Device-to-Device Network (Peer-to-Peer Network)
Two or more devices that connect using wireless network devices without the
use of a centralized wireless access point. Also known as a peer-to-peer
network.
DHCP
The dynamic host configuration protocol is an Internet protocol, similar to BootP,
for automating the configuration of computers that use TCP/IP. DHCP can be
used to automatically assign IP addresses, to deliver IP stack configuration
parameters, such as the subnet mask and default router, and to provide other
configuration information, such as the addresses for printer, time, and news
servers.
Direct Sequence Spread Spectrum
One of two approaches (with frequency hopping spread spectrum) for sorting out
overlapping data signals transmitted via radio waves. 802.11b uses DSSS
Directional Antenna
Transmits and receives radio waves off the front of the antenna.
Diversity Antenna
An antenna system that uses multiple antennas to reduce interference and
maximize reception and transmission quality.
DTE
Data Terminal Equipment, for example, a computer or terminal.
Dual Band
A device that is capable of operating in two frequencies. On a wireless network,
dual-band devices are capable of operating in both the 2.4 GHz (802.11b/g) and
5 Hz (802.11a) bands.
E
EAP
Extensible Authentication Protocol. A protocol that provides an authentication
framework for both wireless and wired Ethernet enterprise networks.
EIRP
Equivalent isotropically radiated power (EIRP) is the amount of power that would
have to be emitted by an isotropic antenna (that evenly distributes power in all
directions and is a theoretical construct) to produce the peak power density
observed in the direction of maximum antenna gain.
Encryption
Method of scrambling data so that only the intended viewers can decipher and
understand it.
