What is the correct term for something that is operating as a license-exempt device - yet has been given short term authorization to share a channel with other license-exempt devices based on a query to a regional authorities database in a portion of spectrum that may also include licensed or light-licensed devices at other times or in other areas.

This is usually done through auctions (think of the Telcos), beauty contest, first-come / first-served or by government allocation (e.g., public service). Lightly licensed: Special case where thefrequency allocation is done through first-come / first-served process for a given time frame over a relatively limited service area. The annual license fee is usually small to facilitate the deployment of a service that would not normally be economically attractive. Small local operators would be interested by this (e.g., rural broadband in Canada) and not big Telcos that would normally work with full licensing through auction over large service areas. License-exempt: Operation of RF devices in a frequency band where no formal licensing process is needed such as in the 2.4 GHz ISM band. In the USA, this term is used for a specific type of operation. The FCC should be contacted to clarify it. Unlicensed: Illegal operation of an RF device that can transmit in a frequency band without a duly issued license. In the USA, this term is used to mean "license-exempt," see above. To my knowledge, the term "unlicensed" is used only in the USA to describe a legal operation because the term "license-exempt" has been used for another specific purpose. Since the PAWS addresses the interface to the database for the international market, it should rely on the definition of the terms recognized by the ITU-R. I would suggest the use of 'licensed' and 'license-exempt' with a footnote indicating that the term 'unlicensed' is used in the USA instead of the usual 'license-exempt'.
