The effective shielding distance (30-40 meters) of the mobile military bag phone signal jammer generally refers to the indoor distance. In an open outdoor area, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether it is used indoors or outdoors, the effective shielding distance of mobile cell phone jammer has a certain relationship with the environmental conditions at the time, such as the distance from the base station, and the location where it is placed. Therefore, when using mobile phone signal jammers, this factor should be fully considered to avoid shielding blind angles and thus affecting the shielding effect.
The shielding range of the mobile phone jammer is based on the power of the jammer. If it is tested in the field according to the strength of the local environmental signal, the shielding range is different. For example, the weak shielding range of indoor signals is large, and the accessories for outdoor use are GSM base stations. Then the GSM signal is close to the outdoor shielding range!
