1- 5 Applications
The SL-2011 PLUS 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:
1. Difficult-to-wire environments
There are many situations where wires can not or can not easily be laid.
Historic buildings, older buildings, open areas and across busy streets make
the installation of LANs either impossible or very expensive.
2. 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.
3. The ability to access real-time information
2

Doctors/nurses, point-of-sale employees, and warehouse workers can
access real-time information while dealing with patients, serving customers
and processing information.
4. Frequently changed environments
Show rooms, meeting rooms, retail stores, and manufacturing sites where
the workplace is frequently rearranged.
5. Small Office and Home Office (SOHO) networks
SOHO users need a cost-effective, easy and quick installation of a small
network.
6. 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.
7. Wired LAN backup
Network managers implement wireless LANs to provide backup for
mission-critical applications running on wired networks.
8. Training/Educational Facilities
Training sites at corporations and students at universities use wireless
connectivity to ease access to information, information exchanges, and
learning.
1- 6 Network Configurations
To better understand how the SL-2011 PLUS wireless LAN products
work together to create a wireless network, it might be helpful to depict a
few of the possible SL-2011 PLUS network configurations. The SL-2011
PLUS wireless LAN products can be configured as:
1. Ad-hoc (or peer-to-peer) for departmental or SOHO LANs.
2. Infrastructure for enterprise LANs.
3. IP Sharing for 56K/ISDN TA/Cable/DSL Modem – Connect Internet and your
SOHO network.
Ad-hoc (peer-to-peer) Mode
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 (Figure 1-3). In ad-hoc mode, each
client, is peer-to-peer, would only have access to the resources of the
other client and requires no the access point. This is the easiest and
least expensive way for the SOHO to set up a wireless network.

Figure 1-3 A wireless Ad-hoc network
Infrastructure Mode
The infrastructure mode requires the use of an access point (AP). In this
mode, all wireless communications between two computers have to be
via the AP no matter the AP is wired to Ethernet network or stand-alone.
If used in stand-alone, the AP can extend the range of independent
wireless LANs by acting a repeater, which effectively doubling the
distance between wireless stations as shown in Figure 1-4.

Infrastructure

If wired to an Ethernet network as shown in Figure 1-5, 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.
Figure 1-5 Single AP bridge
Access points have a finite range, on the order of 50 meters indoor and
100 meters outdoors. In a very large facility such as an enterprise, a
warehouse, or on a college campus, it will probably be necessary to
install more than one access point to cover an entire building or campus,
as shown in Figure 1-6. In this scenario, access points hand the client
off from one to another in a way that is invisible to the client, ensuring
unbroken connectivity. Wireless clients can roam seamlessly between
different coverage areas and remain connected to the network

Wireless Router and IP Sharing
In infrastructure mode, in addition to acting as a bridge between an
Ethernet and wireless network, the AP can be configured as a wireless
router and IP sharing device for Internet access as shown in Figure 1-7.
You don’t have to buy an expensive router. Nor you have to buy several
modems and setup phone lines. Just share one AP, one Modem, single
dial-up account, and one phone line, dozens of network users can go
surfing the Internet concurrently.

# 802.11 AdHoc: this is the IEEE802.11 peer-to-peer mode of operation and
requires no Access Point. When wireless clients are operating in this
mode, all wireless clients require the same SSID and the channel number
is not important.
# AdHoc: this is non-standard peer-to-peer mode of operation and requires
no Access Point. When wireless clients are operating in this mode, all
wireless clients require the same channel number ,and the SSID is not
13

important
# Infrastructure: this mode of operation requires the use of an Access Point.
In this mode, all wireless communications between computers have to be
via the Access Point. (Default setting is Infrastructure)
SSID
SSID is an identification code required for communication in a wireless LAN.
You will only be able to connect with a wireless client (802.11 AdHoc) or an
Access Point (Infrastructure) which has the same SSID. If the SSID of a PC
Card is set as any, then the PC Card can connect to all availableAccess
Points. (Default setting is IEEE802.11)
Tx Rate
Select the transmission rate at which the data packets are transmitted by the
client. You can set this to Fully Automatic, 1Mbps, 2Mbps, Auto 1 or 2Mbps,
