PRODUCT DESCRIPTION
Cellular Specialties, Inc. developed the Model 610amps In-Building Amplifier (IBA) for use in enclosed
structures where sufficient signal from local cell sites to operate cell phones was unavailable within the
building. It is, of course, necessary that sufficient signal be available on the roof of the structure. The
IBA is connected to an external antenna, usually on the roof, and to one or more internal antennas
placed strategically throughout the area where phone service is desired.
The external antenna is an omni-directional antenna, used when the building is located in close
proximity to one or more cell sites. Internal antennas are usually omni-directional although various other
types may be used for certain installations. The IBA amplifies both the "uplink" (phone to tower) and
"downlink" (tower to phone) signals thus facilitating communications to and from the local cell site
There are seven amplification stages on the downlink and seven on the uplink for a total of +85dB
nominal gain for each link. (see Figure 2.1) Both links have manual gain control settings accessed
through DIP switches on the top cover plus an AGC control for both the uplink and downlink. There are
also LED indicators on the top cover for power on, transmitter on, uplink overload and downlink
overload.
An automatic amplifier safety shutdown circuit is also present that will disable the transmitters for ten
seconds should the uplink or downlink overloads be reached to prevent excessive intermodulation and
oscillation.

INSTALLATION
Pre-installation Survey
Note:
The Installer should refer to the Safety Precautions, in the
following section, for proper antenna selection and installation
A pre-installation survey should be performed prior to commitment to installation. Measurement of
Received Signal Strength Indication (RSSI) should be recorded throughout the building in all areas
where cell phone coverage is desired. RSSI levels around the exterior of the building as well as on the
rooftop or as close to the point where the exterior antenna will be installed should also be recorded.
RSSI readings at the position where the outside antenna will be installed should be greater than –80
dBm. (E.g. –75dBm) Successful installations may be made with lower readings in some cases.
MANUAL610AMPS OMNI
WARNING!
AMPLIFIER DAMAGE WILL OCCUR IF A HANDSET IS
CONNECTED DIRECTLY TO THE IBA OR THE COAX THAT
LEADS TO THE IBA.
The location of the IBA and the interior antennas should be determined through the
use of floor plans of the building in which the system is to be installed. It is important
to locate the IBA at a central location and try to keep the coax runs from the amplifier
to the antennas as short as possible. A maximum length of 150 feet is suggested
although longer runs might be accommodated. This assumes that a coax with loss at
800 MHz of approximately 3.5 dB per 100 feet is used. The coax used should be a
nominal RG-8 type with a flame retardant rating except when installed in space
where moving air (heating and/or cooling) exists. In which case the coax must be
“plenum” rated. For long runs that exceed 150 feet, the use of low loss ½” coax is
desirable. Of primary concern is the isolation between the outside antenna and the
inside antennas.
Important note: A high degree of isolation must be afforded in order to prevent
any re-generative feedback in the system. Feedback of this nature causes the
amplifier to emit a continuous signal of maximum amplitude and could, in
some cases, interfere with normal operation of the cell site. This isolation
should be in the order of 70 dB and is usually obtained by mounting the
outside antenna away from the edges of the roof. The use of window mounts
or other non-rooftop mountings should be avoided.
SAFETY PRECAUTIONS
For INDOOR use, an Omni-Directional Antenna with a maximum gain of 3dBi is
authorized for use with this unit.
Inside antennas must be positioned to observe minimum separation of 20 cm.
(~ 8 in.) from all users and bystanders. For the protection of personnel working
in the vicinity of inside (downlink) antennas, the following guidelines for
minimum distances between the human body and the antenna must be
observed.
The installation of an INDOOR antenna must be such that, under normal
conditions, all personnel cannot come within 20 cm. (~ 8.0 in.) from any
inside antenna. Exceeding this minimum separation will ensure that the
employee or bystander does not receive RF-exposure beyond the
Maximum Permissible Exposure according to section 1.1310 i.e. limits for
General Population/Uncontrolled Exposure.
MANUAL610AMPS OMNI
!
For OUTDOOR use, an Omni-Directional Antenna with a maximum gain of 3dBi
is authorized for use with this unit.
Outside antennas must be positioned to observe minimum separation of 20
cm. (~ 8 in.) from all users and bystanders. For the protection of personnel
working in the vicinity of outside (uplink) antennas, the following guidelines for
minimum distances between the human body and the antenna must be
observed.
The installation of an OUTDOOR antenna must be such that, under normal
conditions, all personnel cannot come within 20 cm. (~ 8 in.) from the
outside antenna. Exceeding this minimum separation will ensure that the
worker or bystander does not receive RF-exposure beyond the Maximum
Permissible Exposure according to section 1.1310 i.e. limits for General
Population/Uncontrolled Exposure.
Physical Installation
The coaxial cable discussed above should be pulled from the rooftop location to the
space designated for the amplifier installation. Additional coax should be pulled from
the amplifier to where power splitters are located and thus to the position designated
for the Omni-directional antennas. Usually this is accomplished by using existing
cableways and running the cable above suspended ceilings. In many cases the
Omni-directional antennas can be located above the suspended ceilings however,
when this is not possible, alternatives such as ceiling or wall mounted antennas may
be used.
When mounting the amplifier, take care to avoid areas of high heat or extreme cold.
In general, do not place the unit on or near the top of high ceilings, by heaters or in
cold storage areas.

AMPLIFER ADJUSTMENT
In most cases the IBA will need very little adjustment. After connecting the coax and
powering up the IBA, the signal levels within the previously surveyed areas should be
checked for adequate RSSI and Signal Quality Equivalent (SQE) levels.
Measurements should be made at the perimeter of the building both inside and
outside. It is important that the RSSI levels measured outside the building remain
close to those measured prior to installation of the IBA.
Both the uplink and downlink overload indicators should remain off. If either indicator
is illuminated, the gain of the appropriate link should be reduced.
If the gain of the amplifier needs adjustment the uplink and the downlink may be
adjusted by means of the step attenuators on the top of the unit. Attenuation from 0
dB to 28 dB in steps of 4 dB may be inserted by proper selection of the 4, 8 and 16
dB attenuators. If satisfactory cell (or two-way) phone performance is not obtained
when the phone is in close proximity to the interior antenna it may be necessary to
decrease the gain of one or both of the links.

TROUBLESHOOTING
All external cables should be carefully checked for “shorts” and “opens”.
The rooftop antenna should be placed so that line of sight obstructions are
minimized.
If cables and alignment are O.K. it may be necessary to use a spectrum analyzer to
examine the signal environment in which the IBA is operating. The existence of
strong analog signals within the frequency bands can cause problems particularly on
the downlink. In some cases additional filtering might be required to reject these
unwanted signals. Automatic Gain Control (AGC) may be switched on by moving the
leftmost dip switch to the on (up) position.
