Frequency Coordination Process

10/6/2011Super Bowl Frequency

Coordination 2

Super Bowl XLVIFrequency Coordination Goals

Act as a central clearinghouse of frequencies and requests

Maximize the number of users that can successfully operate in a limited area

Identify and help resolve conflicts


Coordination 3

Super Bowl XLVIFrequency Coordination Challenges


Coordination 4



Coordination 5

Frequency CoordinationWhat do we coordinate?

Almost everything in the city during the week of the event held at NFL Venues• Fixed and portable microwave links• Low Power devices:

including wireless mics, intercoms, IFBs• RPU: 2-ways, high power IFBs• Wireless LANs; 802.11a/b/g• Nextel and Cellular: COWS

Need contact info but not necessarily frequencies• Public Safety Radios –

Tag undercover users, voting receivers and high power bases/repeaters near stadium

• business band radios


Coordination 6

Frequency CoordinationWhat do we NOT coordinate?

Family and General Mobile Radio Service radios• New ‘CB’ radio service• Use at your own risk!

Amateur Radio Cellular/Nextel type portable radios Public Safety radios –

• Includes anyone in uniform and with public safety credentials

10/6/2011 Super Bowl Frequency Coordination 7

Super Bowl XLVFrequency Coordination

Active Media Day (Tuesday), Game Day (Sunday) at Stadium and all week at Media Hotel & NFLX• We realize that Media Day is more of a news event vs.

game day is a production event • impacts scheduling of users equipment

1st Come, 1st Served with frequencies• BUT - we can't protect what we don't know about• If close to venue, get frequency list for fixed equipment

(intercoms, studio mics, IFBs, etc) in NOW• Request what you need…

But remember "Frequency Karma" • request only what you really need


Coordination 8

Frequency CoordinationThe Coordination process

We start with base database • Input from local SBE Coordinator and GDC • Add local FCC licensed BAS frequencies

Add local microwave home channel plan

Individual databases for Venues/Events• NFL Media Center• Super Bowl Media Day• Super Bowl Game

Post Game Only

Database ConstructionVHF/UHF Communications

Initial database is based on FCC licenses• Questionable accuracy – Need to verify:

Users Stations license more than they use How is this devices used When is it typically used Home channel plan? Frequencies Bandwidth Fixed TX Sites (Repeaters, Bases) RX only sites

Database ConstructionUser Requests


Coordination 10

Submit your needs• List equipment you have to fill those needs• e-mail needs and available frequencies to us

Identify nearby sites/facilities to protect• Need Address or Latitude/Longitude

Studios RX sites –

• ENG: 2/6.5/7/13 GHz• VHF/UHF “voting sites”

Database ConstructionLocal Fixed Sites

List of frequencies in use at critical fixed sites• Wireless mics• IFBs• Intercoms• Etc.


Coordination

Database ConstructionENG Microwave

ENG microwave• What bands are in use

2/2.5 GHz – assumed to be digital modulation 6.5 GHz

• Analog vs. digital modulation• 8 vs. 25 MHz wide channel spacing

7 GHz 13 GHz

• Bandwidth used: 6, 7, 8, 10, 12, 20, 25 MHz• “Home” channel plan used?• Standardized offsets and/or polarities used?• Receive site locations


Coordination

Database ConstructionENG – Wireless Mics & IFBs

List ALL devices you have available• Identify fixed frequency transmitters• Identify critical users and frequencies• List frequency agile devices by

Name or truck the device is assigned tomake model frequency band/block it can tune toCustom frequency charts; if applicable


Coordination

Specify the facilities required when & where they are needed

Database ConstructionGather and Submit Key Contacts

Key Contacts include• Engineering• News Operations• ENG Control Points• Super Bowl Coordinators

Required contact information• Names• Title• Phone number(s)

include after hours number• E-mail address


Coordination

Database ConstructionRequest Processing


Coordination 16

We enter frequencies into database• Identify conflicts and help resolve them • You receive a confirmation e-mail listing frequencies we

have added to database• Process Requests and Confirm Frequencies

Initially, you will NOT get all devices approved at all venues.• Have to be fair to all users• Identify hardware carried by critical users• Identify hardware needed at a specific events/venues

Operations may be restricted to Places, Dates and Times

Super Bowl Frequency Coordination Zones

Coordination

Time and Date based Coordination


Coordination

Licensed users have priority


Coordination

Frequency requests are considered on Necessity vs. Convenience Basis


Coordination

Fixed locations and stand-ups should be wired


Coordination

Camera audio links will be approved only for safety and NOT convenience

RF Best Practices Use Minimum power necessary to operate Install Isolators/Circulators on

transmitters if possible Location of receive sites

• ENG RO Sites• VHF/UHF “voting” receivers

Plan, Communicate & Execute the Plan

Maximum occupied bandwidth is 150 KHz for wideband devices


Coordination

Wideband Intercom Beltpack/Frequency Ratio is 3:1

KV3

KV3 This shows a "Notch Type" duplexer which is NOT recommended. Using one of these will limit the ERP of the TX to 2 watts.

The recommended Duplexer, a "Bandpass Duplexer" is similar except the filters ONLY PASS THE DESIRED RX OR TX FREQUENCIES

Should also show an ISOLATOR to the TXKarl Voss, 4/1/2010

Auditing of Frequency Usage & System Configuration


Coordination


Coordination 35

Frequency CoordinationWhat to expect on Media Day and Game Day

What to expect on Media Day and Game Day The check-in process:

• pre-coordinated vs. non-coordinated lines• mandatory frequency and transmitter check • frequency selection (if necessary)• Bringing a copy of the coordination notice will speed up

check in process Radio tagging:

• No RF• POST GAME ONLY• OK to use

Please, bring ONLY the frequencies and radios you have been confirmed to use on Media and Game days!


Coordination 36

Frequency Coordination“RF War Games”

The Ultimate RF test for everyone!• Planning becomes useless with poor

installation practices• Used to identify and solve problems

such as intermod• Planned for Thursday, 2/2 at 12:30p• Possibly another on Saturday -

depending on the earlier test


Coordination 37

Frequency CoordinationOther things to be aware of

STA has been applied for TV channels 18 & 20? (494-500 and 506-512 MHz)• LOCAL WIRELESS MICS, IFBS or INTERCOMS in these

bands?

700 MHz operations• No Part 74 use of these frequencies anymore• Don’t try to request or use a frequency above 698 MHz

Wireless LANS (802.11 b/g) TV Pickup and Public Safety in 2.5 GHz• All WLAN Access Points MUST be turned OFF

or coordinated before use


Coordination 38

Frequency CoordinationOther things to be aware of

Superbowl Coordination offices:• Main Offices: Lucas Oil Stadium

Inside secure perimeter – Outside Stadium South Gate Any Superbowl credential allows access Opens Sunday 1/29 and closes after game
