Signal Strength - The signal level indicates the strength of the signal as received at the
wireless network interface.
SNMP (Simple Network Management Protocol) - A standard network protocol that can be
used to manage networks locally, or worldwide via the Internet.
Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique
developed by the military for use in reliable, secure, mission-critical communication 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. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and
Frequency Hopping Spread Spectrum (FHSS).
SSID (Service Set Identifier) - 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 (Transmission Control Protocol/Internet Protocol) - 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.
W
WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 40 bit shared key
algorithm, as described in the IEEE 802 .11 standard. 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.
