A wireless LAN or WLAN is a wireless local area network‚ which is the linking of two or more computers or devices without using wires. WLAN uses spread-spectrum or OFDM modulation technology based on radio waves to enable communication between devices in a limited area‚ also known as the basic service set. This gives users the mobility to move around within a broad coverage area and still be connected to the network. For the home user‚ wireless has become popular due to ease of installation‚ and

The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The

connections are called LANs. LAN (local area network) is a group of computers and other electronic devices that are connected via a communications line. The LAN’s I will talk about are wired and wireless LANS. Before wireless networking‚ everything was connected with wires. However‚ today data can be transported wirelessly as well. In this paper‚ I will talk about how I would go about practicing my LAN design. Wired networks can be very costly. Wired networks are probably the fastest way of moving

Wireless cards. Wireless cards are very different based upon what chipset you have. I personally use Atheros chipset cards which has screwed me up a bit with BackTrack as it has problems with using them for certain attacks. What I will again show is generic commands for setting up and configuring your wireless interfaces. The interface name (ath0 below) is entirely dependant on what chipset you are using‚ you may have any of the following: ath0 wlan0 wifi0 eth0 You need to find

Telecomm For Business Dear Friend‚ I heard that you were installing a wireless LAN in your small business‚ but you were concerned about security. Well when it comes to installing a wireless LAN‚ there are several security threats that you should be aware of beforehand. There are four common security threats‚ which are drive-by hackers‚ war drivers‚ unprotected access points‚ and rogue access points. Drive-by hackers‚ which are the most serious threats of them all‚ are people that sit outside
