Cellular Specialties, Inc. developed the Model 510 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 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.
PRODUCT DESCRIPTION
Bi-Directional Amplifier (BDA) for use in
smr900
for a total of 60 dB nominal
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
Important note: 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. 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.

CONNECTED DIRECTLY TO THE BDA OR THE COAX THAT
A high degree of isolation must be afforded to prevent any re-

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.

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.

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.
