Site Planning
Site Planning
Licensing and availability of space help to determine a site selection. On a
Motorola owned or controlled site, field engineering and program
management plan the system and site layouts. Planning helps to prevent
potential on-site and off-site interference from other RF systems. Site
layouts should always be planned to minimize inter-cabling lengths between
RF equipment.
Site Considerations
The site building should not contain windows and must be able to resist
extreme weather conditions. It should be designed to meet the requirements
of the American National Standards,
Building Code Requirements for
Minimum Design Loads in Buildings and Other Structures
.
Motorola recommends the following considerations when selecting a site:
■
A minimum floor space of at least 200 square feet is recommended to
allow enough space for front and rear access to the equipment cabinets.
■
The minimum ceiling height of at least 8’-6” above a finished floor is
required to allow enough space for the height of the equipment cabinets
and cable access at the top of the cabinets.
■
The ceiling structure should be able to support a cable tray assembly for
routing the intercabinet cabling and other site cabling. The cable tray
assembly is mounted to the site ceiling and walls per site plan and should
be at least 7’-6” from the site floor to allow for the height of equipment
cabinets.
■
The minimum door dimensions should be at least 3’ wide and 6’-8” high.
■
All exterior doors should have tamper proof locks installed for security
purposes.
■
The interior site environment should be maintained at a constant
78° F (25.6° C). The site should be capable of maintaining this
temperature in an outside ambient temperature range of -10 to +105° F
(-23.4 to +40.6° C). iDEN equipment is not approved or recommended for
outdoor use.
■
Proper surge protection is required for all antennas and power inputs to
prevent potential damage to site equipment.
