Max Allowed Antenna Gain

39.1 - (37-6-3) =11.1dBi

39.1- (37-0-3) = 5.1dbi

39.1- (37-10-3) = 15.1dbi

Equation (2) - Input Noise to service antenna

Input Noise to service antenna:

-36 dBm + Service Antenna gain – Antenna splitter losses in dB – cable loss in dB

Product Description and User’s Manual

1.4.4 Antenna Installation

Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on permanent structures.

The FCC regulations mandate that the ERP of type B signal boosters should not exceed 5W, this is equivalent to 8.2W EIRP.

Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by equation 1 (below) for the service antenna.

For example:

1.4.5 Compliance with FCC deployment rule regarding the radiation of noise

Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the

gain of the signal booster should be set so that the ERP of the output noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth.

In the event that the noise level measured exceeds the aforementioned value, the signal booster gain should be decreased accordingly.

In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm in a 10 kHz measurement bandwidth.

The 3302 61-200001 Series Repeater has a noise level of -60 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band noise level at around -36 dBm in a 10 kHz bandwidth. Therefore, the noise at the antenna input port should be calculated based on equation (3).

Axell BSF-3302 61-200001 Series Repeater Product Description and User’s Manual

Example: In band Noise

Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12dB Gain = ~ 2 dBi Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (3) Input antenna noise (to the antenna) = -36+2-12 -11=-57 dBm The in-band input noise to the antenna should be -36+2 -12-11= -57dbm

Example: Out of band noise

Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12dB Gain = ~ 2 dBi Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (3) Input antenna noise (to the antenna) = -60+2-11 -15=--81dBm The Out of-band input noise to the antenna should be -60+2 -12-11= -81dbm

NOTE: In this example there is no need to add an external band pass filter to attenuate the out of

band noise. If fewer antennas are deployed then additional filtering may be required

Conclusion:

Good engineering practice requires that in general when the out of band noise measured at the service antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an external band pass filter should be added to attenuate the out of band noise level.

All Axell Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band noise. Should additional filtering be required, we have a comprehensive range of interference filters which can be supplied upon request.

Caution labels!

Throughout this manual, there are "Caution" warnings. "Caution" calls attention to a procedure or practice, which, if ignored, may result in injury or damage to the system, system component or even the user. Do not perform any procedure preceded by a "Caution" until the described conditions are fully understood and met.

Danger:

Electrical Shock

To prevent electrical shock when installing or modifying the system power wiring, disconnect the wiring at the power source before working with un insulated wires or terminals.

Caution:

Safety to personnel

Before installing or replacing any of the equipment, the entire manual should be read and understood.

The user needs to supply the appropriate AC power to the repeater. Incorrect power settings can damage the repeater and may cause injury to the user.

Please be aware that the equipment may, during certain conditions become very warm and can cause minor injuries if handled without any protection, such as gloves.

Caution:

RF Exposure

RF radiation, arising from transmitter outputs connected to AWL’s equipment, must be considered a safety hazard.

This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left un-terminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the

impedance of an N type connector at 50Ω, and that of free space at

377Ω, which would severely compromise the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched!

Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended.

Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.

Axell BSF-3302 61-200001 Series Repeater

Product Description and User’s Manual

2 Introduction

The BSF 3302 is a fiber optic fed UHF repeater. It is part of a system that is fed from an Axell Wireless Optical Master Unit Mk. 2 (OMU II), supporting WDM technology, lowering the number of fibers needed per system. The maximum optical loss of up to 10dB is allowed over the fiber interconnecting the OMU II and the most distant last remote unit that the OMU supports. This offers great flexibility when providing RF coverage in areas where it is not possible to rely on off-air transmission.

The fiber optic system is easily remotely monitored and controlled by Axell Wireless’ effective supervision tool, The Axell Wireless Element Manager (AEM).

The BSF-3302 includes automatic optical gain settings, where the gain is adjusted in the downlink chain by measuring the level of the pilot carrier sent from the OMU II. The level of the received pilot carrier is continuously monitored.

Product Description and User’s Manual

2.2 Automatic Level Control

The repeater is equipped with Automatic Level Control (ALC). The ALC feature enables maintaining the maximum defined output level.

The repeater has a defined maximum output level. If the input signal amplified by the gain set exceeds the set output limit, an ALC loop is activated. This ALC ensures that the amplifier does not add distortion to the radio signal. Below are examples of the ALC function for one and two carriers.

2.3 Operating Temperature

The BSF-3302 is designed primarily for multi carrier purposes. If the repeater is run at full output power over a long period of time, the convection cooling may not be enough. The repeater is equipped with a power management function that steps down the power and, if needed, fully shuts down the amplifier chains until temperature reaches normal values. In situations where a repeater will be run in such a manner extra cooling can be provided by putting the repeater in a temperature controlled environment or via external fans.

3.2 Service Antenna Requirements

a. The installer is held accountable for implementing the rules required for

deployment. b. Good engineering practice must be used to avoid interference. c. Output power should be reduced to solve any IMD interference issues.

The Service antenna type (i.e. the antenna feeding the mobile/remote units) depends on the design of the DAS.

3.2.1 Required Antenna Information

The following antenna requirements, specifications and site considerations should be met:

● Type of installation – DAS/Radiating Cable

● Service area type and size

● Antenna type and characteristics

● Height

● Length and type of coaxial cable required for connecting the antenna to the Repeater and

the attenuation.

3.2.2 Indoor Installations

3.2.2.1 Recommended Antennas

The following describes the requirements for an omnidirectional mobile used for indoor applications.

Specifications:

● One or a combination of the following antennas can be used: Ceiling Mount Patch antenna, Wall Mount Patch antenna, Corner Reflector.

● Choose an antenna with high side lobe attenuation which enables maximum isolation from other co-located antennas.

●

Equation (1) - Max SERVICE antenna gain

Max SERVICE antenna gain (dBi) = 39.1 – (37dBm - # of antennas in dB – cable losses in dB).

For example:

Typical Antenna Types:

● Indoor Dome 2.1dBi beam width 360o

● Indoor Panel 4.2dBi beam width 106o

● Radiating Cable Typically < -50dBi

3.2.2.2 Recommended Splitters and Couplers

Axell Wireless can supply a comprehensive range of splitters and Couplers to aid the installation of

the DAS system. Typical specifications as below:

3.2.2.3 Installation Criteria

Determine the antenna installation configuration, according to the transmission requirements and the installation site conditions.

Installation requirements:

● An indoor antenna should be installed at a convenient location. It should be free of metallic obstruction.

Install the Service Antenna at the designated height and tune it roughly toward the Service coverage area.

3.2.3 Service (Mobile) Antenna Installation Criteria

Determine the antenna installation configuration, according to the transmission requirements and the installation site conditions.

Installation requirements:

● An indoor antenna should be installed at a convenient location. It should be free of metallic obstruction.

● Install the Service Antenna at the designated height and tune it roughly toward the Service coverage area.

● Installation of this antenna must provide a minimum separation distance of 58 cm from any personnel within the area.

3.3 RF Cabling Requirements

● For all coaxial connections to/from the Repeater - high performance, flexible, low loss 50Ω coaxial communications cable.

● All cables shall be weather-resistant type.

● Cable length - determined by the Repeater installation plan. When calculating the cable

length, take into account excess cable slack so as not to limit the insertion paths.

● Make sure that cable and connector are compatible. Using cables and connectors from the same manufacturer is helpful.

● All connectors must be clean and dry

● Waterproof all outdoor connections using silicone, vulcanizable tape or other suitable

substance as moisture and dust can impair RF characteristics.

● Make sure enough room has been allocated for the bending radius of the cable. RF cables must not be kinked, cut or damaged in any way

● Connect the RF cable to the antenna tightly but without damaging threads

● Fasten cables tight to cable ladder or aluminum sheet

● For short length of feeder cables use ½ “, for longer feeder cables use 7/8”. Chose thicker

coax cables for lower attenuation. Minimize the length of the coax cables to reduce the attenuation

● Use jumper cable for easy installation. The RF Coaxial cable can be substituted at each end with a jumper cable.

4.2.1 Selecting a Location to Ensure Proper Cooling

● Mount the repeater so that heat can be dispersed from it.

● The repeater wall mounting brackets ensure an optimum airflow between the wall and the

heat-sink on the rear of the repeater.

● Do not block this air channel as it will cause the MTBF of the repeater to drop dramatically, or even in the worst case cause the repeater to fail completely.

● If possible, use a wall in the shade to minimize the overall sun loading. If sufficient shielding cannot be obtained, an additional sun shield should be mounted.

Figure 4-1: Example of a sun shield

4.2.2 Wall-Mounting Preparation

It is recommended that two people lift the repeater since (depending upon the

configuration) the BSF-3302 weighs approximately 30 kg.

● Wall compatibility - check the suitability of the wall on which the BSF-3302 is to be to be fitted.

● Plan mount - check the actual fixing centres (see below) and overall dimensions of the BSF-3302 enclosure. The BSF-3302 is fitted with wall mounting brackets which provide adequate ventilation between the BSF-3302 and the wall to which it is fixed.

● Plan connection cable clearances - the Optical, RF and power connections located on the side of the BSF-3302 will need at least 300mm clearance to enable the connections to be made. The minimum bend radius for Optical and RF cables must not be less than the recommendations made by the cable manufacturer. Plan the cable runs and ensure adequate space is available.

● Allow for door opening - ensure that there is sufficient space at the front of the BSF- 3302 to allow the door to be fully opened and for maintenance engineers to get access to the unit with test equipment such as a spectrum analyzer. Allow an additional 500mm of space in front of the BSF-3302 when the door is fully open.

● Fix bolts –fix M8 Rawbolts or similar (100mm in length) into the wall at the dimensions as illustrated in figure 1 below using equipment as specified by the fixing manufacturer. A recommended method is set out below. Care must be taken to ensure the alignment of the four fixings. A spirit level or plumb line should be used to ensure horizontal/vertical alignment.
