DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES CHAPTER 3: COMMUNICATION SITE BUILDING DESIGN AND INSTALLATION • Dedicated radio room within a new or existing building: Self-contained outdoor cabinets (land or rooftop), or semi/fully underground vaults. These are often used where zoning or site availability are issues, sometimes in conjunction with camouflaged towers or antennas. • Pre-fabricated equipment shelter of concrete/fiberglass construction: The shelter may be installed at an existing tower site, a new tower site (green site) or on the roof of an existing building. • A “shipping container” that has been outfitted as a self-contained radio site must meet strict dimensional requirements, including protrusions such as HVAC, RF entry assemblies, or AC entrances, and must conform to applicable shipping requirements. • Renovation where an existing building or room is modified or retrofitted to accommodate a new communications system. • A new “green site” on undeveloped land. 3.2 DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES This manual defines and distinguishes various site types as described in Table 3-1. TABLE 3-1 STANDARD DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES Site Type Description Notes Building A permanent structure built on a foundation, containing communications equipment and related ancillary support systems, and which may contain other unrelated equipment and/or facilities. A building shall be suitable for human occupancy during equipment installation, maintenance, and use. A building typically does not have equipment or supporting systems (cable trays, antenna ports, etc.) installed before general installation. Consists of dedicated site structures as well as interior installations such as shared commercial space in existing buildings, dispatch centers, central office installations, and other sites occupied, on a regular basis, by operations-related and possibly other personnel. Example: A dedicated dispatch center and communication equipment site within a dedicated, permanently occupied facility. 3-2 68P81089E50-B 9/1/05
STANDARDS AND GUIDELINES FOR COMMUNICATION SITES DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES TABLE 3-1 STANDARD DEFINITIONS OF COMMUNICATIONS EQUIPMENT SITES (CONTINUED) Site Type Description Notes Shelter A permanent structure built on a foundation that contains communications equipment and related ancillary support systems. A shelter shall be suitable for temporary or permanent human occupancy during equipment installation, maintenance, and use. Example: (See Figure 3-1.) A prefabricated building, usually located with a tower or rooftop antenna system, which houses equipment related only to over-the-air communications. The shelter supports personnel only on a limited basis for installation and maintenance functions; a dispatch center would be located elsewhere in this case. Cabinet/ Enclosure An enclosure that houses communications equipment and ancillary systems only, designed such that equipment contained within can be accessed without the need for personnel to enter the cabinet. An enclosure is typically prewired and its equipment is pre-installed. Example: (See Figure 3-2 and Figure 3-4.) An unmanned, weather-tight enclosure. Consists of smaller buildings or prefabricated shelters containing only equipment directly related to the function of the site. A shelter is intended for human occupancy only during equipment installation and maintenance. The Motorola Standard Building (MSB) is a predesigned all-inclusive self-contained equipment shelter. FIGURE 3-1 TYPICAL PRE-FABRICATED EQUIPMENT SHELTER A cabinet/enclosure can be installed indoors or outdoors, placed on a small foundation, or wall/pole mounted. A cabinet installed indoors uses the existing building environment (heat and air conditioning) to maintain temperature requirements. An outdoor cabinet contains its own environmental controls.
