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.
