Product Description. The H7 Series Compact Signal Booster are IF SAW based Adjustable Bandwidth signal boosters that operates in the downlink frequency of 763-775MHz and in the uplink frequency of 793-805MHz for United States. For Canada it operates in the downlink frequency of 768-776MHz and in the uplink frequency of 798-806MHz. This Signal boosters extends the radio coverage into areas inside the Base Station range where propagation losses prevent reliable communication. The system receives the UL signal though a Donor antenna to be amplified, filtered and re-radiated through the Service antennas. The DL signal is received by the Service antennas to be amplified, filtered and reradiated through the Donor antenna back to the Base Station. This way, the system works as a Bidirectional Amplifier. This signal booster is capable of handling one Adjustable Bandwidth band from 700KHz to 12Mhz in uplink and downlink. The start and stop frequency can be tuned via a software interface. The intermediate filtering of this equipment is performed using IF SAW filtering technology and, among many, it has the following features: - High Selectivity. - Adjustable BW filter. - Uplink Squelch with configurable threshold and configurable time hysteresis. This Digital Signal Booster has a compact heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed to be wall or pole mounted. UM-0825 Dimensions UM-0825 10 3. Signal Booster Block Diagram This Signal Booster is basically a bi-directional amplifier, the downlink signals are received by the Signal Booster from cell site by the donor antenna, filtered by its internal duplexers and IF filters units, amplified by low noise amplifier(LNA) and downlink PA unit, and then sent via the server antenna to the area to improve mobile signals for mobile phones. The uplink signal of mobile devices from the coverage area is input via the server antenna, then filtered by duplexers and IF filters units, amplified by the uplink low noise amplifier (LNA) and the uplink PA unit and finally sent via the donor antenna to the cell site tower. A detector in the PA stage measures continuously the output level. The signals from this detector is used by the automatic gain control(AGC), to supervise and, if necessary, reduce the chain gain, in order to keep the output power level, under the maximum. All the parameters are supervised by a microcontroller. 4. Installation Mounting the Signal Booster The Fiplex Compact Signal Booster is designed for outdoor usage with a weather proof outdoor cabinet that can be mounted without any kind of shelter from rain, snow or hail. However, to improve reliability, it is recommended to mount the Signal Booster on a site with some kind of shelter from direct exposure to sun, rain, snow and hailing. We extremely recommend not operating the Signal Booster under very bad weather conditions, such as: - Intense rainfall, snowfall or hail - Storm or high wind - Extremely low or high temperature - High humidity of the air UM-0825 11 Mounting 1. Mount the bracket The Signal Booster can be mounted on a wall or pole. These mounting cases are shown below in Figure 1 and Figure 2. The bracket is provided with the Signal Booster. Figure 1 Figure 1 shows a bracket attachment to a wall using three fixing screws. Figure 2 Figure 2 shows a bracket attachment to a pipe using two inox hose clamps (provided with bracket). UM-0825 12 1. After attaching the bracket hang the Signal Booster. Figure 3 2. Screw the cabinet to the bracket To attach the Signal Booster’s cabinet to the bracket use the provided four M6 x 2” allen screws and follow the indicated steps: A - Release Signal Booster cover. Use allen key N°6 UM-0825 13 B - Open Signal Booster cover. C - Place and screw the four M6 x 2” allen screws. D - Close the cover. UM-0825 14 E - Secure Signal Booster If additional security is required, you can lock the cabinet with a padlock. For this, secure the locking pin and turn the lock as shown in the figure. UM-0825 15 Commissioning Figure 4 Figure 5 shows RF ports and AC and DC cable glands location. 1. Connect service antenna (“TO MOBILE” port) and donor antenna (“TO BASE” port) coaxial cables. N type female connectors are used in the Signal Booster. 2. Once RF ports of the Signal Booster are properly loaded connect mains to the AC source. Electrical installation must provide differential and termo-magnetic breaker elements according to electric safety international regulations. 3 Make sure that not used cable glands are properly sealed. For this, use the seal plug and selfamalgamating tape. DB TMB UM-0825 16 3. Auxiliary DC connection can be provided to the Signal Booster from an external DC source. There is a dedicated cable gland for this purpose (EXT DC INPUT in figure 4), and a dedicated DC connector labelled P60002 located at the main board. A 5.5mm x 2.1mm center positive plug must be used. Please check appropriate DC voltage at Signal Booster specification sheet. 4. If the Signal Booster has the NFPA Option, there is a dedicated cable gland for this purpose (“AUX IN/OUT” in figure 4). A multi-conductor cable can be used to connect the NFPA dry contacts to the Fire Department Control Box. NC NO VSWR NC NO Repeater Fail Status of contacts (Alarms Off) Pin 1 – 2 = VSWR (normally closed contact) Pin 2 – 3 = VSWR (normally open contact) Pin 4 – 5 = Repeater Fail (normally closed contact) Pin 5 – 6 = Repeater Fail (normally open contact) Figure 5; NFPA Dry Contact connection configuration Figure 6; NFPA Dry Contact connection location inside the cabinet 5. Once the Signal Booster has been connected to power source (either AC mains or external DC), it takes about 20 seconds to run a booting routine. After that time Signal Booster is ready to be connected via USB cable to a computer running pFOMS in order to be properly configured. See Part 2 Software of this manual to install pFOMS. UM-0825 17 Starting operation 1. Setup desired filter configuration using pFOMS (only for programmable band selective and programmable channel selective models). For fixed bandwidth Signal Boosters this feature will not allow user to make changes, so, skip this step for fixed bandwidth models. 2. Setup desired operating gain using pFOMS. UL and DL chain are independent, so both values must be set. For nominal gain of the Signal Booster these values must be set to zero. Figure 7 Figure 7 shows how to set up manual attenuation values. UM-0825 18 Auto-oscillation Condition If the isolation between donor and service antennas system is lower than required, the amplified signal will go back from service antenna to donor antenna. It will lead to self-oscillation, reducing the coverage area and amplified signal quality. The isolation between donor and service antennas systems must be, the nominal Signal Booster gain plus 15dB, in order to assure the properly operation of the Signal Booster. Status Indicators There is an indicator panel located at the front panel of the Signal Booster. This led panel works as a status monitor, in order to advice different operational conditions of the Signal Booster. There are four leds, first one the power ON indication led, labelled “PWR”. A Second led, labelled “STS” resumes warnings regarding critical operational conditions of the Signal Booster. Third and fourth led resumes operational conditions for uplink “UL” and downlink “DL” chains. Signalling will be explained in table 1. Operative Condition UM-0825 Indicator Panel Start UP 19 2 Stationary state AGC DL AGC UL Overload DL Overload UL Table 1 1. Start UP Every time the Signal Booster is plugged to AC mains (or auxiliary DC power), will start a self diagnosis and booting sequence that lasts around 20 seconds, during this time Signal Booster is not available for traffic, and the reason is because an automatic antenna isolation control procedure runs in order to detect poor isolation conditions. During this time all leds in the front panel will blink. In case of bad isolation condition led “UL” or “DL” (depends on the path where auto-oscillation condition was detected) will stay ON during five seconds. 2. Stationary state Once the booting sequence is finished and under no AGC or Overload conditions only the PWR led must keep ON. 3. AGC DL Blinking condition indicates that AGC circuitry is active for downlink path. For further information please read Automatic Gain Control (AGC) latter in this chapter. 4. AGC UL Blinking condition indicates that AGC circuitry is active for uplink path. For further information please read Automatic Gain Control (AGC) latter in this chapter. 5. Overload DL Led permanently ON indicates that Overload protection circuitry for downlink path is active. For further information please read Overload Protection latter in this chapter. 6. Overload UL Led permanently ON indicates that Overload protection circuitry for uplink path is active. For further information please read Overload Protection latter in this chapter. Automatic Gain Control (AGC) Automatic Gain Control circuitry is intended to keep Signal Booster’s output power at a fixed level when input signals exceed maximum values, avoiding quality signal degradation by intermodulation generation. When AGC is active AGC leds from UL or DL (or both) will blink, this means that signal level from donor site (or from service area) plus Signal Booster gain produces an output power that is above the maximum composite output power of the Signal Booster. This should not be considered an undesired working condition, UM-0825 20 far from that; this is the best operating condition because you are getting the maximum composite output power available from the Signal Booster. Anyway is a good practice to increase attenuation (reducing gain), until AGC led turns off, this operation releases AGC circuitry dynamic range. Also is a good practice to check signals from donor site to ensure that undesired signals are not being amplified by the Signal Booster, or even desired signal levels are not excessively high taking Signal Booster to an overload condition. Overload Protection When AGC circuit reaches its limit, the power amplifier stage is shut down to prevent harmful distortion and potential damage to the Signal Booster. After approximately ten seconds the system checks if overload condition is still present, if this happens amplifiers will remain off. This cyclic check will continue until condition that makes AGC circuitry reach its limits disappears. Conditions that can cause AGC to reach its limits include the presence of one or more very strong channels, a strong in-band noise source, or amplifier oscillation due to poor antenna isolation. When overload protection lower row led from UL or DL (or both) will be ON permanently. Laboratory Measurements For specific parameters verification and laboratory tests, please contact factory. Detailed procedures, recommended tests set up, and a knowledge engineering team will bring adequate support to perform this measurements in a comfortable and safely way. UM-0825 21 Part 2 SOFTWARE 5.
