The cell phone jammer can use jammer’s omnidirectional antenna

Currently, the cell phone jammer is widely used in industries and locations, including the meeting room, examination room, prison, school, jail/work camp, theater, petrol station, oil depot, library, factory workshop and so on. Here introduces how to select installation positions of the cell phone jammer in the commonly applicable places.

Single Space (Minor and Mid-sized Meeting Room)

For the normal minor and mid-sized meeting room (the area is normally smaller than 300 square meters) whose inside is the transparent environment, it is easier to select the position of the cell phone jammer and the needed positions are less.

100-300 Square Meters

For the meeting room whose area is about 100-300 square meters, 1-2 small-power cell phone jammer installed inside are enough to shield the whole meeting room.

Installation place of the cell phone jammer depends on the site environment. If the top of meeting room is the ceiling floor or unfixed sprung roof, the jammer can be installed in ceiling or sprung roof or in the meeting table inside the meeting room, a certain corner or a wall.

The cell phone jammer can use jammer’s omnidirectional antenna which can changed into directional antenna if reducing interference with outside environment is needed.

The cell phone jammer types are various. SMa-818B、818HB、818W and so on are commonly used and SMa-818C、818HC、818YB whose power are adjustable can also be selected.

Over 300 Square Meters

For the single space whose area is more than 300 square meters, the installation position of the jammer can be selected as per the site size using equally spaced positions. The quantity is normally more than 3.

For the installation position of the cell phone jammer, if it can be installed on the ceiling floor in the middle, complete covering effect can be achieved with the least points, otherwise, installation method on the wall at two sides should be adopted.
