The contributor also acknowledges and accepts that this contribution may be made public by IEEE Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE TAG.

Submission doc.: IEEE /0128r1 Slide 4 [1] TV Band (White Spaces) Database Administrators Guide, whitespace/tvwpdda.htmlhttp://transition.fcc.gov/oet/ whitespace/tvwpdda.html FCC : Second report and order and memorandum opinion and order, Nov, 2008 [2] FCC : Second memorandum opinion and order, Sep, 2010 [3] Proposal by Google Inc. to provide a TV band device database management solution, Google Inc., Jan Supplement to proposal to be designated TV band device database manager, Airity Inc. Feb Comsearch proposal to be designated as a TV band device database manager, Comsearch, Jan White space proposal by KB Enterprises LLC and LS telecom, KB Enterprises LLC, LS telcom AG, Jan Proposal to administer a TV bands database, Key Bridge Global LLC, Jan TV White Space Database Activities (FCC) Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Key issues of geo-location database Key issues to be addressed in developing a geo-location approach are given as follows: –Database topology –Database information from WSDs –Database information to WSDs –Database update frequency –Database architecture Slide 5 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database topology (FCC) More than one database[1] –FCC chooses multiple open database operated by third parties –9 companies submitted proposal for designated TV white space database administrators Multiple database administrators could offer services on a competitive basis The services must be available to all TV band devices users on a non- discriminatory basis In the case of multiple database administrators, must be ensured that each database contains consistent information, that is receiving same sets of available channels regardless of which database it queries Slide 6 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database information from WSDs (FCC) The following information needs to be provided by the WSDs to the geo-location database [2] : –Fixed and Mode II TVBDs must provide their location identifying information (i.e., FCC ID) Slide 7 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database information from WSDs (FCC) TVBD registration database shall contain the following information for fixed TVBDs [2] : –FCC identifier (FCC ID) of the device –Manufacturer’s serial number of the device –Device’s geographic coordinates (latitude and longitude accurate to 50m) –Device’s antenna height above ground level –Name of the individual or business that owns the device –Names of a contact person responsible for the device’s operation –Address for the contact person – address for the contact person –Phone number for the contact person Slide 8 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database information to WSDs (FCC) The following information needs to be provided by the geo- location database to the WSDs [2] : –Fixed TVBDs register and receive a list of available channels from the database by connecting to the internet, either directly or through another fixed TVBD that has a direct connection to the Internet –Mode II TVBDs receive a list of available channels from the database by connecting to the internet, either directly or through a fixed or Mode II TVBD that has a direct connection to the internet Slide 9 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database update frequency (FCC) Database update frequency in FCC is given as follow [2] –Minimum check database on a daily basis over the internet –If a device fails to access database will be stopped with a one-day period –In order for a device to get updated information from database it will required to provide Location Identification information If fixed device any changes in the registration information –For personal/portable devices it is required that are accessing the database for update when are activated or move Slide 10 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database architecture (FCC) Multiple database administrators that could offer services on a competitive basis The 9 designated TV white space database administrators are [1][3]: –Airity, –Comsearch –Frequency Finder –Google –KB Enterprises LLC and LS Telecom –Key Bridge Global LLC –NeuStar –Spectrum Bridge –Telcordia Technologies Slide 11 Nov Donghun Lee, et al, ETRI

Submission doc.: IEEE /0128r1 Database architecture (FCC) ‘Clear house’ model proposed by Google [3] –The ‘clear house’ model partitions the process of providing information on available channels to WSDs –The key element is the clearing house, which aggregates and hosts the raw data needed to perform database calculations. –The TVWS database service providers would use the raw data together with other required regulatory inputs in the process of calculating the contents of their own databases The clearinghouse model would provide substantial benefits, including, facilitating greater choice in service providers, and minimizing the burden of syncing with multiple parties. It would leave open the possibility of approving quickly other clearinghouse and TVWS Database Service proposals, leading to more robust market forces and promoting innovation and competition in basic and enhanced database services.
