1 GENERAL INFORMATION
The CDR1901 is a channel-selective CDMA repeater, designed to be fully
compliant with “Personal Base Station — Base Station Compatibility
Requirements for 1.8 to 2.0 GHz Code Division Multiple Access (CDMA)
Personal Communications Systems” ANSI J-STD-008 specifications. Separate
modules are used for each channel in both the transmit and receive directions.
Each module selects a channel in a given direction (transmit or receive) and
amplifies it. Standard output power is 2W (33 dBm) with an option for 4W (36
dBm).
The repeater is outfitted with one channel for each radio frequency path. The
fi'equency and amplification of each channel can be individually controlled. The
monitoring and control of the system occurs with a direct connection to a laptop
computer or via a wireline option for remote access by modern.

The CDR1901 consists of several modules: the duplexer, LNA (Low Noise Amplifier), Channel
Module (also known as Channelizer), and Power Amplifier. The reverse and forward directions
consist of similar modules.
General Information Ortel Corporation
MirrorCelI Select CDR1901 Manual
A receive diversity option is available for the repeater. (See Figure 2.) Receive
diversity improves the performance ofCDMA networks using repeaters. Two
antennas are deployed on the server side of the repeater, to allow for spatial
receive diversity. The signals from these antennas are combined, amplified,
filtered, and then sent to a single donor antenna. The improved signal that is sent
back to the donor site is accomplished without introducing additional noise or
delay to the system.
Other benefits of using receive diversity include a reduced Er, / No, on an average
of ldB, and reduced mobile transmit power of 1 — 2 dB. The reduced Er, / N0
improves capacity of the donor site and minimizes cell site shrinkage. Reduced
mobile transmit power has the benefits of increased phone battery life and
increased coverage area for the repeater.

When using receive diversity, two sewer antennas are needed. The modules are similar to those in
the standard CDRl901, with the addition of a bandpass filter on the receive diversity antenna and
a low noise diversity module.
The primary frequency stabilization for the CDR1901 CDMA repeater is provided
by the 10 MHZ temperature stabilized crystal oscillator, which provides a
temperature compensated basic reference frequency for the PLL that provides the
local oscillator frequency. The basic settable frequency accuracy is 5 ppm. All
internally generated frequencies are locked to this basic oscillator. The same LO

frequency is used for both the upconvener and downconverter, ensuring no
difference in the input and output frequencies.
An aluminum case houses the repeater. Cooling fins for the amplifier are located
on the rear of the unit. The choice of aluminum as the case material gives a
lightweight design with good heat conduction and weatherproof protection. The
housing conforms to NEMA 3R/ IP32 standards.
The transmit and receive antenna ports are 7/16” standard, with the option of N-
type connectors, located on the underside of the repeater. The external
connections on the bottom of the repeater are protected from unauthorized access
with a cover, which can be opened only from the inside of the repeater.

The PCS frequencies are divided into six different groups called bands. These
bands are labeled A, B, C, D, E, and F. Each band consists of two sets of
frequencies: one set for transmit (forward) and one for receive (reverse) The
transmit frequencies range fi'om 1850 MHz — 1910 MHz; receive frequencies
range from 1930 MHZ — 1990 MHz. The order of the bands (in ascending
frequency) is A D B E F C. These frequencies are divided as follows.

4.2 Channel Plan
The frequencies for each band are organized by channel numbers. Each channel
number consists of a pair of frequencies: one frequency for the forward direction
and one for the reverse direction. The frequencies corresponding to a particular
channel can be calculated using the formulas in the following table.
. Channels Channel Number Center Frequency (MHz)

Ortel Corporation Attenuation Control of the Amplifier
MirrorCeII Select CDR1901 Manual
5 ATTENUATION CONTROL OF THE AMPLIFIER
Rev. F
The Min-orCell Select CDMA repeater offers 30dB of user-settable attenuation to
customize the desired output of the repeater. The amplifier can be attenuated in
ZdB steps, from OdB to 30dB. Ortel recommends that you start with 30dB of
attenuation and slowly decrease attenuation, thereby increasing output power, in
order to ensure the repeater transmits only the desired amount, and not more. This
will help to reduce interference caused by too much output power
The following table is a guideline for setting the attenuation.
' ids)
36dBm Output
Figure 12. Attenuation Control of the Amplifier.
The gain of the repeater can be set via the amount of attenuation added to the signal path. Note
that the gain of the standard ZW (33dBm) repeater is SSdB while the gain of the 4W (36dBm)
repeater is 88dB.

MirrorCelI Select CDR1901 Manual
6 DESCRIPTION OF THE CONTROL MODULE
6.1
General
The repeater is equipped with a status & control module, which allows the
monitoring and control of various parameters such as channel number,
attenuation, temperature, status of door, etc., either with a local terminal or via
OMC The communication interface between the local terminal and the control
module is set up as a self-explanatory menu for simple manual control and
monitoring This way, the parameters can be easily read off of and set up from the
display.
6.2 Settings
The physical interface to the control module consists of a VT-lOO series terminal
connected to the repeateri Specifically, you will need a laptop computer with a
terminal emulation program, such as ProComm or HyperTerrninal, connected to
the repeater via a DB9 straight-through serial cable with a male connector for the
repeater side and a female connector to hook up to the computer‘s R5232 serial
port.
The communication format must be set in the terminal emulation program:
9600 baud
8 bit
1 stop bit
No parity
No flow control (flow control = none)
6.3 Login via Local Maintenance Terminal (LMT)
When the PC is connected to the repeater, the login sequence is activated by user-
input keystrokes. (See Section 7.6 in the Installation chapter for greater detail.)
The login sequence begins by asking for Usemame and Password. Different user
accounts have different authorities. The default login parameters are:
User Name Password ; Authority
USERNAMl PASSWRD1 read/write
USERNAM2 PASSWRD2 read/write
USERNAM3 PASSWRDS read only

SET PWD2 Alhambra 
For more information, see section 6.10.3.
The control module logs the number of failed login attempts. If this number
exceeds the user—defined maximum (ILA, default = 8), then fiiture login attempts
will be blocked. The false login count is decreased by one each hour. This means

6.11 Alarms and Alarm Configuration
6.11.1 Overview
The MirrorCell Select CDMA repeater can send alarms to an Operations and
Maintenance Center or to the MirrorCell Element Manager (MEM), both referred
to as the OMC in this document, via a DataCall (modem connection). For each
alarm sent, an end of alarm will also be sent when the end of alarm condition is
detected. This does not include VLI, LGO, CLR, and ILI alarms. By default, the
repeater requires an acknowledgement of each alarm sent. When using SMS, all
letters must be capitalized.
Each alarm source can be individually configured. The software has the capability
to enable or disable the requirement to aclmowledge particular alarms (not
including VLI, LGO, CLR, and ILI alarms), and the capability to configure
different threshold for particular alarms. In addition, if a particular alarm
condition arises which causes the alarm to toggle between OK and ERROR, the
sofiware has the capability to adjust the Minimum Alarm Repetition (MAR) time
and the Ma‘kimum Number of Repetitions (MNR). This will keep the repeater
from blocking the communication interface with a series of Alam'i/End of Alarm
notifications (See section 6,117.2, “Minimum Alarm Repetition Time” for more
information on this feature.)

6.11.7.2 Minimum Alarm Repetition Time
This command has been introduced for the case where an alarm is toggling
between 0K and ERROR. In this state, the repeater should not continuously call
the OMC with the new alarm detected for the same fault condition and potentially
block the communication between the repeater and the OMC. Typically the MAR
should be set to a minimum of two or three times the amount it takes for the
repeater to dial up and report the alarm. MAR is expressed in minutes, and the
default value is 3.
Note that the first error will always be detected within the normal threshold time
Only the repeated alarms will be blocked. If numerous alarms are received at the
OMC, the operator must be able to send a message to disable the particular alarm
at the repeater until service of the repeater can be performed.
For example, to set Minimum Alarm Repetition:
SET MAR 5 
This will set the alarm repetition time to 5 minutes.

7.2 Site Selection
Site selection for the repeater is one of the most critical decisions affecting the
overall performance of the repeater system. A repeater must be located where it
can receive a sufficient signal from the donor site in order to maximize the
repeater’s performance. For the 33dBm output repeater, an input signal strength at
the donor input connector (afier the donor antenna and coax cable) of greater than
or equal to —52dBm is required for a 33dBm output: -52dBm + 85dB gain =
33dBm. For the 36dBm output repeater, an input signal strength of greater than or
equal to «SZdBm is required for a 36dBm output: -52dBm + 88dB gain = 36dBm,
Examples of repeater and accompanying antenna locations include, but are not
limited to:
- the roof of a building adjacent to the affected area with the antennas
mounted to the penthouse or building sides
0 the top of a bill that is obstructing the donor site’s coverage, with the
antennas pipe-mounted at ground level
0 a water tower with antennas mounted at the top
- an existing utility pole, with equipment and antennas mounted below
any existing power lines
o a newly installed pole or tower.
For more detailed information on site selection, as well as antenna selection and
placement, please see Ortel‘s Application Note: “Integrating MirrorCell Select
Repeaters into a CDMA Networ
Rev. F 7-1
Installation of the CDR1901 Ortel Corporation
MirrorCeII Select CDR1901 Manual
7.3 Antenna Selection
Proper selection of the repeater’s donor and sewer antennas is crucial in designing
the repeater system. Good antenna characteristics help to provide proper isolation
between the server and donor antermas, which helps to prevent feedback.
The donor antenna selected for use with a CDRlQOl is critical in the design of a
properly functioning repeater system. Since in CDMA systems all of the base
stations transmit the same frequency, the donor antenna selected must be capable
of receiving only the desired base station. Microwave dish antennas with vertical
and horizontal beamwidths of less than 15° are ideal candidates for the donor
antenna. Microwave dish antermas also provide the recommended fi'ont-to-back
ratio of greater than or equal to 25dB to help achieve the required antenna
isolation‘
The server antenna should provide the desired coverage and also provide the
recommended the recommended front~to~back ratio of 25dB. Many different
types of antennas will work as a server, such as panel antennas, Yagi antennas,
and, for indoor applications, Omni-directional antennas.
The isolation between antennas must be at least lOdB greater than the gain setting
of the repeater or the repeater could go into oscillation. Specific ways to achieve
proper isolation include:
0 using high gain, directional antennas with good front-to-back ratios
QZSdB)
- pointing the donor and server antennas opposite each other; ie, at 180°
from each other
0 physical separation of the repeater’s donor and server antennas
- external shielding, such as wire mesh or a grounded metal plane.
Antenna isolation limits the amount of gain to which the repeater should be set.
Therefore, if isolation is less than 95dB, the repeater cannot be set to the
maximum of 85dB, in the 33dBm-output model For the 36dBm-output model,
and isolation is at least 98dB is required to use the fill 88dB of gain.
The table in Figure 14 is a guideline as to how far apart antennas need to be
placed in order to achieve the desired isolation. These figures assume the donor
and server antennas are pointing 180° apart and are based on the following
formula
7-2
Rev. F
Ortel Corporation Installation of the CDR1901
MirrorCelI Select CDR1901 Manual
Vertical separation: I(dB) = Z8 + 40 log (D/k)
Horizontal separation: I(dB) = 22 + 20 log (D/lt) — (G, + Gs)
l= Isolation (dB)
D = Distance between donor and sewer antennas (feet)
A. = Wavelength (feet)
Gd = Gain of donor antenna in direction of sewer antenna
G9 = Gain of server antenna in direction of donor antenna
(valid for Gd, Gs < 10dB)
Note that this table is only a guideline and does not substitute for measuring the
isolation. See section 7.4.2 for procedures to measure isolation.
Figure 14. Vertical and Horizontal Antenna Isolation at 1900 lVH-h.
Antenna isolation increases the further apart the antennas are mounted. As this table shows,
vertical separation provides better isolation than horizontal separation
7.4 Antenna Mounting
7i4.1 Donor Antenna
Use the following steps to mount the donor antenna.
1. Mount donor antenna at initially desired location.
2. Measure the received signal strength from the donor site. The amount
of power the repeater can produce is dependent on this signal level.
Note whether the donor is loaded or unloaded, as this will affect the
amount of power needed. The tables in Figures 15 and 16 show
received signal strength measured alter the donor antenna into the
repeater when using the full gain of the repeater.
Rev. F 7-3
Installation of the CDR1901 Ortel Corporation
MirrorCeII Select CDR1901 Manual
Figure 15. Received Signal Strength vs. Output Power for Standard Repeater.
The output of the repeater is dependent upon the received signal strength at the donor antenna port
and the amount of gain used. For example, when the repeater’s full 85dB of gain is used, with a
received signal strength of—65dBm, the maximum output the repeater can provide is ZOdBm,
Figure 16. Received Signal Strength vs. Output Power for 36dBm Repeater.
The output of the repeater is dependent upon the received signal strength at the donor antenna port
and the amount of gain used For example, when the repeater’s full 88dB of gain is used, with a
received signal strength of —65dBm, the maximum output the repeater can provide is 23dBm,
3. If a greater signal strength is needed, try raising the donor antenna’s
height, or use a higher gain antenna, if possible.
4. Measure the pilot tone strength received atter the donor antenna and
verify that the proper base station sector is being received. The pilot
tone of the desired base station should he at least 15dB higher than any
of the other received pilot tones. If this is not the case, the donor
antenna should be adjusted until the desired pilot tone is lSdB greater
than any other received pilot tones. (Note that this requires a CDMA
signal measurement device.)
7.4.2 Server Antenna Mounting and Isolation Measurements
Isolation measurements should be taken to ensure proper operation of the
repeater. Measurement of isolation can be accomplished easily by following the
procedures, as illustrated in Figure 17.

Ortel Corporation

SIGNAL
GENERATOR
1. Mount server and donor antennas at initially chosen location to obtain
desired coverage.
2. Inject a known signal within the bandwidth of operation into the
donor antenna. An unused channel within the band should be used.
The signal should be at least 1W in order to allow for an accurate
measurement of isolation. The repeater and a low-power signal
generator can be used in series to generate a signal of sufficient
strength. The repeater will 55dB — 85dB of gain (or 58dB — 88dB for
the 36dB-output repeater), depending upon how much attenuation is
added to the repeater.
3. Connect a signal measurement device, such as a spectrum analyzer, to
the server antenna. Measure the received signal level. The difference
between the signal input to the donor antenna and the received signal
measured after the server antenna is the antenna isolation. (Note that
the gain of the antenna is not used in the calculation.)

MirrorCeIl Select CDR1901 Manual
4. The repeater gain can be set to at least lOdB below the figured
measured above. (The antenna isolation must be at least lOdB greater
than the repeater gain.) For example, if the antenna isolation measured
is 90dB, the repeater gain should be set for no more than 80dB.
5. If isolation is not great enough (is, if more gain is required), you can
try either of the following:
a. Separate the antennas by a greater distance. (See the tables in
Figures 15 and 16 for separation distances with expected isolation.)
b. Mount some type of external shielding between the antennas, such
as a mesh screen, an ice shield, or grounded metal plate‘
7.5 Repeater Mounting and Installation
The following recommendations should be adhered to for enhanced repeater
performance.
1. The repeater comes standard with wall mount brackets as shown in
Figure 18. The brackets attach to the repeater with eight M8x1.25
thread bolt screws, included in the shipment.
2. The repeater should be mounted so the heatsink avoids direct sunlight.
This will help improve the lifetime of the repeater.
3. Mount the repeater upright so that the connectors are on the underside.
This will help prevent a buildup of moisture inside the repeater.
4. The repeater is equipped with 7/16" DIN (or N-type as an option)
antenna connectors. Connectors are located at the bottom of the unit. A
protective cover is included with the repeater to prevent unauthorized
access to the connectors. The cover can be installed or removed only
from the inside of the unit.
5. Ensure that adequate room has been allocated for the bending radius of
the cables. Refer to the cable manufacturer’s specifications for the
allowable cable-bend radius
6. Ensure that adequate room is allowed for the opening and closing of
the repeater door. See Figure 18 for dimensions of the repeater.

9. Set the attenuation levels of O — 30dB as follows. For the uplink (reverse path)
attenuation in channel 1:
SET ATU X YY 
X = Channel 1 within the repeater
YY = Uplink attenuation level for channel 1.
SET ATU 1 10 
sets the reverse attenuation level for the repeater’s channel 1 to 10118. Now,
the repeater‘s reverse gain will be 85 — 10 = 75dB, for the standard repeater.
Revr F

For the downlink (forward path) attenuation in channel 1:
SET ATD X YY 
X = Channel 1 within the repeater
YY = Downlink attenuation level for channel 1.
SET ATD 1 10 
sets the forward path attenuation level for the repeater’s channel 1 to lOdB.
Thus, the repeater’s forward path gain will be SSdB — lOdB = 75dB.

Set the peak levels at which the repeater should transmit in the uplink
(reverse) and downlink (forward) directions. Forward peak levels for the
standard repeater are 27dBm, 30dBm, and 33dBm. Forward peak levels for
the 36dBm repeater are 30dBm, 33dBm, and 36dBm. Reverse peak levels for
both the standard and 36dBm repeaters are 27dBrn, 30dBm, and 33dBrn. Note
that due to low output power from the mobile, reverse path power rarely
exceeds ZOdBml
To set the peak level in the reverse path:
SET LVU X YY 
X = Repeaters channel 1
YY = Reverse maximum transmit level.

To set the peak level in the forward path:
SET LVD X YY 
X = Repeater's channel 1
YY = Forward maximum transmit level.
SET LVD 1 30 
Typing STATUS will show that the channel number and gain settings have
been changed. The repeater now should be configured for operation.
1 1. The repeater should be turned off before connecting it to the antennas. Once
connected, the repeater can be turned on The output power of the repeater
should be monitored on the test port. The test ports are 30dB couplers; thus if
an output power of 33dBrn (2W) is desired, the power measured at the test
port should be 3dBm. The attenuation of the repeater should be decreased
until the desired output power is achieved.
7.7 Optimization
Now that the repeater is providing the desired output power, the system needs to
be optimized. The search window and neighbor lists of the donor base station
should be reviewed. Verify the pilot search window parameters are properly set to
compensate for filter group delays in the repeater. The repeater uses highly
selective Surface Acoustic Wave (SAW) filters, which have a group delay of 11
microseconds. Since the propagation delay of free space is 5.4 microseconds per
mile, the delay is “equivalent” to two miles of free space propagation.
The search window of the donor base station may need to be increased depending
on the distance from the repeater to the donor base station. For example, if the
repeater is 3 miles from the donor base station, and the desired coverage area of
the repeater is 2 miles (for a total of 5 miles):
(5 miles) * (5.4 “sec/mile) + 11 psec (delay in the repeater) = 38 usec
The donor BTS pilot search window would need to be at least 38 microseconds
for call activation to take place.

The neighbor lists of the donor base station and the base stations surrounding the
area served by the repeater need to be adjusted For example, in FigLre 21 a
repeater extends the coverage of BTS] to a new area. BTSl is new neighbors
with BTS4 and BTSS, whereas without the repeater, BTS] is neighbors with just
BTSZ and BTS}. Thus BTS4 and BTSS must be added to BTSl’s neighbor list,
and BTS] must be added to BTS4’s and BTSS’s neighbor lists. A drive test of the
coverage area should be performed to verify the final setup.

Neighbor list changes may need to be implemented when adding a repeater into a system.
