General Repeater Information
The Repeater Technologies Over-theAlr 19000 1-chnnne16.3 Watt Network Repeater”
(hereafter referred to as the OMQOOC NFl or the repeater) is a [oi-directional. on-frequency.
over-the-air RF channelized Hepeaterfor CDMA.
The OA19000 NR extends the coverage of PCS base stations. it is available with an optional
diversity receive feature, which improves base station receive performance in high-mobility
applications.
The repeater receives signals from 9 Base Transceiver Station (BTS) and re-transmits them to a
subscriber Personal Communications Service (PCS) telephone; likewise, the repeater receives
signals from a subscriber telephone and re-transmits them to the BTS. Repeaters significantly
improve coverage in areas with weak signal reception or transmission,
The OA1900C NR is designed for indoor or outdoor installation and can be either wall or pole
mounted. The unit’s compact cabinet simplifies installation. while its aesthetically acceptable
design allows it to be zoned easily in many locations. The repeater only requires initialization
Also, as a field-replaceable unit, it requires no component-level repair.

Functional Description
The OA1900C NR uses a unique Intermediate Frequency (IF) filtering design to achieve a high
degree of selectivity. It also uses a common local oscillator tor up-and down-conversion to prevent
frequency conversion error,
The RepeaterNet Craft software is the configuration management and alarm monitoring interlace
for the OA19000 NR. The repeater has two communication (COM) ports lor RepeaterNet
connections—a serial port lor direct, laptop connections and a modem port for remote
connections.
An Automatic Level Control (ALC) circuit protects the repeater‘s circuitry lrom potentially damaging
high input levels and minimizes the generation of Intennodulation Distortion (IMD) in the transmit
power amplifier. The lollowing figure is a block diagram of the 0A19OOC NH.
The signal processing flow through the repeater in the lorwerd direction (BTS to mobile) is similar
to the tlow in the reverse direction (mobile to BTS).

Signal flow is as follows:
1. The received signal from the BTS antenna enters the repeater through the cabinetmounted
Type N (l) connector, and feeds to a branching circulator and a diplexer filter.
The Signal then is amplified by an LNA and down-convened to an Intermediate Frequency (IF).
After being filtered by Surface Acoustic Wave (SAW) filters, the output signal is lip-converted
and precisely restored to the original RF frequency by using the same Local Oscillator (L0) as
the one in the down-converter.
4. The signal then passes through a bandpass fllter to eliminate unwanted sldebands and L0
leakage.
5, The transmit power amplifier further amplifies the signal to achieve final transmit Radio
Frequency (RF) power levels. See Table 2 for specific information about power output.
6. The signal finally routes through the output diplexer to the mobile antenna. (The diplexers
permit use of common antennas for both transmit and receive signals while effectively
separating the receive band from the transmit band.)

Mounting and Connecting Antennas
Antenna size is specified on the Path Data Sheet—do not install antennas of a different size. The
size of antenna coaxial cabling for an application depends upon a number ol system parameters
lnC|Udlflg. but not limited to:
5 Required signal output
a Antenna gain
3 Transmission line length
The allowable path loss for antenna cabling. and therefore the size of the cabling. is specified on
the Path Data Sheet for the project. Do not install cabling of a different size than specified on the
Path Data Sheet.
_____________.__—————————
NOTES:
= As a signal passes through coaxial cable, the strength oi that signal decreases. This loss of
signal strength, known as path loss, decreases as the diameter of the cable increases.
: Check the diameter oi the coaxial cable before installing. It the cable is more than Pé-inch
(1.3 cm) in diameter, attach a coaxial jumper assembly (which you must supply) to the
connector on the antenna cable. Make the jumper assembly of vxfi-inch (1.3 cm) coaxial
cabling and use its DIN or a Type N connector, one male and one female.
CA 19000 NR Operations Manual Chapter 3. Mounting the Repeater— 16
To install coaxial cabling lo the Base and Mobile antennas:
1. Make sure the coaxial cable is long enough to reach the OM 90°C NR installation site.
2, Install either a 7Ii: DlN (rn) or a Type N (m) connector on the coaxial cable,
3. Connect cables to the Base and Mobile antennas,
CAUTION: If a coaxial cable is larger than Vz-inch (1.3 cm) in diameter, do not connect I!
directly to an antenna part on the repeater, as possible damage could result.
Using a coaxial jumper assembly reduces strain on equipment connectors,
4. Having read the above caution, connect the other end of the antenna cables to the appropriate
ports labeled on the bottom ol the repeater.
You can mount the OMch NE on a pole or on the wall of a building. The OA1900¢ NR is

Pole Mounting
Repeater Technologies offers optional pole mounting equipment for the OA1SOOC NFt, available
when ordering the OA19000 NR.
Pole installation reqwres the following materials:
3 Pole mounting kit (available lrom Repeater Technologies)
r.» Banding kit (purchased separately; available lrom McMaster—Carr) it you are mounting the
repeater on a concrete or metal pole
: Class A - Pole Line Hardware it you are bolting the Pole Mounting Bracket to a wood pole
The Pole Mounting Channel is designed so that the repeater is “squarely" mounted on the pole and
does not wobble.
It a concrete pole is used as the mounting structure, typically it is not prudent to try and drill a hole
through its center. Similarly, because metal poles may have cable run up the center, drilling is not
recommended. Banding is prelerred over drilling. However. wood telephone-type poles are
forgiving and the pole—mounting channel can be easily iastened to the pole with lag screws or
through-pole bolts.

Chapter 5. Orienting and Isolating Antennas
Preliminary Antenna Orientation
With the antennas mounted, coaxial cables installed, and the Repeater power OFF, antenna
orientation can begin.
BTS Antenna
To orient the BTS antenna:
1. Disconnect the coaxial cable from the donor BTS antenna at the antenna port on the repeater.
2. Connect the service monitor to the cable lrom the BTS receiving antenna.
3. While monitoring the control channel assigned to the donor BTS, position the BTS antenna to
maximize the FlSL (Received Signal Level).
4. Analyze the signal to ensure it is correct.
NOTE: Record the level of the control channel and other active carriers from the donor BTS for
later reference,
If the RSL is less than Maximum RF Output Power Level minus Maximum Gain, lull repeater
output power may not be reached when installed, See Table 4 on page 5 tor FlF output and
maximum gain levels. To correct the problem, repoSition the antenna. change the mounting height
at the antenna. or use an antenna wtth greater gain to reach the required FtSL.
Mobile Antenna
The Mobile service antenna can only be bore-sighted (aimed by eye) at this time. Aim the antenna
as closely as possible to its iinal posnion. Accuracy is important because the antenna position
altects antenna isolation.
Antenna Fundamentals
An antenna is a transducer between electromagnetic waves in space and voltages or currents in a
transmission line. When transmitting, the antenna convene electrical signals into radio waves: a
receiving antenna reverses the process and translorms radio waves back into electrical signals.
All antennas are directional, transmitting more power in some directions than others. The direction
oi maximum transmission or reception is called the borecighl direction. The directional
properties 01 an antenna are described by its radiation pattern. a pictorial representation of relative
radiated power versus direction. Radiation patterns exhibit a lobe structure in which the largest
lobe in three-dimensional space constitutes the beam through which the antenna radiates or
receives most of its power.
The tendency of the antenna to concentrate its radiated power is called gain. The angular width of
the main beam measured between the half-power points is called the beamwldth of the antenna.
Beamwidth and gain vary inversely with each other; a highgain antenna has a narrow beamwidth
and vice versa. Gain is proportional to the physical area oi an antenna expressed in square
wavelengths.
Radiation pattern lobes other than the main beam are called sldelobes. The higher the sidelobe
level. the more likely an antenna is to interfere with or be interlered with by a receiver in the
direction oi the largest sidelobe.
CA 19006 NR Operations Manual Chapter 5. Orienting and Isolating Antennas — 33
An antenna has an operating frequency—the frequency at which the antenna exhibits optimum
perlormance—and a bendwldth—the lrequency range over which the antenna impedance and
radiation pattern remain within some required tolerance.
Antenna Isolation
To prevent oscillation or severe passband distortion. the antennas must have a port-to-port
isolation equal to 15 dB plus the OM 90°C NH active galnt For example, an 0A1900C NR set
fora maxtmum available gem of 95 dB requires a minimum antenna isolation of 110 dB (95 dB +
15 dB) tor proper operation.
Be aware that the motion ol objects near the antennas can change the isolation significantly. It
possible, pertorrn tests with expected objects present to ensure the isolation does not drop below
minimum required levels.
To measure the isolation:
1. Disconnect both antenna signal cables from the antenna ports on the repeater.
2. Inject a signal into one at the antennas and measure the power level ol that signal at the other
antenna. The dilemma in power levels (measured in dB) between the injected signal and the
measured signal is the isolation of the antennas.
NOTE: Because antennas are not yet connected to the repeater, isolation is obtained through the
air.
3. Repeat the test at several lrequencies across the Forward and Reverse passband. confirming
that minimum antenna isolation is met at all applicable lrequencies.
4. It isolation is not met. try repositioning the antennas or adding intervening shielding, and
measure again,
The following method can be used to estimate antenna isolation (referenced to dBd), During
installation, always rely upon actual measurements, not estimated data.

8. Repeat tor Reverse PA.
NOTE: Forward transmit power increases as the orientation at the Donor antenna is optimized.
Make any requrred adjustments to the Donor antenna lacrng the Cell Site to maximize
Forward power output
“h“
Adjusting for Hot Input Levels
The OA‘lQOOC NR has an adjustable gain range of 30 dB with upper and lower limits defined by
the PA level ol the repeater. In some applications, however. not input levels require that antenna
gain be set below the lower limit at this range.
To set antenna gain below the lower limit of the operating range:
1. Choose a fixed attenuator pad that is able to set the gain to a level about 5 dB lower than what
is required.
2. Install the attenuator pad at the antenna port.
3. Make the final upward gain adjustment with FtepeaterNet.
NOTE: If an attenuatarpad is inserted in this manner, FlepeatarNet cannot show the actual
antenna gain. For example, it the Attenuatorpad reduces gain by 5 dB, the system gain is
actually 5 dB lower than the setting shown on the FA Properties screen.

Internal Backup Battery
The 0A19000 NR includes an internal backup battery to provide limited back-up power lor the
ACU and, ii applicable. the cell phone and internal modern. In the event oi a loss oi system power,
the internal battery provides power tor the repeater to call out and report the iailure, and to save
the Alarm and Event Log. The length at time that the internal battery provides power depends upon
Repeater configuration and environmental conditions (such as temperature).

'Vaiues are estimates only: aclua/ battery life may vary. Estimates assume a lully charged battery,
adverse envrronmental conditions, and a 600 mWAMPS cellphone.
System power charges the internal battery during normal operation. Note that the internal banery
has a low voltage cut-oif to allow tor a lull recharge when power is restored.
It a power outage lasts longer than the operational limit at the internal battery, the modern cannot
send or receive calls, and Alarm and Event Log data is lost. Save the Alarm and Event Log when
the repeater calls out to report a system power iallure~see "The System Menu” in RepealerNet

NOTES:
= The lntemal battery does not provide power lor HF transmission during a primary power
outage. Service is interrupted during a loss ol primary system power.
: The battery should be replaced on a 3-year cycle to allow for non-rial aging. wear, and
environmental deterioration.

antenna, a hot tone—for example,
a receive signal above -40 dBm—
is produced. Too hot a tone can
over-modulate a system and force
