APPENDIX C: GLOSSARY
Access Point ?
An internetworking device that seamlessly connects wired and
wireless networks.
Ad-Hoc ? An independent wireless LAN network formed by a group of computers,
each with an network adapter.
AP Client – One of the additional AP operating modes offered by 22Mbps Access
Point, which allows the Access Point to act as an Ethernet-to-Wireless Bridge, thus a
LAN or a single computer station can join a wireless ESS network through it.
Authentication Type ? Indication of an authentication algorithm which can be
supported by the Access Point:
1. Open System : Open System authentication is the simplest of the available
authentication algorithms. Essentially it is a null authentication algorithm.
Any station that requests authentication with this algorithm may become
authenticated if 802. 11 Authentication Type at the recipient station is set to
Open System authentication.
2. Shared Key : Shared Key authentication supports authentication of stations
as either a member of those who know s a shared secret key or a member of
those who does not.
Backbone ? The core infrastructure of a network, which transports information from
one central location to another where the information is unloaded into a local system.
Bandwidth ? The transmission capacity of a device, which is calcula ted by how
much data the device can transmit in a fixed amount of time expressed in bits per
second (bps).
Basic Rate ? the fixed transmitted and receiving data rate allowed by the AP with
the value 1,2,5.5, 11 and 22 Mbps for selection.
Beacon ? A beacon is a packet broadcast by the Access Point to keep the network
synchronized. Included in a beacon are information such as wireless LAN service
area, the AP address, the Broadcast destination addresses, time stamp, Delivery
Traffic Indicator Maps, and the Traffic Indicator Message (TIM).
Bit ? A binary digit, which is either -0 or -1 for value, is the smallest unit for data.
