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.

Installing Flexi Zone Micro BTS Installing and Cabling Flexi Zone Micro BTS

10 DN09158885 Issue: 01B



• 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.

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.

1 Connect the omnidirectional antennas to each of the TX/RX ports.

2 Hand-tighten the antenna.

Make sure to grip the antenna by its base and not by its radome.


2.3 Installing Third Party Antennas

1 Connect the antennas to the proper main and diversity TX/RX port on the BTSusing appropriately rated RF cables.

Note the following:

• The only antennas that are permitted to be directly connected to the Flexi ZoneMicro BTS are the antennas specifically offered by NSN for BTS directattachments as listed in sections Installing Directional Antenna and InstallingOmnidirectional Antennas. Other antennas are not supported to be directlyattached to the Flexi Zone Micro unit.

• If any other RF antennas are used they must be remotely mounted (separatelyfrom the FZM unit) and attached using appropriately rated RF cables.

g Remotely located antennas must meet the requirements stipulated in theantenna installation section in the installation manual and be equippedwith additional in-line surge protection.

• If using remotely connected antennas a surge arrestor should always beemployed at the RF antenna cable building or outdoor BTS enclosure entry pointto protect cellsite equipment and for operator safety. The surge arrestor shouldbe connected to the cellsite single point ground using a low impedanceconductor. The surge arrestor should have a low insertion loss within the RFband of operation.

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.

Requirements for GPS antenna installation Installing and Cabling Flexi Zone Micro BTS

52 DN09158885 Issue: 01B



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.

Installing and Cabling Flexi Zone Micro BTS Requirements for GPS antenna installation

Issue: 01B DN09158885 53



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.

Figure 56 Maximizing GPS Antenna Visibility


54 DN09158885 Issue: 01B



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.


Issue: 01B DN09158885 55



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.

Figure 58 Maximum GPS Receiver Interference Power Level vs. Frequency

5.3 Integrated GPS antenna operation

For typical configuration, the GPS antenna is directly mounted on the Flexi Zone Micro

BTS, as shown in Figure 59: Typical RF GPS Antenna Configuration Diagram.

Figure 59 Typical RF GPS Antenna Configuration Diagram


56 DN09158885 Issue: 01B



5.4 Remotely positioned antenna operation

The FZM supports direct GPS antenna mounting as shown in Figure 59: Typical RF GPS

Antenna Configuration Diagram. Figure 59: Typical RF GPS Antenna Configuration

Diagram depicts the connections and hardware where it is necessary to position the

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.


Issue: 01B DN09158885 57



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

Requirement / Recommendations

Gain +25dB (recommended)

Noise Figure <2.5dB (recommended)

Operating Frequency 1575.42 MHz with less than 3dB attenuation at a +1.2MHz offset from center (Required)

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

Radius Data.

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


60 DN09158885 Issue: 01B



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)
