Antenna through the wall function and what is related to ? The antenna's through-wall function refers to the antenna's ability to accept across the wall, which is mainly determined by the following two points: One is the antenna power and frequency band, generally speaking, the more roots the stronger the signal, such as three roots is certainly stronger than one and two. The bandwidth from the manual can also be seen. There is also a kind of strengthened antenna, which is a but very long, standing up very high, about five times longer than the general antenna. This strengthened antenna radiates a very strong frequency, the same distance and the same environment, the signal can be expanded 3 times to 5 times. Compared to the router with more roots, increasing the height is more like increasing the power, which is an increase in strength. The increase in the number of roots is an increase in bandwidth and coverage area, with a different focus. Secondly, the structure of the house, such as load-bearing walls with a lot of rebar, will greatly weaken the WIFI signal (increased interference). There is also the router is best not to be placed in the corners of the house, easy to shield the signal. It is best to put it in the middle of the house or by the window (but not the corner) position. If you receive a bad signal to find ways to strengthen the power of the antenna, you can consider using an antenna amplifier to strengthen the signal.
