Thank you for purchasing the Philips Wireless USB Adapter 11g True Turbo
108 Mbps. This Wireless USB Adapter 11g True Turbo 108 Mbps is a WiFi (IEEE 802.11g) compatible USB device. It fully supports high data rates up to 108 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
USB Adapter 11g True Turbo 108 Mbps.
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 802.11g 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 108 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.
•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.
For an example of how to secure your network, please see the chapter Securing your wireless network.
