Glossary: Company 54g Wireless LAN (WLAN) User Manual
access point
A stand-alone wireless hub that allows any computer that has a wireless network 
adapter to communicate with another computer and to connect to the Internet.
ad hoc (also known as computer-
to-computer network)
A communication configuration in which every computer has the same capabilities 
and any computer can initiate a communication session.
available network
One of the networks listed under Wireless Network Connection Properties. Any 
wireless network that is broadcasting and is within receiving range of the 
Company 54g enabled notebook appears on the list.
BER
Bit error rate. The ratio of errors to the total number of bits being sent in a data 
transmission from one location to another.
client computer
The computer that gets its Internet connection by sharing either the host 
computer's connection or the access point's connection.
dBm
A unit of expression of power level in decibels with reference to a power of 1 
milliwatt.
DBPSK
differential-binary-phase-shift keying.
DQPSK
differential-quadrature-phase-shift keying. A compression technique that transmits 
only the differences between the values of the phase of the sine wave rather than 
the full absolute value.
DSSS
direct sequence spread spectrum. A type of radio technology used in wireless 
local area networks. DSSS operates by spreading a signal over a wide range of 
the 2.4-GHz band.
Dynamic Host Configuration 
Protocol (DHCP)
A mechanism for allocating IP addresses dynamically so that addresses can be 
reused when hosts no longer need them.
file and printer sharing
A capability that allows a number of people to view, modify, and print the same 
file(s) from different computers.
GHz
gigahertz. A unit of frequency equal to 1 000 000 000 cycles per second.
host computer
The computer that is directly connected to the Internet via a modem or network 
adapter.
IEEE
Institute of Electrical and Electronics Engineering
Internet Protocol (IP) address
The address of a computer that is attached to a network. Part of the address 
designates which network the computer is on, and the other part represents the 
host identification.
LAN
local area network
m
meter
MHz
megahertz. A unit of frequency equal to 1 000 000 cycles per second.
Mbps
megabits per second. Transmission speed of 1 000 000 bits per second.
ns
nanosecond. 1 billionth (1/1 000 000 000) of a second.
