Installing Flexi Zone Micro BTS


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 the device under required circumstances. Evaluation of the wall structure and fastening 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: •

10

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.

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.

1.2 Installing Flexi Zone Micro BTS on a vertical pole Purpose Use the interface bracket, the static mounting bracket and band straps for installing Flexi Zone Micro BTS on a pole. 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. The pole diameter depends on chosen band straps. Before you start

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 required circumstances. 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 mounting pole and hardware prior to installation. The BTS interface panel should always face the ground. Figure 9



When selecting a location to mount the BTS keep the following in mind:

The band straps are not a part of delivery and should be ordered separately.

CAUTION! Risk of personal injury. Ensure that the selected band straps can sustain the device under required circumstances. 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. Figure 16



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.

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.

•

g

The only antennas that are permitted to be directly connected to the Flexi Zone Micro BTS are the antennas specifically offered by NSN for BTS direct attachments as listed in sections Installing Directional Antenna and Installing Omnidirectional Antennas. Other antennas are not supported to be directly attached to the Flexi Zone Micro unit. If any other RF antennas are used they must be remotely mounted (separately from the FZM unit) and attached using appropriately rated RF cables. Remotely located antennas must meet the requirements stipulated in the antenna installation section in the installation manual and be equipped with additional in-line surge protection.

•

If using remotely connected antennas a surge arrestor should always be employed at the RF antenna cable building or outdoor BTS enclosure entry point to protect cellsite equipment and for operator safety. The surge arrestor should be connected to the cellsite single point ground using a low impedance conductor. The surge arrestor should have a low insertion loss within the RF band of operation.

Requirements for GPS antenna installation


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 radionavigation 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 3 active 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.

52

DN09158885

Issue: 01B


Figure 55

5.1.2.2


Cellsite GPS Satellite Visibility

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.

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

54

Maximizing GPS Antenna Visibility

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 an antenna 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

5.2.4

GPS Antenna Placement Considerations

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 the direct 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 antenn a 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

5.4 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

5.4.1

Remote RF GPS Antenna Configuration Diagram

Active GPS Antenna The GPS antenna is used to capture and amplify transmissions from multiple in view GPS satellites while providing adequate rejection of o ut 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 +5V DC ±0.5V bias provided from the Flexi Zone Micro BTS through the GPS antenna cabling.

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 field performance.

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 and environmental 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, arm or 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.

Care must be exercised in properly terminating and weather-proofing all cable connections. A common problem experienced with GPS antenna installations involves poor cable terminations or weather-proofing that result in degraded performance over time and eventual failures.

5.4.3

Lightning Arrestor A surge arrestor should always be employed at the GPS antenna cable building or outdoor BTS enclosure entry point to protect cellsite equipment and for operator safety. The surge arrestor should be connected to the cellsite single point ground using a low impedance conductor as shown in Figure 59: Typical RF GPS Antenna Configuration Diagram. The surge arrestor should have a low insertion loss within the GPS L1 band and must be capable of passing the antenna LNA 5VDC supply voltage. The Polyphaser DGXZ+06NFNF-A surge arrestor is NSN recommended because of its low clamping voltage and high surge handling capabilities. The DGXZ+06NFNF-A has the following performance specifications:

GPS Antenna System RF Requirements To realize optimal GPS receiver performance the total GPS antenna system gain and noise figure at the Flexi Zone Micro BTS GPS antenna input must meet the following requirements: Total Antenna System Gain (G): +10dB > G > +26dB (Within the GPS L1 band (1575.42MHz +1.023MHz)) Total Antenna System Noise Figure: < 4.0dB Operation outside of these limits can negatively impact receiver operation. Potential negative impacts include increased cellsite initialization times, the intermittent GPS signal reception and a reduction in receiver interference immunity.

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 + 0.2dB connector loss ) GLightning Arrestor = -0.1dB (Polyphaser DGXZ+06NFNF-A) GCable 2 = -0.65dB (3m FSJ4-50 cable (0.15dB/m * 3m + 0.2dB connector 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 2 - 1 f 3 - 1 + + ..., f = f 1 + g g1 * g2 1 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 be addressed 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. Figure 61

Safety for Public and Workers

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 with NSN 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.
