IRE. IEEE is an organization composed of engineers, scientists, and students. The IEEE
is best known for developing standards for the computer and electronics industry.
Infrastructure
An 802.11 networking framework in which devices communicate with each other by
first going through an Access Point (AP). In Infrastructure mode, wireless devices can
communicate with each other or can communicate with a wired network.
IP
Internet Protocol. The standard protocol within TCP/IP that defines the basic unit of
information passed across an Internet connection by breaking down data messages into
packets, routing and transporting the packets over network connections, then
reassembling the packets at their destination. IP corresponds to the network layer in the
ISO/OSI model.
IP Address
An IP Address is a 32-bit number that identifies each sender or receiver of information
sent across the Internet. An IP address has two parts: the identifier of a particular
network on the Internet and an identifier of the particular device (which can be a server
or a workstation) within that network.
LAN
Local Area Network. A communication network that serves users within a defined
geographical area. The benefits include the sharing of Internet access, files, and
equipment, such as printers and storage devices. Special network cabling (such as
10BaseT) is often used to connect the PCs together.
MAC Address
The MAC (Media Access Control) Address is a 12 digit Hexadecimal number that
uniquely identify your network adapter on the network.
Media
The materials used to connect network devices, such as twisted-pair wire, coaxial cables,
or fiber optic cables. Some networks do not use physical connecting media;
communications are achieved via radio waves instead.
Mbps
Stands for millions of bits per second or megabits per second and is a measurement for
data transmission
Protocol
The rules and encoding specifications for sending data.
RF
Radio Frequency, any frequency within the electromagnetic spectrum associated with
radio wave propagation. When an RF current is supplied to an antenna, an
electromagnetic field is created that then is able to propagate through space.
Roaming
In an Infrastructure mode wireless network, roaming refers to the ability to move from
one AP coverage area to another without interruption in service or loss in connectivity.
SSID
Service Set Identifier, up to 32-character unique identifier attached to the header of
packets sent over a WLAN that acts as a password when a mobile device tries to connect
to the BSS. The SSID differentiates one WLAN from another; so all access points and
all devices attempting to connect to a specific WLAN must use the same SSID. A device
will not be permitted to join the BSS unless it can provide the unique SSID. An SSID is
