MANUAL610SMR OMNI 4 PRODUCT DESCRIPTION Cellular Specialties, Inc. developed the Model 610smr 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. 2.0

MANUAL610SMR OMNI 7 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. 4.0 ! WARNING! AMPLIFIER DAMAGE WILL OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE IBA OR THE COAX THAT LEADS TO THE IBA.
MANUAL610SMR OMNI 8 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. !
MANUAL610SMR OMNI 9 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. !
MANUAL610SMR OMNI 10 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. 5.0
MANUAL610SMR OMNI 11 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. 6.0
