The following list describes some of the many applications made possible through the power and flexibility of wireless LANs: a) Difficult-to-wire environments There are many situations where wires cannot be laid easily. Historic buildings, older buildings, open areas and across busy streets make the installation of LANs either impossible or very expensive. b) Temporary workgroups Consider situations in parks, athletic arenas, exhibition centers, disaster-recovery, temporary offices and construction sites where one wants a temporary WLAN established and removed. c) The ability to access real-time information Doctors/nurses, point-of-sale employees, and warehouse workers can access real-time information while dealing with patients, serving customers and processing information. d) Frequently changed environments Show rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange the workplace. e) Small Office and Home Office (SOHO) networks SOHO users need a cost-effective, easy and quick installation of a small network. f) Wireless extensions to Ethernet networks Network managers in dynamic environments can minimize the overhead caused by moves, extensions to networks, and other changes with wireless LANs. g) Wired LAN backup Network managers implement wireless LANs to provide backup for mission-critical applications running on wired networks. h) Training/Educational facilities Training sites at corporations and students at universities use wireless connectivity to ease access to information, information exchanges, and learning. Network Configuration To better understand how the wireless LAN products work together to create a wireless network, it might be helpful to depict a few of the possible wireless LAN PC card network configurations. The wireless LAN products can be configured as: a) Ad-hoc (or peer-to-peer) for departmental or SOHO LANs. b) Infrastructure for enterprise LANs.
EUB9801 –300Mbps 802.11 a/b/g/n Dual Band Wireless N USB Adapter Version 1.0 6 a) Ad-hoc (peer-to-peer) Mode This is the simplest network configuration with several computers equipped with the PC Cards that form a wireless network whenever they are within range of one another. In ad-hoc mode, each client is peer-to-peer, would only have access to the resources of the other client and does not require an access point. This is the easiest and least expensive way for the SOHO to set up a wireless network. The image below depicts a network in ad-hoc mode. b) Infrastructure Mode The infrastructure mode requires the use of an Access Point (AP). In this mode, all wireless communication between two computers has to be via the AP. It doesn’t matter if the AP is stand-alone or wired to an Ethernet network. If used in stand-alone, the AP can extend the range of independent wireless LANs by acting as a repeater, which effectively doubles the distance between wireless stations. The image below depicts a network in infrastructure mode.
EUB9801 –300Mbps 802.11 a/b/g/n Dual Band Wireless N USB Adapter Version 1.0 7 2 USB Adapter for Windows (XP & Vista) Before You Begin During the installation, XP may need to copy systems files from its installation CD. Therefore, you may need a copy of the Windows installation CD at hand before installing the drivers. On many systems, instead of a CD, the necessary installation files are archived on the hard disk in C:\WINDOWS \OPTIONS\CABS directory. WiFi Alliance certification recommends WPA2 AES to be the security mechanism under 11N mode. System driver will automatically bring down wireless data rate to 54Mbps if other security method such as WEP or WPA is used under 11n mode. If your 11N router is using security mechanism other than WPA2 AES, you are recommended to disable security setting or change it to WPA2 AES to fully utilize 11N capability. This policy has no effect if connecting with b/g only wireless access point.
