This is the latest portable 2G 3G portable 2G device. In addition to interfering with 4G LTE and 4G Wimax signals, you should also avoid using CDMA, GSM, DCS, and 3G signal functions. It is currently the most complete and powerful interference device. In addition to the group you want to choose, it’s up to you. If you don’t want to block one or two bands, you can turn it off and leave the other bands open.

GPS shielding and jamming expert Humphreys warned that this could have a significant impact on U.S. drones, which could cause them to malfunction or even crash. He said that if the drone reported incorrectly or was missing, it would “at least cause confusion for unmanned ground operators.” According to Dr. Humphries, four years ago, after the Crimea invasion, the United States Analysts first discovered that the Russian army blocked drones in eastern Ukraine. These GPS radar jammers “have a significant impact on the drones deployed by the United Nations for surveillance missions in the area.” The crew stopped for a few days, unable to collect information by plane.
