frequency, it must sense the presence of radar and automatically change to another
channel if radar is detected.
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 GHz
(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.
