The higher spectrum provides about 50 meters (164 feet) of coverage-about half what 802.11b offers. Consider 802.11a when you need high throughput in a confined space and you are: I Running high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a fivefold increase in data throughput I Transferring large files like computer aided design files, preprint publishing documents or graphics files, such as MRI scans for medical applications, that demand additional bandwidth I 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. NETWORK CONFIGURATION AND PLANNING 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: I Ad hoc for departmental or SOHO LAN I Infrastructure for wireless LAN I Infrastructure wireless LAN for roaming wireless PCs AD HOC WIRELESS LAN 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. 9

The higher spectrum provides about 50 meters (164 feet) of coverage—about
half what 802.11b offers.
Consider 802.11a when you need high throughput in a confined space and
you are:
■
Running high-bandwidth applications like voice, video, or multimedia over a
wireless network that can benefit from a fivefold increase in data throughput
■
Transferring large files like computer aided design files, preprint publishing
documents or graphics files, such as MRI scans for medical applications, that
demand additional bandwidth
■
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

LAN
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.
