Questions of life: Why is there no signal jammer on the plane?

The reason why mobile phones cannot be used on airplanes is to prevent mobile phone signals from interfering with airplane communications. Installing a "jammer" means installing a huge source of interference by yourself. Therefore, there will be no such device on the plane!
