Title: Some more spectrum repack docs...
Post by: Aram Piligian on January 02, 2018, 04:40:54 pm
Happy New Year! 

With the new year comes purchasing season, so I've been compiling some of the spectrum repack data for a variety of cities, in an effort to have answers to the whats, whens, and whys from management.  In this post you'll find a png (full quality PDF linked with other files) with an overview of the rollout phases for a few major market cities, as well as a link to a folder of Pete Erskine's Wireless Planner for each of those cities.  I've added some of the missing Shure gear as well, though newer offerings from other manufacturers are likely absent. 

Process (how'd I come up with these?)

-First, I used http://otadtv.com/tvtower/index.html (http://otadtv.com/tvtower/index.html) to find current TV stations in a 50mi radius of major city centers

-Next, I used this (https://www.law.cornell.edu/cfr/text/47/90.311) documentation from the FCC on public safety bands in major cities

-On the FCC's Incentive Auction Data Files (http://data.fcc.gov/download/incentive-auctions/Transition_Files/) site, I found the Tableau Reader file which gives a map view of stations that are changing during the repack.  I selected a 50mi radius of the major city centers and saved the resulting list of stations undergoing changes.

-Finally, I cross-referenced my initial results with the repack list, and made it look pretty.

Please let me know if you find any errors--digging up this stuff can be tedious and I'm sure there's mistakes and omissions.  These are living documents; I'd love to improve and maintain them going forward with the help and collaboration of others.

Cheers,
Aram

Thanks, Aram.  I posted a link to this thread over at Control Booth.

Cool! 

Following up on this, RF Venue asked me to write a guest blog post giving it some context.  It can be found here (https://www.rfvenue.com/blog/the-road-to-repack-broadcast-spectrum-transformation).

This is a repost of a terrific RF Venue article.  NOTE that in Dallas there is virtually no spectrum left.

In today's guest post from Aram Piligian of IMS Technology Services, the broadcast spectrum repack is covered in detail, with an important free download (https://www.rfvenue.com/blog/the-road-to-repack-broadcast-spectrum-transformation?utm_source=hs_email&utm_medium=email&utm_content=59870320&_hsenc=p2ANqtz-_39pRSL3Dv59tyDumfi9gryl-F5yLI-OjjS6W8RoCxTtRz-Yph2QD-Vh0ZRE4Wr48Q0ZuoUSMtw_FMrF6X0g9iLVyDWQ&_hsmi=59870320) and other resource links covering rollout phases in major metropolitan areas.

I highly recommend sharing this with your team so you can anticipate these important changes that will have a direct impact on your operations of wireless mics and IEMs going forward.

As always, if I can answer any questions or assist in your preparations for this transition just reply to this email.  There are a number of techniques and tools available including affordable spectrum analysis (https://www.rfvenue.com/software?utm_source=hs_email&utm_medium=email&utm_content=59870320&_hsenc=p2ANqtz-_39pRSL3Dv59tyDumfi9gryl-F5yLI-OjjS6W8RoCxTtRz-Yph2QD-Vh0ZRE4Wr48Q0ZuoUSMtw_FMrF6X0g9iLVyDWQ&_hsmi=59870320) and RF filtering that will be must-haves in the RF toolkit moving forward as more wireless devices compete for less spectrum.

Hey Pete, thanks for the kind words.  Working from your spectrum planner document got the ball rolling for this, so thanks for the inspiration!
