not tuned to the right frequency, a spread-spectrum signal looks like background noise. There
are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency
Hopping Spread Spectrum (FHSS).
SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric key
identifying a wireless local area network. For the wireless devices in a network to
communicate with each other, all devices must be configured with the same SSID. This is
typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in
the wireless Access Point and to the wireless network name. See also Wireless Network
Name and ESSID.
WEP - (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or
152-bit shared key algorithm, as described in the IEEE 802.11 standard. To gain access to a
WEP network, you must know the key. The key is a string of characters that you create. When
using WEP, you must determine the level of encryption. The type of encryption determines
the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are
defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII
(American Standard Code for Information Interchange – alphanumeric characters) format.
ASCII format is provided so you can enter a string that is easier to remember. The ASCII
string is converted to HEX for use over the network. Four keys can be defined so that you can
change keys easily.
Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the Wireless
Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an industry standards group
promoting interoperability among 802.11b devices.
WLAN - (Wireless Local Area Network) - A group of computers and associated devices
communicate with each other wirelessly, which network serving users are limited in a local
area.
WPA - (Wi-Fi Protected Access) - A wireless security protocol use TKIP (Temporal Key
Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.
