Dear Chairman Powells

              Nera Inc. based in Plano, TX, is writing to express ts concerns aboutissues
aised in two related proceedings: ()) reconsideration of the Commission‘s Order authorizing
"ATC"as an extension of Mobile Satellite Service (MSS) networks, and (i) the Commission‘s
   iew ofthe first authorization to implement ATC.
                 Nera Inc. is a manufacturer and system integrator of a wide array of satelite and
terrestrial wireless communications systems, and a global leader in Inmarsat systems and
networking, with a wide variety of U.S. government, military, and commercial customers. Nera
Inc. urges the Commission to ensure that MSS services in the L—Band remain protected from
ATC interference, and to preserve the ability to deploy new and innovative MSS services in all
parts of the United States, urban, suburban and rural, now and in the future.
                The rules that the Commission adopted to constrain ATC interference are under
assault on two fronts. First, Mobile Satellite Ventures (MSV) has asked the Commission to
revise itsrules and allow MSV to significantly increase ATC interference in a manner that would
substantially increase the zones around ATC base stations where Inmarsat terminals will no
longer work, and in a manner that also could degrade or interrupt communications over Inmarsat
spacecraft. Second, in granting the very first ATC license, the International Bureau granted
waivers of certain of these rules and also placed a newburden on MSS operators to demonstrate,
in a very short time frame, that they will be hurt by the deployment of an ATC base station.
        The fact is that no one has identified a way to fully prevent ATC from generating
interference into Inmarsat mobile terminals or Inmarsat spacecraft. The Commission‘s current
ATC rules go a long way toward constraining ATC interference into MSS services, and it is


essential that the Commission maintain and enforce those rules. Moreover, it is critial that the
Commission maintain its current policies that (i) deviations from its ATC rules will be allowed
only if it is demonstrated that the deviations will not increase ATC interference into MSS, (i)
ATC in the L—Band is to be phased in toallow time to study its real world effects, and (it) if
ATC does cause interference into MSS service, an ATC operator must immediately modify or
discontinue its operations. There are two main reasons these protections and policies must be
maintained.
                 First, the continued reliability of Inmarsat services is essential to the safety and
security—related communications of many federal, state and local governmental agencies.
Inmarsat MSS terminals were relied on in New York City following the September 11 attacks,
and the Fire Department ofNew York has recently chosen Inmarsat terminals to support its
emergeney response communications., Inmarsat MSS service is relied on for these purposes
because the system is independent ofthe terrestrial and cellular communications networks that
may be unavailable or overwhelmed in an emergeney. MSS—based safety and security—related
communications simply cannot be atrisk of ATC interference in the time of an emergency, when
police, firefighters and other rescue personnel need reliable communications the most
                 Second, we are just beginning to realize the potential for MSS to support
broadband service across America, in urban, suburban, and rural areas alike. The Inmarsat—4
spacecraft that are about to be launched will support transmission rates of432 kilobits per
second———a rate competitive with planned 3G networks. It therefore is not difficult to imagine the
new types of land mobile, aeronautical, and maritime MSS services that soon will be offered.
Inmarsat‘s new BGAN land mobile service will support the extension of corporate
communications networks, as well as facilitate the provision ofhigh quality live video feeds and
news gathering in urban areas. In addition, Inmarsat‘s new broadband aeronautical capabilities
will provide the opportunity to augment the congested air raffic control system in the U.S.,as
well as offer communications services to the general aviation industry———commercial and private
aireraft ofall sizes. Inmarsat—4 thus provides a unique opportunity———in fact, the only
opportunity——to provide "always—on" broadband services to airplanes, land mobile, and maritime
users, regardless of their location.
                 The full potential ofMSS broadband services can come to fruition only if the
Commission looks forward, and develops ATC rules and policies that protect the future, rather
than simply protecting past MSS technology. For these reasons, it is citical that Inmarsat land
mobile, aeronautical and maritime terminals are protected from interference whenever they are
operated in the vicinity ofATC base stations.
                 ATG, as a secondary, non—interfering service, should not be allowed to constrain
the continued deployment of MSS throughout the United States. Unfortunately, the FCC has
mistakenly assumed that (x) ATC will be deployed only in undefined urban areas, and (y)
Inmarsat land mobile and aeronutical terminals will not be operated over or near those base
stations. If Inmarsat or one of ts U.S. distributors wants to protect its operations in the vicinity
offan ATC base station that will operate at high power, it now has to do two things ()) make a
showing at the FCC within a thirty day window that itlikely will have a mobile user in the
vicinity of the base station, and (i) coordinate with MSV to try to avoid the effects of ATC
interference. If those efforts are not successful, Inmarsat MSS service might not be possible in
the vicinity of that base station in the future.


              MSS subscribers reasonably expect that their terminals will work anywhere they
need them to work. The Commission should not require MSS service providers to make advance
showings in order to protect their operations in the vicinity of an ATC base station.
             These proceedings raise very important policy issues and we urge the
Commission to give them its fullest attention and protect MSS service as described above.
An original and seven copics ofthis letter are enclosed.

                                             Respectfully submitted,

                                             Nera Inc.
