Wireless Basics 
The C54U is based on industry standards to provide easy-to-use and 
compatible high-speed wireless connectivity within your home or business. 
Strictly adhering to IEEE 802.11g, the C54U will allow you to access the 
data you want, when and where you want it. No longer will you be limited 
to one location or forced to run new wiring through your home or office. 
You will be able to enjoy the freedom that wireless networking delivers. 
A wireless LAN (WLAN) is a cellular computer network that transmits and 
receives data with radio signals instead of wires. Wireless LANs are used 
increasingly in both home and office environments. Innovative ways to 
utilize WLAN technology are helping people to work and communicate 
more efficiently. Increased mobility and the absence of cabling and other 
fixed infrastructure has proven to be beneficial for many users. 
Wireless users can use the same network applications they use on an 
Ethernet LAN. Wireless adapters used on laptop and desktop systems, 
support the same protocols as Ethernet adapter cards. For most users, 
there is no noticeable functional difference between a wired Ethernet 
desktop computer and a computer equipped with a wireless adapter - 
other than the added benefit of the ability to roam within the wireless cell. 
Under many circumstances, it may be desirable for mobile network devices 
to link to a conventional Ethernet LAN in order to use servers, printers or 
an Internet connection supplied through the wired LAN. A Wireless Access 
Point (AP) is a device used to provide this link. 
People use wireless LAN technology for many different purposes.  
Mobility - Productivity increases when people have access to data in any 
location within the operating range of the WLAN. Ad-hoc management 
decisions based on real-time information can significantly improve worker 
efficiency. 
Low Implementation Costs - WLANs are easy to set up, manage, change 
and relocate. Networks that frequently change, both physically and 
logically, can benefit from WLANs’ ease of implementation. WLANs can 
operate in locations where installation of wiring may be impractical.
