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:
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.

1.4 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.
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-topeer, 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.
Page 7 of 7
Wireless Multi-Client Bridge / Access Point / Repeater
Version 1.2
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.

On this page you can manage 802.11b/g of the Access Point. The image
below depicts the configuration screen of the General option.
Visibility Status: select Visible or Invisible. This option displays or hides
the SSID of this Access Point from other Access Points.
Wireless Connection Mode: select an Access Point mode from the drop
down list. Options available are 802.11g Only, 802.11g Only (Maximum
Performance), 802.11b/g Mixed Mode Long, and 802.11b Only,
Wireless Network Name (SSID): the SSID is a unique name shared among
all points in your wireless network. The SSID must be identical for all points in
the network. It is case sensitive and must not exceed 32 characters.

Version 1.2
6.5.2 Advanced
Click on the Advanced link on the navigation bar. On this page you may
configure the maximum associated stations, thresholds, beacon periods,
DTIM interval, maximum burst time, PSM mode. The image below depicts the
configuration screen of the Advanced option.
Fragmentation threshold: transmitted wireless packets larger than this size
will be fragmented to maintain performance in noisy wireless networks.
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: Access Point beacons are sent out periodically. This is the
number of milliseconds between each beacon.
DTIM interval: this is the number of beacons per DTIM (Delivery Traffic
Indication Message), e.g. '1' means send a DTIM with each beacon, '2'
means with every 2nd beacon, etc.
Maximum burst time: this is also known as PRISM Nitro (tm) technology.
The technology uses fully standards-compliant methods that eliminate
collisions in mixed-mode networks, while greatly increasing the performance
of both pure 802.11g and mixed 802.11b/g networks. The setting is for the
amount of time the radio will be reserved to send data without requiring an
ACK. This number is in units of microseconds. A typical value would be 1000
microseconds. When this number is zero, bursting is disabled.
PSM Mode: turn this on to enable support for stations in power save mode.
