FCC Opens More Spectrum for WISPs

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 not a limit on the number of licenses. This is a break in the usual FCC trend of limiting the nubmer of licenses given based on the number of "channels" that can be defined. They are doing this because of the requirement that users of this new band utilize technologies that would allow automatic interference remediation and channel-sharing techniques. This is how the current 2.4GHz ISM band operates.

      The fact that this will be a licensed service allows for higher powers. Fixed stations are allowed 25W per 25MHz of bandwidth, and mobile stations are allowed 1W per 25MHz of bandwidth. (I like this method of power limits, because in today's world of wide-banded radio technologies, this effectively attempts to cap the signal intensity on any frequency slice rather than total output power.

      2. Are there limitations on the number of WISP licenses you may hold? That is to say, would it be possible for Clear Channel or SBC or subsidiaries of either to buy up all the WISP licenses for a certain area and then just sit on them, blocking any competition from entering the market?

      This question is essentially moot given that there is no limit on the number of licenses available in one geographic location and that frequencies will be shared.

      I look forward to seeing how this will pan out in the consumer-gear market. 2.4GHz has been totally trashed because of the near-ubiquity of 802.11 services; a product of the unlicensed nature of the ISM band -- everyone can dump a signal out! (how's that for a runon sentence?)

      If the equipment for operating in this band is kept out of the "mass retail" market, this will end up being a great thing. It's when you get a million or so average-joes who may be good to average network operators, but who don't understand squat about RF collision domains that things really start to get mucked up.

      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.

      If a licensee doesn't use the frequency or hasn't constructed, the license effectively comes up for grabs on a first come-first served basis. This is called a "finder's preference," where whoever rats out the non-performing licensee to the FCC gets first dibs on the license.

      As such, if someone were to buy a license and just sit on it, it would only last a short time - the license can be snatched out from underneath them.

      With any wireless system the spectrum is divided in a similar way. For example, in cellular phone systems there are chunks of bandwidth set aside for control channels, the base station to mobile link, and the mobile to base station link. Often times these chunks are all fairly close to each other (within the same general band).

      separating the frequency range for different applications is not necessarily a good idea - having the devices intelligently use the spectrum they see is a key issue. Also, the modulation scheme used for the data determines the bandwidth and can be changed to most efficiently ustilize the spectrum (different data rates for different links, e.g. assymetric DSL) and the channel conditions.

      As far as distance goes, the general idea is that lower frequencies propagate farther (AM radio has a longer range than FM partly because of the frequencies involved). The signal strength that you see as you move away from a transmitter does not drop linearly though (proportional to 1/d^2 for free space) which means that you lose a lot of power quite quickly. Of course sending out more power will let you go a little farther, but it also helps things like bluetooth since they can be low power devices (always a good idea) and won't interfere with things fairly close to them.

      Broadband Radio Service isn't what you think it is. Existing licenses were largely granted by lottery, before auctions were allowed, or later by auction. They were indeed called "wireless cable"; HBO was a big item back in the 1980s. A few video systems are still running there. Licenses were usually on a per-transmitter basis, but some were on a geographic-area basis (BTA, if I recall).

      The rules were changed last year; the names "MDS" and "MMDS" were merged into "BRS". The adjacent "ITFS" channels, used by educational institutions but often partially leased out too, were renamed "EBS". More imporantly, the FCC ordered frequencies to be re-jiggered, with the cost of rearranging everyone in an MTA left to the company that initiates the request. Existing licenses remain in effect, however, on their old and later new frequencies within that band.

      Because many licenses (all ITFS and most MMDS) were on a radius basis, there are some gaps between the license coverage areas. The FCC plans to auction these off on a geographic area basis. So you can't file for a license any more (unless you're eligible for an EBS license and there's a free channel). Instead, you'll be able to purchase the license at auction. It'll be for the geography minus the 35-mile radii of older licensees -- think "Swiss cheese".

      BTW the bulk of BRS licenses belong now to Nextel (who bought most of them from MCI/Worldcom) and Sprint (through many acquisitions); when those two merge, the band will be largely theirs, period.

      The 3650 MHz band provides a possible alternative, but the new rules are not out yet; three regions of the country are out, because of existing federal users (I hope the Report and Order is specific about their locations).

      First, the old and new band plans would help illustrate things. When someone was granted an MMDS or ITFS license, they received permission for certain channels. Typically, people applied for omnidirectional coverage, giving them a protected 35 mile circle. Most markets aren't saturated-- the problem has been consumer acceptance. (Markets have tended to be specialized niche markets. Satellite based DBS arose and answered most of the market need MMDS was envisioned to serve.)

      The realignment of the band is underway as of January 10. The stated purpose of the realignment is creating a place for innovative broadband technologies, especially those that will serve rural markets. If you want to apply for a license, here's the web page. (A starting point only.)

      Nextel, MCI and Sprint only? That begs evidence. While Sprint and others have a strong presence in the market, they are far from monopolizing anything. In many markets, they have to lease stations owned by others. As to the sentiment that all licenses are gone, and if anything pops up, it will be auctioned, again that begs for evidence. Got to the FCC ULS search, and enter callsign WQBG566. They were granted a BRS license the end of September. (They are in group MD-- commercial, not in the VX educational group.)

    Nobody is going to pay millions of dollars to have to cooperate and share... millions are only payed when a monopoly is guaranteed.


    Unfortunately, some of the protocols (like WiMAX) assign timeslots. That means somebody arbitrates the timeslots. That somebody is the base station - or the station "performing the base station role". (When you're doing a WiMAX mesh it gets more complicated...)

    Notice that the FCC is licensing the base stations...

    The way I read this: WiMAX base stations need to perform local mastering functions in order to assign timeslots and subchannels in their region - while WiMAX non-base stations ("subscriber stations" in WiMAX standard-ese, but think of it as "the ordinary guys") defer administrative decisions to base stations. That means that, if you set up a contention-based protocol between base stations to divvy up bandwidth-authority in their vicinities, the base stations are in a position to cheat by asking for more than their share and the subscriber stations are not.

    So the FCC is requiring base stations to obtain a license. This means they can identify them and subject them to greater scrutiny. And it means they can revoke the license if they're found to be cheating, and bring charges and levy fines against any who are violating the terms of their license, as well as anyone who operates a base station without getting a license.

    This doesn't hamper people who want to set up a mesh of non-"base station" peers, provided they use a contention-based protocol that defers to any licensed base stations within range. No base stations & contention based means no license required.

If anything, they should offer the service at a severely discounted rate - less than the current market competitors. This could influence the adaptation of the service and integration into society.

The only problem is, Darnell, the daddy of the 8 pr0n-watching kiddies, is probably not going to be a candidate since he's more than likely too broke to afford a computer - meaning he knows nothing about supporting end-users and services.

Mass taxation is not the way since I forementioned most people having access to other ISPs. This could likely turn ugly since some ISPs might interpret this as a "get the hell out of our city" maneuver.
