cell phone disruptor abstract

Among those who useย cell phone jammer, some are to prevent cheating in exams, and some are to quiet the meeting place or keep the meeting information confidential. These are all for good wishes and purposes. But there are also for their own personal benefit. For example, the owner of a public phone may use a jammer to interfere with the mobile communication base station near his business location, so that people working near the public phone they operate, and the mobile phone is not working well, so they use it instead. Public telephone calls increase their economic income. In addition, mobile communication operators may also use shielding devices to harm each other's interests, so that they can gain an advantage in certain local competitions in the same industry. In addition, the mobile phone signal jammer is also easy to add software, becoming a veritable eavesdropping.
