What issues should be paid attention to when testing full-band signal jammers?
Nowadays, more and more companies are using full-band signal jammers for phone, and the feedback after using them is very good. At present, companies that install and use such equipment include: schools, prisons, police stations, military, examination rooms, dormitories and other areas where signals need to be shielded. After the full-band signal jammer is turned on, it will block the mobile network in the area in all directions. The shielding frequency band types are: 2G, 3G, 4G, 5G, wifi and 2.4G networks.
Full-band signal jammers can be used in different occasions, and the complete shielding area will vary accordingly. This is closely related to the corresponding local signal size and strength. In addition, the interception range at the same site may not be the same due to different types of mobile phones.
When selecting the test area for the full-band signal jammer, it is also necessary to understand whether there are communication base stations nearby and the actual distance between the test sites. It is generally stipulated that the distance between the communication base station and the test site is 300 meters away, and the middle is shielded, and the test effect is relatively ideal.
After selecting the test address, gradually build a full-band signal jammer. For irregular assembly, the full-band signal jammer needs to be erected on the table; for fixed wall-mounted assembly, the full-band signal jammer installation height is required to be within the range of 1.5-1.8 meters. The full-band signal jammer has been adjusted and aged before leaving the factory, and it can be used directly after plugging in, without any adjustment.
After restarting the full-band signal jammer, prepare various models of mobile phones, follow the front direction of the antenna, and gradually move away from the full-band signal jammer in parallel. Set the 5-10-15-20-25 meter position respectively, make sure there is no obstruction in the middle, keep the mobile phone at the same height as the shoulder, stay at multiple points for 2 minutes, check whether the mobile phone has a signal, and try to make a call and surf the Internet. If it cannot be connected, move to the next point to perform the same operation. Until the point where the phone can be connected, the point cannot be blocked.
