Glossary
802.11: IEEE 802.11 specifications are wireless standards that specify an over-the-air interface between a wireless client
and a base station or between two wireless clients, such as the LiteShow adapter and a computer’s wireless adapter.
Access point: A base station in a wireless LAN. LiteShow does not require an access point, but it does support infra-
structure mode and can use an access point.
Ad-hoc Mode: Ad-hoc mode, also known as “peer-to-peer” mode, allows wireless devices to communicate with each
other directly and without the need of an access point. This is an Independent BSS (IBSS).
Advanced Feature set: LiteShow has the ability to switch from one network to another and to find available projec-
tors on other networks via the LiteShow Manager's Scan button. This is known as the Advanced Feature set.
Authentication: The process of identifying an individual, usually based on a username and password. Two examples
are Shared Key and Open Key.
Basic Feature set: Some wireless cards do not support advanced network switching, although you can still project
using LiteShow. With basic network switching the Scan button is not operational and the WLAN column is not dis-
played in the List Window. This is known as the Basic Feature set.
BSS: In 802.11 systems, each access point and each wireless device are known as a Basic Service Set (BSS).
DCHP: Dynamic Host Configuration Protocol. DHCP's purpose is to enable individual computers on an IP network to
extract their configurations from a server.
Encryption: The process of encoding data so that it is inaccessible during transmission.
Firmware: A type of memory chip that retains its content without electrical power.
IBSS: In ad hoc mode wireless devices can communicate with each other directly and do not use an access point. This
is known as an Independent Basic Service Set (IBSS).
DCHP: Also know as Dynamic Host Configuration Protocol software. DHCP automatically assigns IP addresses to cli-
ent stations logging onto a TCP/IP network. It eliminates the need to manually assign permanent IP addresses.
