Can Blocking Cell Phone Numbers Telus Block 4G Signal?

Perfectjammer 2022-03-02

There are several types of mobile communication network signals we use every day. In addition to the 4G network signals that have been popularized at present, there are also 3G network signals that were popular in the past few years, and 2G network signals used by some elderly phones. Although the 5G network signal has become a topic of discussion for many people now, it will take some time before the 5G network is popularized. Today, let’s talk about the topic of installing Blocking Cell Phone Numbers Telus Can 4G network signals be effectively shielded, so that you can have a more comprehensive understanding of the functions of Cell Phone Jammer . First of all, it is clear that mobile phone signal jammers can block 4G network signals. When the mobile phone works, it is within a certain frequency range. The mobile phone and the base station are connected by radio waves to complete the transmission of data and sound with a certain baud rate and modulation method.

For this communication principle, Blocking Cell Phone Numbers Telus scan from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc. The key to shielding 4G network signals is to look at the frequencies supported by the selected mobile phone signal jammer. The current 4G frequency band range is very wide, from 800M-2.4G. If you want to shield the 4G signal, it depends on the mobile phone signal jammer you use. How much bandwidth can be supported. Because part of the 4G frequency band almost coincides with the 2.4 of WIFI. Once you block the 4G signal, the WIFI and Bluetooth in the shielded area may not be used normally. Therefore, whether the 4G signal can be shielded mainly depends on the function of the mobile phone signal jammer product and whether a 4G signal shielding module is installed.
