C. Glossary
Access Point — An internetworking device that seamlessly connects wired and wireless
networks together.
Association — The process used by wireless clients to find an Access Point with which
to communicate.
Bandwidth — The size (in Hertz) of the frequency range that a signal transmission
occupies. Typical narrow band signals occupy a 25 KHz bandwidth. The
RangeLAN802 signal occupies a 1 MHz bandwidth.
BOOTP (Bootstrap Protocol) — A protocol used to assign IP addresses.
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) — CSMA is a
protocol in which each node senses whether or not a channel is in use before attempting
to transmit information. CA is an optimization by which channel time is reserved to
avoid collisions.
Download Image — A software file that is used to upgrade the software code running
on the RangeLAN802 Access Point.
ESSID (Extended Service Set ID) — A string that must match on all communicating
RangeLAN802 products.
Frequency Hopping — A spread spectrum technique by which the band is divided into
a number of channels and the transmissions hop from channel to channel in a pre-speci-
fied sequence.
Hopping Pattern — A hopping sequence as specified in the IEEE 802.11 specifica-
tion.
IEEE — The Institute of Electrical and Electronics Engineers, a trade organization and
standards body.
Interference — A situation that occurs when an unwanted RF signal occupies the same
frequency band as a desired signal.
