Since the mobile phone can access the Internet, the strength of the WiFi signal has always been an important measure of quality of life. In order to enhance the WiFi signal, people began to delve into a variety of methods.
In many recipes, modified cans are placed on the antenna of wireless routers to enhance the WiFi signal and improve signal quality. Because of their low cost and strong operability, they are favored by many netizens. After the transformation, the WiFi signal is really better. From 1 to 2 cells, 2 to full cells are possible.
This "old" trick has been tried by few people today, but we are still curious. Can a can of a can really enhance the WiFi signal?

However, when the network speed is fast, the signal must be good. When the signal is good, the network speed may not be fast. In this case, the signal strength needs to be high, and the wireless router sends the data to the data node at a high rate. The reason does not begin to say here, under normal circumstances, the signal is good or can think that the speed will be faster.
Therefore, we not only need to observe the influence of this DIY method on the signal intensity from the experiment, but more importantly, the influence on the speed and stability of the network.
Test preparation
The final explanation is that the drawbacks of this DIY method are also very obvious, that is, the direction signal on the back of the can will be worse.
The test method is relatively simple. We set the data collection points at 0.5 meters and 35 meters from the router. We measured the signal strength, delay, and download speed of the cans with and without cans (a total of 10 acquisitions, averaging) value).
Since we use the millet router 3 with four antennas, to avoid interference, we put two 5G signal antennas and another 2.4G signal antenna down, and only keep a 2.4G signal antenna for testing. According to the principle of the whip antenna, the horizontal coverage of the upright 2.4G antenna is wider than the other three, and we can easily rule out the effect of the remaining three antennas on the signal coverage at 35 meters.

Relationship between WiFi signal strength and speed
Before doing the actual measurement, we believe that this method of half cans has a certain effect. The principle of the method is to transform the omnidirectional antenna of the wireless router into a simple directional antenna, so theoretically there will be a certain signal enhancement effect at the focal point of the can and the nearby area. Therefore, we not only need to observe the influence of this DIY method on the signal intensity from the experiment, but more importantly, the influence on the speed and stability of the network.
Test preparation
Wireless routers and aluminum cans for testing
The DIY stage is quite simple and there is not much to say here. It should be noted that the cans are cut and used, and cannot be placed entirely in the antenna. Aluminium can be made this way, be careful not to cut the hand
In addition, the wireless router is such an external whip antenna. In the case of vertical placement, the signal in the horizontal direction is the best. If the signal strength between the floors is to be enhanced, the direction of the antenna can be placed horizontally. Then set the modified cans. The final explanation is that the drawbacks of this DIY method are also very obvious, that is, the direction signal on the back of the can will be worse.
The test method is relatively simple. We set the data collection points at 0.5 meters and 35 meters from the router. We measured the signal strength, delay, and download speed of the cans with and without cans (a total of 10 acquisitions, averaging) value).
We use the AirPort utility to test the WiFi signal, speed tester delays and download speeds
It is worth mentioning that the 35-meter sampling site and the router are separated by 3 walls, and the conditions will be more demanding, but it is also more valuable. The distance of 35 meters was chosen because the WiFi signal has become very bad at this time, and the link disconnection is very likely to occur during the speed measurement, which is very suitable for testing the signal enhancement effect of the can. Since we use the millet router 3 with four antennas, to avoid interference, we put two 5G signal antennas and another 2.4G signal antenna down, and only keep a 2.4G signal antenna for testing. According to the principle of the whip antenna, the horizontal coverage of the upright 2.4G antenna is wider than the other three, and we can easily rule out the effect of the remaining three antennas on the signal coverage at 35 meters.
After the fit effect, only a 2.4G frequency antenna is used for testing
In the first test of the test results, the results obtained made us very surprised. After the cans were put on, the signal at 35 meters was almost the same as when there was no can, but the delay was significantly improved and the download speed was also greatly reduced. Note: In addition to the number of delays and link disconnection, the greater the value of the remaining data, the better
Then, we tried to make a series of adjustments to the aluminum skin curvature of the cans. We obtained better test data after many tests:
Note: In addition to the number of delays and link disconnection, the greater the value of the remaining data, the better
It can be seen that after adjusting the bending posture of the aluminum skin, most of the data are better than those without the can, especially the number of disconnections. In the course of 10 times of speed measurement, there are 5 dropped calls when there is no can, and it is necessary to Retesting the speed, and only one dropped call occurred after the adjustment, also shows that this kind of transformation really has a certain effect. As shown above, the arc of the aluminum skin is too small to affect the signal quality
The aluminum skin should be stretched as far as possible, and toward the direction in which the signal needs to be improved
However, this kind of transformation still needs patience, especially the final adjustment takes more time. And even after a toss, the benefits of improved signal and download speed are very low, which may be related to the smaller area of ​​aluminum cans we use. Directional antenna made of aluminum can
In general, cans can indeed increase WiFi signal strength, but the benefits are not high. This directional antenna production process is more complex and more challenging, but it looks very interesting.
