It’s laborious to say the talk over the 12 GHz band is heating up, given it’s already been the topic of high-level jabs from SpaceX, Dish Community and others at loggerheads over how the spectrum must be used. But when a latest Zoom occasion is any indication, the talk is certainly ratcheting up.
Perhaps it has one thing to do with the $81 billion the C-band public sale raised. The 12 GHz band, as soon as thought of excessive on the mobile spectrum charts, is now being described as among the finest positioned mid-band spectrum bands probably out there for 5G. Granted, the C-band concerned decrease spectrum, within the three.7 GHz band, however that was solely 280 megahertz up for public sale. The 12 GHz band represents an opportunity to convey a full 500-megahertz contiguous spectrum band to marketplace for 5G.
The FCBA Basis hosted a Zoom assembly on Thursday that included representatives from AT&T, Dish Community, RS Entry and OneWeb, the place panelists clashed over whether or not it’s potential for the band to be shared between satellite tv for pc and terrestrial customers. The FCC in January voted to difficulty a Discover of Proposed Rulemaking (NPRM) on the 12 GHz band, exploring whether or not guidelines could also be modified to accommodate 5G companies.

Dish is among the authentic members behind the 2016 MVDDS 5G Coalition petition that requested the fee to contemplate new makes use of for the band and it’s supportive of the FCC’s NPRM. It is among the predominant customers of the 12 GHz band for its direct broadcast satellite tv for pc (DBS) providing that serves thousands and thousands of satellite tv for pc TV subscribers who use it to observe video.
Dish additionally holds the best variety of MVDDS licenses; it has 82 licenses. That offers Dish a singular perspective on the potential for sharing the band and utilizing it to assist 5G. “Dish believes there’s a path ahead for sharing between DBS and terrestrial, versatile use,” stated Alison Minea, senior counsel at Dish. “That is 500 megahertz of contiguous spectrum that’s much better by way of propagation” than another spectrum allotted for 5G.
Dish’s hope, on the finish of this, is the FCC can discover a technique to permit two-way, terrestrial versatile operations within the 12 GHz band whereas defending DBS. “We imagine that this can be a win-win end result,” she stated.
Different spectrum for NGSOs?
As for the satellite tv for pc operators which can be at the moment utilizing the band for trials and demos, she stated Dish needs to see them achieve success and urged there are different spectrum assets they will use.
“I might like to know what different band you assume we may use,” stated Ruth Pritchard-Kelly, senior advisor at OneWeb. “That is among the largest questions that the satellite tv for pc trade has.”
OneWeb’s low earth orbit (LEO) technique requires offering final mile connectivity for cellular community operators to ensure they will join everybody and that connection doesn’t should be carried out solely with a terrestrial community, she stated.

The satellite tv for pc companies are being ready. “We’ve already began demos and trials,” she stated, and by the tip of 2022, your entire globe will likely be coated by SpaceX and OneWeb constellations. “I really like engineers. They’re superb. I do hope they work out a technique to share the spectrum, however because it stands now, actually our opening place is you may’t share with a ubiquitous factor that’s transferring.”
Oh, sure you may share
RS Entry holds 82 licenses within the MVDDS band; its frequency covers about 25% of the U.S. geography and about 16% of the U.S. inhabitants.
“This can be a very distinctive useful resource,” stated V. Noah Campbell, founder and CEO of RS Entry. “It’s an enormous quantity of spectrum… It’s pretty flippantly used.”
RS Entry isn’t towards non-geostationary orbit (NGSO) companies, corresponding to SpaceX’s Starlink, Amazon, or OneWeb. They may play a important position in bridging the digital divide, he added.
Because of the NPRM, RS Entry is engaged in an intensive engineering evaluation and its preliminary evaluation exhibits sharing is possible right here. “I believe we’ve got artistic options,” he stated. The NPRM was introduced on January 15, when the preliminary stage of the C-band public sale closed with proceeds over $80 billion, and “there’s clearly an enormous quantity of demand… for mid-band spectrum.” The 12 GHz band is “very very like mid-band spectrum.”
RS Entry has identified that each SpaceX and OneWeb had been placed on discover after they acquired authorization to make use of the spectrum that it could possibly be used for one thing else sooner or later. “The Fee has repeatedly warned SpaceX and different NGSO FSS authorization recipients that it was contemplating the initiation of an NPRM on precisely this difficulty,” RS Entry informed the FCC final November. “Neither SpaceX nor OneWeb can declare to be stunned that the Fee may provoke an NPRM on this matter.”
Present state of utilization
As for the present customers of the spectrum, “that is our bread and butter,” Minea stated. “That is how Dish started,” offering satellite tv for pc TV. DBS is a enterprise that it hopes to develop over time, she stated, regardless that it’s at the moment shedding subscribers.
“Our engineering research point out there’s a very viable plan for DBS to share with terrestrial versatile use,” she stated. Engineering coordination measures will likely be required, however “all of that is doable.”
DirecTV is the largest consumer of the band, and it makes use of your entire 500 MHz to assist its subscribers, in accordance with Raquel Noriega, director, Federal Regulatory at AT&T. “We actually don’t see an engineering path ahead right here” for sharing, she stated.
(AT&T final month introduced a cope with TPG Capital to promote a minority stake in its linear video companies DirecTV, U-verse and AT&T TV. The brand new DirecTV firm will likely be run by Invoice Morrow, who as soon as led Clearwire.)
Pritchard-Kelly stated one of many issues about satellites is “we are able to’t simply change from Ku to Ka.” The satellite tv for pc is within the sky for its lifetime, which could be 15 to 20 years. That is the sort of dialogue that should go on for years to offer engineers time to find different bands, she added. “This can be a extremely used band for a service that presently, has no different.”
Customers and potential customers of the 12 GHz band may have an opportunity to inform the FCC what they assume must be carried out. Preliminary feedback within the NPRM are anticipated to be filed by April 7, with reply feedback due Could 7.
