signal used to synchronize the transmission timing between two or more systems. A series of
transmission pulses is sent before the data to indicate that “someone is about transmit data.” This
ensures that systems receiving the information correctly when the data transmission starts.
S
Shared Key - Is when both the sender and recipient share a secret key. Both units use this key for
an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may
decipher all packets until the key is changed.
Signal Strength - The signal level indicates the strength of the signal as received at the wireless
network interface.
SNMP ( S imple N etwork M anagement P rotocol) - A standard network protocol that can be used
to manage networks locally, or worldwide via the Internet.
SSID ( S ervice S et I dentifier) - Is the unique name shared among all points in a wireless network.
The SSID must be identical for all points in the network. It is case sensitive and must not exceed
32 characters.
Static IP Address - A permanent IP address that is assigned to a node in an IP or a TCP/IP
network.
Subnet - A subnet is a logical sub-division of a Local Area Network that has been divided by
means of routers or gateways. A subnet may include multiple LAN segments. Each subnet is
identified by the Subnet Mask.
T
TCP/IP ( T ransmission C ontrol P rotocol/ I nternet P rotocol) - The basic communication language
or protocol of the Internet. It can also be used as a communications protocol in a private network
(either an intranet or an extranet). When you are set up with direct access to the Internet, your
computer is provided with a copy of the TCP/IP program just as every other computer that you
may send messages to or get information from also has a copy of TCP/IP.
Throughput - The amount of data moved successfully from one place to another in a given time
period.
Tx Rate - Transmission Rate.
W
WEP ( W ired E quivalent P rivacy) - The optional cryptographic confidentiality algorithm
specified by IEEE 802.11 used to provide data confidentiality that is subjectively equivalent to
the confidentiality of a wired LAN medium that does not employ cryptographic techniques to
enhance privacy.
Windows workgroup - A Windows workgroup can consist of either wireless or wired network
connections or a combination of the two. Usually a Windows workgroup consists of members
who are related because of a shared function, e.g. members of the same department. For a
Windows workgroup it is not relevant where the workgroup participants are located, since the
members of a Windows workgroup are identified by their workgroup name only.
