Appendix I: Glossary
Access Point (AP)
:
Any entity that has station functionality and provides access to the
distribution services, via the wireless medium (WM) for associated
stations.
Channel
:
An instance of medium use for the purpose of passing protocol data
units (PDU’s) that may be used simultaneously, in the same volume of
space, with other instances of medium use (on other channels) by
other instances of the same physical layer (PHY), with an acceptably
low frame error ratio (FER) due to mutual interference.
SSID:
Service Set identifier. An SSID is the network name shared by all
devices in a wireless network. Your network’s SSID should be unique
to your network and identical for all devices within the network. It is
case-sensitive and must not exceed 20 characters (use any of the
characters on the keyboard). Make sure this setting is the same for all
devices in your wireless network.
WEP:
Wired Equivalent Privacy (WEP) is a method for secure wireless data
transmission.
WEP adds data encryption to every single packet
transmitted in the wireless network.
The 40bit and 64bit encryption are
the same because of out 64 bits, 40 bits are private.
Conversely, 104
and 128 bit is the same.
WEP uses a common KEY to encode the
data.
Therefore, all devices on a wireless network must use the same
key and same type of encryption.
There are 2 methods for entering the
KEY; one is to enter a 16-bit HEX digit.
Using this method, users must
enter a 10-digit number (for 64-bit) or 26-digit number (for 128-bit) in
the KEY field.
Users must select the same key number for all
devices.
The other method is to enter a text and let the computer
generate the WEP key for you.
However, since each product use
different method for key generation, it might not work for different
products.
Therefore, it is NOT recommend using.
WPA/WPA2:
A security protocol for wireless networks that build on the basic
foundations of WEP. It secures wireless data transmission by using a
key similar to WEP, but the added strength of WPA is that the key
changes dynamically. The changing key makes it much more difficult
for a hacker to learn the key and gain access to the network. WPA2 is
the second generation of WPA security and provides a stronger
encryption mechanism through Advanced Encryption Standard (AES),
which is a requirement for some government users.
ADSL
Short for Asymmetric Digital Subscriber Line -- A method for moving
data over regular phone lines. An ADSL circuit is much faster than a
regular phone connection, and the wires coming into the subscriber's
premises are the same (copper) wires used for regular phone service.
A commonly discussed configuration of ADSL would allow a subscriber
to receive data (download) at speeds of up to 1.544 megabits (not
megabytes) per second, and to send (upload) data at speeds of 128
kilobits per second.
