People in the Internet age are even more impatient, and the webpages of the webpage or the buffering of the video will make many people want to lick the keyboard. Even if we install a very high bandwidth, if the maintenance is not good in the future, the network speed will drop or drop, and several simple ways to improve the router. Wi-Fi-based wireless smart home products are beginning to gain popularity, so the stability of Wi-Fi is critical to the experience of smart home products.

First, the position adjustment method: the most simple type, often a trick to make an enemy.
1. The location where the router is placed.
Don't choose the corner of the whole house, otherwise the signal at the other end of the house must not be received well. Try to choose the center of the house, and it is better to open the area, away from more walls, doors and other obstacles. The router's signal tends to spread downwards, and placing the router high can improve coverage, so putting the router on the ground is the worst option. However, if it is a large-area duplex house with three bedrooms and two halls, then the wireless router should be placed in the stair position as much as possible to bring good wireless signals to the second floor space.
2. Antenna adjustment.
The router has two antenna modes: built-in and external. If your router has only 2 external antennas, keep one vertical and the other horizontal. This maximizes the communication distance, but if your router has only one antenna, you need to test it several times to determine the direction of the internal antenna. It is best to keep the transmit signal of the external antenna and the built-in antenna perpendicular.
3. Upgrade the antenna of the wireless router
Although more and more wireless routers use the built-in antenna design, there are still some models that have external antennas and can usually be upgraded. The signal strength of at least 2dBi to 15dBi can be enhanced by upgrading.
4. "Large pot type" cans signal amplification.
The WiFi signal amplifier sold in the market needs one or two hundred yuan. The homemade wifi signal amplifier is not a good method. An aluminum can and a pair of scissors are enough to expand the bottle into a fan shape and rewind the wireless router antenna. Insert into the drinking water of the can.
Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The Ultrasonic Transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive Ultrasonic Sensor is actually a microphone that can convert ultrasonic signal into electrical signal.
According to the working principle and materials used, the ultrasonic transducer has Piezoelectric Transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
