Chapter 1 - Introduction of the Wireless Notebook Adapter 11a/g
CPWNA100
Thank you for purchasing the Philips Wireless Notebook Adapter 11a/g.This
Wireless Notebook Adapter 11a/g is a WiFi (IEEE 802.11a/g) compatible
Notebook device. It fully supports high data rates up to 54 Mbps with
automatic fallback to lower speeds for secure operation at lower data rates
in even the most difficult of wireless environments.
In this manual we will expand on how to install, configure, and use your
Wireless Notebook Adapter 11a/g.
This chapter will give you background information on wireless networks and
their security in general.
What are wireless network connections?
Your wireless network adapter uses a wireless protocol
(called IEEE 802.11a/g 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 100 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.
