Hello All,
As editors of the problem statement, use cases & requirements draft we are
attempting to prepare a completed draft which could be ready for working
group last call before IETF83. In the coming days we will post the
sections of the draft to the mailing list. Our request is that you review
these sections and reply to the email with any comments.
Below is the text for sections 9 and 11. This text has not changed from
version-02 as uploaded January 26, 2012. Our goal is that any discussion
on this text will conclude by February 6. To be clear, approval of the
document will go through the normal process of last calls etc.. We are
simply asking for your assistance in preparing a complete & accurate
document that could progress the work. So please review the text and send
your comments either directly to the editor or to the mailing list.
Kind Regards,
Raj & Scott
9. Summary and Conclusion
Wireless spectrum is a scarce resource. As the demand for spectrum
grows, there is a need to more efficiently utilize the available and
allocated spectrum. Cognitive radio technologies enable the
efficient usage of spectrum via means such as sensing or by querying
a database to determine available spectrum at a given location for
secondary use. White space is the general term used to refer to the
bands within the spectrum which is available for secondary use at a
given location. In order to use this spectrum a device needs to
query a database which maintains information about the available
channels within a band. A protocol is necessary for communication
between the devices and databases which would be globally applicable.
The document describes some examples of the role of the white space
database in the operation of a radio network and also shows an
examples of a services provided to the user of a TVWS device. From
these use cases requirements are determined. These requirements are
to be used as input to the definition of a Protocol to Access White
Space database (PAWS).
