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 (PDUs) 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 the 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 are 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 builds 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.
