Overview
This chapter provides the procedures and information to verify that the site is ready for
equipment installation. It also provides procedures to ensure the safety of the installation
personnel, protect the equipment from damage, and verify the site layout parameters.
Ev ery effort should be made to pro vide a safe working en vironment for all installation
and service personnel.
Installation
This Base Control Unit (B CU) may be installed indoors or outdoors. The RF Head is installed
outdoors. The site preparation depends on the type of installation and the site characteristics.
Site Manager
The site manager is the person in charge of and responsible for the full site.
Verication and Procedures
V erifications typically have the installer check with the site manager that a condition has been
previously checked or procedure previously performed and meets a stated specification.
Inspections typically have the installer personally checking that a condition or item meets
stated specifications.
The verifications and procedures provided in this chapter are:
•Internal site inspections
•Preparing site for the arrival of equipment
•Site layout verification

units to the pallets.
The B CU is shipped with all cards/modules and internal cabling installed.
The RF Head is shipped fully assembled.
How Equipment Arrives
Before the equipment arrives, indicate to the transport company an area at the site where the
equipment can be unloaded and, if necessary , unpacked. The equipment should be carefully
delivered to the site, along with all equipment dollies and padding required to safely move the
equipment from the unloading area to the cell site. The site should also have the following items
available: outdoor weather protection and power for temporary lighting and power tools.
Unpacking
The unpacking process requires that the following procedures be completed in the order shown:

■
■
The objective of this procedure is to install the power and earth ground cabling for the Base
Control Unit (B CU) and RF Head.
The site should have had an external ground ring or bus bar being used. The ground ring and
bus bar should be an integral part of the structures that will hold the equipment. Reference
Hard copy (Motorola P art Number 6881089E50)
.
Grounding Considerations
Above Ground F or ground rings and the interconnection of internal and external ground
rings, #2 to #6 A WG may be used. F or grounding of equipment and miscellaneous metallic
objects, #6 A WG minimum is required.
Exceptions Connection from an isolated ground bar (IGB) to master ground bar (MGB) is
accomplished using #2 to #6 A WG . The external ground bar (EGB) is grounded through a 2 -inch
(50.8 mm) wide, 16 -gauge copper strap, if available; otherwise, 2 -#6 A WG wires can be used. If
the #6 A WG wires are used, then they must be connected at opposite ends of the EGB and have
a minimum separation of 12 -inches between them.
Below Ground All wire must be #2 A WG as a minimum. Ground rods are to be a minimum of
8 feet long and 5/8 -inch in diameter . In the case of a deep basement next to the rod, the rod
must be long enough to extend 3 feet below the basement floor .
BCU Grounding
The B CU should be tied to a single point grounded to the system master ground (ground bus
bar). All interconnect cables should be in metallic sealtight type conduit or solid shield RF
cables. It is recommended that these cables be run in raceways to reduce the loop dimensions
of the cable runs. This minimizes the effect of inducted currents caused by the intense
electromagnetic field of lightning current. A ground stud is provided on the external surface of
the B CU enclosure to attach the ground wire. Refer to requirements for cable A in T able 3 -1 .
RF Head Grounding
All RF cables should be in metallic sealtight type conduit or solid shield RF cables. It is
recommended that these cables be run in raceways to reduce the loop dimensions of the cable
runs. This minimizes the effect of inducted currents caused by the intense electromagnetic field
of lightning current. A ground lug with captive screws is provided on the RF Head to attach
the ground wire.

DC Power Grounding
The DC power cables from the B CU to the RF Head are routed through conduit. The conduit
is grounded to the master ground. The ground for the DC cable is attached DC power surge
protect module. See Figure 4 -11
AC Power Grounding
The AC power cables from the B CU to the RF Head are routed through conduit and into the
B CU . The conduit is grounded to the master ground. The ground for the AC cable is attached AC
power surge protect module. See Figure 4 -10 .
Antenna Grounding
The antenna is grounded through the RF Head.

GPS satellites.
68P09277A59 -8 3 -11
PRELIMINARY - UNDER DEVELOPMENT MA Y 2007
R emote GPS Cable Chapter 3: Cable Descriptions
•The mounting pipe for the RGPS head should be mounted vertically with less than five
degrees of tilt.
•It is recommended that the RGPS head be installed using the supplied mounting mast and
mounting hardware. Care should be taken to ensure that the RGPS chassis does not come
into contact with any metal surfaces. F ailure to properly isolate the RGPS chassis from
other conductive surfaces can lead to RGPS head failure. The supplied mounting hardware
has been designed to provide the required RGPS chassis isolation.
•P osition the RGPS head to have an unobstructed view of the sky and to minimize the chance
of debris (leaves, dirt, snow , ice, etc.) accumulating on the radome of the RGPS head.
•The RGPS head must have a clear view of the sky , preferably to within 10 degrees of the
horizon in all directions. The total blockage of the sky (due to buildings, mountains, etc.)
should be less than 50%.
•Place the RGPS head as far away from the transmit antenna as possible to avoid RF
interference issues.
•Place the RGPS head at least 15 m away from lightning rods, towers, or structures that
attract lightning. RGPS head damage is usually not the result of a direct lightning strike,
but of a lightning strike on a nearby structure. Also, since a lightning rod is connected
to an earth ground, it can act as a shield and create a shadow that may block or reduce
the signal from a satellite.
•A fter the Base Control Unit (B CU) is powered up (approximately 15 minutes), check the
RGPS signal strengths with the
gstatus
command on the B CU MMI port.
An optimal installation will have at least one satellite (SV) with an RS SI value 50,
and three (3) satellites with RS SI values 45.
A minimal installation should have at least four (4) satellites with RS SI values 40.
•The RGPS head is rated for ambient air temperatures from –40°C (–40°F) to 75°C (167°F),
and has ratings for humidity , shock, waterproof , UV light resistance, vibrations, salt fog,
ESD , EMI, and altitude.
•The RGPS system used for the Access P oint will support up to 1 km (3280 ft.) of overall
cable length from the RGPS head. If a long cable run needs to be broken into pieces,
minimize the number of breaks in the cable.

The Local GPS Head requires a clear view of the sky , preferably to within ten (10)
degrees of the horizon in all directions. The more sky that is observed increases
the number of potential satellites that can be tracked, resulting in better Local
GPS performance.

includes everything to within ten (10) degrees of the horizon in all directions. RF
obstructions include buildings, towers, natural rock formations, snow , foliage, and
debris.
The mounting of the Local GPS head on antenna towers is not
recommended due to increased risk of damage due to lightning strikes. If
tower mounting is necessary the Local GPS head should mounted at the
lowest point possible and still maintain an unobstructed view of the sky .
5
Separate the Local GPS Head from other radiating sources. Excessive RF energy
can degrade the Local GPS Head’s ability to observe the GPS satellites. The Local
GPS Head receives on the GPS L1 frequency of 1575.42 MHz and incorporates
filters to minimize the effects of potential RF interference, however , strong radiants
can overwhelm the filters, thus degrading the units reception capability .
6
The Local GPS Head is rated for ambient air temperatures in the range -40 to +50
degrees C , and has ratings for humidity , shock, waterproofing, UV light resistance,
vibrations, salt, fog, ESD , EMI, and altitude.
7
An RF gain of between +10 dB and +26 dB should be provided to the Local GPS
receiver antenna input. The GPS antenna supplied in the CGDSGPSKITF4NM50
kit provides a nominal gain of +25 dB. The total signal loss from the
CGDSGPSKITF4NM50 antenna output and Local GPS antenna input must be less
than 15 dB at 1.575 GHz.
