The shielding range of a cell phone signal jammer depends on the following factors:
Are you worried about incomplete shielding? Are you worried about a complex signal environment or a limited budget? Are you worried about damage or a short device lifespan? Do you only want to block one signal but are concerned about affecting other frequency bands? Are you worried about being discovered by others? Are you worried about the jammer's appearance and its impact on the indoor environment?
Dazhan Electronics' custom solutions can help you solve all these problems!
Cell phone signal jammers are categorized into the following categories based on their shielding range and the port data used:
First: How many meters a jammer for sale can block depends not only on its own transmit power but also on the distance from the base station in the environment (base stations are not limited to large, ground-based transmission towers; they also include signal amplification antennas on rooftops and distributed signal amplifiers within some buildings). Another important factor is the obstacle: Metal will directly block the signal; solid reinforced concrete walls will attenuate the signal by at least 10 times after penetrating.
Second: The strength of the magnetic field signal. When the magnetic field is weak, one cell phone signal jammer can be installed for every 2.5 classrooms. If there are 10 classrooms in a row, three in the hallway are sufficient. When the magnetic field is strong, if there are base stations within 500 meters, 300 meters, 200 meters, 100 meters, or even on rooftops, the situation depends on the situation. The stronger the magnetic field, the more locations you need to install cell phone signal jammers.
The third type: A small-scale, 0-10-meter area, up to 120 square meters. Low-power cell phone signal jammers. The shielding effect varies depending on the distance from the base station, and the shielding range is primarily determined by the strength of the magnetic field. Handheld 4-way and 6-terminal cell phone signal jammers are recommended. Low-power jammers weaken the signal when penetrating walls, so if wall penetration is required, low-power jammers are not recommended.
The fourth type: If there are no base stations within 1 kilometer. Within 120 square meters, one is sufficient. For 120-250 square meters, two are recommended. For large conference rooms under 150 square meters, it's recommended to install one jammer, for conference rooms under 250 square meters, two, and for conference rooms over 600 square meters, four. Installing three or more jammers in a single area will create a honeycomb-like shielding effect.
Therefore, when installing cell phone signal jammers, it's important to first understand your surroundings and the area you'll be using before deciding on the type of jammer you want to purchase.
