wireless 802.11 LANs operate at 2.4GHz.
Roaming
The ability to use a wireless device and move from one access point’s range to
another access point without a drop or loss of connection.
Shared Key Algorithm
In encryption, both the sender and the recipient use the same secret key to both
encode and decode a message.
Spread Spectrum
Spread Spectrum technology is a wideband radio frequency technique developed
by the military for use in reliable, secure, mission-critical communications
systems. It is designed to trade off bandwidth efficiency for reliability, integrity,
and security. In other words, more bandwidth is consumed 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.
SSID
(Service Set ID)
A group name shared by every member of a wireless network. Only client PCs
with the same SSID are allowed to establish a connection.
Static IP address
A static IP address is an IP address that does not change and is manually set in
client computer or router in a LAN or WAN.
TCP/IP
Acronym for Transmission Control Protocol/Internet Protocol, the basic protocol
of the Internet, which can be used as a communications protocol in a private
network. Every computer that has direct access to the Internet has a copy of the
TCP/IP program. TCP/IP uses the client/server model in which the user is the
client that requests and is provided service by another computer, which is the
server on a network. HTTP, FTP, Telnet, SMTP and other protocols are often
packaged with TCP/IP as a “suite” in order to get to the Internet.
URL
A URL (Uniform Resource Locator) is the address of a file (resource) accessible
on the Internet. The URL contains the name of the protocol required to access
the resource, a domain name that identifies a specific computer on the Internet,
and a hierarchical description of a file location on the computer.
WLAN
A WLAN in which a user can connect to a network using a wireless connection.
IEEE 802.11 specifies the technology for WLANs, as well as the Wired
Equivalent Privacy algorithm encryption method.
WEP
(Wired Equivalent Privacy)
A data privacy encryption method based on a 64-bit shared key algorithm.
