Supporting a dense user base confined to a small coverage area. Because 802.11a 
has a greater number of non-overlapping channels, you can pack more access 
points in a tighter space.

The wireless solution supports a stand-alone wireless network configuration as well as 
an integrated configuration with 10/100 Mbps Ethernet LANs.

The wireless network cards, adapters, and access point can be configured as:

n

Ad hoc for departmental or SOHO LAN

n

Infrastructure for wireless LAN

n

Infrastructure wireless LAN for roaming wireless PCs

An ad hoc wireless LAN consists of a group of computers, each equipped with a 
wireless adapter, connected via radio signals as an independent wireless LAN. 
Computers in a specific ad hoc wireless LAN must therefore be configured to the same 
radio channel. An ad hoc wireless LAN can be used for a branch office or SOHO 
operation.

The access point can also provide access to a wired LAN for wireless workstations. An 
integrated wired/wireless LAN is called an infrastructure configuration. A Basic 
Service Set (BSS) consists of a group of wireless PC users, and an access point that is 
directly connected to the wired LAN. Each wireless PC in this BSS can talk to any 
computer in its wireless group via a radio link, or access other computers or network 
resources in the wired LAN infrastructure via the access point.
