How does this affect new installations?

You can still install new devices under your WBS (Part 90Z WBS) licenses. They just don't get "incumbent" status, wherein you can register a big protection zone in the SAS, when CBRS comes along. The licenses mostly expire April 17, 2020, so if you're not using something that looks like it will become a CBSD, then keep that in mind when evaluating the purchase.

    How about towers that were installed previously?

    "Grandfathered Wireless Broadband Service" (3.65) licenses will
    remain in effect until 2020. If they expire before then, they can
    be renewed for up to that date. If they happened to be issued in
    the 2010-2013 time frame before the CBSD docket opened, then they
    get their full 10 years, which can make some of them run as late
    as March, 2023. For strange reasons I won't get into here, that
    can have unfortunate consequences, so there may be pressure on
    some WISPs to transition them anyway in 2020.

    Grandfathered devices fall into two categories. If you Registered
    them in ULS before 4/17/15 and had them in revenue service by
    4/17/16, then they become Incumbent in CBRS and are entitled to
    very strong protection against other CBRS devices, on their
    current frequencies. That can have a 17 km radius, IIRC. If they
    were not registered, they get protection to 5.4 km. You can still
    add devices, but they are not treated the same as the ones that
    were registered. So if you had registered a device on that tower,
    it gets good protection until 2020.

    Once the GWBS licenses expire, the device either has to be
    re-approved as a CBSD (some will, some won't) or go off the air.
    I'd expect the LTE and some WiMax and other current clean-signal
    devices to get CBSD upgrades and approval; I don't expect any
    Wi-Fi-derivative devices to do so. Just speculating, though.

            I've been off-line for a while.  What is the latest set
            of decisions from the FCC with the 3.65 band?


        A second Report and Order was issued in May, 2016. Since
        then, the action has moved to WinnForum, which is producing
        the standards for how to actually use the band. That includes
        protocols for how a CBRS Device (CBSD) will communicate with
        a Spectrum Authorization System (SAS) and how the several
        SASs will communicate with each other. WISPA is represented
        there by myself and Richard Bernhardt. As of now, the first
        release of the protocols has been published, basically to
        allow vendors to start development, and we're working on
        further versions that are actually practical. Some guesses
        are that equipment using CBRS may become available, with
        FCC-approved SAS service, sometime around the end of the year.
