LCD Display ! GSM 900 GSM2100 Cell Phone Signal Booster UMTS 2100MHZ Amplifier GSM and 3G Repeater +Power Adapter
1.GSM900MHZ+2100MHZ dual band repeater ,amplify double signal
2.Dual band,2G+3G SIGNAL EXTEND
3.500-2000sqare meter coverage without barrier
4.65db high gain 20dbm output power
5.Easy to install.
Cell phone signal amplifier (also referred to as signal booster or direct signal amplifying station) is designed to solve cell phone signal blind. In some location such as remote area from base station, high-rise, basement, location behind by building, underground civil air defense projects, subway stations, elevator and many other places, cell phone can not be used due to receiving signals fail. This cell phone signal amplifier is aimed to solve the problems.
1.High linear design,AGC/MGC function.Little interference to BTS
2.Provide quick coverage solution for signal weak and blind area,no more drop calls.
3.Compact size,low consumption,great cover.
4.Cover about 2000sqm without barrier
5.Suitable for all countries,amplify gsm+wcdma signal where signal is weak or blind.

1.Support Maximum coverage area is 2000 square meters.( Depend on the area condition)
2.One indoor antenna only use for about 100 square meters. (in open space).
If want to make all use of 2000 square meters which the host supports,
need to add more indoor antennas (about 20) and power divider / splitter.
1x GSM +WCDMA repeater (2G+3G SIGNAL Amplifier)
1x power charger (We send EU adapter, if you need additional adapters, please leave a message, thank you!)
1x Instruction manual
1 around the use of mobile phones on the top of the building or to find the direction and position of the strongest signals, as the location of the installation outside antenna
2 after selecting the appropriate position will indoor ah you fixed on the wall or support
3 in related indoor location choosing appropriate location (this site for nearly power supply and outdoor antenna side rain sunscreen and well ventilated for best location) install indoor machine and fixed on the wall or support
4 will be introduced to the outside antenna is suing (OUTDOOR) interface links at this point and OUTDOOR antenna and indoor amplifier
May determine the installation position of indoor antenna fixed antenna
6 INDOOR antenna and received the INDOOR antenna amplifier connection end interface on the other end of receiving repeater machine INDOOR (INDOOR) port
Mobile signal amplifier installation considerations:
1, outdoor antenna installation location must be able to clear on the phone, the installation must be level yagi.
2, eight wood and the distance from the antenna suction a top as far as possible, more than 8 meters, not in the same line of sight range, lest cause self-excited, typical generally use a wall for isolation, the effect is good.
3, 75-5 coaxial line is usually F head through to the host, should be an absolute guarantee F head fastening, recommend the use of 75-7 coaxial feeder effect is obvious.
4, F head must be for 75-5 inch line 75-5 coaxial line should also form a complete set, can appear otherwise can\'t install.
1, mobile phone signal amplifier can produce radiation, affect the body health?
A: definitely not.Power is not big, because the downlink power output is only about 500 mw, the relative maximum transmitted power of GSM mobile phone, only 1/20, very small.
2, have electricity, two lights are not bright??
A: very likely ac power supply is unreliable, suggest change the socket.
3, signal full, can\'t call, but can come in, what\'s the problem?
A: the reason for the mobile launch of signal transmission to the base station can not be a good cause, for many reasons, generally can be adjusted through the yagi direction, such as rotate 360 degrees, choose a good point of view, fixed again.If still can\'t solve, you can consider whether or not the connection and joint is too long, or loose, and tighten in place.General section of line no more than 20 meters suitable outdoor, indoor section of the line is not more than 10 meters.
Scope of application:
1) signal blind area of small area or weak signal area: such as underground or semi-underground place of business, small basement, underground parking, etc
2) small hot signals complaints area: such as conference room, small supermarkets, shopping malls, office rooms and small public areas, etc
3) traffic and social influence of big area: bars, Internet cafes, dance halls, cafes, fitness clubs, leisure entertainment, etc
4) elevator, especially in the elevator shaft inconvenient to lay cables of the elevator
5) family, office, luxurious yacht, car, * * system and road safety?Fei miaotuo magpie?
6) there is no signal within a large workshop
1) high gain of linear power amplifier
2) automatic level control
3) low noise receiving amplifier
4) there is no disturbance to the base station, opening without need of the original system and the base station parameter to adjust
5) stable and reliable electromagnetic compatibility design
6) do not cause the increase of base station background noise, will not lead to a drop in the quality of base station communication
7) in full-duplex communication way
8) cooling effective and reasonable, beautiful structure, volume is appropriate
