Network Hardware User Manual

Furthermore, IEEE standardization mandates interoperability of all WLAN

devices that conform to the 802.11g set of standards.

Installation Speed and Simplicity - Installing a wireless LAN system can be

fast and easy and can eliminate the need to pull cable through walls and

ceilings.

Installation Flexibility - Wireless technology allows the network to go

where wires cannot go.

Reduced Cost-of-Ownership - While the initial investment required for

wireless LAN hardware might be higher than the cost of wired LAN

hardware, overall installation expenses and life-cycle costs will be

significantly lower. Long-term cost benefits are greatest in dynamic

environments requiring frequent moves, adds, and changes.

Scalability - Wireless LAN systems can be configured in a variety of

topologies to meet the needs of specific applications and installations.

Configurations are easily changed and range from peer-to-peer networks

suitable for a small number of users to full infrastructure networks of

thousands of users that allow roaming over a broad area.

Standards - Based Technology

The IEEE 802.11g standard designates that devices operate at an optimal

data rate of 54 Megabits per second. This means you will be able to

transfer large files quickly or even watch a movie in MPEG format over

your network without noticeable delays. This technology works by

transmitting high-speed digital data over a radio wave utilizing OFDM

(Orthogonal Frequency Division Multiplexing) technology. OFDM works by

splitting the radio signal into multiple smaller sub-signals that are then

transmitted simultaneously at different frequencies to the receiver. OFDM

reduces the amount of crosstalk (interference) in signal transmissions. The

C54U will automatically sense the best possible connection speed to ensure

the greatest speed and range possible with the technology.

Installation Considerations

Designed to go up to 900 feet (~300 meters), C54U lets you access your

network with your laptop computer from virtually anywhere you want.
