More Experts Weigh In On Possibility 12 GHz Band Can Be Shared with 5G Services
More experts weight in on the debate about whether the 12 GHz band can coexist with 5G operations.
WASHINGTON, November 9, 2021 – Experts at the New America Open Technology Institute last week suggested that the 12 Gigahertz band can be shared with 5G wireless services and argued that the big-name proponent that says it can’t has allegedly not produced evidence saying otherwise.
The Federal Communications Commission, studying the sharing possibility, has fielded comments from Elon Musk’s SpaceX, which has argued that the 12 GHz band used by satellite services, cannot be shared with 5G wireless providers because of interference problems. On the other hand, providers like RS Access have argued that it can, using a technical study from RKF Engineering to demonstrate as such.
At a New America Open Technology Institute event on November 2, Kathleen Burke, policy counsel at internet advocacy group Public Knowledge, alleged SpaceX hasn’t submitted any studies showing it’s not possible to share spectrum.
Burke said SpaceX has no engineering analysis supporting its claim that the band could not be shared. “Incumbents are not open to sharing spectrum” she said, alleging a strong desire for SpaceX to win exclusive use licenses for its satellite venture.
“The evidence demonstrates it is possible to share this band,” she added.
Nicol Turner-Lee, director of the Center for Technology Innovation at the Brookings Institution, said that it’s worth looking at innovations in satellite. “When we come up with a solution for the digital divide, shared spectrum use [of the 12GHz band] has always been on the palate,” she said.
“The question is, can we get along when there’s so many people that are disconnected,” she added. “This may not be picking winners and losers and more about getting everyone on board…no one should hog the spectrum if it’s at the expense of communities that need it most.”
Mid-band crucial for 5G
Michael Calabrese, director of the Wireless Future Project at New America’s Open Technology Institute, said that the 500 megahertz of mid-band spectrum on the 12GHz band offers more speed and potential than any other mid-band spectrum being considered by the FCC. Using the 12Ghz band for 5G and authorizing the band for open shared access could “promote more competition, enhance the benefits of next-generation Wi-Fi, and help address the digital divide,” he said.
The RKF engineering study concluded that Starlink’s SpaceX low-earth orbit satellite terminals can reject 5G signals; technology used by mobile wireless networks will direct energy toward handsets, not satellite terminals; and 5G networks will largely be used in higher population areas while Starlink will target mostly rural areas.
