Site Planning
Proper licensing and space availability aid in determining a site selection. On a Motorola-
owned or -controlled site, field engineering and program management plan the system and
site layouts. Proper planning helps prevent potential on-site and off-site interference from
other radio frequency (RF) systems. Site layouts should always be planned to minimize
interference between equipment in the Wireless Messaging System.
To verify proper site considerations and recommendations are being followed, refer to the
Motorola Quality Standards - Fixed Network Equipment (FNE) Installation Manual R56 Motorola
part number 6881089E50.
Site Considerations
The site must be able to resist extreme weather conditions and must not have windows. The
site should 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 for site selection:
A minimum floor space of 20 square feet is recommended to allow enough space for
front and rear access to the equipment. The extra space eases the installation, air flow,
and maintenance of the equipment.
The site floor should be level to within 0.125 in. (0.3175 cm) across the foot print of the
cabinet and able to support the weight of the site equipment. Refer to the floor loading
information provided in this chapter.
The minimum ceiling height, above a finished floor, is 102 in. (259.08 cm). This height
allows enough space between the top of the RF-O! paging station equipment cabinet(s)
for cabling access across 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 for each site plan. The cable tray should be at least 90 in. from the site
floor to allow for the height of the equipment cabinets.
