| 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 peer-to-peer 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 in the Available networks
list on the Wireless Networks tab of the Wireless Configuration
box that appears when the TrueMobile WLAN Card Utility is open. Any wireless
network that is broadcasting and is within receiving range of the Dell TrueMobile
WLAN Card 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. |
| 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. |
| OFDM |
orthogonal frequency division multiplexing |
| preferred network |
One of the networks that you have configured. Such networks
appear in the Preferred networks list on the Wireless Networks
tab of the Wireless Configuration box when the TrueMobile WLAN Card
Utility is open. |
| Service Set Identifier (SSID) |
A value that controls access to a wireless network. The SSID
for your wireless network card must match the SSID for any access point
that you want to connect with. If the value does not match, you are not
granted access to the network. You can have up to three SSIDs. Each SSID
can be up to 32 characters long and is case-sensitive. |
| Wired Equivalent Privacy (WEP) |
A form of data encryption. You must set the WEP key information
in the client to match the WEP key used by the access point. The WEP key
can be enabled or disabled. The WEP key is case-sensitive. |
