What is the relationship between cell phone and portable jammer is? Let’s learn from this. By signal interference on the same frequency and the sufficiently high power transmission over a cell phone signal, the two signals neutralize and cancel each other out. The phone will increase the power, they will experience low interference. Meanwhile, the jamming signal should identify and match the increase in the power of the mobile phone. Telephone is a full-duplex device, two separate frequencies for speaking and listening simultaneously. Blocking signal interference can only use one of the cell phone frequencies. Therefore, only one frequency is received over the phone, and deceived into thinking that there is no service.
For a cheap cell phone jammer, the interference of the signal played on the correct frequency. The phone has different signal processing, but all telephone networks using radio signals may be interrupted. The player can broadcast and AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN system and Nestel at any frequency. Old-fashioned analog cell phones and digital devices today are also vulnerable.
Hills and building walls can block the interference signal, so the actual response to the interference depends on the power and the local environment. Low power signal interference can block the calling range of about 9 meters. The more the number of power units create a free-cell law enforcement area can use up to 1.6 kilometers.
