1.3 Applications
The 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
wireless LANs:
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.
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.
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.
Frequently changed environments
Show rooms, meeting rooms, retail stores, and manufacturing sites where frequently rearrange
the workplace.
Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy and quick installation of a small network.
-2-
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 networks.
Training/Educational facilities
Training sites at corporations and students at universities use wireless connectivity to ease
access to information, information exchanges, and learning.
1.4 Network Configurations
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.
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.
-3-
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.

Maximum associated stations: this limits the number of stations that can associate with
the Access Point.
Fragmentation threshold: this value indicates how much of the Access Point’s
resources are devoted to recovering packet errors. The value should remain at its default
setting. If you decrease this value too much you may encounter high packet error rates,
however if you increase it too much it will affect overall performance. Therefore, it is
recommended to leave this value at its default of 2346.
RTS threshold: transmitted wireless packets larger than this size will use the RTS/CTS
protocol to (a) maintain performance in noisy wireless networks and (b) prevent hidden
nodes from degrading performance.
Beacon period: this value indicates the frequency interval of the beacon. The beacon
is a packet broadcasted by the Access Point to keep the network synchronized. A beacon
consists of the wireless LAN service area, IP address, broadcast destination address, time
stamp, Delivery Traffic Indication Map (DTIM) and Traffic Indicator Message (TIM).
DTIM Interval: this value indicates the interval of the Deliver Traffic Indicator Map
(DTIM). The DTIM field is a countdown field informing clients of the next window
for listening to broadcast and multicast messages. When the Access Point has buffered
broadcast of multicast messages for associated clients, it sends the next DTIM with a
DTIM interval value. Clients hear the beacons and then awaken to receive the broadcast
or multicast messages.
