Wireless LAN
The Access Point
B.3 The Access Point
An Access Point is similar to a hub. It connects computers to each other
and to a network. It functions as a node in a network. Only the Access
Points on a Wireless LAN require cabling.
An Access Point in itself cannot give access to the Internet because data
exchange with the Internet needs to be routed through a gateway.
Whether an Access Points also gives access to the Internet depends on
its firmware.
Different types of Access Points can use different types of Radio
Frequency signals that are not compatible. It is recommended to check
whether the type of Wireless LAN and your PC card are compatible
when you connect in a unfamiliar network environment.
B.4 Service Set ID (SSID)
The Service Set ID is the name of your wireless network that you
connect to.
All the wireless devices connected to each other must share this SSID.
B.5 Physics of an Access Point
B.5.1 Range
A wireless LAN device uses RF waves (Radio Frequency) to transmit
and receive data. The range of the propagated power depends on the
device and the environment. Indoor environments contain objects such
as walls, metal objects, and even people that can effect the propagation
of the radiated power.
Although RF energy can penetrate through most indoor walls and other
obstacles, these obstacles may influence the quality of the signal of the
wireless device.
When placing wireless LAN device you must consider all possible
obstacles and test the range of the device using a client device to make
a connection and moving around to test the strength of the signal.
When you place more than one wireless LAN device, consider the range
that each device covers.
For the range of your device(s); see the specifications of your device.
B.5.2 Data rates
Wireless LAN devices operate at much faster speeds than modems.
The data rates on a wireless link are determined by:
