FCC Opens More Spectrum for WISPs 98

flirzan writes "Today the FCC announced that they will be opening up new spectrum for use in wireless broadband applications. The new spectrum will run from 3650-3700 Mhz, and requires that licensees register all system base stations. This is great news for wireless ISPs everywhere, as it will make interference avoidance/mitigation much easier. Licenses will run 10 years, and are renewable and transferable. No word yet on how much the licenses are expected to cost or when they'll be available."

      FCC OPENS ACCESS TO NEW SPECTRUM FOR
      WIRELESS BROADBAND IN THE 3650 MHZ BAND

      WASHINGTON, D.C. - Today, the Federal Communications Commission (FCC or
      Commission) adopted rules to open access to new spectrum for wireless broadband in the 3650-3700
      MHz band (3650 MHz). The Commission adopted a hybrid approach that draws from both the
      Commission's unlicensed and licensed regulatory models and provides for nationwide, non-exclusive
      licensing of terrestrial operations in the band utilizing technologies employing contention-based
      protocols. This streamlined licensing mechanism with minimal regulatory entry requirements will
      encourage multiple new entrants and stimulate the rapid expansion of wireless broadband services --
      especially in rural America -- by Wireless Internet Service Providers (WISPs) and other entities with
      limited resources. The Commission also provided an opportunity for the introduction at 3650 MHz of a
      variety of new wireless broadband technologies, such as Wi-Max, into the band.

      Under the Commission's approach, there is no limit on the number of licenses that can be
      granted, and each licensee will be authorized to operate on a shared basis with other licensees on all 50
      megahertz of the band, subject to restrictions in geographic areas occupied by grandfathered Fixed
      Satellite Service (FSS) and Federal Government stations. Licensees will also be required to register all
      system base stations electronically with the Commission. Base station registration will enable licensees
      to locate each other's operations and will facilitate protection of grandfathered stations from interference.
      This type of licensing and registration will enable the Commission to monitor the use of this spectrum as
      new technologies and services develop.

      The Commission found that the public record developed in this proceeding supports multiple
      users sharing this spectrum through the use of "contention-based" protocols to minimize interference
      among fixed and mobile operations. New fixed and mobile stations will therefore be required to use
      contention-based protocols, which will reduce the possibility of interference from co-frequency operation
      by managing each station's access to spectrum. The Commission concluded that this approach is a
      reasonable, cost-effective method for ensuring that multiple users can access the spectrum.

      The Commission gave all licensees the mutual obligation to cooperate and avoid harmful
      interference to one another. Mobile stations also will be required to positively receive and decode an
      enabling signal transmitted by a base station. The Commission determined that this approach will ensure
      that mobile stations operate within range of registered base stations, thereby avoiding interference to grandfathered FSS and Federal Government stations. Fixed stations will be allowed to operate with a
      peak power limit of 25 Watts per 25 megahertz bandwidth, and mobile stations with a peak power limit of
      1 Watt per 25 megahertz bandwidth.

      The Commission kept the existing allocations for the band, grandfathering previously licensed
      primary incumbent FSS earth station operations and three Federal Government radiolocation stations,
      entitling them to interference protection from new wireless licensees. To protect these incumbent
      operations, the Commission established circular protection zones around them - 150 km for FSS earth
      stations and 80 km for Federal Government stations - and prohibited new terrestrial licensees from
      operating within these zones unless they negotiate agreements with the incumbents. The Commission
      determined that new FSS stations should be allowed on a secondary basis and denied several petitions for
      reconsideration of an earlier decision in this proceeding that established the existing FSS, FS and MS
      allocations.

      The Commission also concluded that there should be no eligibility restrictions

      There is another factor. FCC regulations require that licensees actually use their licenses. Once a license is awarded, the licensee must construct facilities within a certain time and begin service within a certain time after that - in total, about 2 years.

      For the upper bands, the local governments have quite a bit of say in how thigns are alloted due to the fact that those signals just don't go very far beyond line of sight under normal circumstances. There are some exceptions that are dictated by the ITU and the US pays attention to those. These exceptions are mostly for research quiet zones (and those are pretty small), non geo-sync sats, etc.

      The HF bands (which readily propagate around the world), VHF and lower UHF (which can propagate distances significantly beyond those you would expect) have some ITU regulations attached to them. The FCC does pay attention to these international regulations of the RF spectrum.

      The US also has agreements regarding allocations up in the microwave ranges along its borders with other nations to avoid interference.

    The FCC regulates the Broadband Radio Services (BRS). This is (now) typically broadband internet access, and happens in from 2.495 GHz to 2.690 GHz, and uses spectrum formerly set aside for (oxymoron alert) wireless cable TV. You, too can get a license in this band for a $230 filing fee, today.

    There is another band, 3.400 GHz to 3.600 GHz that's also currently set up for licensed wireless data, a la wi-fi. I don't have a link to this service unfortunately.

    What the new announcement from the FCC adds to the party is something similar to GMRS or business band radios-- shared spectrum open only to licensed users. TFA mentions Part 90 as the section of rules that will cover this new spectrum. That's the same section of rules that covers business band radios (and whose licenses cost $100-ish). I would also expect frequency coordination to come into play at some point with this new service, just like you have with other Part 90 services. (Coordination tries to prevent harmful interference and squabbling.)

Licenses were usually on a per-transmitter basis, but some were on a geographic-area basis (BTA, if I recall).
