Collection: 4G 2300-2400MHz Phone Blocker

Between 4G frequency bands, the working frequency overlaps. This is because the deployment of 4G by national operators is different in the world. However, within a country, a certain section of wireless frequency will be allocated to a single operator for commercial use to avoid wireless interference. The authorized spectrum in the mobile communication system, this authorization means that the use of wireless frequencies in a certain area needs to be officially authorized.

Although 5G has appeared now, 4G 2300-2400MHz is still an important frequency band in North America. 4G jammers can block the 4G 2300-2400MHz frequency band, so that mobile phone communication has no signal and no network.
