Mobile phone and WiFi jammer adopt directional antenna design

There are many online stores that sell signal jammers, such as cell phone signal jammers, GPS phone signal blockers, WiFi signal blockers, UHF signal jammers, and other types of signal blinds. However, now we rarely find powerful signal detection equipment, which has the ability to intercept 4G signal signals, and is suitable for indoor use, and has a large interference distance.

Newspapers are worried about many major issues (street closures, traffic jams), but they also raised more specific concerns: Will the British government selectively block the mobile phone signal Bush on the President ’s route?
