Which wifi jammer is more suitable for home use

For household jammers, you can choose a multi-functional signal wifi jammer, which will interfere with wifi signals and mobile phone signals, including GSM, 3g, and 4g signals. Whether you are talking about the behavior you are monitoring or your child is addicted to the Internet, but not concentrate on learning, it may be a necessary signal shielding to ensure your safety and let your child put down the phone to learn.
