Is it easy to operate the jammer?
Mobile phone jammers are the best products for blocking signals. It seems easy to install a cell phone jammer. The following article describes how to set up a signal blocker.
A handy jammer is an electronic device that blocks the transmission of signals between a mobile phone and a base station. When using the same frequency as a mobile phone, mobile jammers create strong interference with the communication between the sender and the receiver. Efficiently blocks the transmission of signals from UMTS, 3G, CDMA, GSM and PHS.
Mobile phones operate in different frequency bands in different countries. The 1900 MHz band is the main band in German, especially in urban areas. 850 MHz is used as a local backup. In the United States, the 850MHz and 1900MHz bands are used depending on the region. Europeans use the GSM 900 and 1800 bands as standard. The Middle East, Africa, Asia and Oceania also use these frequencies. In Russia and several other countries, local carriers have a 450MHz frequency license to provide CDMA coverage.
Using different frequencies makes it difficult to install jammers on all frequencies. Previously, you had to manually adjust the signal range to interfere.
However, all jammers currently on the market have corresponding antennas. Simply purchase the corresponding junk model and install the corresponding junk antenna to easily interfere.
