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
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
frequently rearrange the workplace.
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 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:
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.
