Unlicensed Wireless Microphone Venue

Registration SystemOriginal 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

8

Unlicensed Wireless Microphone Venue

Registration SystemNew 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

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

10

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 LocationsNEW:

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

12

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

13

Canadian TV Station Data

13

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

14

U.S. Coastal Boundary

1414

• 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

15

LPTV/TV Translator Receive Site Update Facility

1515

• 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

1616

• 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

17

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 system’s 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 database’s capabilities

222222

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 MO&O addressing these issues in the next couple of months

Other Issues and Questions
