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:
SSID (Service Set Identifier) 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.
WPA/WPA2 Encryption:
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.
802,1x authentication
Static WEP key is difficult to manage for when you change the key, you will have to
inform all others, and if the key is disclosed in one of the places, the key can no longer
provide security. Besides, there's severe security loophole about static WEP encryption.
The WEP key can be decrypted after one person receives a specific amount of data via
wireless intercepting. 802,1x is initially used for wired Ethernet authentication access to
prevent illegal users from accessing the network. Later, it is found that 802.1x can better
solve the wireless network security problem. EAP-TLS of the 802.1x successfully
achieves the two-way authentication between users and networks, i.e. can prevent
illegal users from accessing the network and can also prevent users from accessing the
illegal AP. 802.1x utilizes dynamic WEP encryption to protect the WEP key from being
decrypted. To solve the publishing problem for digital certification, people make some
changes to TLS authentication and TTLS and EAP come into exist, which enable you to
access the network by using the traditional way of authentication: username and
password.
