1 Installing Flexi Zone Micro BTS
1.1 Installing Flexi Zone Micro BTS on a wall
Purpose
Use the interface bracket and the static mounting bracket for installing Flexi Zone Micro
BTS on a wall.
If you want to install the BTS with the directional antenna, the tilting bracket might be
used instead of static mounting bracket. Usage of the tilting bracket allows best
performance and flexibility in controlling the coverage area when using the directional
antenna.
The tilting bracket has the same mounting interfaces as the static mounting bracket,
therefore the following procedure applies also for the tilting bracket installation.
Before you start
w NOTICE: Flexi Zone Micro BTS equipment must be installed by trained and
qualified service personnel in accordance with all local codes and requirements.
w NOTICE: Flexi Zone Micro BTS equipment is intended for installation in
restricted access location or equivalent.
f CAUTION! Risk of personal injury.
Ensure that the wall installation surface and selected fasteners can sustain thedevice under required circumstances. Evaluation of the wall structure andfastening hardware type should be done by a structural engineer.
The BTS interface panel should always face the ground.
Figure 1 Flexi Zone Micro BTS interface panel
Interface panel side of BTS
When selecting a location to mount the BTS keep the following in mind:
• Try to avoid mounting the BTS such that the antennas are blocked by other
structures, walls, etc. A direct line of sight to the area to be covered will provide the
best performance.

• Keep other metallic mounting features as far away from all antennas as possible.
• Keep cables routed and secured away from the LTE and Bluetooth antennas.
• If you plan to use omnidirectional antenna, do not install the BTS on a metal wall or
nearby metal obstructions.• Remotely connecting the FAWB omnidirectional antenna (472933A) is not allowed as
this is a monopole antenna.
• If any omnidirectional or directional antennas are remotely connected, external
lightning surge protection must be added.
If side clearance is less than screw driver length, the grounding cable needs to be pre-
installed. The minimum and recommended maintenance clearances are shown in Table
1: Flexi Zone Micro BTS maintenance clearances.

1.3 Installing Flexi Zone Micro BTS on a horizontal pole
Purpose
Use the interface bracket, the static mounting bracket and band straps for installing Flexi
Zone Micro BTS on a pole.
The pole diameter depends on chosen band straps.
g The tilting bracket is not intended for horizontal pole mount applications.
Before you start
w NOTICE: Flexi Zone Micro BTS equipment must be installed by trained and
qualified service personnel in accordance with all local codes and requirements.
w NOTICE: Flexi Zone Micro BTS equipment is intended for installation in
restricted access location or equivalent.
g The band straps are not a part of delivery and should be ordered separately.
f CAUTION! Risk of personal injury.Ensure that the selected band straps can sustain the device under requiredcircumstances.The selected band straps should be rated for outdoor use and capable of securing the BTS weight. A certified structural engineer should inspect and
approve a mounting pole and the hardware prior to the installation.
The BTS interface panel should always face the ground.

Interface panel side of BTS
When selecting a location to mount the BTS keep the following in mind:
• Try to avoid mounting the BTS such that the antennas are blocked by other
structures, walls, etc. A direct line of sight to the area to be covered will provide the
best performance.
• Keep other metallic mounting features as far away from all antennas as possible.
• Keep cables routed and secured away from the LTE and Bluetooth antennas.

2 Installing Antennas
2.1 Installing Directional Antenna
Purpose
The directional antenna is installed by sliding onto the Flexi Zone Micro BTS. Installing
the BTS on the tilting bracket allows the antenna to tilt both vertically (+/- 15 degrees)
and horizontally (+/- 30 degrees).
Installing the BTS with tilting bracket on a wall or on a vertical pole is done in the same
way as installing the BTS with static mounting bracket.
Before you start
w NOTICE: The directional antenna is meant to be used as attached to the Flexi
Zone Micro BTS. Mounting the antenna remotely could result in slightly worse
performance as the ground plane of the radio is utilized to optimize the gain and
beamwidth.
The directional antenna is equipped with TX monitor ports meant for regulatory
measurements. The ports have -35 dB couplers and require cables with SMA-male
connectors.
Turn off the transmitter power before connecting cables to the monitor ports.
1 Install the static mounting bracket or the tilting bracket.
If you install the BTS on a wall, see Installing Flexi Zone Micro BTS on a wall.
If you install the BTS on a vertical pole, see Installing Flexi Zone Micro BTS on avertical pole.

5 Requirements for GPS antenna installation
5.1 Introduction
5.1.1 Scope
The synchronization of Flexi Zone Micro BTS transmissions is primarily provided by a
Global Positioning System (GPS) timing receiver. A high degree of reliability can be
expected from the BTS GPS timing receiver but the overall receiver performance is
heavily dependant on the GPS antenna installation. To realize the expected GPS
performance the GPS antenna installation must meet requirements regarding antenna
placement, cabling, lightning protection and interference suppression
This section provides a brief overview of the GPS followed by a summary of BTS GPS
antenna installation requirements, guidelines for optimizing antenna installations and
cellsite debugging procedures.
5.1.2 The Global Positioning System
The C/A (Coarse Acquisition) Global Positioning System (GPS) is a space based radio-
navigation system that provides precise three dimensional (3D) positioning and time of
day information to civilian users.
5.1.2.1 Satellite Constellation
The GPS is designed to operate with a minimum constellation of 21 operational and 3active spare (24 total) satellites. The GPS satellite constellation is organized with 6
orbital planes each with an inclination of 55 degrees to the equator and an altitude of
20,200 kilometers. GPS satellite orbits are non-geosynchronous and complete one orbit
in approximately 12 hours. It therefore is important to understand that a GPS receiver is
to be exposed to a varying (but predictable) constellation of satellites which are
constantly moving across the sky.

Figure 55 Cellsite GPS Satellite Visibility
5.1.2.2 GPS RF Carrier
All C/A GPS satellites employ 1.023MHz wide spread spectrum modulation on a
common carrier frequency of 1.57542GHz. GPS transmissions received at the surface of
the Earth should have a minimum RF signal strength of -160dBW.
5.2 General antenna positioning requirements
GPS antenna placement can be one of the most critical factors in realizing reliable BTS
synchronization. The FZM design involves an integrated GPS antenna that allows direct
reception of GPS transmissions when operated in locations that afford a suitable satellite
visibility. In cases where the FZM must be operated in a location that does not provide
suitable satellite visibility the GPS antenna can be detached and positioned in a more
optimal position with connection through a coaxial cable.
Considerations of several (often conflicting) factors are required in determining the
optimal GPS antenna position. The GPS antenna position should ideally be chosen to
provide a maximum view to the horizon in all directions. However, sacrifices in antenna
visibility are often necessary when considering other factors such as RF interference
from nearby transmit antennas or potential antenna damage due to impact from falling
ice or lightning strikes. For example the placement of a GPS antenna atop a cellular
tower would likely provide a maximum satellite visibility but would be a poor positioning
choice because of potential lightning damage or interference from nearby cellsite
transmit antennas.
Consideration must also be given to changing environmental conditions when selecting a
GPS antenna location. Dense foliage can significantly attenuate GPS transmissions and
may not cause problems during fall or winter months but could impact GPS reception
during other seasons or with continued tree growth.

http://slidepdf.com/reader/full/flexizonebtsinst-0900d80580a423e8pdf 54/71
In most cases suitable compromises can be made to obtain the necessary mix of GPS
satellite visibility and protection of antenna hardware.
5.2.1 Required Antenna Visibility A line of sight view is required between the GPS antenna and any satellites used in
determining a timing solution. Before the GPS receiver can provide accurate timing
information it must first determine the location of its antenna in 3D space. The
information from a minimum of four (4) satellites is required to determine the 3D antenna
location. After the GPS receiver has determined its antenna location it can continue to
provide accurate timing information with as few as one (1) satellite in view.
Because GPS satellites operate in non-geosynchronous orbital patterns the GPS
antenna must be prepared to receive GPS signals from most any direction. The
minimum GPS constellation guarantees that a minimum of four (4) GPS satellites are to
be in view from any location on the Earth with an un-obstructed view to the horizon.
Typically however, six (6) or more satellites are visible allowing for some obstruction of the GPS antenna visibility if necessary.
5.2.2 Antenna Placement Optimization
While the ideal GPS antenna installation provides an unobstructed view in all directions
to within 20° of the horizon, practical limitations exist at some cellsite locations that afford
only a fraction of the desired visibility. Reductions in GPS antenna visibility can result in
increased BTS initialization times or in the reporting of numerous alarms from affected
BTS's. Care should be taken in selecting the antenna location to maximize the available
visibility. Even small improvements in visibility can have a large impact in receiver
performance as can be seen in the example presented in Figure 56: Maximizing GPS
Antenna Visibility.

5.2.3 Lightning Protection
The GPS antenna position should be chosen to minimize the potential of damage
because of a direct or nearby lightning strike. In cellsite installations employing anantenna tower it is recommended that the GPS antenna be mounted near the tower base
(but not where it might be impacted by falling ice) to allow the tower to act as a lightning
rod. Many different approaches have been used to define the protective area provided by
a nearby tower or lightning rod such as the 45° protection zone or the rolling ball method.
While the accuracy of these methods has recently come into question the general rule
holds where higher antenna elevations yield a higher probability of damage due to
lightning. The GPS antenna should never be at or near the highest elevation of its
surroundings.
The GPS antenna cabling must be grounded at the cellsite master ground point. If the
GPS antenna must be positioned on or close to the cellsite tower it requires to bond the
antenna and cabling to the tower as well to avoid lightning flashover.
Figure 57 GPS Antenna Placement Considerations
5.2.4 Antenna Blockage
While NSN recommends GPS antennas utilize a conically shaped radome to minimize
the likelihood of blockage due to debris or snow buildup care should still be taken in
positioning the antenna to minimize any such accumulation on the antenna surface.
Mounting the GPS antenna on a pole or mast at an elevation above any potential snow
or debris buildup is a common solution to this problem. The pole or mast mounting also
allows any temporary ice accumulation to quickly dissipate after sever weather
conditions subside.

5.2.5 RF Interference
While the BTS GPS receiver and recommended antennas provide a high level of out of
band interference rejection care should be taken to avoid placing the GPS antenna in thedirect radiation path of cellular or other transmit antennas. To minimize interference
potential the GPS antenna should be positioned at a different elevation and as far as
possible from nearby transmit antennas. The graph presented in Figure 58: Maximum
GPS Receiver Interference Power Level vs. Frequency can be used to identify the
maximum interference source power levels presented at the GPS antenna surface
(assuming that a NSN recommended GPS antenna is in use and RF signal presented to
the GPS receiver meets all level and noise figure requirements).
Different interference rejection performance than what is presented in Figure 57: GPS
Antenna Placement Considerations might be experienced with other (non-NSN
recommended) GPS antenna types or when the GPS receiver is not provided with the
required (minimum or maximum) RF signal levels.

GPS antenna separately from the FZM. A description of the GPS antenna system
elements along with relative installation requirements is presented in following
subsections of this document.
Figure 60 Remote RF GPS Antenna Configuration Diagram
5.4.1 Active GPS Antenna
The GPS antenna is used to capture and amplify transmissions from multiple in view
GPS satellites while providing adequate rejection of out of band signals. The Flexi Zone
Micro BTS GPS antenna consists of an antenna element, pre-selector filter and Low
Noise Amplifier (LNA).
5.4.1.1 Antenna Element
The antenna element must be capable of receiving transmissions from multiple GPS
satellites while in view throughout their orbit. A suitable GPS antenna is to have a nearly
uniform gain throughout a 360° azimuth and to within 20° above the horizon. Extending
antenna gain to elevations of less than 20° offers little benefit in terms of satellite tracking
and can actually make the GPS receiver more vulnerable to terrestrial interference
sources.
5.4.1.2 Low Noise Amplifier (LNA) / Pre-selector Filter
An active antenna is utilized to minimize antenna system noise figure and maximize
usable antenna cable lengths. The Flexi Zone Micro supplied antenna incorporates an
LNA and GPS bandpass filtering.
The active antenna LNA is powered by a +5VDC ±0.5V bias provided from the Flexi Zone
Micro BTS through the GPS antenna cabling.

5.4.1.3 Overall GPS Antenna RF Requirements
The NSN recommended GPS antennas should meet the requirements outlined in Table
4: Recommended GPS Antenna Specifications and have proven quality with good fieldperformance. While it is possible to use other antennas, considerable care must be
exercised in selecting alternatives to insure full BTS compatibility for all conditions.
Table 4 Recommended GPS Antenna Specifications

LNA Supply Current <30mA (Required)
Azimuth Coverage 360° (Required)
Elevation Coverage 10° to 90° (Required)
Operating Temperature -40°C to +85°C (Recommended)
5.4.2 RF Cabling
A wide range of coaxial cable types may be used between the GPS antenna and BTS
connection. In choosing the GPS antenna cable all RF, physical installation andenvironmental requirements must be considered. The GPS antenna cable must have a
characteristic impedance of 50Ω and must satisfy the signal loss requirement outlined in
section GPS Antenna System RF Requirements for the installation length.
The chosen antenna cable must support all installation requirements such as the
minimum cable bend radius, operating temperature range any special insulation
requirements such as ultra-violet light resistance, armor jacketing for rodent proofing,
plenum ratings, etc. Signal loss and minimum bend radius information for commonly
used GPS antenna cable types is presented in Table 5: Antenna Cable Loss / Bend

5.4.4.1 Antenna System Gain
The total antenna system gain can be calculated by summing the gains and losses (in
decibels) of all antenna system elements using the following equation:
G = G Antenna + GCable 1 + GLightning Arrestor + GCable 2
As an example the antenna system gain of a hypothetical cellsite GPS installation
utilizing the following elements (pictured in Figure 61: GPS Antenna Loss Budget / Noise
Figure Calculation) is calculated as follows:
G Antenna = +25dB (Antenna)
GCable 1 = -7.7dB (50m FSJ4-50 cable (0.15dB/m * 50m + 0.2dBconnector loss)
GLightning Arrestor = -0.1dB (Polyphaser DGXZ+06NFNF-A)
GCable 2 = -0.65dB (3m FSJ4-50 cable (0.15dB/m * 3m + 0.2dBconnector loss)
G = +25dB - 7.7dB -0.1dB -0.65dB
G = 16.55dB
The calculated gain of this hypothetical GPS antenna system is +16.55dB which is within
the required gain range of +10dB to +26dB. If the resulting gain were less than +10dB
modifications to the antenna system such as using a lower loss cable to increase the
overall gain would be required.
5.4.4.2 Antenna System Noise Figure
The GPS antenna system noise figure requirement is seldom violated unless a non
recommended GPS antenna is used or additional signal amplifiers are employed to
compensate for large cable losses. The total antenna system noise figure can be
calculated using the following equation:
f = f 1 + f 2 - 1
g1
f 3 - 1+ + . . . ,g1 * g2
Where:
f = the total antenna system noise figure
f 1 = noise figure of stage 1
g1 = gain of stage 1
g All gain and noise figure values are absolute and not in decibels
The noise figure of the hypothetical GPS antenna system described in Antenna System
Gain would be calculated as follows:
f = 1.535
NF(dB) = 10*Log(1.535)=1.86dB
The calculated noise figure of this hypothetical GPS antenna system is 1.86dB which is
below the required +4.0dB maximum. Violations in antenna system noise figure can beaddressed by utilizing lower loss antenna cabling utilizing signal amplifiers with lower

noise figures and reducing the signal losses prior to any in-line signal amplifiers.
Difficulties in satisfying antenna system noise figure requirements are usually caused by
the need to utilize long cable runs.

8 Safety for Public and Workers
8.1 Installing base stations to ensure public safety
The equipment generates radio frequency energy, which has a thermal effect when
absorbed by the human body. For this reason compliance boundaries specific to this
equipment have been established. The thermal effects of radio frequency energy can
exceed safety levels when a person is inside the established compliance boundaries.
Observe the compliance boundary, and make sure the general public has no access to
areas inside the established boundaries.
8.2 Installing base stations to ensure installer safety
Installation engineers need to be aware of the potential risk of the thermal effects of radio
frequency energy and how to protect him/herself against undue risk.
When working close to transmitter antennas, the proper safety distances must be
observed. The minimum safe distance from an antenna is measured in meters. When
assessing the applicable compliance boundaries (CB) European standards EN 50383,
EN 50385, Council Recommendation 1999/519/EC and FCC 47 CFR § 1.1310 for
general public electromagnetic exposure limits have been applied.
The antenna types and gain actually configured on the product determine the minimum
safe distance. Flexi Zone Micro small cell, is compliant with the cited standards at every
point outside the FINAL boundary (CB) when the Flexi Zone Micro BTS is deployed withNSN provided antennas connected directly to the Flexi Zone Micro RF ports.
Consult site engineering plan for any other configurations.
Provisions must be taken to guarantee that no public access is possible to regions within
the FINAL compliance boundaries. See Table 11: Required Compliance Boundaries (CB)
