Yes, 5G signal can be blocked in a variety of ways. One common way is by physical obstructions like walls and buildings. These physical obstructions can disrupt the direct line between the 5G signal transmitter and the receiver.
Other methods of blocking 5G signal include using signal jammers, which interfere with the frequency of the signal or interfere with the signal’s modulation. Additionally, some countries have enforced laws that restrict the transmission of 5G signals, or even restrict certain types of devices from accessing the signal, creating a de facto blockage.
Ultimately, 5G signal can be blocked in a variety of ways depending on location and type of signal.
