108Mbps 802.11g High Power Wireless USB 2.0 Adapter 5 1.5 Applications . 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 easily installed. 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) Dynamic environments Show rooms, meeting rooms, retail stores, and manufacturing sites where the workplace is frequently rearranged. e) Small Office and Home Office (SOHO) networks SOHO users need a cost-effective, easy–to-install 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.
108Mbps 802.11g High Power Wireless USB 2.0 Adapter 6 1.6 Network Configuration To better understand how wireless devices work together to create a wireless network, it might be helpful to depict a few of the possible wireless network configurations. Wireless devices can be configured as: a) Ad hoc (or peer-to-peer) b) Infrastructure a) Ad hoc (peer-to-peer) Mode In ad hoc mode, each client is peer-to-peer. The client would only have access to the resources of the other client. Ad hoc mode 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 above depicts a network in Ad hoc mode.
108Mbps 802.11g High Power Wireless USB 2.0 Adapter 7 b) Infrastructure Mode Infrastructure mode requires the use of an access point (AP). In this mode, all wireless communication between clients passes through an 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. The image below depicts a network in infrastructure mode.
