Phone Jammer provides the ultimate solution in any area where cellular communications frequently cause nuisance either by loud incoming call rings or loud telephone conversations. Phone Jammer is suitable in executive offices, board meetings, conferences, seminars, libraries, cinemas, religious places, public transport, concert halls, restaurants and educational institutions etc.
Functions:
- Phone Jammer transmits low power radio signals to cut-off communications between cell phone and cellular base-stations. It does not interfere with any communications other than cellular within the defined regulated zone.
- Upon activating Phone Jammer, all idle phones will indicate "NO SERVICE". Incoming calls are blocked as if the cellular hand phone is OFF.
- When Phone Jammer, is turned off, all cell hand phones will automatically re-establish communications and provide full service.
Features:
- Taking use of technology of interferencing superhigh frequency.
- Intelligence controlling technology taking charge of the power outputting within the scope of 10 meters.
- High effective channel power with rater bif semidiameter of interception.
- Effectively making subsections, just interferencing downlink and causing no interception of base station.
- Imported elements: Slow startup design of circuit can avoid the apearance of sparking when turn on or turn off the machine. Futhermore, these elements can maintain the stable operation condition with high intergration.
Conectivity capacity:
- Four SMA interfaces, which are using to connect antenna (GSM/DCS/CDMA/PHS).
- One power supply interface (DC5V IN)
Operation Instructions for Indoor Signal Amplifier of Cellular Telephone
Part One: Brief introduction
The serial cellular telephone signal amplifiers are a kind of extremely kind of effective equipments, which can be sued to remedy cellular telephone network covered with insufficiently, and expand the base station coverage, pack & cover “blind area”.The amplifier is suitable for the remote mountain area, the housing district, the underground market, the parking area, the supermarket, hotels, the escalator, the family, the office building, industrial and mining enterprises, etc, to make the room signal amplify. It will have obvious improvement function to converse normally at the weak signal “blind spot” of the cellular telephone so as to make your cellular telephone converse smoothly.
Part Two: Characteristics
- Adopt Japanese latest original enlarging devices with low noises to improve signal receive sensitivity and SNR effectively, make the tone quality clearer.
- The system effect is improved greatly, which have instant effects to the faint signal area, in which the mobile can not be dialed, or received, or the communication is not clear, or cutting off during the dialogues etc …
- Adopt CLASS A amplifier to be designed, little pronunciation is distorted, and automatic power is controlled, so that it will not cause influence on the base stations and communication environment around.
- Adopt the ripest duplexing from, with lowest noises, single antenna, it is very good to pierce through strength, export steadily, both China Mobile Communication and China United Communication’s signals are compatible, it is easy to be installed and debugged.
- It enjoys the wide voltage range of power supply, suitable for different grid use of all area. The unique signal indication function can monitor signal power at any time, and the installing can be finished with ideal result without the help of professional personnel or special – purpose instrument.
Part Three: Installation and Debug Explanation
- The installation & debug of the outdoor antenna
Before the debug, connect the cellular telephone amplifier first, confirm position where the outdoor antenna set, and try best to choose the rooftop or other higher places to put the antenna. And make sure there is no high mountains to stop the signals in the front when the outdoor antenna aims at the direction which base station launches, using 2-3m long coaxial cable line to link the outdoor antenna with OUTDOOR in the amplifier, when the indicator lamp of the signal is the brightest without glimmering, the cell-phone has the strongest signals, and direction is the most accurate, the coverage is the largest, and at last fix the outdoor antenna.
- Please refer to the following sketch map (Fig. two) to install:
Suggest choosing 50 ohm, 7D coaxial cable, and the length of circuit is not more than 50 meters. Of course, you can also use 75 ohm C7, C9 TV coaxial cable instead.
- The installation & debug of the indoor antenna
To choose 1-10 meters of coaxial cables to connect with amplifier INDOOR when debugging the indoor antenna, and it should be placed on the centre of the necessary service range, try to reduce the stopping of the wall, and through adjusting different position of the antenna to make the cellular telephones have good conversion in the necessary service range. In case that indoor environment is too complicated to balance, then try to output several indoor antennas to different service areas via work-dividing device.
Part Four: Precautions
- The antenna shaking frequency direction must be with getting vertical ground, otherwise influence the performance of the cellular telephone amplifier.
- No permitted to connect the indoor antenna while debugging the outdoor antenna, otherwise will cause the cellular telephone amplifier to defy by itself, so that to influence the result of debugging.
- The outdoor antenna interface, and the indoor antenna interface of the cellphone amplifier can’t be instead, otherwise the cellular telephone amplifier has no result.
- The distances between the indoor antenna and the outdoor antenna should be more than 8 meters (separated with the wall), otherwise apt to cause the cellular telephone amplifier to defy by itself.
