Wireless LAN products are easy to install and
highly efficient. The following list describes some of the many
applications made possible through the power and flexibility of a
1. Work from Home
Computers and high-speed Internet access mean new,
better-paying choices for people who want the flexibility and
convenience of careers that don't require an office-building

2. Difficult-to-wire environments
There are many situations where wires cannot or
cannot easily be laid. Historic buildings, older buildings, open
areas and across busy streets make the installation of LANs either
impossible or very expensive.
3. Temporary workgroups
Consider situations in parks, athletic arenas,
exhibitions, disaster-recovery, temporary office and construction
sites where one wants a temporary WLAN established and removed.
4. 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.
5. Frequently changed environments
The show rooms, meeting rooms, retail stores, and
manufacturing sites are where the workplace is frequently
6. Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy and quick
installation of a small network.
7. 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.
Wired LAN backup
Network managers implement wireless LANs to
provide backup for mission-critical applications running on wired
9. Training/Educational Facilities
Training sites at corporations and
students at universities use wireless connectivity to ease access
to information, information exchanges, and learning.

1. Infrastructure for enterprise LANs.
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
whether the AP is wired to an Ethernet network or stands
alone. If used as a stand-alone, the AP can extend the range
of independent wireless LANs by acting a repeater, which
effectively doubles the distance between wireless stations
If wired to an Ethernet network, the AP
serves as a bridge and provides the link between the server
and the wireless clients. The wireless clients can move
freely throughout the coverage area of the AP while
remaining connected to the server. Since the AP is connected
to the wired network, each client would have access to
server resources as well as to other clients.
2. Ad-hoc (peer-to-peer)
This is the simplest network
configuration that 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 linked
peer-to-peer and would only have access to the resources of
the other client, this requires no access point. This is the
easiest and least expensive way for the SOHO to set up a
