It looks like a walkie talkie, but this little box is more powerful than you think. When it is turned on, it can block any mobile service in the area.
A man in Philadelphia is tired of speaking on the SEPTA 44 bus phone, and according to Philadelphia NBC 10, when he doesn’t want to hear the conversation, Eric will shoot the very disturbing man.
Eric told National Broadcasting Corporation (NBC) 10: “A lot of people are noisy. When I mess up the antenna and turn on the switch, when they are confused, they have little privacy or anything.
It seems like someone is talking loudly with a cheap laptop jammer, others around you are not polite, this is a common problem on buses, and this problem requires their voice to give them one of the dirtiest means. Therefore, we recommend that you use a portable 3G 4G 3G mobile phone interceptor and all gps jammer on the bus. Only in this way can we return a quiet environment to society.
When you are not talking loudly with other passengers on the phone, you can use the phone jammer to eliminate this situation in time. When a fellow passenger speaks loudly, almost 2G 3G 4G mobile phone is the mobile phone signal and all GPS signals: Band 1: 4G: 1710-17775 MHz, Band 2: GSM: 851-960 MHz, Band 3: DCS and PCS: 1805-1990 MHz , Band 4: 4G: 2500-2690 MHz, Band 5: CDMA: 725-770 MHz / 790-820 MHz, Band 6: GPS L1: 1500-1600 MHz, Band 7: 3G: 2110-2170 MHz.
The maximum distance coverage is 20 meters, and the radio signals from the bus are on standby-this is an easy way to avoid people who are noisy, without privacy or people. When bored, you can tighten the antenna and turn the switch-of course, you can choose the antenna for different working channels. GPS tracking can also be blocked. If you are a regular passenger on a bus and sitting in a telephone chat, a telephone signal jammer can help you solve the problem.
