Identical to Distant ID the FAA haven’t managed to get any RF specialists within the room when contemplating the implications of one thing new. Distant ID has an issue with the z-axis for the operator’s place, it’s not correct sufficient for the FAA and can’t be except your smartphone or pill has a significant GPS replace.
Now the implications of 5G on actually dated manned plane gear is making an attempt to be mitigated by asking two of the businesses rolling out the service to please decelerate.
Manned aviation is totally hamstrung by historical gear and politically linked distributors of that gear.
The cellphone firms advised the FAA they gave them an opportunity to kind it out already and now they actually assume plane not outfitted with the correct gear, mustn’t use some airports, exclusion zones for them to be enforced.
The drone business isn’t any stranger to FAA foolery, let me pull one of the best bit out IMHO, it’s nicely down this web page.
Nonetheless, the FCC inspired the aviation neighborhood to make use of the almost two years earlier than C-Band deployment to improve any altimeters which may not be correctly designed to filter out frequencies far faraway from the 4.2-4.4 GHz altimeter band.
Inexplicably, the FAA and the aviation business apparently did nothing following the February 2020 order and even after the C-Band public sale closed in January 2021. The truth is, it was not till November 2, 2021 that the FAA even issued a discover to start gathering information about altimeters from the aviation business.
Who would have thought the FAA wouldn’t have saved to a deadline!
Operating the sky in 2022 prefer it was nonetheless 1982 not cuts the mustard.
What do we would like, a digital sky, when do we would like it, nicely as quickly because the FAA enters this millennium.
The bit the place the Authorities requested properly.

Pricey Mssrs. Stankey and Vestberg:
Thanks for the continued dialogue and on your prior settlement to an preliminary 30-day delay as we work to discover a resolution that can present confidence that 5G C-Band and aviation will safely coexist in the USA. We acknowledge the numerous funding your firms made to launch 5G C-band service, and the significance of increasing 5G service for the American financial system. On the similar time, absent additional motion, the financial stakes for the aviation business and the disruptions the travelling public would face from the industrial launch of C-Band service on January 5 are vital, notably with the continued stress and uncertainty brought on by the
coronavirus pandemic.
Accordingly, we search to construct on our productive discussions by providing the connected proposal as a near-term resolution for advancing the co-existence of 5G deployment in
the C-Band and secure flight operations. Failure to achieve an answer by January 5 will power the U.S. aviation sector to take steps to guard the protection of the touring public, notably during times of low visibility or inclement climate. These steps will end in widespread and unacceptable disruption as airplanes divert to different cities or flights are canceled, inflicting ripple results all through the U.S. air transportation system.
This proposal minimizes and spreads the short-term financial and operational burden whereas everlasting fixes are quickly put into place. It’s going to nonetheless contain vital disruptions for aviation operations within the U.S., however represents a significantly better approach ahead than the present trajectory.
Underneath this framework, industrial C-band service would start as deliberate in January with sure exceptions round precedence airports. The FAA and the aviation business will establish precedence airports the place a buffer zone would allow aviation operations to proceed safely whereas the FAA completes its assessments of the interference potential round these airports.
Our purpose would then be to establish mitigations for all precedence airports that can allow the vast majority of massive industrial plane to function safely in all situations. This may permit for 5G C-band to deploy round these precedence airports on a rolling foundation, such that C-Band deliberate places shall be activated by the top of March 2022, barring unexpected technical challenges or new security considerations.
In the meantime, the FAA will safely expedite the approvals of Alternate Technique of Compliance (AMOCs) for operators with high-performing radio altimeters to function at these airports.
We admire that this proposal gives a normal framework and that additional dialogue shall be wanted to make clear essential particulars. We decide to basing these discussions on the substantial technical data that has been shared and shall be shared as a part of this course of, to make sure that selections and outcomes are fact-based and data-driven.
As a part of this proposal, we ask that your firms proceed to pause introducing industrial C-Band service for an extra quick interval of not more than two weeks past the presently scheduled deployment date of January 5. Throughout this time, the FAA will establish the precedence airports, difficulty the required Notices to Air Missions (NOTAMs) and start approving AMOCs.
Throughout this time, the FAA will overview data referring to the dimensions of the buffer zone round vital airports and can search to scale back the dimensions when safely ready based mostly on information from aviation producers. The FAA will make each effort to finish this work as expeditiously as potential.
From the start of our discussions, our overarching purpose has been to guard flight security, whereas making certain that 5G deployment and aviation operations can co-exist. We consider this proposal advances this purpose and avoids substantial disruptions to aviation operations – and to the flying public – within the quick time period.
America has the most secure aviation system on the planet. We obtain this day-after-day by actively figuring out dangers and eliminating them. Passengers have faith that after they board one of many each day 45,000 industrial flights they are going to safely attain their vacation spot.
We’re an aviation nation as a result of flying is secure. Our secure aviation programs and thriving aviation business are profoundly essential to America’s financial system and our lifestyle. We all know you share the need to maintain aviation secure and environment friendly, and we urge you to significantly take into account this resolution as a common sense approach ahead.

The response….
Pricey Secretary Buttigieg and Administrator Dickson:
We’re writing in response to your letter despatched to us the night of December 31 concerning C-Band spectrum.
As you realize, the U.S. Authorities’s public sale of the C-band spectrum virtually a yr in the past was heralded by this Administration as a significant coverage victory and some of the profitable auctions ever carried out in the USA. From a monetary perspective, the public sale raised greater than $80 billion for the U.S. Treasury. Furthermore, the U.S. Authorities had decided that the USA was “lagging behind China” and different international locations in 5G deployment and {that a} main trigger for this was “the dearth of some carriers’ entry to the radio frequencies greatest fitted to 5G protection.”
The C-Band spectrum public sale was important in addressing this nationwide safety vulnerability and was needed to offer the connectivity for hundreds of thousands of American households and companies to work, study, and run their lives and companies. With continued COVID crises, it has by no means been extra essential that our nation’s vital communications infrastructure have the spectrum wanted to deal with escalating site visitors calls for from our prospects.
The public sale of the C-Band spectrum was the end result of years of research by the Federal Communications Fee, which is the skilled company of the U.S. Authorities on spectrum.
Amongst different issues, the FCC carried out an in depth public rulemaking course of by which submissions from lots of of events, together with from the aviation business, had been thought-about. On the finish of that course of in February 2020, the FCC adopted its prolonged and complete CBand Order, which discovered, amongst different issues, that its guidelines would absolutely “defend aeronautical companies within the 4.2-4.4 GHz band.”
The FCC had compelling causes for this conclusion. Spectrum interference disputes
usually contain simultaneous transmissions on the identical frequencies. However radio altimeters don’t function on, or wherever close to, the C-Band frequencies. Somewhat, they function in a frequency band (4.2-4.4 GHz) that’s separated by at the least 400 megahertz from the C-Band frequencies (3.7-3.8 MHz) that AT&T and Verizon will start utilizing in 2022 and at the least 220 megahertz from any C-Band frequency licensed to be used sooner or later. This helps clarify why C-Band 5G service and aviation operations already coexist in almost 40 different international locations the place C-Band
spectrum has been deployed with none adverse affect on aviation.
We care deeply concerning the security of our prospects, staff, and households, all of whom fly domestically and internationally for enterprise and pleasure. Our two firms are deeply dedicated to public security and nationwide safety, and thankfully, the query of whether or not 5G operations can safely coexist with aviation has lengthy been settled.
Counting on the FCC’s complete rulemaking course of and the C-Band Order, AT&T,
Verizon, and others bid greater than $80 billion on C-Band spectrum. With the FCC’s
encouragement, we then paid billions of {dollars} extra to speed up the migration of the satellite tv for pc firms that had been utilizing these frequencies particularly in order that we may start utilizing the spectrum in some geographic areas by December 5, 2021.
AT&T and Verizon spent most of 2021 making ready to place the C-Band spectrum into
service. Along with the tens of billions of {dollars} we paid to the U.S. Authorities for the spectrum and the extra billions of {dollars} we paid to the satellite tv for pc firms to allow the December 2021 availability of the spectrum, now we have paid billions of {dollars} extra to buy the mandatory gear and lease house on towers. Hundreds of our staff have labored continuous for months to organize our networks to make the most of this spectrum. Hundreds extra have been educated to have interaction with prospects as the brand new spectrum is put to make use of.
Amid all this exercise, we had been advised for the primary time late final yr that the Federal
Aviation Administration (FAA) and elements of the aviation neighborhood had considerations concerning the timing of our use of C-Band below the FCC’s February 2020 order. The aviation neighborhood participated within the C-Band continuing, and the FCC thought-about all their enter and located that the usage of the spectrum would trigger no dangerous interference to altimeters.
Nonetheless, the FCC inspired the aviation neighborhood to make use of the almost two years earlier than C-Band deployment to improve any altimeters which may not be correctly designed to filter out frequencies far faraway from the 4.2-4.4 GHz altimeter band. Inexplicably, the FAA and the aviation business apparently did nothing following the February 2020 order and even after the C-Band public sale closed in January 2021. The truth is, it was not till November 2, 2021 that the FAA even issued a discover to start gathering information about altimeters from the aviation business.
Because of this inaction, the U.S. Authorities approached AT&T and Verizon in
November to ask us to delay utilizing the C-Band spectrum with the intention to keep away from potential disruption to the aviation business, which had been in its personal energy to keep away from. Regardless of the 1000’s of people that had been working for nearly a yr in direction of a December 5 C-Band deployment, regardless of the billions of {dollars} of capital now we have invested in our networks in 2021 to organize for C-Band, and regardless of the $80 billion that the wi-fi business paid final yr to be used of the C-Band spectrum, AT&T and Verizon agreed to attend till January 5, 2022 to start utilizing the C-Band and to
implement further restrictions on our use of the spectrum by July 5, 2022, over and above the operational restrictions the FCC already had discovered enough to guard radio altimeters.
Though there was no requirement for us to undertake these measures, we did so
voluntarily within the spirit of cooperation and good religion. Now, on the night of New Yr’s Eve, simply 5 days earlier than the C-Band spectrum shall be deployed, we obtained your letter asking us to take nonetheless extra voluntary steps – to the detriment of our hundreds of thousands of shopper, enterprise and authorities prospects – to as soon as once more help
the aviation business and the FAA after failing to resolve points in that expensive 30-day delay interval, which we by no means thought-about to be an preliminary one.
As you realize, the FCC is the skilled company designated by our authorities to make
selections governing the usage of our nation’s scarce spectrum assets. Its potential to set and administer coverage has been rightfully revered and thoroughly adopted by policymakers across the globe. Its job is a tough one – to not serve the pursuits of anybody business or stakeholder, however to make sure that finite spectrum assets are deployed intelligently in opposition to a cautious steadiness of industries (e.g., communication, satellite tv for pc, aviation, automotive, shopper electronics, protection) and in consideration of innovation and financial growth, public curiosity, and the safety
of the pursuits of the USA.
At its core, your proposed framework asks that we conform to switch oversight of our
firms’ multi-billion greenback funding in 50 unnamed metropolitan areas representing the lion’s share of the U.S. inhabitants to the FAA for an undetermined variety of months or years.
Even worse, the proposal is directed to solely two firms, whatever the phrases of licenses auctioned and granted, and to the exception of each different firm and business throughout the purview of the FCC.
Agreeing to your proposal wouldn’t solely be an unprecedented and unwarranted circumvention of the due course of and checks and balances rigorously crafted within the construction of our democracy, however an irresponsible abdication of the working management required to deploy world-class and globally aggressive communications networks which are each bit as important to our nation’s financial vitality, public security and nationwide pursuits because the airline business. We’re, nevertheless, dedicated to proceed our cooperation together with your Division and all events, together with the provide of additional mitigations described beneath, on the situation that the FAA and the aviation business are dedicated to doing the identical with out escalating their grievances, unfounded as they’re, in different venues.
On December 31, we filed with the FCC once more reiterating that we’ll abide by the
appreciable mitigation measures we introduced in November and that we’re voluntarily implementing for six months as your Division and the aviation business take no matter steps you assume applicable to make sure that all plane are correctly outfitted. These are voluntary steps we’re taking, over and above what’s required by our FCC licenses, within the spirit of cooperation.
In your comfort, we’re attaching a duplicate of the December 31 submitting to this letter.
As well as, regardless of the extraordinary and unprecedented nature of your additional request, we are going to once more volunteer, within the spirit of cooperation and good religion, to change our use of the C-Band spectrum throughout the identical six-month interval (except we and the FAA decide that these voluntary limits needs to be relaxed sooner).
Particularly, for six months, till July 5, 2022, we are going to undertake the identical C-Band radio exclusion zones which are already in use in France, with slight adaptation to replicate the modest technical variations in how C-band is being deployed within the two international locations. That strategy – which is without doubt one of the most conservative on the planet – would come with in depth exclusion zones across the runways at sure airports. The impact can be to additional cut back C-band sign ranges by at the least 10 instances on the runway or over the last mile of ultimate strategy and the primary mile after takeoff. That is over and above the protections we already dedicated to place in place round airports that had been detailed within the letter to the FCC on November twenty fourth, 2021 – protections that the FCC known as amongst “probably the most complete efforts on the planet to safeguard aviation applied sciences.” As you realize, U.S. plane presently fly out and in of France day-after-day with 1000’s of U.S. passengers and with the total approval of the FAA. Because of this, France gives a real-world instance of an working atmosphere the place
5G and aviation security already co-exist. The legal guidelines of physics are the identical in the USA and France.
If U.S. airways are permitted to function flights day-after-day in France, then the identical
working situations ought to permit them to take action in the USA, as we suggest within the technical particulars connected to this letter.
These further voluntary measures will give the FAA and the aviation business ample alternative to conduct any additional research and remediate any altimeters which may not meet present requirements, as was initially really useful by the FCC in February 2020. We belief they’re enough to allay any remaining considerations expressed in your December 31 letter.
