RF

roaming

RP-TNC

A linear measure of the distance that a transmitter can send a signal.

Root Access Point

A measurement of the weakest signal a receiver can receive and still correctly translate it into data.

Radio frequency. A generic term for radio-based technology.

A feature of some access points that allows users to move through a facility while maintaining an unbroken connection to the LAN.

A connector type unique to Cisco Aironet radios and antennas. 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 Aironet, 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

spread spectrum

SSID

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.
