A basic message unit for communication across a network. A packet usually includes routing
Packet
information, data, and sometimes error detection information.
Pocket-sized Personal Computer. One of the three defined types of Windows CE devices.
PPC
Q
Quadruple phase shift keying. A modulation technique used by IEEE 802.11-compliant wireless LANs
QPSK
for transmission at 2 Mbps.
R
The frequency at which a radio operates.
Radio Channel
A linear measure of the distance that a transmitter can send a signal.
Range
A measurement of the weakest signal a receiver can receive and still correctly translate it into data.
Receiver Sensitivity
Radio frequency. A generic term for radio-based technology.
RF
A feature of some access points that allows users to move through a facility while maintaining an
Roaming
unbroken connection to the LAN.
The packet size at which an access point will issue a request to send (RTS) before sending the packet.
RTS Threshold
S
A radio transmission technology that spreads the user information over a much wider bandwidth than
Spread Spectrum
otherwise required in order to gain benefits such as improved interference tolerance and unlicensed
operation.
Service set identifier. A unique identifier that stations must use to be able to communicate with an
SSID
access point. The SSID can be any alphanumeric entry up to a maximum of 32 characters.
T
Temporal Key Integrity Protocol. Also referred to as WEP key hashing. A security feature that defends
TKIP
against an attack on WEP in which the intruder uses the initialization vector (IV) in encrypted packets
to calculate the WEP key. TKIP removes the predictability that an intruder relies on to determine the
WEP key by exploiting IVs.
The power level of radio transmission.
