Wireless Basics
The 802.11g USB Adapter is based on industry standards to provide easyto-
use and compatible high-speed wireless connectivity within your home or
business. Strictly adhering to IEEE 802.11g, the 802.11g USB Adapter 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. Furthermore, IEEE
8
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 802.11g USB Adapter 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), 802.11g USB Adapter lets you
access your network with your laptop computer from virtually anywhere you
9
want. Keep in mind, however, that the number and thickness of walls,
ceilings or other objects that the wireless signals must pass through may
limit range. Typical ranges vary depending on the types of materials and
background RF (radio frequency) noise in your home or business. The key to
maximizing range is to follow these basic principles:
1. Keep the number of walls and ceilings between the Access Point and
your receiving device to a minimum - each wall or ceiling can reduce
your 802.11g USB Adapter’s range from 3-90 feet (1-30 meters.) For
some businesses or for a large residential home deployment, it may be
beneficial to have more than one access point with overlapping coverage.
2. Be aware of the direct line between Access Points and computers with
wireless adapters - a wall that is 1.5 feet thick (.5 meters), at a 45-degree
angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it
looks over 42 feet (14 meters) thick! Try to make sure that the Access
Points and adapters are positioned so that the signal will travel straight
through a wall or ceiling for better reception.
3. Building materials make a difference - a solid metal door or aluminum
studs may have a negative effect on range. Try to position Access Points,
and computers with wireless adapters so that the signal passes through
drywall or open doorways and not other materials.
5. Keep the 802.11g USB Adapter away (at least 3-6 feet or 1-2 meters)
from electrical devices or appliances that generate extreme RF noise.
For the average residence, range should not be a problem. If you experience
low or no signal strength in areas of your home that you wish to access,
consider positioning the Access Point in a location directly between the
computers with wireless adapters that will be connected. Additional Access
Points can be connected to provide better coverage in rooms where the
signal does not register as strongly as desired.
