than in the case of narrowband transmission, but the trade off produces a signal
that is, in effect, louder and thus easier to detect, provided that the receiver knows
the parameters of the spread-spectrum signal being broadcast. If a receiver is 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 uses TKIP
(Temporal Key Integrity Protocol) encryption, which can be used in conjunction
with a RADIUS server.
