Instruction Manual TWL54A Access Point
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 idertical 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 to use.
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.
