PRODUCT DESCRIPTION
Cellular Specialties, Inc. developed the Model 510smr900 Bi-Directional Amplifier (BDA) for use in
enclosed structures where sufficient signal from local cell sites to operate cell phones was unavailable
within the building. It is necessary that sufficient signal be available on the roof of the structure. The
BDA 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 usually a directional type such as a "Yagi" however an omni-directional
antenna may be 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 BDA 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 four amplification stages on the downlink and four on the uplink for a total of 60 dB nominal
gain for each link. Both links have manual gain control settings accessed through DIP switches on the
top of the unit plus an AGC control for both the uplink and downlink. There are LED indicators for
power on, transmitter on, uplink overload and downlink overload.
An automatic amplifier safety shutdown circuit is also present which will disable the transmitters for ten
seconds should the uplink or downlink overloads be reached to prevent excessive intermodulation and
oscillation.

INSTALLATION
CSI recommends that all BDA installations be coordinated through
the local wireless provider.
Note:
The Installer should refer to the Safety Precautions, in the
following section, for proper antenna selection and installation
WARNING!
AMPLIFIER DAMAGE WILL OCCUR IF A HANDSET IS
CONNECTED DIRECTLY TO THE BDA OR THE COAX THAT
LEADS TO THE BDA.
Important note: A high degree of isolation must be afforded to prevent any regenerative 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. The minimum
required isolation of 70 dB can usually be 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 Limits for
General Population/Uncontrolled Exposure.
For OUTDOOR use, a Directional Antenna up to a maximum gain of 3 dBi is
authorized for use with this unit.
The Outside antenna must be positioned to observe minimum separation of 20
cm. (~ 8 inches) 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 inches) 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 Limits for General
Population / Uncontrolled Exposure.

AMPLIFER ADJUSTMENT
In most cases the BDA will need very little adjustment. After connecting the coax and
powering up the BDA, the signal levels within the previously surveyed areas should
be checked for adequate RSSI 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 BDA.
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 cables should be carefully checked for “shorts” and “opens”.
The rooftop antenna, if directional, should be checked for proper alignment along the
calculated compass heading. Typically, the directional antenna should be aimed at
the same site that your handset uses in the area where the outside antenna is
placed.
If cables and alignment are O.K. it may be necessary to use a spectrum analyzer to
examine the signal environment in which the BDA 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. In some instances the directional outside antenna can be
reoriented, horizontally to place the interfering source in an antenna pattern “null”.
There also may be some cases where the interference from outside signals is so
great that they can not be filtered or otherwise reduced or eliminated without
expensive and possibly prohibitive measures. In these cases it may not be practical
to use the BDA for providing coverage at these sites.
