Glossary
Ad-hoc : Devices in an ad-hoc wireless network communicate directly (“peer to peer”),
without a wireless access point.
AES (Advanced Encryption Standard) : An encryption standard developed for use by the
American government. AES has been praised for combining strong encryption
with rapid processing.
Auto IP (APIPA—Automatic Private IP Addressing) : Allows devices in a network to
automatically assign themselves unique IP addresses if no DHCP server is found
on the network. Auto IP uses addresses from 169.254.1.0 to 169.254.254.255 and a
subnet mask of 255.255.0.0. These addresses are neither global nor private but are
reserved for Auto IP.
BSS-ID (Basic Service Set ID) : All wireless devices on an ad-hoc wireless network share
the same BSS-ID. The BSS-ID may be up to thirty-two characters long and is case
sensitive.

.
Channel : When multiple wireless LANs with diff erent ESS-IDs are operating on a
single frequency within a given area, transmission speeds will drop. Specifying
a separate channel (frequency) for each network can prevent interference and
increase transmission speeds (note that all devices in the same network must be set
to the same channel). In the IEEE 802.11b/g standard, the 2.4 GHz band is divided
into 14 channels, each separated by 4 MHz.
DHCP (Dynamic Host Confi guration Protocol) Server : Each device in a TCP/IP network
requires an IP address. If a DHCP server is present on the network, IP addresses will
be assigned automatically.
DNS (Domain Name Server) : A server that contains a database of IP addresses and host
names for the machines it administers and that converts host names to IP addresses
in response to queries from clients. Each DNS can also query other Domain Name
Servers for addresses not listed in its database.
ESS-ID (Extended Service Set ID) : Multiple BSSs can be confi gured to form an ESS,
allowing users to roam between wireless access points. Only devices with the same
ESS-ID as a given access point can communicate with that access point. The ESS-ID
may be up to thirty-two characters long and is case sensitive.
