44、AS) Design and Implementation Best Practices 1 1 Introduction 1.1 Overview A distributed antenna system (DAS) is a group of antennas spatially separated and distributed over a given geographic area to augment existing wireless (e.g., cellular, radio signal) service. Although useful in any circumstan

45、ce where a single antenna is insufficient to provide the service levels expected, sophisticated commercial deployments typically take place in: Medical facilities Educational and industrial campuses Hotels Casinos Airports Tunnels Subways Office complexes Shopping malls Parking garages A DAS may als

46、o be deployed to provide extra network capacity in venues that are infrequently used but are subject to high demand of wireless services such as stadiums, arenas, and auditoriums. A DAS may be deployed either indoors or outdoors. It is a system of antennas typically deployed within isolated areas of

47、 a building or series of buildings, such as a campus, to increase the ubiquity of coverage within the objective. When a DAS is used to provide wireless service as part of an outdoor application, natural or manmade morphological or environmental factors are essential to consider during a full wireles

48、s signal distribution design. When a DAS is used to provide wireless service as part of an indoor application, architectural features, morphologies, and macro environmental impacts are essential to consider. Some commonly retransmitted services of a DAS include: 700 MHz Cellular service (850 MHz) Gl

49、obal System for Mobile Communications (GSM) (900/1800 MHz) Personal communications service (PCS) (1900 MHz) Enhanced specialized mobile radio (ESMR) (800/900 MHz) Advanced Wireless Services (AWS) (1700-2150 MHz) Broadband Radio Services (BRS) (2600 MHz) Public safety and business band land mobile radio (LMR) (150-170 MHz, 450-512 MHz) NOTE: 47CFR90.35 assigns 450-470 MHz to LMR; heavily used for businesses and government. Uncommonly transmitted services of a DAS include:
