Are mobile phone jammers effective for elderly phones?
Recently, a customer asked such a question. The original mobile phone signal jammer for sale of the unit has a good shielding effect on smart phones, but the shielding effect on elderly phones is not very good. Why is this?
First of all, according to the principle of mobile phone jammers, mobile phone jammers interfere with the communication signal between the base station and the mobile phone, which has nothing to do with the brand and model of the mobile phone. However, due to the differences in mobile phone manufacturers, production processes, and components used by various mobile phone manufacturers, mobile phones of different brands and models also have certain differences. We do not consider other functions, but only discuss the ability of the mobile phone itself to receive signals. Under the same signal strength, the mobile phone itself has a strong ability to receive signals, and the mobile phone can be used normally in places with weak signals.
However, at this time, the signal strength from the base station to this place has not changed, and the shielding range of the mobile phone jammer depends on the distance of the base stations around the use site, that is, the signal strength from the base station to the use site. It has nothing to do with the brand and model of the mobile phone. The reason why the elderly phone cannot be shielded at the use site is that the elderly phone has a stronger ability to receive signals. However, if the signal on site has been interfered by the signal of the mobile phone jammer, then even the elderly mobile phone will still have no signal.
If the mobile phone jammer does not have a good shielding effect on the elderly mobile phone, then the mobile phone jammer must be adjusted, either by increasing the transmission power of each shielding module of the mobile phone jammer, or choosing a high-power mobile phone jammer, or rationally adjusting the shielding module of the cell phone blocker, and further refining the output frequency of the shielding module, that is, to add shielding modules and reasonably split the transmission signal frequency of the shielding module. For example, the output frequency range of the original shielding module is 80MHz. By adding modules, the 80MHz frequency is divided into two shielding module outputs, so that the shielding effect can be relatively improved, and the signal frequency band used by the elderly mobile phone can be targeted.
