Protectingwirelesscommunicationsincombat
Inthiseraofhighlydevelopedinformationtechnology,mobile phonecommunicationsandnetworkconnectionshavebecome anindispensablepartofourdailylives.However,insomecases, wemaywanttotemporarilyblockthesesignalsandenjoya spacewithoutinterference.
Imaginethatwhenyouareinclass,yourmobilephonesuddenly startstoring.Howembarrassing!Theemergenceofsignal jammercanbeusedinsuchoccasions.
Mobilephonesignaljammersaremainlyusedtoblockthe receptionandtransmissionofmobilephonesignals.Inaquiet conferenceroom,everyoneislisteningattentively,andsuddenly someone'smobilephonerings,andtheatmosphereisinstantly broken.Afterusingthesignaljammer,theconferenceroomis like"magic",andallmobilephonesignalsare"invisible".
