Is it really useful to pass online cans to enhance the routing signal?
The 360 route official conducted a test and concluded that: The self-made signal expander cans can affect the reception of the plane angle, ie the angle restricts the signal transmission direction.
The study found, Only the device on the silver side of the cans in the figure has enhanced the sensory signal. On the other device, the signal on the other side actually feels a noticeable change in its signal display. The signal will change from full to triple and display again. No signal.
Can WIFI signal booster principle: The inner surface of the can reflects radio waves, which enhances the ability of the antenna to transmit and receive signals. This is equivalent to concentrating scattered signals in one direction, but the back of the can can weaken some of the signals correspondingly.
Professor Wu Guiqing of the College of Electrical and Information Engineering of Hunan University explained that putting the cans on the antenna of the router actually turned into a problem of antenna efficiency. The cans placed on the antenna actually correspond to the pots of satellite antennas, and the satellites transmit signals through the pan. Absorb electromagnetic waves from outside, and then reflect to a focal point, so that the electromagnetic waves are more concentrated.
In fact, as long as it is a metal with emission characteristics, it can play a signal-enhancing effect. However, the self-made signal transmitter has a fatal drawback: the self-made device can not amplify the signal in all positions, but the signal will be changed if the position is not correct. weak.
Moreover, the current wireless routers on the market use very high stimulation frequencies. This makes the shape of the cans cut into place, which becomes particularly important. It needs to be verified through repeated experiments. If you need to enhance the signal or effective The way is to choose a professional signal amplifier or use an idle route for relaying or bridging, or more stable wired AP coverage.
