1.1. BEAMER® Module Concept
The BEAMER® is an integrated active antenna for wireless communications. It incorporates a
transmission amplifier, Remote Controlled Gain, transmission band filter and the respective receive
chain: band filter, and Gain controlled LNA.
The Tx amplifier is linear. The Rx amplifier has an exceptional linear dynamic range. The integral unit
contains its own power conditioner and a monitoring and control circuit that communicates with the
RAC and from there on through the Wireless Modem to any remote PC (The Wireless Modem
feature is an option) . The whole unit is sealed and built as a plug-in replaceable unit. The design and
production techniques offer low price and high reliability.

Figure 2: BEAMER® block diagram
The band pass filters (BPF) supply enough Tx/Rx channel isolation to ensure that the small amount of
Tx signal power and Tx wide band noise power leaking into the sensitive receive channel will not
degrade the Rx channel performance. In the FLEXBEAMER® System the BPF are replaced by a
duplexer and the Beamer antenna by a separate sector antenna.
The Rx amplifier is a low noise amplifier with a high enough intercept point that several PCS channels
received simultaneously should not degrade each other's performance. The low noise and high gain
performance of this amplifier compensate for the high losses of the coaxial cable going down from the
Rx BEAMER® front-end to the RAC and BAU and transmitted to the base station. The Tx
Amplifier is a power amplifier that enables up to 10 Watts average at the Tx antenna port. while
compensating for gain and power losses in the coaxial cable coming up from the BAU received from
the base station.

Donor Side Antenna. The FLEXBEAMER® System contains the following units:
• BAU- Beamer Antenna Unit
• RAC- Remote Antenna Controller
• FLEXBEAMER®- Coverage Enlightener Beamer
1.3.1. BAU
Including:
• Duplexer
• Linear P.A (p/o Beamer®)
• LNA. (p/o Beamer®)
1.3.2. RAC
Including:
• RF band selective Filtration
• Rx ACBTs - Programmable gain UP LINK amplifiers, Bias-T
• Tx ACBTs - Programmable gain DOWN LINK amplifiers and Bias-T
• Control and Monitor (C&M) board for:
§ Local PC connection by RS-485 interface to supports software download and system
configuration via a PC and Software (S/W) packages (such as the BSM S/W for

§ Remote interface options include Dial-up wireless modem (as an option).
• Internal 110-220AC power supply and power conditioning
The RAC is the RF interface between the FLEXBEAMER® unit and the BAU, provides the
BEAMER® units in the BAU and the FLEXBEAMER® with the DC power, and control each
individual BEAMER®. It consists of a set of Bias T connections for multiplexing the RF, DC power
and the C&M communication on the RF cables to the BEAMER® units in the BAU and
FLEXBEAMER® units, a modem for communicating with each of the BEAMER® units, and a digital
processor/controller.

Title: PCS FlexBeamer® RF Repeater
System A &O Manual
Doc. No.: 913002500 Rev.: 00 Page: 18 of 84
The RAC interfaces to the Tx and Rx RF signals from the BTS via the Donor antenna and the BAU
has two serial ports for a local host computer RS-485 and remote control via a wireless modem for
diagnostics, (as an option) monitoring and control. The Active Bias-Ts in the RAC enable setting the
proper input power for the BEAMER® units and maintaining beam shaping using the DCA inside
the Active Bias-Ts. Up to 6 ACBTs , in any combination of Rx and Tx types can be assembled in
each RAC.
The RAC controller monitors the proper operation of the BEAMER® units of the BAU and
FLEXBEAMER® and enables real-time bi-directional communication between individual BEAMER®
unit and dedicated computer, via the RAC. The BEAMER® modules are constantly monitored and
controlled by the RAC unit.
Bi-directional communication with the BEAMER® is established through an FSK modulated
communication channel multiplexed on the Rx coaxial cable connecting the individual BEAMER® to
the RAC. The coaxial cable can be as long as 100 meters and have losses of up to 8db at 1850 to
1945MHz band.
The Uplink signal at 1850-1865 MHz runs on the same coaxial (Rx)cable with DC and the M&C from the
FLEXBEAMER®, but an isolation between the DC, M&C, and Uplink signals is high due to Bias-T
isolation.
The Down Link signal at 1930-1945 MHz runs on the same coaxial (Tx) cable together with the DC
voltage, but isolation between the DC voltage and Tx signals is high due to Bias-T isolation.
1.3.3. FLEXBEAMER®
Including:
• Linear P.A and LNA (Beamer®)
• Duplexer
• Combiners and Dividers
• Active Diversity Units for Up link or Down link or both Diversities (Optional).

(*L.A.- Lightning Arresters are an option)
The RF channels of the FLEXBEAMER® Repeater are built of Separate Down and Up links built of
Tx and Rx ABT and a BEAMER® module. The RAC is equipped with Four to Six Micro Rx ABTs
and Micro Tx ABTs. Each of the Micro ABTs can be one of several types, which differ in the
available gain from –4 db to +30db. In the above block diagram a full 95db Max. Gain on both channels
Repeater is presented.
The Bias-Ts serve Three purposes:
1. Supply DC voltage to the BEAMER® modules within the FLEXBEAMER® and the BAU.
2. Provide Gain controlled RF amplification stage for setting up the levels and compensate for the
cables losses possible RF losses and to maintain the necessary level of the transmitted or
received output power per sub-array.
3. Connect the BEAMER® modules Telemetry to the RAC controller via the superimposed FSK
link.

System A &O Manual
Doc. No.: 913002500 Rev.: 00 Page: 20 of 84
The gain of the Bias-Ts is defined according to the system design.
The Active Bias-T comprised of a boost amplifier and a digital controlled attenuator in order to adjust
the gain and enable a convenient interface to the Control features. The gain of the ABT assemblies is
Temperature Compensated.
The Rx ABTs are transparent to the FSK communication channel which enables the M&C
communication with the BEAMER® units in the FLEXBEAMER® and the BAU.
In this manual, Bias-Ts are also termed 'sub-array', since each Bias-T can serves an independent
portion of an array (i.e., Tx sub-array or Rx1 and Rx2 sub-arrays, which are all physically part of the
same array, but are logically independent entities).

2.2.2. System Measurement and Testing Conditions
• Live +24VDC with high current capability exists on the FLEXBEAMER® and BAU Coaxial
connections of the RAC. (These are the Tx ABT output and the Rx ABT input N-type
connectors at the RAC). Disconnect the AC or DC power to the RAC before any cable is
disconnected from the RAC, FLEXBEAMER® or BAU.
• Always use a DC block device connected to the measuring equipment input or output ports
(spectrum analyzer, power meter, or RF signal source), when measuring RAC performance.
• Do not apply more than +10dBm of RF input power to any RF port of the
FLEXBEAMER® Repeater system, or irreversible damage may occur.
• When measuring high power outputs, always verify that the equipment input port is capable for
handling the expected output power.
• When testing the units in lab or during field installation, always practice RF
radiation safety rules. It is not recommended for service or lab personnel to
work closer then 2 meters away from the FLEXBEAMER® Antenna surface
when operated at full RF power.
• During lab tests, with AC voltage applied to the RAC, do not use any PCS mobile transmitter
in a range of less than 10 meters from the FLEXBEAMER® unit. An unexpectedly high RF
power might appear at the output ports, which might in turn damage the measuring equipment
connected to that port.

2.3. BAU RAC and FLEXBEAMER® Installation Instructions
2.3.1. Sector Antenna Mounting
The Sector Antenna should be mounted on the top of the tower in order to achive best
coverage. The Customer should refer to existing Network Planning Tools or Celletra Technical
Support.
2.3.2. Donor Antenna Mounting
1. The mounting of the Donor antenna is pending the application and the location specific
parameters. The following guide lines for the Donor antenna mounting are recommendations
and the Customer should refer to existing Network Planning Tools or Celletra Technical
Support.:
• The Donor Antenna and the distribution antenna have Isolation in between them of at
least 10 db higher then the overall Repeater Gain. Since Gain is 35 to 95db , the
isolation should be 45 to 105 db. The Isolation is achieved by mounting the two
Antennas and the FLEXBEAMER® on opposite walls of a building or by mounting
both on the same tower but up to 10 meters vertically separation ( Isolation
dependent).
• For Maximum Repeater Coverage the Distribution FLEXBEAMER® antenna will be
mounted on Tower top while the Donor antenna will be mounted up to 10 meters
below the FLEXBEAMER® antenna.
2. The Donor antenna is a high Gain, high directivity, low side lobes Antenna and can be
one of several types and different vendors. Mount the Donor antenna following strictly the
manufacturer instructions.
3. Trim the Donor antenna Azimuth towards the Donor Base Station ,as per the process
of paragraph 3.2.1. Tighten and secure all screws per the Antenna Vendor instructions.

2.4. FLEXBEAMER® Installation Instructions
2.4.1. General Array Installation Instructions
We recommend using a 3”-4.5” diameter pole for the FLEXBEAMER® System installation. The
figures later in this section illustrate the installed FLEXBEAMER® units, showing the Tx and Rx
cables connections.
The RF coaxial cables connecting the BAU FLEXBEAMER® and the RAC can be of any 3/8” or ½”
diameter low loss type. These cables carry DC Current and RF signals from the RAC to the BAU and
FLEXBEAMER®. Since the FLEXBEAMER® include the Power amplifier and the LNA, the losses
on these cables can be high without affecting the overall performance. Thus , these cables can be as
long as 100 meters .
Sealing and weatherproofing of RF connector is of prime importance to assure good electrical contact
for many years, minimizing DC loss and passive RF inter-modulation effects. Thus, special care should
be taken with the RF connectors sealing and weatherproofing especially at the FLEXBEAMER® input
connectors that are exposed to extreme environmental conditions. Common sealing practice should be
used.
For sealing instructions, refer, for example, to Andrews weatherproofing recommendations with 3MTM
Cold ShrinkTM Weatherproofing Kit, or an equivalent sealing method.
Before installing the FLEXBEAMER® unit, note that each FLEXBEAMER® and BAU has a Tag
attached to it. After installation remove the tag keep it and log this info in the system manual book. This
tag carries the BEAMER® modules address.(This address is the serial number of each BEAMER®
unit as appears on the module label nearby the Rx connector).You will need these IDs later, for system
configuration setup.
2.4.2. Unpacking
Unpack the units and verify that there are no mechanical damages to any of the parts of the
FLEXBEAMER® units.

3.2.1. Donor Antenna Setting
1. Install the Repeater Donor Antenna and direct it optimally towards the Donor Sector.
2. Connect a Pilot Scanner to the Donor Antenna port for verifying that the requested sector is
relayed.
3. Record the maximum pilot signal level at the Donor Antenna terminal:
• Pilot PN Sequence Offset: _________
• Pilot power Pp _________[dBm]
• Pilot quality Ec/Io: ____________[db]
3.2.2. Repeater Down Link (DL) Gain Setting
The overall DL gain is settable in the rang of : 35dB to 95 dB by using the Remotely controlled
Attenuators of the BAU, FLEXBEAMER® and RAC. The following procedure will define the
optimum DL gain setting.
1. FLEXBEAMER® Gain Setting
Calculate the required Pilot Power according to the normal Site Planning Procedure to be
transmitted by the Repeater Array, according to the required coverage area, using the Network
planning tools. Since the maximum FLEXBEAMER® total power is 8 (2x4) watts, the maximum
allocated Pilot Power is 0.8 Watts (+29dBm) (20% of total power).
The FLEXBEAMER® Gain is settable over a 15.5 dB range , in 0.5 dB steps.
Denoting the required Pilot Power PP (= 2x0.8Watt) , the FLEXBEAMER® amplifier attenuator
should be set to:
FLEXBEAMER® Attenuation setting = 10 log 10 (PT max/10) =10 log 10 (PP/a.10)[dB]
……(1)
When PT max=Watt
Example: Assume your Network Planning tool requires the Max. Pilot Power
from the Distribution Array to be 1W. The FLEXBEAMER® attenuation should
be set according to (1) to the following Value:
FLEXBEAMER® Att. Value= 10 log10 (1/2.0)= -3.01 db ( rounded to 3db)

2. DL Low Power Chain Gain Setting
2.1 Calculating the Gain of the DL FLEXBEAMER® units: The Max. gain of
the DL amplifiers in the RAC is 95 db. This gain amplification is composed of 4 successive
amplifiers- The BAU LNA, DL Rx ABT, the DL Tx ABT and the FLEXBEAMER® Beamer
each contributes approximately 15dB of the total FLEXBEAMER® adjustable DL gain.
The total gain of the DL Amplifiers of the RAC should be set to the value which will bring the Pilot
Ec received at the Donor Antenna to the required value at the FLEXBEAMER® input. Thus the
DL Gain of the Repeater System should be set to the following value:
Total Gain of DL in Repeater = +Pp–P’p [dB]……………..(2)
Where Pp denotes the DL signal input to the Donor Antenna ………….(3.1.1).
Example:
If the Pp measured at the Donor antenna is –60dbm, the total required gain of
the DL amplifiers of the RAC is +27-(-60)=+87db ………..(2.1)
2.2 Dividing the Gain between the FLEXBEAMER® Repeater stages: After
calculating the total DL gain of the FLEXBEAMER® Repeater per equation (2), the gain should
be divided between the 4 stages of the DL FLEXBEAMER® Repeater chain. following are the
recommendations for doing that:
a. Start the process by setting all the DCA attenuation in the BAU and RAC to
15.5dB.
b. Start reducing the Attenuation from max. at the BAU first(which is the first
amplifier in the chain.
c. The second DCA to reduce the attenuation is the Rx ABT(second amplifier in the
chain).
d. The third DCA to be reduced it’s attenuation will be the Tx ABT.
Example:
According to the process in example (2.1) , one needs to have +71db gain out
of the +95 db available. Following the steps a-c, the DL Tx ABT attenuator is
set to 14dB attenuation, and the Rx ABT set to –10dB.
Note
The DL Main and Diversity EIRP’s should be equal in order to achieve the
maximum diversity gain.
Check by reducing the DL Diversity TX gain by –15.5 dB and check the
power (actual or through the BSM indication) of the Main channel.
Repeat the same procedure for the Diversity channel by reducing the Main TX
channel.

3.2.3. Repeater Up-Link (UL) Gain Setting
The overall UL gain is settable in the range of : 35dB to 95dB.
1. Set the FLEXBEAMER® LNA’s gain to +30 db ( DCA set to 0db attenuation).
2. Set the repeater UL RAC and BAU amplifiers (UL Rx ABT, UL Tx ABT, BAU P.A) gain to
minimum. This corresponds to a total UL gain of 50dB, including the FLEXBEAMER® amplifiers
3. Drive with a MS to the far – out border of the Repeater coverage area, and observe the
Mobile Tx Power (in test mode). Operate the repeater Remote Control SW to remotely control
the RAC UL amplifiers gain.
3.1 If the Mobile Tx Power is maximum (+23dBm), increase BAU UL PA Amplifier gain in
1dB steps until the Mobile Tx Power drops 2 dB bellow its maximum. If required , increase
the gain of the UL Rx ABT and than the gain of the UL Tx ABT.
3.2 If the Mobile Tx Power is less than 2db below its maximum (+23dBm), decrease the
FLEXBEAMER® Rx Gain in 1dB steps, Until the MS reaches the maximum of +21dbm
Mobile Tx Power.
*Note: This procedure guarantees a fade margin for UL of 2 db. In practice, the Operator should utilize
the required fade , according to the Site Planning rules. More margins are possible by further increasing
the UL repeater gain and observing the lower MS Tx Power. This should be tested in a drive tests
along the distribution side coverage border.
NOTE
The UL main and Diversity should be equalized: Measure power out of the BAU while attenuating the
main or diversity gain by –15.5 dB.
3.2.4. Repeater DL gain Fine Tuning
For optimum DL and UL balancing it is recommended to have additional fine tuning
procedure performed on the DL, after going through the previous processes.
1. Drive with a MS to the outskirt bounderies area of the Repeater coverage area ( the
same coverage border you have set for the UL) and observe the Mobile Ec/Io (in test
mode).
2. Operate the repeater Remote Control SW to control the FLEXBEAMER® System
DL amplifiers Chain.
3. If the Mobile Ec/Io is low or marginal ( Ec/Io = -14db ) increase RAC DL Amplifiers
( DL Rx ABT, DL Tx ABT) gain in 1dB steps until the Mobile Ec/Io is set to the
Operator’s network design desirable values.

5. NEW SOFTWARE DOWNLOAD GUIDE
5.1. Introduction
This chapter is a guide to loading program files to the RAC and BEAMER® via their Monitoring and
Control communication channels. This enables program upgrades in the field without dismantling the
equipment for that purpose.
The program loading is done from a PC when using the CELLETRA SOFTWARE DOWNLOADING
SYSTEM program, which is supplied by CELLETRA.
This chapter describes the loading process to the RAC and the BEAMER® using the CELLETRA
SOFTWARE DOWNLOADING SYSTEM.
5.2. Overview
5.2.1. Downloading Software to the RAC
In the software download process a new application program file is loaded to the RAC via the serial
communication channel or Wireless Modem and saved to the FLASH memory.
5.2.1.1. RAC Memory Configuration
The RAC controller includes two types of memories a FLASH memory and a RAM. The FLASH
memory includes the configuration parameters of the RAC (such as ID number, number of arrays,
failure conditions etc.) and the application program, which enables all the features of the RAC and
which is upgradeable.
The RAM is used for logging events into the log file during regular operation of the RAC, and for
receiving the new application program for the RAC during the download process. A third memory is

Title: BEAMER Array System-
Assembly and Operation Manual
Doc. No.: 913002500 Rev.: 00 Page: 68 of 84
located in the CPU component and includes the basic I/O program of the controller. This program
enables operation of the basic functions of the controller (such as serial communication and application
program loading) and cannot be modified. The memory size allocated for the application is 64 Kbytes.
Programming a new application program into the FLASH memory does not affect the RAC
configuration parameters.
5.2.1.2. RAC Download Operation Mode
Loading a program file to the RAC is enabled while the RAC operates in Download mode. The
operation mode of the RAC is changed by a command through the serial communication channel.
When the RAC operates in Download mode, no operational function is performed. (That means that it
does not provide monitoring and control of the BEAMER® s). The baud rate of the serial port
increases to 56K baud. That enables faster transmission of data packets to the RAC during the
download process. The RAC returns to operational mode (Auto) at the end of the loading process or if
there was no data transmission from the PC within a predefined time period .
5.2.1.3. File Transmission From PC to RAC
5.2.1.3.1. File Transmission
The program file is a HEX type file and the data is ASCII format. While loading the file to the RAC
the PC sends the file content line by line. The RAC reports TO the PC about reception quality. If
errors were detected the transmission will be stopped and an error message will be displayed. The PC
then restarts the transmission. The program is contained in files of 64 Kbytes. That is, if the program
size is greater than 64 Kbytes it will be packed in two files that are distinguished by their names.
5.2.1.3.2. File Name Format
The file name has the following format: IDUxxTVVV.Hyy
IDU RAC application header
Xx Not relevant for loader
T Application type (0,2,3=Celletra ICU/1=Micro ICU)
VVV Application version
Hyyy HEX: The program is packed in one HEX file
H00 and H01: The program is packed in two HEX files
Example: IDUck0102.h01
IDUck: Software application
0: Celletra version
102: Software version number
h01: High package of the hex file

5.2.2. Downloading Software to the BEAMER®
The Software download process enables loading of a new application program file for the BEAMER®
host processor and the DSP via the serial communication channel and saving it to the FLASH memory
in the BEAMER® .
5.2.2.1. BEAMER® Memory Configuration
The BEAMER® includes two processors a DSP and a HOST. The HOST processor is a general
purpose processor that is used for reporting BEAMER® status to the RAC via a FSK channel and for
initialization of the DSP.
The BEAMER® controller includes a FLASH memory that contains:
1. The configuration parameters of the BEAMER® (such as ID number, calibration tables etc.).
These parameters are not affected during the loading process.
2. The application program that enables all the features of the BEAMER® that can be replaced
by a new version.
3. The program and data files of the DSP that can be replaced by a new version.
The FLASH size contains two files of each program (two of HOST application, two program files for
the DSP, and two data files for the DSP). The required program files for operation are selected by the
user. The memory is arranged by pages (each page includes 128 bytes).
5.2.2.2. File transmission from PC to the BEAMER®
5.2.2.2.1. File Transmission
The new file is transmitted page by page from the PC to the RAC and from the RAC to the
BEAMER® . All files to be loaded are text files. The files contain a Header block, which is the
properties block, and the software to be loaded. When the load process is enabled, the baud rate of the
serial port (from PC to the RAC) increases up to 56K Baud. That enables faster transmission of data
packets to the RAC during the download process. The RAC reports the PC about reception quality
and if errors occurred, the transmission will be stopped and an error message will be displayed.
The RAC sends the data packets received from the PC to the BEAMER® and the BEAMER®
reports the RAC about reception quality. If errors were detected the transmission will be stopped and
an error message will be displayed
5.2.2.2.2. File Name Format for HOST
Files will be identified by the following suffix: name.hst
