When do whole shield in the common office building, dormitory, if it’s structure is "corridor in the middle", wall-mounted installation in the corridor (aisle) inside the building, we need to consider the overall appearance of various shielding point. Generally, we unified install multiple cell phone signal jammers in the same side of the corridor.4G Cell Phone Jammer
But if it’s inconvenient to install at the installation position or it’s difficult to connect to the power, the selected point is used by other devices, or direction of each door in every rooms is different and irregular, in order to reach the best shielding effect in the building, it’s recommended that as per actual situation of each floor, use dislocation distribution in two sides installation method, that is multiple shielding points been cross distributed at each side of the corridor. 4G cell phone jammer As following pictures:
Directional antennas on the top floor should be installed at downward direction
On four side length of roof of the building, install a cell phone signal jammer at every 10-20m, used in conjunction with directional antennas, antennas downward to the ground. This is a new 4g cell phone jammer installation method and another alternative method when it’s inconvenient to do “Exterior wall make up point installation method”.
At first, the installation method can solve problems like inconvenient construction at some situation and maintenance in the future of “exterior wall make up point installation method”. Because cell phone signal jammer been unified installed on the roof, it’s convenient for unify power supply. While the host and the antenna itself is below lightning rod that comes with building, erection of lightning rod procedure been reduced.
At the same time, if position of “exterior wall make up point installation method” is on the third and fourth exterior wall, it will bring construction and maintenance in the future troubles because of the height. It can just be avoided by the:” directional antennas on the top floor are installed at downward direction” method.
Relatively speaking, comparing with “exterior wall make up point installation method”, change to directional cost been added to this method. But because choose directional antennas, all the shielding range is limited to inner of the building and 10-20m around the building. The unnecessary influence to outside world is smaller.
When apply this method in practice, first should according to the predict point to install cell phone signal jammer and directional antennas, after all cell phone signal jammer turned on, check in the building to see if there is signal blind area. If there is, we should adjust distance of each cell phone signal jammer or add cell phone signal jammer quantity. In individual cases, we may make up 4g cell phone signal jammer in inner blind area of building properly.
To choose cell phone signal jammer model is very broadly. Common model include: SMa-818B、SMa-818HB、SMa-818C、SMa-818HC、SMa-818YB、SMa-818W and other models.
