Cisco Systems OL-6415-04 While maintaining an unbroken connection to the LAN, That of a cable

Glossary

roaming	A feature of some Access Points that allows users to move through a facility
	while maintaining an unbroken connection to the LAN.
RP-TNC	Reverse Polarity Threaded Neill Concelman connector. Part 15.203 of the FCC
	rules covering spread spectrum devices limits the types of antennas that may be
	used with transmission equipment. In compliance with this rule, Cisco, like all
	other wireless LAN providers, equips its radios and antennas with a unique
	connector to prevent attachment of non-approved antennas to radios.

S

slot time

spread spectrum

SSID

The amount of time a device waits after a collision before retransmitting a packet. Short slot times decrease the backoff time, which increases throughput.

A radio transmission technology that spreads the user information over a much wider bandwidth than otherwise required in order to gain benefits such as improved interference tolerance and unlicensed operation.

Service Set Identifier (also referred to as Radio Network Name). A unique identifier used to identify a radio network and which stations must use to be able to communicate with each other or to an access point. The SSID can be any alphanumeric entry up to a maximum of 32 characters.

T

transmit power

U

UNII

UNII-1

UNII-2

UNII-3

unicast packet

The power level of radio transmission.

Unlicensed National Information Infrastructure—regulations for UNII devices operating in the 5.15 to 5.35 GHz and 5.725 to 5.825 GHz frequency bands.

Regulations for UNII devices operating in the 5.15 to 5.25 GHz frequency band.

Regulations for UNII devices operating in the 5.25 to 5.35 GHz frequency band.

Regulations for UNII devices operating in the 5.725 to 5.825 GHz frequency band.

A single data message (packet) sent to a specific IP address.

W

WEP	Wired Equivalent Privacy. An optional security mechanism defined within the
	802.11 standard designed to make the link integrity of wireless devices equal to
	that of a cable.
