Phone:+86-13603042894Users must follow the below principles:
1. Repeater should follow system requirement of communication
equipment, assure good groundings and lightning protection.
2. The power supply voltage of repeater should meet the standards of
security requirement; any repeater-operator can operate only after
cutting power in advance. only the professional can operate
electrified.
3. Do not dismantle machine, maintain or displace accessories by
yourself, because in this way, the equipment may be damaged or
even get an electric shock.
4. Do not open the repeater; touch the module of repeater, even not to
open the cover of module to touch the electronic component, the components will be damaged due to electrostatic
5. Please keep away from heating-equipment, because the repeater will
dissipate heat when working. And do not cover repeater with
anything that influences heat-dissipation.In mobile communication, it is inevitable that macro-cell coverage cannot cover weak or dead zones; to use repeater is a good choice in these areas. Dual wide band repeaters mainly applied in covering small blind and weak zones. Such as VIP rooms, offices, houses, restaurants, apartments, parking lots, etc.
Quad band, five band repeaters enhance consumer satisfaction greatly with its integrated design, compact size, easy engineering and rapid installation and debugging.3.1 Product Descriptions
(1) In Terminal: N FePaper Machinery male
(2) LED: To monitor the status of poweron/off and normal operation
(3) Power Supply Terminal: External
(4) Power supply (Operating voltage: 9V/ 5A)Features Compact design and light weight, cost effectiveness LED indication for operation status. Wide band function to work on any network combined by GSM,DCS,WCDMA ,LTE support. Low power consumption, Low interference. Applicable to In-Building with medium or small size with Maximum coverage up to500-3000 Square metersALC to limit output power at specified power level and ensure stable coverage effect.AGC function by 1dB/step from 1-31dB Gain range.1 Installation requirementsQuad band, five band repeaters are mainly applied to indoor coverage solution . After connection of equipment and antenna, the distance of them should be keep as far away as possible, it's better that there is a wall as the obstruct between them( far than 15 meters).Position selectionInstall in the place that is not easy to be reached by irrelevant people.Install at the place that is convenient for power supply and cablingAvoid heat source and moist environmentPower supply requirementAC power supply ofElectromagnetic Equipment AC 95~264VInstallation tools and accessorierInstallation Steps:
1: Use percussion drill to make four Φ7 holes on the wall according to above hole diagram, fasten the Expanding plug onto the wall.
2: Screw up repeater to the wall.
3 ConnectionConnection of RF cableBTS port connect with the outdoor antenna , put antenna on the place where there is strong signal, then connect to MS port of equipment and assure good connection.Grounding connection Use earth wire to link the repeater grounding port with building grounding system. Power resistance must be less than 10 OhmPower supply connectionPlease use three-pin plug to assure good grounding
Please check whether the connection of RF cable is correct (donor Packing Machinery antenna connected to input port, service antenna connected to output port), and whether every port is stable. After affirmation, please go along the followings:5.1 Power supply connectionAfter power supply connection, check ALARM and POWER indicators first.Downlink gain settingAs for the downlink working performance, "At the edge of green" is a good working point. At this time, downlink output power and coverage effect are stable.
But from another point of view, we hope the equipment is as far as possible away from overloading status of "red" (thus the equipment would hold higher interference depression ability). So we try our best to set the equipment near "edge point" when engineering.
Setting of "edge point": (Switch on the power supply after connection with donor antenna and coverage antenna, and observe ALARM indicator.)
Uplink gain settingUplink gain is set based on downlink gain..
Advantages:
1.
The installation of a repeater is easy and simple. With its plug and play design, installation simplicity, and operational user friendliness, these features appeal greatly to many operators for the purpose of indoor coverage or for temporary coverage during network optimization.
2. Smart Function, Intelligent mode setting
smart function called which can be activated via the front panel.
users can adjust gain and choose working band by LED panel, It is a simple, safe and effective way.5.3 Auto Level ControlThe 30dB ALC is used to maintain steady output power even when the donor source signal fluctuates. Also when the ALC is aLifesaving ctivated>1-5dB, the LED indicator would be lighted in RED, which means the Isolation may not be enough.6.1 OpConstruction Equipment & Tools eration and maintenancePower supplyPlease make sure the voltage and frequency comply with the repeater requirement.Component replacementPlease do not maintain or replace components by yourself, otherwise may get an electric shock. only the authorized professional can maintain and replace the components.Waterproof and moist proofPlease do not turn on or off the booster in moist environment when its door is opened.6.2 Emergency dealingSwitch off is recommended during following situations:The power supply is not normalLiquid flows into the equipment; Working conditions is not normal, (overheating, abnormal smelling, abnormal sundries)Closet damageperformance debasementnear to fireflooding6.3 Maintaining directionPlease check the repeater step by step according to below process, to find out the problem with the repeater.
