What are wireless network connections?
Your wireless network adapter uses a wireless protocol (called IEEE 802.11b
or WiFi) to communicate with other network computers by means of radio
transmissions. WiFi radio waves travel outwards from the antenna in all
directions, and can transmit through walls and floors. Wireless transmissions
can theoretically reach up to 450 meters in an open environment and reach
speeds of up to 11 megabits per second (Mbps) at close range. However,
the actual network range and data throughput rate will be less, depending
on the wireless link quality.
Factors determining your network range and network speed
• The environment: Radio signals can travel farther outside of buildings,
and if the wireless components are in direct line of sight to one another.
Putting wireless components in high places helps avoid physical obstacles
and provides better coverage.
• Building construction such as metal framing and concrete or masonry
walls and floors will reduce radio signal strength. Avoid putting wireless
components next to walls and other large, solid objects; or next to large
metal objects such as computers, monitors, and appliances.
• Wireless signal range, speed, and strength can be affected by
interference from neighbouring wireless networks and devices. Electro-
magnetic devices such as televisions, radios, microwave ovens, and
cordless phones, especially those with frequencies in the 2.4 GHz range,
may also interfere with wireless transmission.
• Standing or sitting too close to wireless equipment can also affect radio
signal quality.
• Adjusting the antenna: Do not place antennas next to large pieces of
metal, because this might cause interference.
Securing your wireless network
As wireless computer networks use radio signals, it is possible for other
wireless network devices outside your immediate area to pick up the
wireless signals and either connect to your network or to capture the
network traffic.Therefore, you should always enable the Wired Equivalent
Privacy (WEP) or WiFi Protected Access (WPA) network encryption key
to help prevent unauthorised connections or the possibility of
eavesdroppers listening in on your network traffic.
