This antenna-covered car was behind TACO's Beast, and the moment it passed in front of us, all the Japanese people were shocked because our earphones' Bluetooth was forcibly disconnected and our smartphones lost signal for a moment.
What kind of incredible car is this?!
I looked it up and found out it's an Electronic Countermeasures Vehicle called a Watchtower.
I'd never seen such a special vehicle before, so it was quite a shock. :pikachu:
@MENUMA432 In us there are devices nicknamed stingrays that intercept all cell or wireless data in an area and monitor activity.
@MENUMA432 As well as jammers like the one you encountered
@MENUMA432 It is very similar here, only official agents are allowed to use such devices. While I don't know of any laws specifically banning them, consumer jammers are sold online, and I'm sure a charge of interference with communications could be used if someone was causing trouble and got caught.
@Jazzy_Butts
However, here in Japan, the act of intercepting and decrypting other people's communications without permission using an IMSI catcher is prohibited by the Unauthorized Computer Access Act, and you could be subject to criminal penalties... (^.^;)
