Just a few weeks again, each Verizon and AT&T introduced they’d be pausing some points of their 5G deployments over FAA issues that these deployments would create important security hazards. The drawback: there’s completely no proof that these security issues are professional.

The FAA and airline trade declare that use of the three.7 to three.98 GHz “C-Band” spectrum to deploy 5G wi-fi creates interference for avionics tools (particularly radio altimeters). But the FCC has carefully examined the claims and located no proof of precise hurt wherever on the earth, the place greater than 40 international locations have deployed C-band spectrum for 5G use. Just to make certain, the FCC put aside a 220 MHz guard band that can stay unused as a form of buffer to forestall this theoretical interference (double the quantity Boeing requested).

None of this was sufficient for the FAA. That’s of main annoyance to AT&T and Verizon, which paid $45.45 billion and $23.41 billion respectively earlier this yr for C-band spectrum, and have been extensively and justifiably critcized for underwhelming 5G community efficiency and availability thus far. Consumer advocates and coverage consultants like Harold Feld are additionally confused as to why the FAA continues to dam deployment in these bands regardless of no proof of precise hurt:

“…the technical evidence on which the FAA bases its interference concerns have a lot of problems — not least of which that about 40 other countries operate similar 5G deployments in the same C-Band without any interference showing up. Either physics works differently in the U.S., or the report at the center of this controversy needs to explain why this hasn’t shown up in any other country where deployments are either authorized or have already taken place.”

Not solely did the FAA block the deployment of 5G within the C-band based mostly on what seems to be nonexistent proof of hurt, Feld means that whereas the FAA has been leaking their issues to the Wall Street Journal, they’ve concurrently refused handy over wanted information to the FCC (you realize, the company that truly has experience in wi-fi spectrum deployment and use).

As Jon Brodkin at Ars Technica notes, the FAA’s personal November 2 bulletin (pdf) states there is no “proven reports of harmful interference” with C-Band 5G deployments wherever on the earth. As Feld notes, all the fracas (which started through the Trump period and continues till now) must be remedied as soon as the FCC is lastly absolutely staffed:

“If nothing else, this exercise should make it abundantly clear why the Senate needs to confirm Davison, Rosenworcel and Sohn as quickly as possible. We cannot have spectrum disputes between agency fought out in the press in ways that destabilize confidence in the safety of air travel. Federal policy at this level is not a game of chicken, and cannot be fought out like this in the press. We need the key agencies here at full strength and able to resolve the systemic problem — not just the existing problem.”

In the interim, the dumb squabble will simply contribute to the present din of gibberish about how 5G is a well being and security hazard. Evidence of most of those claims stays fully elective.
