.An LPRS transmitter may be operated within the territo-rial limits of the 50 United States, the District of Columbia,and the Caribbean and Pacific insular areas.It also may beoperated on or over any other area of the world, exceptwithin the territorial limits of areas where radio communi-cations are regulated by another agency of the United Statesor within the territorial limits of any foreign government.The transmitting antenna must not exceed 30.5 meters (100feet) above ground level.This height limitation does notapply, however, to LPRS transmitter units located indoors orwhere the antenna is an integral part of the unit.There are 260 channels available for LPRS.These chan-nels are available on a shared basis only and are notassigned for the exclusive use of any entity.Certain channels(19, 20, 50, and 151 to 160) are reserved for law enforcementtracking purposes.Further, AMTS-related transmissionsare limited to the upper portion of the band (216.750 to217.000 MHz).Users must cooperate in the selection and use of channelsin order to reduce interference and make the most effectiveuse of the authorized facilities.Channels must be selected inan effort to avoid interference with other LPRS transmis-sions.This means that if users are experiencing interferenceon a particular channel, they should change to another chan-nel until a clear one is found.Finally, operation is subject to the conditions that noharmful interference is caused to the U.S.Navy s SPASURradar system (216.88 to 217.08 MHz) or to a Channel 13 tele-vision station.SummaryLPRS can operate anywhere CB station operation is permit-ted.An LPRS station is not required to transmit a station 210 LOW-POWER RADIO SERVICEidentification announcement.The LPRS transmitting devicemay not interfere with TV reception or federal governmentradar and must accept any interference received, includinginterference that may cause undesired operation.Onrequest, system equipment must be available for inspectionby an authorized FCC representative.See alsoCitizens Band Radio ServiceFamily Radio ServiceGeneral Mobile Radio Service MMMARITIME MOBILE SERVICEMARITIME MOBILE SERVICEThe Maritime, or Marine, Radio Services have evolved fromthe earliest practical uses of radio.In 1900, just 6 years afterMarconi demonstrated his wireless radio, devices werebeing installed aboard ships to enable them to receive stormwarnings transmitted from stations on shore.Today, thesame principle applies in using both shipboard and land sta-tions in the marine services to safeguard life and property atsea.Both types of stations are also used to aid marine navi-gation, commerce, and personal business, but such uses aresecondary to safety, which has international priority.The Marine Radio Services include the Maritime MobileService, the Maritime Mobile-Satellite Service, the PortOperations Service, the Ship Movement Service, the MaritimeFixed Service, and the Maritime Radiodetermination Service.Maritime Mobile Service is an internationally allocatedradio service providing for safety of life and property atsea and on inland waterways.Maritime Mobile-Satellite Service provides frequenciesfor public correspondence between ships and public coaststations as well as between aircraft and public coast sta-tions and coast earth stations.The transmission of public211Copyright 2003 by The McGraw-Hill Companies, Inc.Click Here for Terms of Use. 212 MARITIME MOBILE SERVICEcorrespondence from aircraft must not cause interferenceto maritime communications.Port Operations Service provides frequencies for inter-ship communications related to port operations in coastalharbors, allowing the vessel traffic to be managed moreefficiently while protecting the marine environment fromvessel collisions and groundings.Ship Movement Service provides frequencies for commu-nications relating to the operational handling of themovement and the safety of ships and, in emergency, tothe safety of persons.Maritime Fixed Service provides frequencies for commu-nications equipment installed on oil drilling platforms,lighthouses, and maritime colleges.Maritime Radiodetermination Service provides frequen-cies for determining position, velocity, and other charac-teristics of vessels [ Pobierz całość w formacie PDF ]
