What is blocker Jamming Signal in Networking

In addition to the enhancement of signal strength by transmit power and antenna gain, path loss and obstacle attenuation will weaken signal strength, which belong to the category of signal attenuation. In addition, interference and noise in the environment will also weaken the signal strength, which belongs to the category of signal interference. When designing the network coverage, unnecessary signal attenuation and jamming signal should be minimized, the signal strength should be improved, and the effective transmission distance of the signal should be increased.

The signal strength of the network signal will gradually attenuate during the transmission process. Since the receiving end can only receive wireless signals with a signal strength above a certain threshold, when the network signal is attenuated too much, the receiving end will not be able to identify the wireless signal. Obstacles are the most common in wireless network environments and are an important factor that has a significant impact on network signal attenuation. Various walls, glass, and doors in the daily environment have different degrees of signal attenuation, especially metal obstacles, which are likely to completely block and reflect the propagation of wireless signals.
