  • 5G Deployment And Radio Altimeters - A Clash Of Industries And Regulato

    From Bill Horne@21:1/5 to All on Wed Jan 19 01:36:15 2022
    by Levine, Blaszak, Block & Boothby, LLP

    There is a fascinating dispute unfolding between the wireless
    communications industry and the aviation industry, or rather, a
    dispute between their respective regulators, the Federal
    Communications Commission (FCC) and the Federal Aviation
    Administration (FAA). The dispute revolves around the wireless
    carriers' use of C-Band spectrum to deliver 5G and the aviation
    industry's use of nearby spectrum to control aircraft.

    Listen to this 12-minute podcast as Steve Rosen, a Partner at LB3,
    David Lee, TC2's Technology Director, and Joe Schmidt explain this
    technical and legal conundrum and why it will be a regulatory and
    economic train wreck if the dispute doesn't get sorted.

    A good presentation of the details, most of which have not been adequately reported in the popular or even the technical press:

    Ok, I see the issue.

    My question is why did they wait until 5G is about to be deployed
    rather than speaking up well before now?

    Because neither the FAA nor the FCC have many technical experts left. So
    it takes a long, long time for technical issues to trickle up from the few technical people through all the lawyers up to the top.

    European countries dealt with this quickly and efficiently.

    And the honest truth is that for modern radar altimeters this isn't a
    problem. But there are plenty of planes out there flying whose radar
    altimeter receiver is just a horn and a diode detector. They were designed that way because there wasn't any use of adjacent bands so nobody bothered putting money and effort into making them any better.
