Unlicensed Wireless Microphone Venue Registration
System

• Original Plan (Workshops)
• FCC would
• Receive a registration request, seek public
  comment, and decide whether to grant the
  request
• For granted requests, maintain a database of
  registered venues that contains data on
  allowable channel use and schedules
• Provide for download by the database
  administrators
• Database administrators would
• Download records for registered venues from
  the FCC database daily
• Provide protection

Unlicensed Wireless Microphone Venue Registration
System

• New Plan
• FCC will
• Receive registration requests, seek public
  comment, and decide whether to grant the
  requests
• For granted requests, maintain a database of
  registered venues that contains data on
  allowable channel use and initial schedules
• Provide for download of approved registrations
  by the database administrators
• Database administrators will
• Download records for registered venues from
  the FCC database daily
• Provide for channel use and schedule updates by
  parties responsible for registered venues
  format the same as for licensed w-m
  registrations but with limitations on channel
  occupancy
• Provide protection

9
Unlicensed Wireless Microphone Venue Registration
System

• Status of FCC Registration System
• System still under development
• - Will discuss database format specifications
  today
• - Application/request screens available
• now
• Target date for activation is February 2012

Licensed and Unlicensed Wireless Microphones
Geographic Locations

• PREVIOUSLY (Workshop 3)
• Question 4 Is there a limit on the number of or
  distance between the geographic coordinates that
  can be registered for a registered venue?
• Answer No and we expect that for large venues
  (golf courses, race tracks, etc.) the number of
  registration points could be relatively high. We
  will also allow specification of protection zones
  with boundaries defined by a series of points
  connected by straight lines.

11
Unlicensed Wireless Microphones

• Geographic Locations
• NEW
• Wireless microphones (licensed and unlicensed)
  can register for protection based on
• a) Specific geographic points (up to 25 may be
  specified on a registration), or
• b) Up to four four-sided polygons, where the
  distance between any two adjacent vertices of a
  polygon is 3 km or less

12
Canadian TV Station Data

• PREVIOUSLY
• Canadian station data to be extracted from CDBS
• Part of OET issued CDBS Extraction Logic
• ISSUE
• Canadians indicated that the CDBS records for
  Canadian stations in many cases do not reflect
  actual station operations
• CDBS records show international agreements
  (i.e., protects allotments)
• Actual station operations are often different
  operating facilities (smaller), actual station
  location, low power stations that are not
  coordinated
• We need to protect actual station operations

12
13
Canadian TV Station Data

• NEW PLAN
• Canadians have a database of actual station
  operations this database is updated daily
• FCC will extract records for stations to be
  protected and make these records available for
  downloading on a daily basis
• OK to use CDBS until new Canadian database is
  available
• The new Canadian database download facility will
  be available soon and will be accessible from the
  OET TV white space webpage

U.S. Coastal Boundary

• Need to define the border areas of the United
  States coastlines for channel calculations
• Three zones
• Territorial Sea (12 nm)
• Contiguous Zone (24 nm)
• Exclusive Economic Zone (200 nm)
• TVWS database systems are to use the Territorial
  Sea limit
• Geospatial data defining the Territorial Sea is
  at www.nauticalcharts.noaa.gov/csdl/mbound.htm
• Land boundaries expected to be available for
  Canada and Mexico at end of December

LPTV/TV Translator Receive Site Update Facility

• OET and MB are setting up a facility for input of
  receive channel and site changes for TV
  translator, low power TV and Class A TV stations
• Update data will be included in the daily CDBS
  zipped file (table name to be provided later)
• OET will issue a public notice announcing the
  availability of the receive channel and site
  update facility when it is completed
• Not expected to require any separate
  implementation by database administrators

16
ULS Extraction Logic

• Information on how to download PLMRS records was
  provided at Workshop 3 (see consolidated
  presentations)
• Other ULS records to be downloaded include BAS
  point-to-point facilities, common carrier land
  mobile, paging and unlicensed wireless microphone
  registrations
• OET is preparing a standardized Extraction Logic
  for downloading ULS records (similar in function
  to the Extraction Logic for CDBS records)
• This will help to ensure that all databases
  download the same records
• The ULS Extraction Logic will be available soon

80 km Receive Site Waiver Requests

• Rules limit protection of TV translator, LPTV
  and MVPD receive sites to locations within 80 km
  of the received stations contour
• 24 parties filed requests for a waiver
• - 17 requested registration of translator
  receive sites, specifying a total of 120
  sites.
• - 7 requested registration of cable headends,
  specifying 48 sites and 163 received
  stations.
• We have reduced this list through preliminary
  analysis
• FCC will issue a public notice requesting
  comment on the remaining requests and then issue
  decisions.

18
Database Implementation Issues

• Fixed device registrations
• By the device alone as part of the initial
  database contact or
• By separate registration of the device by the
  responsible party
• In either case the device must provide the
  database its geological coordinates
• FCC enforcement/disabling requests
• Will be by direct request (letter) from the
  Chief, OET
• Action to be implemented by the database
  administrator(s)
• No special facility for FCC to effect disablement
  of devices EAS authorization may not change

19
Database Approval Process

• OET has issued two papers describing the
  approval process and the examination/tests that
  will be performed
• Database System Approval Process
• Database System Tests
• OET has also issued a checklist for tracking
  a systems progress through the approval
  process

20
Database Approval ProcessChecklist

• Checklist identifies the major milestones in
  the approval process
• Full approval occurs when all of the milestones
  have been satisfied
• Questions on the checklist?

21
Database Approval Process

• To begin the approval process, database
  administrators should send a letter of request
  to the Chief, OET (and cc senior staff)
• OET will then set up a meeting with the
  database administrator to discuss submission of
  materials and access to test the databases
  capabilities

22
Database Approval Process

• Database system tests include the database to
  TV band device interface
• An operational TV band device or emulator must be
  submitted to the Commission for interface testing
• OET has published a revision of KDB 416721
  White Space Test Procedures D02, which
  includes the database to device interface test
  procedures

23
Petitions for Reconsideration

• 5 Petitions for Reconsiderations outstanding
• In addition, there are a number of
  clarifications and clean-up of errors to be
  made
• We are aiming to have an MOO addressing these
  issues in the next couple of months
