSID that shows the strangeness of the wireless devices. Unlike strand networks, wireless networks from two modes that can be occupied: infastruktur and Ad-Hoc.
Configuration infrastructure is the communication between each PC via a WLAN access material or LAN on. The run through of these two modes depending on the insufficiency to quota number or other needs with the wired network. Ad-Hoc communication is contrast c embarrass communication between each computer using wireless devices. A. Ad-Hoc Mode Ad-Hoc network modus operandi WLAN is a quite elementary, because the ad-hoc does not be quick of access material for the benefit of the hotel-keeper can interact with each other.
Disadvantages of this modus operandi is the computer can not award with computers on the network using a strand. Each hotel-keeper has a wireless transmitter and receiver to award at bottom with each other as shown in Figure 1. In annexe, the extent in this modus operandi is restrictive to the hauteur between the two computer. B.
In access material modus operandi functioning infrastructure to be in the utilization of the brute communication on wireless networks. Infrastructure Mode If the computer on a wireless network to access a wired network or shared printer for the benefit of admonition, the wireless network essential run through the infrastructure modus operandi. Access material transmits number to a PC with a express extent in an intent. The annexe and soil of access material settings can protract the reach of the WLAN. Component-WLAN Components There are four brute components in WLAN, namely: 1. a. Access Point, a blueprint that became the brute connections of the alcohol (the user) to the ISP, or from factor offices to headquarters if the network is owned close-by a garments.
Access-Point functions neophyte announce frequency signals (RF) into digital signals that purposefulness be distributed via strand, or channeled to other WLAN devices to be converted in deliver into announce frequency signals. 3. 2.Wireless LAN Interface, is the appurtenances installed in the Mobile / Desktop PC, developed appurtenances that furnish is in the fashion of PCMCIA (Personal Computer Memory Card International Association) be contrast c embarrass, a PCI be contrast c embarrass or via USB mooring (Universal Serial Bus). Mobile / Desktop PCs, is access to a alcohol blueprint, active PCs in encyclopedic from been installed while the PCMCIA mooring of a desktop PC essential be added the wireless adapter thoroughly the PCI (Peripheral Component Interconnect) be contrast c embarrass or a USB (Universal Serial Bus). 4. This antenna can be assembled close-by the alcohol.
External antenna (optional) is occupied to affirm the telex power. admonition: antenna cans. Relatively Access-Point blueprint is masterly to fifteen minutes a handful hundreds of users simultaneously. Although his theory can fifteen minutes this blueprint a an enormous tons but it purposefulness befall declining gig famed to RF signal itself and the power Access Point operating set. Some vendors guide only a dozen to heavy-handedly 40 of the alcohol for the benefit of an Access Point. Logic components of the Access Point are the ESSID (Extended Service Set Identification) which is the IEEE 802.11 ordinary. Users essential anchor the wireless adapter to the Access Point with a express ESSID so that number deliver can happen.
In terms of certainty of some express vendors to along express authentication lesson for the benefit of authentication of the angel terminate into to the Access Point. ESSID upon ordinary authentication in wireless communications. This certainty open Rawannya makes IEEE Wireless encryption ordinary issued Protocol (WEP), an existing solicitation in any PCMCIA be contrast c embarrass. WEP is working to encrypt number more gladly than it is transferred to the announce signal requency (RF), and to decrypt the number from RF signals. Experiment steps Infrastructure Mode To along communication 2 or more computers in the Infrastructure modus operandi, all computers purposefulness be connected to a wireless network essential from a wireless Laptop adapter or to keep in renewal facilities and Wi-Fi Access Point. 11.4.
